Role of nitric oxide-derived oxidants in vascular injury from carbon monoxide in the rat. (1/232)

Studies were conducted with rats to investigate whether exposure to CO at concentrations frequently found in the environment caused nitric oxide (NO)-mediated vessel wall changes. Exposure to CO at concentrations of 50 parts per million or higher for 1 h increased the concentration of nitrotyrosine in the aorta. Immunologically reactive nitrotyrosine was localized in a discrete fashion along the endothelial lining, and this was inhibited by pretreatment with the NO synthase (NOS) inhibitor Nomega-nitro-L-arginine methyl ester (L-NAME). The CO-induced elevations of aortic nitrotyrosine were not altered by neutropenia or thrombocytopenia, and CO caused no change in the concentration of endothelial NOS. Consequences from NO-derived stress on the vasculature included an enhanced transcapillary efflux of albumin within the first 3 h after CO exposure and leukocyte sequestration that became apparent 18 h after CO exposure. Oxidized plasma low-density lipoprotein was found immediately after CO exposure, but this was not inhibited by L-NAME pretreatment. We conclude that exposure to relatively low CO concentrations can alter vascular status by several mechanisms and that many changes are linked to NO-derived oxidants.  (+info)

Carbon monoxide poisoning treated with hyperbaric oxygen: metabolic acidosis as a predictor of treatment requirements. (2/232)

A retrospective case note analysis was made of patients who received hyperbaric oxygen for carbon monoxide poisoning and were admitted to the Royal Naval Hospital Haslar between 1991 and 1995. Males predominated (38 v 10) as did cases of deliberate self poisoning (31 v 17). The most common presenting feature was unconsciousness, which is an indication for hyperbaric oxygen and therefore reflects referral patterns. If patients had not recovered completely after one hyperbaric exposure further treatments were given. The initial hydrogen ion concentration of those requiring more than one treatment was significantly higher than those who recovered after the first treatment. The initial carboxyhaemoglobin (COHb) concentration showed only a trend to being higher in the multiple treatment group. Although metabolic acidosis is well recognised, its relationship to treatment requirements has not been shown previously. Initial COHb does not always correlate well with severity of poisoning which relates to the mechanism of toxicity of carbon monoxide: binding of carbon monoxide to the intracellular oxygen carrying proteins (for example cytochromes) rather than solely to haemoglobin. These findings are consistent with this mechanism and suggests that initial acidosis is a better predictor of treatment requirements and severity than initial COHb.  (+info)

British Hyperbaric Association carbon monoxide database, 1993-96. (3/232)

OBJECTIVES: To study the referral pattern of patients, poisoned with carbon monoxide and subsequently transferred to British hyperbaric oxygen facilities, from April 1993 until March 1996 inclusive. METHODS: A standard dataset was used by hyperbaric facilities within the British Hyperbaric Association. The data on each patient were sent in confidence to the Hyperbaric Unit at Whipps Cross Hospital for analysis. The epidemiology of poisoning and the population studied were analysed. Times of removal from exposure, referral to a hyperbaric facility, arrival at the hyperbaric facility, and start of treatment were recorded. Data on the outcome of the episode were documented in one of the contributing facilities. RESULTS: 575 patients exposed to carbon monoxide were reported as being referred to British hyperbaric facilities in the three years, the busiest facilities being in London and Peterborough. The proportions of accidental and non-accidental exposures were 1:1.05. Of the accidental exposures, central heating faults were responsible in 71.5% of cases (n = 206). Smoke inhalation from fires was responsible for a further 13.5% (n = 39). The mean delay to arrival in a hyperbaric oxygen facility was 9 hours and 15 minutes after removal from exposure. Recovery after treatment was sometimes incomplete. CONCLUSIONS: The reported pattern of referral was regionally weighted towards the south east of England. Smoke inhalation victims were often not referred for hyperbaric oxygen treatment. The delay to treatment was multifactorial; and the mean delay was well in excess of six hours. There is room for improvement in the consistency and speed of referral. Treatment schedules require standardisation. A central advice and referral service would be helpful.  (+info)

An unusual case of carbon monoxide poisoning. (4/232)

Carbon monoxide, a gas originating from incomplete combustion of carbon-based fuels, is an important cause of human deaths. In this paper, we describe an unusual carbon monoxide poisoning in a dwelling without obvious sources of combustion gases, for which two adults had to be treated in a hyperbaric chamber. Carbon monoxide readings were taken in the house and in the neighboring homes. Methane gas and nitrogen oxide levels were also monitored in the house air. Soil samples were collected around the house and tested for hydrocarbon residues. The investigation revealed the presence of a pocket of carbon monoxide under the foundation of the house. The first readings revealed carbon monoxide levels of 500 ppm in the basement. The contamination lasted for a week. The investigation indicated that the probable source of contamination was the use of explosives at a nearby rain sewer construction site. The use of explosives in a residential area can constitute a major source of carbon monoxide for the neighboring populations. This must be investigated, and public health authorities, primary-care physicians, governmental authorities, and users and manufacturers of explosives must be made aware of this problem.  (+info)

A healthy home environment? (5/232)

Over the past seven years, the U.S. Environmental Protection Agency has consistently ranked indoor air pollution among the top five risks to public health. One of the most dangerous indoor air pollutants is carbon monoxide (CO). CO can be lethal, but perhaps more important, many people suffer ill health from chronic, often undetected exposure to low levels of this gas, resulting in fatigue, headache, dizziness, nausea, and vomiting. Another dangerous pollutant is volatile organic compounds (VOCs), which come from sources including building products, cleaning agents, and paints. One VOC, formaldehyde, can act as an irritant to the conjunctiva and upper and lower respiratory tract. Formaldehyde is also known to cause nasal cancer in test animals.  (+info)

Validation of the end-expired method for measuring carboxyhaemoglobin levels for the use in occupational and environmental exposure studies. (6/232)

Carbon monoxide is one of the most common toxins encountered in work settings, the gas being emitted in situations where there is incomplete combustion of carbon-containing substances. Its acute and chronic health effects have been well-documented. While identification of dangerous situations and evaluation of control measures are conducted by environmental monitoring, the body burden due to inhalation of carbon monoxide is measured by an individual's blood carboxyhaemoglobin level. Carboxyhaemoglobin level can be measured directly from a blood sample or, indirectly, by measuring the end-expired carbon monoxide level and using the charts provided to read the corresponding carboxyhaemoglobin level. As the end-expired method is not an intervention method, and is therefore easy to conduct, it is being used widely in epidemiological studies and it could also be used for individual measurements. This study presents a better statistical method for validating the end-expired method than the correlation method used and described in previous studies.  (+info)

The clinical and functional measurement of cortical (in)activity in the visual brain, with special reference to the two subdivisions (V4 and V4 alpha) of the human colour centre. (7/232)

We argue below that, at least in studying the visual brain, the old and simple methods of detailed clinical assessment and perimetric measurement still yield important insights into the organization of the visual brain as a whole, as well as the organization of the individual areas within it. To demonstrate our point, we rely especially on the motion and colour systems, emphasizing in particular how clinical observations predicted an important feature of the organization of the colour centre in the human brain. With the use of data from functional magnetic resonance imaging analysed by statistical parametric mapping and independent component analysis, we show that the colour centre is composed of two subdivisions, V4 and V4 alpha the two together constituting the V4 complex of the human brain. These two subdivisions are intimately linked anatomically and act cooperatively. The new evidence about the architecture of the colour centre might help to explain why the syndrome, cerebral achromatopsia, produced by lesions in it is so variable.  (+info)

Carbon monoxide poisoning associated with use of LPG-powered (propane) forklifts in industrial settings--Iowa, 1998. (8/232)

In 1998, the Iowa Department of Public Health (IDPH) and Iowa State University (ISU) Extension Department, with the assistance of local health departments, investigated a series of carbon monoxide (CO) poisonings associated with the use of liquified petroleum gas (LPG)-powered forklifts in light industry. In each episode, forklifts emitting high CO concentration levels were operated in inadequately ventilated warehouse and production facilities, which resulted in high CO accumulations. Employees at each site developed symptoms of CO poisoning, and some employees received inadequate or inappropriate medical care. This report summarizes the investigations and provides recommendations to prevent such incidents.  (+info)

Berkeley Police Department determined that a South Berkeley couple found dead in their apartment died from carbon monoxide intoxication, according to a Nixle alert BPD released Friday evening.. According to the alert, Roger and Valerie Morash, who died Jan. 23 in their apartment, suffered from acute carbon monoxide intoxication. The alert called their deaths "a tragic accident.". "During the course of the investigation Berkeley police investigators collected various items within the apartment to test for toxins," the alert said. "The State of California Public Health Department determined none were present. Necropsy examinations were performed on the couples two cats. Results determined the cause of death was carbon monoxide.". Although some media outlets have previously reported that the couple died from carbon monoxide poisoning from their 3-D printer or laser cutter, officials are still investigating the source of the carbon monoxide, according to the alert.. Officials worked with the ...
The patient had carbon monoxide poisoning, which caused respiratory insufficiency, neurologic changes (loss of consciousness and visual impairment) and cardiac dysfunction (elevated troponin I, creatine kinase-MB fraction and carboxyhaemoglobin levels, and left ventricular dysfunction). Visual field defect is a significant outcome of occipital lobe infarct,(4) and the diffusion restriction observed in the left occipital lobe of our patient is evidence that the vision loss resulted from an occipital lobe ischaemic infarct.. Carbon monoxide inhibits the mitochondrial electron transport system and activates polymorphonuclear leucocytes that cause brain lipid peroxidation. This process may explain the delayed outcomes of carbon monoxide intoxication such as late encephalopathy.(5) Acute brain injury in patients exposed to carbon monoxide is usually caused by hypoxia. Neurons normally require major amounts of oxygen and glucose, and they are the cells in the central nervous system that are most ...
This double blind, randomised trial compared treatment of acute carbon monoxide poisoning with three sessions of either hyperbaric oxygen (100% oxygen at 3 atmospheres during the first session and then 2 atmospheres absolute in the subsequent two sessions) or normobaric oxygen (air at 1 atmosphere absolute during all three sessions). The incidence of neurological sequelae at 6 weeks was used as the primary outcome and assessment included a neurological examination, neuropsychological tests, and a questionnaire based on symptoms. Cognitive sequelae occurred in 25% of patients in the hyperbaric oxygen group compared with 46% in the normobaric oxygen group (unadjusted odds ratio 0.39; p=0.007). There was also a reduction in cognitive sequelae at 6 and 12 months in the hyperbaric oxygen group.. The study shows that hyperbaric oxygen therapy reduces the risk of neurological sequelae at 6 weeks and 12 months after acute carbon monoxide poisoning.. ...

Did you know that using an ethanol fireplace carries the risks of getting burned, starting a fire and suffering carbon monoxide intoxication? Ethanol fireplaces are becoming more and more popular in Quebec. They are now available through fireplace stores, hardware stores and furniture stores. They come in different forms: fireplace inserts, freestanding in steel frames, wall-mount and even portable.. Ethanol fireplaces should not be used for heat. They are decorations, and should be limited to occasional use.. Ethanol, also called bio-ethanol and ethyl alcohol, releases vapours that are flammable at room temperature. Moreover, while burning, it can generate carbon monoxide and other harmful gases. This means that you should be sure to have a portable fire extinguisher, as well as a carbon monoxide detector, not to mention a smoke detector, all of them in good working order ...
Ann Arbor, MI, April 8, 2014 /3BL Media/ - While preventable, carbon monoxide poisoning is a serious and sometimes fatal condition. Large weather events, such as snowstorms and heavy storms that cause power outages, can lead to an increase in the number of reported carbon monoxide exposures. Researchers from Hartford Hospital in Hartford, Connecticut explored the link between these major storms and the rise in carbon monoxide exposure cases. They found that portable generators were the most common source of carbon monoxide exposure after storms which resulted in power losses; car exhaust was the most frequent source of exposure after heavy snowstorms. Their findings are published in the May issue of the American Journal of Preventive Medicine.. In 2011, 12,136 unintentional exposures were reported to U.S. Poison Control Centers. Carbon monoxide is an odorless, colorless, and tasteless gas that can build up to dangerous levels in unventilated areas. Symptoms of carbon monoxide poisoning include ...

The surveys also document substantial CO exposures in the late afternoon during crowded boating conditions, mirrored by elevations in expired CO concentrations among employees and vacationers. The majority of LHC employees had estimated %COHb levels indicating the potential for adverse health effects. Vacationers tested had higher %COHb levels than employees. These results indicate that elevated %COHb levels can occur among persons in open, outdoor settings. Previously described outdoor boat-related poisonings involved dangers to occupants of individual boats (e.g., houseboats and ski-boats) (4,5). The findings in this report are subject to at least three limitations. First, evaluation of CO-related symptoms was limited by a lack of participant information on dehydration, heat stress, physical and mental stress, and vacationer alcohol ...
Eight Janesville residents were treated for carbon monoxide poisoning after firefighters responded to at least six carbon monoxide calls between Saturday and Monday.
Carbon monoxide (CO) is a colorless, odorless, poisonous gas that results from incomplete combustion of fuels (e.g., natural or liquefied petroleum gas, oil, wood, coal, or other fuels). CO sources (e.g., furnaces, generators, gas heaters, and motor vehicles) are common in homes or work environments and can put persons at risk for CO exposure and poisoning. Most signs and symptoms of CO exposure are nonspecific (e.g., headache or nausea) and can be mistakenly attributed to other causes, such as viral illnesses. Undetected or unsuspected CO exposure can result in death (1). To examine fatal and nonfatal unintentional, non--fire-related CO exposures, CDC analyzed 2001--2003 data on emergency department (ED) visits from the National Electronic Injury Surveillance System All Injury Program (NEISS-AIP) and 2001--2002 death certificate data from the National Vital Statistics System (NVSS). During 2001--2003, an estimated 15,200 persons with confirmed or possible non--fire-related CO exposure were ...
The weather outside is frightful, and the fire is so delightful…". The holiday song never seemed more true. But when the weather turns this bad we get concerned about trying to keep warm. This is the season when carbon monoxide poisonings spike. In some cases, older furnaces are pushed to their limits and alternate heat sources are used - like space heaters, ovens to heat the kitchen, wood stoves and fireplaces not normally used, gas-powered generators and electric space heaters. Some peoples cars are warmed up in the garage, allowing carbon monoxide to build up and seep into the house.. Carbon monoxide poisoning can be sneaky as well as deadly. One of its names is "the great pretender." Carbon monoxide is odorless, colorless and tasteless, so the only way to know it is present is with a carbon monoxide detector. The Poison Center recommends that each home have a working carbon monoxide detector. Early signs may seem like a virus or the flu. Be alert for these other early symptoms:. ...
Carbon monoxide can be a silent killer.People who are exposed to excessive carbon monoxide often initially exhibit such nonspecific symptoms as headache, fatigue, dizziness, nausea and vomiting that can be confused with the flu or other illnesses, said Dr. Amber Bradford, an emergency medicine physician with Akron General Medical Center.Carbon monoxide is a colorless, odorless, tasteless gas, making exposure difficult to detect.
The Ninth Circuit is set to decide whether carbon monoxide falls within the absolute pollution exclusion of a general liability insurance policy. At issue in Colony Insurance Company v. Victory Construction LLC, et al., No. 17-35357 is a ruling by an Oregon federal district court that a policy issued by Colony Insurance Company to Victory Construction LLC does not provide coverage for injury claims involving indoor carbon monoxide poisoning from a negligently installed pool heater.. The exclusion provides that the Colony policy does not apply to "[b]odily injury. . . which would not have occurred in whole or part but for the actual, alleged or threatened discharge, dispersal, seepage, migration, release or escape of hazardous materials at any time." The policy defines "hazardous materials" to include "pollutants" which was further defined to include any "gaseous or thermal irritant or contaminant." As a matter of first impression under Oregon law, the district court concluded that the plain ...
Exposing an Invisible Killer (PDF, 155 Kb). Each year in America, unintentional carbon monoxide poisoning claims more than 500 lives and sends another 15,000 people to hospital emergency rooms for treatment.1. The United States Fire Administration (USFA) and the National Association of Home Builders (NAHB) would like you to know that there are simple steps you can take to protect yourself from deadly carbon monoxide fumes.. Understanding the Risk What is carbon monoxide?. Carbon monoxide is an odorless, colorless and toxic gas. Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home. At lower levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include headaches, dizziness, disorientation, nausea and fatigue. The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure.. Where does carbon monoxide come ...

The majority of carbon monoxide exposures occur in the winter months and the most common source of residential CO-related poisoning is unvented supplemental heaters. An unvented supplemental heater is a type of space heater that uses combustible fuel and indoor air for the heating process and vents the gases produced in the heating process out into the room (instead of to the outdoors). Thus, a space heater that is improperly installed or not functioning properly can introduce carbon monoxide and other toxic fumes into the room and use up much of the oxygen in the room.. Most supplemental heaters of this type use kerosene or natural gas for fuel. While newer models have oxygen sensors that shut off the heater when the oxygen level in the room falls below a certain level, older models do not have such safety features. Because of these safety problems, unvented space heaters have been banned in several states.. Other common sources of carbon monoxide include the following:. ...
Every year, unintentional carbon monoxide (CO) poisoning (not linked to fires) sends 20,000 people to the emergency room and causes more than 4,000 hospitalizations. And, you might consider them the fortunate ones. CO also is responsible for more than 400 deaths in America each year, according to the U.S. Centers for Disease Control and Prevention….
Dubbed the "silent killer" because it is colorless, odorless, nonirritating and tasteless, carbon monoxide gas is highly toxic and exposure to it is the leading cause of accidental poisoning in the United States. Not only are carbon monoxide exposure cases on the rise and garnering large damage awards, even low-level exposure cases are demanding seven-figure settlements for brain damage and cognitive impairment-awards that can bankrupt a business.. Aided by advanced imaging and neuropsychological testing, aggressive plaintiffs lawyer are presenting high-tech evidence in support of staggering damage claims and juries are ready and willing to grant the requested awards. Targeting building owners, building associations, architects, contractors, landlords, facility managers, HVAC engineers and even equipment manufacturers when claims arise, plaintiffs lawyers are bringing individual actions as well as filing mass tort actions, pursuing many more and far larger cases.. ...
A 65 year old patient admitted with carbon monoxide poisoning developed acute pulmonary oedema during treatment with hyperbaric oxygen. After initial recovery he developed extensive intestinal ischaemia which rapidly led to death. It is suggested that intestinal vasoconstriction due to left ventricular failure made the gut much more vulnerable to the hypoxic effects of carbon monoxide than the brain and heart.. ...

Well, phenol is combustible.... C_6H_5OH(l) + 7O_2(g) rarr 6CO_2(g) + 3H_2O(l) Often when you burn this you see a black residue of carbon due to incomplete combustion. And if we wanted to represent SOME incomplete combustion we could include C(s) and CO(g) as products... C_6H_5OH(l) + 11/2O_2(g) rarr 4CO_2(g) +CO(g) + C(s)+ 3H_2O(l) Of course phenol could be selectively oxidized to quinones, but here we represent complete and incomplete combustion.
Every year, more than 40,000 Americans are bought to the emergency room because of carbon monoxide poisoning. Carbon Monoxide forms as a result of incomplete combustion of fuel, in the absence of oxygen. When fuel burns in an enclosed space, such as oil, wood and gasoline, eventually the oxygen in the room is exhausted and the end product of combustion is carbon monoxide.. Acute exposure to carbon monoxide can have severe repercussions, both physical and neurological, and even death by asphyxiation.. Our blood carries oxygen from the lungs to every cell in the body by the help of hemoglobin. Our cells thrive on oxygen and produce energy by respiration, especially the brain cells. When we inhale carbon monoxide, it reacts with hemoglobin in the blood to form carboxyhemoglobin and displaces oxygen absorbed in the hemoglobin.. This impairs the ability of the blood as a mode of transportation of oxygen. Within seconds of not receiving oxygen, brain cells begin to die, triggering a cascading effect ...
Incomplete combustion. With a good air supply, combustion should be complete and you end up with C02, without enough air (oxygen) for the fuel to combust properly, you end up with C0 - i.e. half as much oxygen in the resulting gas molecules. Your woodburner can and will produce C0 and potentially kill you, particularly if you shut it right down and let it burn slowly, as this results in incomplete combustion. Having a suitable air supply (i.e. draughty room or vent brick for over 5kW), as stated above, a well ventilated room/property, and a well sealed stove and flue can prevent it though. Best advice really is not to shut stoves down too much.. Since 2010 it has been a legal requirement of The Building Regulations to install a C0 detector in the same room as any new woodburner. That should help warn you......... ...

One of the speakers at the launch of Carbon Monoxide Awareness Week at the House of Lords in November 2012 was Dr Steven White. He gave a very interesting presentation on the long-term effects of carbon monoxide poisoning, some of which are only recently being fully realised.. Dr White has co-written a factsheet that is published on the website of Headway, the charity that works to improve life after brain injury. With Headways permission we reproduce a short extract here.. Like other types of anoxic brain injury, acute CO poisoning may lead to quite severe long-term neurological problems, with disturbances in memory, language, cognition, mood and behaviour. The damage to the basal ganglia, which is a particular feature of CO poisoning, may lead to a movement disorder resembling Parkinsons disease.. An unusual feature of acute CO poisoning is the delayed deterioration in neurological condition which may be seen in some cases, occurring anything from a few days to as long as five to six weeks ...
According to the Centers for Disease Control and Prevention, more than 500 Americans die each year from unintentional CO poisoning. Because you cant see it, smell it or taste it, you can be overcome by carbon monoxide without any warning. By ConsumerMan Herb Weisbaum.
In putting together materials design, functional testing and state-of-the art-characterization tools, were looking to develop a feedback loop," Murray said. "Improving our understanding about the active components of these catalysts can tell us what to emphasize in future systems.". Capitalizing on the Murray labs expertise in creating nanocrystals with precisely defined sizes, shapes and compositions, the researchers created a series of supported catalysts and tested them against one another on a model catalytic reaction: the oxidation of carbon monoxide.. This basic example of catalysis is also common in real-world applications, as it turns carbon monoxide, which is toxic, into carbon dioxide. Carbon monoxide is a common byproduct of the incomplete combustion of organic compounds, so it is produced in car engines and many industrial processes. Catalytic filters and converters are often required by law to cut down carbon monoxide pollution. Catalysts are often used for this reaction as simply ...

Distributed via the CDC Health Alert Network. September 02, 2017, 2130 ET (9:30 PM ET). CDCHAN-00406. Summary. Carbon monoxide (CO) is an odorless, colorless, poisonous gas that can cause sudden illness and death if present in sufficient concentration in the ambient air. During a significant power outage, persons using alternative fuel or power sources such as generators or gasoline powered engine tools such as pressure washers might be exposed to toxic CO levels if the fuel or power sources are placed inside or too close to the exterior of the building causing CO to build up in the structure. The purpose of this HAN advisory is to remind clinicians evaluating persons affected by the storm to maintain a high index of suspicion for CO poisoning. Clinicians are advised to consider CO exposure and take steps to discontinue exposure to CO. Clinicians are also advised to ask a patient with CO poisoning about other people who may be exposed to the same CO exposure, such as persons living with or ...

Students in Juniper-Poplar hall were left in the dark due to a power outage for approximately 10 hours on Sunday, but Tampa Electric Company (TECO) spokeswoman said TECO wasnt notified until 9:30 p.
Widespread power outages hit across Washington, D.C. on Tuesday, affecting government and privately-owned buildings and the citys public transit rail system intermittently early in the afternoon.
Every year, some 5,300 Swedes die premature deaths from inhaling the microscopic particles of coal, asphalt, iron and other materials that pollute the citys air. These particles, which are the result of incomplete combustion, road surface attrition, etc. could be reduced if the right steps were taken; the problem is that it is not known which particle sources pose the greatest threat to human health. To build up a picture of which particles are the most harmful, Dr Karlsson has compared how particles from a variety of sources affect cultured lung cells. The results, which are presented in her thesis Particularly harmful particles show that particles from the Stockholm underground are much more damaging to cellular DNA than the other sources tested (e.g. wood smoke and cars).. The airborne particles in the underground system largely comprise iron, and are formed by the abrasion of the train wheels against the rails. The damage is caused when these particles enter the body and form free radicals ...
SF: None in Tower 2 that I was aware of. We had a backup Generator for our Data Center on floor 97 in the event of an unplanned power outage but it had not been used during my time in the company. You have to understand how unprecedented the power down was.

The New Hampshire Fire Marshals Office says 45-year-old Michael Vanderkieft died at Massachusetts General Hospital after high carbon monoxide levels were found at his Nashua home.
Lt. Robert Deitch said the husband was found dead in the home. His wife was found unconscious in the home and was transported to Overlook Medical Center in Summit.. Deitch said the incident seems to involve exposure to carbon monoxide fumes, and police are awaiting autopsy results. Deitch said the incident is not a criminal matter.. According to a police monitoring service, officers were sent to a home at 12 Cottage Court around 1:20 p.m. Wednesday for a report of a major gas leak. The police monitoring service later indicated that an elderly couple had left their vehicle running in the garage overnight and were exposed to carbon monoxide.. Carbon monoxide is a colorless, odorless, tasteless gas.. The Chicago Tribune reported a couple in their 70s this week were found dead in their home, apparently poisoned by carbon monoxide from a car with a keyless ignition that was accidentally left running in the garage.. In April, four elderly Queens residents died from carbon monoxide exposure after a car ...
The ADT® monitored carbon monoxide detector continually senses carbon monoxide in the air with a range of 35-5,000 parts per million (PPM). When the carbon monoxide detector senses 70 PPM or more, the sensors alarm is triggered. By contrast, the first symptoms of carbon monoxide poisoning, generally slight headaches or flu-like symptoms come on at 100 PPM. The carbon monoxide detector with ADT® monitoring, when used properly, allows for early detection before carbon monoxide poisoning sets in.. This state of the art carbon monoxide detector is equipped with an 85 decibel alarm at 10 feet. The loud alert is used to notify anyone in your home of carbon monoxide buildup. The ADT® monitored carbon monoxide detector is different from the competition because it communicates with the home security panel and alerts ADT® monitoring of increased level of carbon monoxide. ADT® then follows up on the issue and will contact emergency services, as desired. This means that your familys safety isnt ...
Frequency of power outages associated with extreme events. There were fifty two reports of power outages across nineteen countries caused by extreme events during the first three months of 2013. Overall, the results from the bulletins search gave an impression of how frequent and widespread power outages are during extreme events. The events and outages occurred in both economically developed and less developed nations and in island and mainland state settings. It is interesting to note that none of the media reports contained any reference to health impacts.. The surprisingly high number of power outages reported in the PHE Extreme Events Bulletin is likely to be an under-representation of worldwide power outages. This is despite the news articles included in the PHE Extreme Events Bulletin being collected from several international media sources. These media sources include Google News, BBC, UK broadsheets and international webpages including PreventionWeb, UNISDR and ReliefWeb. While this ...
During the winter months, cold rainy weather is a reality. During these miserable weather conditions, it is important to keep in mind the threat of accidental carbon monoxide poisoning. The Monterey County Health Department would like to remind everyone that the best defense against carbon monoxide poisoning is prevention.. Carbon monoxide is a poisonous and odorless gas that does not irritate, but can kill a person in minutes. Carbon monoxide is produced whenever any fuel such as gas, oil, kerosene, wood, or charcoal is burned. "Carbon monoxide poisoning is preventable" says Dr. Hugh Stallworth, Health Officer for the Monterey County, "Generators, grills, camp stoves, or other gasoline, propane, natural gas, or charcoal-burning devices should never be used inside a home, basement, garage, or camper - or even outside near an open window.". Follow these tips to avoid accidental injury or death from carbon monoxide:. ...
The National Institutes of Health (NIH). March 1, 2016. Pregnant women with asthma may be at greater risk of preterm birth when exposed to high levels of certain traffic-related air pollutants, according to a study by researchers at the National Institutes of Health and other institutions.. The researchers observed an increased risk associated with both ongoing and short-term exposure to nitrogen oxides and carbon monoxide, particularly when women were exposed to those pollutants just before conception and in early pregnancy.. For example, an increase of 30 parts per billion in nitrogen oxide exposure in the three months prior to pregnancy increased preterm birth risk by nearly 30 percent for women with asthma, compared to 8 percent for women without asthma. Greater carbon monoxide exposure during the same period raised preterm birth risk by 12 percent for asthmatic women, but had no effect on preterm birth risk for non-asthmatics.. The last six weeks of pregnancy was another critical window for ...
Carbon Monoxide Testing and Inspection. Carbon Monoxide (CO) is a colorless, odorless, toxic gas and all fuel (gas, oil, kerosene, wood or coal) burning appliances have the potential to produce CO to some degree due to incomplete combustion. Appliances (including fire places) that are not installed, maintained, and used properly run the risk of causing CO accumulation to dangerous levels. Extreme CO exposure can cause death, considering that the gas is colorless and odorless proper detection is vitally important.. Youre A-Pro Inspector can test for Carbon Monoxide in the home as well as the appliances and fixtures that may be causing a dangerous level. Youre A-Pro Inspector will also advise you on the proper detectors and the recommended locations of the detectors as well as proper maintenance needed for offending appliances.. ...
Carbon monoxide (CO) is produced by the incomplete combustion of carbon-containing material, notably tobacco, biomass fuel and fossil fuel. The carboxyhaemoglobin (COHb) level in the blood (half-life 2 -6 hours) after inhalation of CO will depend on concentrations of inspired CO, duration of exposure, pulmonary ventilation and the COHb level before the inhalation.4 COHb is a sensitive specific physiological marker of atmospheric CO exposure from both indoor and outdoor sources.. In water-pipe smokers expired CO was reported to increase by 300% after an hour of smoking, while in cigarette smokers it only increased by 60%.5 During a single water-pipe smoking session a smoker may produce a 24-hour urinary cotinine level that is equivalent to smoking 10 cigarettes a day (95% confidence interval (CI) 7 -13 cigarettes a day).6 Contrary to popular belief, noxious substances such as nicotine, tar and heavy metals (chromium, arsenic, lead) are found in the smoke of water-pipes.7 Although water-pipe ...
COLD WEATHER INCREASES CARBON MONOXIDE HAZARDS FROM CARS. AMES, Iowa -- In cold weather do you open the overhead garage door and start the car to let it warm up for a minute or two before driving away? Thomas Greiner, an extension agricultural engineer from Iowa State University, has this warning. "Dont ever warm-up a car in a garage, even with the garage door open. In less than two minutes gas fumes build to lethal concentrations in the garage." In an attached garage, fumes can quickly spread to the house.. Deadly fumes from vehicle exhaust include carbon monoxide (CO), a colorless, odorless, tasteless, and non-irritating byproduct of incomplete combustion. Greiner has consulted on and investigated several cases of poisoning from car fumes, some resulting in death.. "When cold engines first start, they run rich," Greiner said. The catalytic converter is cold and not converting deadly carbon monoxide (CO) to carbon dioxide (CO2). Concentrations in the exhaust can be more than 80,000 parts per ...
NEW - Mandatory Carbon Monoxide Alarms in Your Home. November 1st is Carbon Monoxide Awareness Week. The Ontario government has passed a law, which came into effect on October 15, 2014, that requires a working carbon monoxide alarm in your home, specifically, outside all sleeping areas, if you have a fireplace, any fuel-burning appliance, or an attached garage.. Carbon monoxide is a poisonous and very dangerous gas because you cant smell or taste it. The symptoms of CO poisoning are gradual, you may start to feel ill and tired. If you are already asleep, you would simply just not wake up.. Any appliance or device that runs on fuel, including propane and wood, can produce this deadly gas. Vehicles running in an attached garage with the door between it and the home left open, or if there is any breach in the wall between the two areas will also allow Carbon Monoxide to enter your home.. Helpful Fact Sheets:. ...
Early this month a teenage boy died and 14 others were hospitalized for carbon monoxide poisoning due to a malfunctioning indoor pool heater. While this tragedy is shocking, it is unfortunately not the first time this has happened. Carbon monoxide is produced when fuel is burned, and when too much of it is present in the air, it replaces oxygen within our red blood cells causing significant tissue and muscle damage. Prolonged exposure to carbon monoxide can cause massive brain damage and death. Some of the symptoms of carbon monoxide poisoning are dizziness, weakness, fatigue, vomiting, and confusion. If you believe you are experiencing any of these symptoms, you must get yourself to an open air space as soon as possible before you are rendered unconscious. With proper installation, ventilation and maintenance, there should never be any issues with a carbon monoxide leak from a pool heater causing personal injury. Sadly in these cases, malfunctioning machinery and negligence may have formulated ...
Carbon Monoxide Poisoning in Children Approximately nine children die each year from non-fire related carbon monoxide poisoning. Carbon monoxide poisoning is the most common cause of accidental poisoning-related deaths and is often called the silent killer. What causes carbon monoxide poisoning?

Shuniah - At approximately 1:00pm on Sunday, February 19, 2017, Superior North EMS Paramedics attended a residence in Shuniah to assist a female in her 50s with a medical emergency. While attending to the patient their Monitor/Defibrillator alarmed indicating dangerous levels of Carbon Monoxide in the residence. The patient was transported to the hospital and her condition started to improve with fresh air and oxygen. The other two residents showed no signs Carbon Monoxide sickness and attended the hospital with the patient.. Shuniah Fire and Emergency Services responded quickly to the residence and found high levels of Carbon Monoxide, it was unsure at the time if the wood stove or the oil burning furnace was the cause of the Carbon Monoxide. An older Carbon Monoxide detector was present but not working. It was later determined that the wood stove may have been the cause with a down draft situation.. Having the furnace checked annually can ensure that your home, your family and even your pets ...
OFTEC Manager David Blevings said; "Carbon Monoxide is a highly poisonous gas which in high levels can kill in as little as three minutes earning it the name the silent killer. We fully support carbon monoxide safety month and are working hard to raise awareness of how to prevent carbon monoxide poisoning and keep people safe.. "With 50 people every year dying from carbon monoxide poisoning in the UK, it is vital that householders understand the importance of checking their home heating systems annually for leaks, damage or defects, including oil or gas boilers as well as solid fuel appliances. "The Health and Safety Executive advises that all heating appliances should be serviced annually by an OFTEC Registered Technician to ensure maximum efficiency and to make sure the appliance is not leaking carbon monoxide. Householders face a greater risk if they have appliances fixed by so-called cowboys who may not be qualified or deemed competent to work in your home. You cant detect CO without ...
All Iowans are being reminded about the importance of carbon monoxide detectors after the weekend deaths of two people in Mason City. The towns fire chief Bob Platts says there was a big push to put carbon monoxide detectors in homes 15 to 20 years ago, and if yours is that old, its overdue to be replaced. "Carbon monoxide detectors, similar to smoke detectors, they do have a shelf life and when theyre used, they are good for about five years, so Im guessing theres probably a number of them out there that probably are not up to date," he says.. Platts says if you are going to have a carbon monoxide detector in your home, make sure its installed in a proper place. He suggests placing it in a sleeping area or a common area like in a hallway in between bedrooms. He says you should hang it about five feet off the floor because thats about the level that C-O is mixing with air.. Platts says you wont be able to notice carbon monoxide in your home without a detector. "Its colorless and ...

Never use a natural gas stove, oven or charcoal grill as an indoor heat source.. Exposure to CO can cause flu-like symptoms, including headache, dizziness, weakness, nausea and loss of muscle control. Prolonged exposure to CO can lead to serious illness and even death.. CO is produced by incomplete combustion from boilers, furnaces, water heaters, gasoline engines, stoves, generators, lanterns and natural gas ranges. The incomplete combustion of charcoal, oil, wood or propane also can produce CO, which may reach dangerous levels in enclosed or partially-enclosed spaces and poorly ventilated areas. Anyone who suspects a carbon monoxide problem should get up, get out and call 911. NYSEG customers may also call 1.800.572.1121; RG&E customers may call 1.800.743.1702 ...
The specific gravity of Carbon Monoxide is 0.9657 (with normal air being 1.0), this means that it will float up towards the ceiling because it is lighter than regular air. However, when a build up of dangerous levels of CO gas is taking place, this is nearly always due to a heat source that is not burning its fuel correctly (motor vehicle exhaust fumes are an exception). This heated air can form a layer near your ceiling which can prevent the Carbon Monoxide from reaching a ceiling detector.. For this reason I strongly suggest that it is best to mount your detectors on the walls at least a couple of feet below the height of the ceiling. If your detector has a digital read-out, then I recommend placing it at about eye level so you can easily read it. Or if you have some other structure, like the exposed beam in this photograph insdide my house which is positioned below the ceiling level, then you can attach your carbon monoxide detectors to it instead.. ...
When we breathe it, carbon monoxide combines with with the red blood cells in the blood and displaces the oxygen our bodies need to survive. Carbon monoxide combines with the red blood cells over 200 times more easily than oxygen and creates a condition known as carboxyhemoglobin saturation. Carbon monoxide, instead of oxygen, then enters the vital organs through the bloodstream. Our organ tissues require oxygen; without it, our organs start to asphyxiate or suffocate. It takes the body much longer to eliminate carbon monoxide, however its absorption is very fast. ...
The All-Party Parliamentary Carbon Monoxide Group and Policy Connect report identifies that symptoms of carbon monoxide (CO) poisoning are not routinely being detected in the healthcare system.. The All-Party Parliamentary Carbon Monoxide Group, co-chaired by cross bench Peer, Professor the Baroness Finlay of Llandaff, and Huddersfield MP Barry Sheerman, asked a group of health experts to identify ways of improving the diagnosis of CO poisoning. This is due to health figures showing that every year at least 4,000 people in England and Wales attend emergency departments (EDs) as the result of accidental CO poisoning.. Health experts know that CO exposure leads to more than 30 people a year losing their lives and 200 people being admitted to hospital. But it is not yet known how many undiagnosed cases return home, become ill again, or die from continued exposure to CO. The experts believe these figures could be a gross underestimation and the actual cost to the NHS is likely to be much more than ...

Carbon monoxide is produced from the partial oxidation of carbon-containing compounds; it forms when there is not enough oxygen to produce carbon dioxide (CO2), such as when operating a stove or an internal combustion engine in an enclosed space. In the presence of oxygen, including atmospheric concentrations, carbon monoxide burns with a blue flame, producing carbon dioxide.[11] Coal gas, which was widely used before the 1960s for domestic lighting, cooking, and heating, had carbon monoxide as a significant fuel constituent. Some processes in modern technology, such as iron smelting, still produce carbon monoxide as a byproduct.[12] A large quantity of CO byproduct is formed during the oxidative processes for the production of chemicals. For this reason, the process off-gases have to be purified. On the other hand, considerable research efforts are made in order to optimize the process conditions,[13] develop catalyst with improved selectivity [14] and to understand the reaction pathways ...
... poisoning occurs when a flue or fuel burning appliance such as multi-fuel stove, gas cooker, boiler or open fire has not been properly installed, maintained or is poorly ventilated..

Carbon Monoxide The presence of carbon monoxide (CO) in our homes is dangerous. So, how can you protect your family from carbon monoxide? How do you choose the right CO detector for your home? The first step is to make sure that carbon monoxide never enters your home. The second step is to install at least one CO detector in your home. This About Your House answers often-asked questions about carbon monoxide to help you make the right decision to make your home safe. What Is Carbon Monoxide? Carbon monoxide (CO) is a colourless and odourless gas. Because you cant see, taste or smell it, it can affect you or your family before you even know its there. Even at low levels of exposure, carbon monoxide can cause serious health problems. CO is harmful because it will rapidly accumulate in the blood, depleting the ability of blood to carry oxygen.1 Where Does Carbon Monoxide Come From? Carbon monoxide is a common byproduct of the combustion (burning) of fossil fuels. Most fuel-burning equipment ...
The main indoor air pollutant that can cause headaches is carbon monoxide. Environmental tobacco smoke and volatile organic compounds can also cause headaches, but irritant symptoms of the eyes and throat are likely to be more prominent with those sources. The most common symptoms of carbon monoxide inhalation include headache, dizziness, weakness, nausea, difficulty in concentrating, shortness of breath and visual changes. Less frequent symptoms include chest pain, loss of consciousness, abdominal pain and muscle cramping.2 The circulatory and nervous systems are often affected because of their fixed oxygen needs: patients who have inhaled carbon monoxide may present with signs of myocardial ischemia, hypotension, congestive heart failure, arrhythmias, mental confusion, clumsiness, emotional lability, impaired judgement, diminished visual acuity, stupor or coma.20 Carbon monoxide poisoning is considered a "disease with a thousand faces." 20 Its classic mask - cherry-red lips, cyanosis and ...

We spend most of our time indoors whether we are at home or at work. Most of the time, we spend most of our time at home. Indoor air pollution is becoming a problem that many are starting to understand since we spend a great amount indoors. We start to notice these problems either when we smell odors or feel several symptoms that can link to unhealthy indoor air. One substance that is dangerous for our indoor air is carbon monoxide. Carbon Monoxide destroys air quality. Carbon Monoxide is a colorless and odorless gas. Low levels and high levels of carbon monoxide inside a home can cause flu like symptoms to headaches and can cause death.Since carbon monoxide is a dangerous gas and you cannot smell it or see it, it is important to have a carbon monoxide alarm.. In California, the Carbon Monoxide Detection Act of 2010 made it possible for all homes to require a carbon monoxide detection device. As of last year, all multi-family units were required to install Carbon Monoxide detectors, even if the ...
Carbon monoxide is a common by-product of combustion, present whenever fossil fuels are burned. It is produced by malfunctioning or un-vented gas or oil home appliances such as furnaces, clothes dryers, ranges, ovens, water heaters and space heaters, as well as fireplaces, charcoal grills and wood burning stoves. Automobile exhaust also contains high levels of carbon monoxide that can seep into a home if a car is left running in an attached garage. All of these sources can contribute to a CO problem in the home.. Usually, carbon monoxide is vented safely to the outside. However, insulation meant to keep indoor air warm during the winter or cool in the summer can help trap CO-polluted air in the home. Furnace heat exchangers can crack; vents and chimneys may reverse direction causing a downdraft, which traps combustion gases in the home.. How can I protect my family? ...
Objectives: Exposure to air pollution is associated with numerous impacts on health, including neurodevelopmental function. The purpose of this study was to estimate the magnitude of air pollution exposure based on environmental carbon monoxide (CO) measures and assessment of 1-hydroxypyrene (1-OHP), a metabolite of polycyclic aromatic hydrocarbons (PAHs), among school-aged HIV-infected and uninfected children in peri urban Kenya and to examine the impacts of these exposures on neurodevelopment. Methods: We conducted a cross sectional study of 49 HIV uninfected unexposed (HUU) and 45 HIV infected children ages 5-9 and their caregivers in Nairobi, Kenya. We used a battery of neurodevelopmental tests to assess function in 9 domains. Caregiver 24-h personal CO exposure was a proxy for child exposure, and measured child urinary 1-OHP. Results: Mean 24-h CO exposure was 8.15 ±13.46 ppm and mean urine 1-OHP was 0.81±0.60 µmol/mol creatinine. Overall, 39.4% of children had mean CO exposure ,WHO ...
The two employees at a blinds showroom on Whalley New Road, Blackburn were taken to hospital on 8 December 2010 after suffering from headaches and nausea for several months.. Tests showed both men had elevated levels of carbon monoxide in their blood, and one had to be kept in overnight and treated with oxygen.. The buildings landlord, Mohammed Asghar, 46, was prosecuted by the Health and Safety Executive (HSE) after an investigation found he had failed to ensure the gas heater he provided at the showroom was safe.. During a two-day trial, Blackburn Magistrates Court heard that the men became concerned they might have been exposed to carbon monoxide when they searched their symptoms on the internet.. The level of carbon monoxide in one of the workers blood was more than three times the normal level, despite being measured at the hospital hours after he was last exposed to the gas.. The gas heater was found to be immediately dangerous when a National Grid engineer visited the showroom, and the ...

The chambers are full of 100 percent oxygen, compared to the 21 percent in the normal atmosphere. "The goal is to get the carbon monoxide out of the system as fast as possible," said Dr. Adurty.. Carbon monoxide is a colorless, odorless gas that can be deadly. Dr. Adurty says it can make people sick in a matter of minutes. Faulty furnaces are one possible source.. ...
Automobiles, heaters, cooking appliances, and other everyday items that burn fuel produce carbon monoxide when they run. This gas is normally vented out of buildings and cars long before it poses any health risk, but this cannot happen if exterior vents are blocked by snow, ice, or debris. Carbon monoxide is deadly in high quantities. Because the gas cannot be seen, smelled, or tasted, it is extremely important that all exterior home heating vents and vehicle tailpipes be cleared completely, and that smoke and carbon monoxide detectors are tested to ensure they have batteries and are working.. ...
Carbon Monoxide (CO) is an odorless, colorless and tasteless gas. Carbon monoxide poisoning is caused when CO builds up in the bloodstream, preventing the body from using oxygen. This can cause damage to your severe organs, and possibly death. Because you cannot see, taste, or smell it, people often do not realize that they are breathing CO. The only way to know if CO is in your home is with a CO detector. Therefore, its important for families to have CO detectors installed on every level of their home, and to know how to prevent carbon monoxide poisoning. ...
Description: Carboxyhemoglobin, a complex of hemoglobin and carbon monoxide, is a marker of exposure to inhaled carbon monoxide (CO). CO gas is produced from almost any fire as the result of incomplete combustion to CO2, and the normal individual will have about 1 or 2 % of their hemoglobin in the form of carboxyhemoglobin, and up to 5% depending on environmental circumstances. Smokers can have levels as high as 10% or even higher. Poisoning with CO generally results from improperly vented furnaces, automobile exhaust, and fires, with carboxyhemoglobin:hemoglobin ratios of 10-30% found in symptomatic individuals and 30-90% in fatalities. With a 230 fold greater affinity, inhaled CO avidly replaces oxygen at its hemoglobin binding site. In addition, replacing even one of the 4 sites of the hemoglobin tetramer with CO prevents dissociation of the remaining 3 oxygen moieties to tissue (known as left shift of O2 dissociation curve). As a result, hemoglobin remains red and skin color is rosy despite ...

During the time these data were collected by MOPITT, other satellite sensors observed heavy, widespread particulate pollution over this region. Along with smoke and particulate emissions, carbon monoxide is a byproduct of burning biomass and fossil ...
Knowing your carbon monoxide detector is working properly is a serious matter. You can test a carbon monoxide detector to ensure it can identify the level of carbon monoxide (CO) in the air, measured in parts per million (ppm). Pressing the Test button on the detector will only tell you whether the device has adequate electrical power from an outlet or batteries.
Installing your Carbon Monoxide Detector is relatively straight forward, but there are some important differences to installing a smoke detector. Before going any further we strongly suggest you read about where to install carbon monoxide detectors. This is an important first step because incorrect positioning can result in complete failure for your carbon monoxide sensor to work, and can also result in false alarms.

Title:Application of Carbon Monoxide for Transplantation. VOLUME: 13 ISSUE: 6. Author(s):Atsunori Nakao and Yoshiya Toyoda. Affiliation:E1551, Biomedical Science Tower, 200 Lothrop Street, Pittsburgh, PA, 15213, USA.. Keywords:Carbon monoxide, transplantation, ischemia reperfusion, rejection. Abstract:Carbon monoxide (CO) is an invisible, chemically inert, colorless and odorless gas and is toxic at high concentrations due to its interference with oxygen delivery. However, CO is endogenously and physiologically generated in mammalian cells via the catabolism of heme in a rate-limiting step of heme oxygenase systems, and CO potently protects against cellular injury. CO relaxes blood vessels and exerts anti-thrombotic effects by inhibiting platelet aggregation and derepressing fibrinolysis. In addition, CO reduces ischemia/reperfusion injury and inflammatory responses. CO inhibits apoptosis of endothelial and epithelial cells and reduces proliferation of smooth muscle cells, fibroblasts and T ...

At any time of the year, carbon monoxide is referred to as "the silent killer" because it cant be seen or smelled, but at high levels it can kill a person in minutes. Hundreds of people die accidentally every year from carbon monoxide poisoning caused by malfunctioning or improperly used fuel-burning appliances. Even more die from carbon monoxide produced by idling cars. Pregnant women, infants, the elderly, and people with anemia or with a history of heart or respiratory disease can be especially susceptible. Read More ...
