Carboxyhemoglobin
Carbon Monoxide Poisoning
Toxic asphyxiation due to the displacement of oxygen from oxyhemoglobin by carbon monoxide.
Methemoglobin
Carbon Monoxide
Carbon monoxide (CO). A poisonous colorless, odorless, tasteless gas. It combines with hemoglobin to form carboxyhemoglobin, which has no oxygen carrying capacity. The resultant oxygen deprivation causes headache, dizziness, decreased pulse and respiratory rates, unconsciousness, and death. (From Merck Index, 11th ed)
Sulfhemoglobin
Oximetry
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
Methylene Chloride
A chlorinated hydrocarbon that has been used as an inhalation anesthetic and acts as a narcotic in high concentrations. Its primary use is as a solvent in manufacturing and food technology.
Hemoglobins
The oxygen-carrying proteins of ERYTHROCYTES. They are found in all vertebrates and some invertebrates. The number of globin subunits in the hemoglobin quaternary structure differs between species. Structures range from monomeric to a variety of multimeric arrangements.
Smoke Inhalation Injury
Pulmonary injury following the breathing in of toxic smoke from burning materials such as plastics, synthetics, building materials, etc. This injury is the most frequent cause of death in burn patients.
Methemoglobinemia
The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)
Oxyhemoglobins
A compound formed by the combination of hemoglobin and oxygen. It is a complex in which the oxygen is bound directly to the iron without causing a change from the ferrous to the ferric state.
Blood Gas Monitoring, Transcutaneous
The noninvasive measurement or determination of the partial pressure (tension) of oxygen and/or carbon dioxide locally in the capillaries of a tissue by the application to the skin of a special set of electrodes. These electrodes contain photoelectric sensors capable of picking up the specific wavelengths of radiation emitted by oxygenated versus reduced hemoglobin.
Dithionite
Dithionite. The dithionous acid ion and its salts.
Barium Compounds
Inorganic compounds that contain barium as an integral part of the molecule.
Potassium Compounds
Inorganic compounds that contain potassium as an integral part of the molecule.
Chromatography, Gas
Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
Spectrophotometry
The art or process of comparing photometrically the relative intensities of the light in different parts of the spectrum.
Photolysis
Chemical bond cleavage reactions resulting from absorption of radiant energy.
Smoking
Inhaling and exhaling the smoke of burning TOBACCO.
Jaundice, Neonatal
Yellow discoloration of the SKIN; MUCOUS MEMBRANE; and SCLERA in the NEWBORN. It is a sign of NEONATAL HYPERBILIRUBINEMIA. Most cases are transient self-limiting (PHYSIOLOGICAL NEONATAL JAUNDICE) occurring in the first week of life, but some can be a sign of pathological disorders, particularly LIVER DISEASES.
Jaundice
A clinical manifestation of HYPERBILIRUBINEMIA, characterized by the yellowish staining of the SKIN; MUCOUS MEMBRANE; and SCLERA. Clinical jaundice usually is a sign of LIVER dysfunction.
Bilirubin
A bile pigment that is a degradation product of HEME.
Jaundice, Obstructive
Jaundice, the condition with yellowish staining of the skin and mucous membranes, that is due to impaired BILE flow in the BILIARY TRACT, such as INTRAHEPATIC CHOLESTASIS, or EXTRAHEPATIC CHOLESTASIS.
Kernicterus
A term used pathologically to describe BILIRUBIN staining of the BASAL GANGLIA; BRAIN STEM; and CEREBELLUM and clinically to describe a syndrome associated with HYPERBILIRUBINEMIA. Clinical features include athetosis, MUSCLE SPASTICITY or hypotonia, impaired vertical gaze, and DEAFNESS. Nonconjugated bilirubin enters the brain and acts as a neurotoxin, often in association with conditions that impair the BLOOD-BRAIN BARRIER (e.g., SEPSIS). This condition occurs primarily in neonates (INFANT, NEWBORN), but may rarely occur in adults. (Menkes, Textbook of Child Neurology, 5th ed, p613)
Phototherapy
Treatment of disease by exposure to light, especially by variously concentrated light rays or specific wavelengths.
Hyperbilirubinemia
A condition characterized by an abnormal increase of BILIRUBIN in the blood, which may result in JAUNDICE. Bilirubin, a breakdown product of HEME, is normally excreted in the BILE or further catabolized before excretion in the urine.

Role of nitric oxide-derived oxidants in vascular injury from carbon monoxide in the rat. (1/461)

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)

High predictive value of red cell volume measurement using carboxy-haemoglobin in a rabbit model of haemorrhage. (2/461)

We have studied the accuracy of blood volume measurements using carbon monoxide (CO)-labelled haemoglobin (COHb) injection and dilution (CO method) by comparing changes in red cell volume (RCV) measured using the CO method and 51Cr-labelled erythrocyte dilution (51Cr method) in a haemorrhage and infusion model in rabbits. RCV was measured repeatedly using the CO method at four different blood volume stages (stages I-IV). At stages I and IV, RCV was measured simultaneously using the 51Cr method. In comparing the sum of the circulating RCV and extracted RCV (SUM RCV) using the CO method, the values were almost equal and there were no significant differences between the values at the four stages. In comparing circulating RCV measured using the CO method and the 51Cr method, mean difference between the two methods was 0.80 (SD 0.76) ml kg-1 or 4.7 (4.6)%, and a positive correlation was observed (r = 0.91). We conclude that the CO method can be used to measure blood volume during perioperative periods in infants because it avoids use of a radioactive tracer, is simple and repeated measurements are possible.  (+info)

A physiological model for predicting carboxyhemoglobin formation from exposure to carbon monoxide in rats. (3/461)

A time-dependent simulation model, based on the Coburn-Forster-Kane equation, was written in Advanced Continuous Simulation Language to predict carboxyhemoglobin (HbCO) formation and dissociation in F-344 rats during and after exposure to 500 parts/million CO for 1 h. Blood-gas analysis and CO-oximetry were performed on samples collected during exposure and off-gassing of CO. Volume displacement plethysmography was used to measure minute ventilation (VE) during exposure. CO diffusing capacity in the lung (DLCO) was also measured. Other model parameters measured in the animals included blood pH, total blood volume, and Hb concentration. Comparisons between model predictions using values for VE, DLCO, and the Haldane coefficient cited in the literature and predictions using measured VE, DLCO, and calculated Haldane coefficient for individual animals were made. General model predictions using values for model parameters derived from the literature agreed with published HbCO values by a factor of 0.987 but failed to simulate experimental data. On average, the general model overpredicted measured HbCO level by nearly 9%. A specific model using the means of measured variables predicted HbCO concentration within a factor of 0.993. When experimentally observed parameter fluctuations were included, the specific model predictions reflected experimental effects on HbCO formation.  (+info)

Neonatal bilirubin production, reflected by carboxyhaemoglobin concentrations, in Down's syndrome. (4/461)

AIM: To determine whether increased bilirubin production, reflected by blood carboxyhaemoglobin (COHb) values, is responsible for hyperbilirubinaemia in cases of Down's syndrome with no obvious cause for excessive jaundice. METHODS: Blood was sampled on the third day of life for COHb, total haemoglobin (tHb), and serum total bilirubin, from 19 consecutively born neonates with Down's syndrome (a subset of 34 term babies), who had developed hyperbilirubinaemia (serum bilirubin >/= 256 micromol), and from 32 term controls. COHb, measured by gas chromatography, was corrected for inspired CO (COHbc) and expressed as a percentage of tHb. RESULTS: Significantly more of the Down's syndrome subset developed hyperbilirubinaemia than the controls (10/19 (52%) vs 7/32 (22%), relative risk 2.4, 95% confidence intervals (CI) 1.10 to 5.26). Third day serum bilirubin values (mean (SD)) were higher in the Down's syndrome neonates than in controls (214 +- 63 micromol/l vs 172 +- 54 micromol/l, respectively, p=0.015). Mean (SD) COHbc values were significantly higher in the Down's syndrome neonates than in controls (0.92 +- 0. 24% vs 0.63 +- 0.17%; p<0.0001). However, Down's syndrome neonates who became hyperbilirubinaemic had similar COHbc values to those who did not (0.87 +- 0.26% and 0.95 +- 0.23%, respectively). These values contrast with those of the controls, in whom a significant increase in COHbc was associated with hyperbilirubinaemia (0.74 +- 0. 15% vs 0.60 +- 0.16%, respectively; p<0.05). tHb values were similar in both groups. CONCLUSIONS: Down's syndrome neonates had a greater risk of hyperbilirubinaemia, and higher COHbc values, than controls. However, excessive bilirubin production could not be exclusively responsible for the hyperbilirubinaemia. By inference, decreased bilirubin elimination probably plays a greater part in its pathogenesis than in controls. Down's syndrome neonates may have abnormal erythropoiesis, leading to increased haem turnover.  (+info)

Validation of the end-expired method for measuring carboxyhaemoglobin levels for the use in occupational and environmental exposure studies. (5/461)

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)

Methylene chloride poisoning in a cabinet worker. (6/461)

More than a million workers are at risk for methylene chloride exposure. Aerosol sprays and paint stripping may also cause significant nonoccupational exposures. After methylene chloride inhalation, significant amounts of carbon monoxide are formed in vivo as a metabolic by-product. Poisoning predominantly affects the central nervous system and results from both carboxyhemoglobin formation and direct solvent-related narcosis. In this report, we describe a case of methylene chloride intoxication probably complicated by exogenous carbon monoxide exposure. The worker's presentation of intermittent headaches was consistent with both methylene chloride intoxication and carbon monoxide poisoning. The exposures and symptoms were corroborated by elevated carboxyhemoglobin saturations and a workplace inspection that documented significant exposures to both methylene chloride and carbon monoxide. When both carbon monoxide and methylene chloride are inhaled, additional carboxyhemoglobin formation is expected. Preventive efforts should include education, air monitoring, and periodic carboxyhemoglobin determinations. Methylene chloride should never be used in enclosed or poorly ventilated areas because of the well-documented dangers of loss of consciousness and death.  (+info)

Effects of exposure to low concentrations of carbon monoxide on exercise performance and myocardial perfusion in young healthy men. (7/461)

OBJECTIVE: To assess the effects of exposure to low concentrations of carbon monoxide (CO), as commonly measured in atmospheric urban air pollution and certain occupational environments, on exercise performance and myocardial perfusion in young healthy men, and the possible need for tighter restrictions on ambient concentrations of CO. METHODS: 15 young, healthy non-smoking men, 18-35 years old, were exposed blindly and randomly to air or to a mixture of CO and air, followed by an exercise treadmill test with thallium heart scintigraphy. Blood was drawn for determination of carboxyhaemoglobin before and at the end of the exposure, and for lactic and pyruvic acid at the beginning and the end of the exercise test. The main outcome measures include the duration of the exercise test, the maximal effort expressed in metabolic equivalent units (METs), the mean plasma lactic to pyruvic acid ratio at the end of the ergometry, ECG changes in the exercise test, and perfusion deficits in thallium heart scintigraphy. RESULTS: At the end of exposure to CO, the mean (SD) blood carboxyhaemoglobin concentration rose from 0.59% (0.08%) to 5.12% (0.65%) (p < 0.0001). At the end of the exercise period, the mean (SD) plasma lactate/pyruvate ratio, which reflects the level of anaerobic metabolism (69.9 (5.9) after air and 75.9 (7.0) after CO), was not significantly different between the two experimental groups. Exercise induced electrocardiographic changes were noted in only one subject after exposure to CO. No arrhythmias were detected in any of the subjects. Significant differences were found in the mean duration of the exercise test (p = 0.0012) and the METs (p = 0.0001). The mean adjusted difference of exercise duration between exposure to air and CO was 1.52 minutes 95% confidence interval (95% CI) 0.73 to 2.32 minutes. The mean adjusted difference of METs between exposure to air and CO was 2.04 95% CI 1.33 to 2.76. The models for duration of exercise and METs showed no significant sequence and period effects. Thallium myocardial perfusion imaging disclosed normal perfusion in all regions of the heart, with no significant differences in perfusion between the two exercise tests (after air or CO). CONCLUSION: Acute exposure to a low concentration of CO which produces blood carboxyhaemoglobin concentrations of 4%-6% significantly decreases exercise performance in young healthy men. No ischaemic electrocardiographic changes or disturbances in myocardial perfusion were found by graded exercise with thallium scintigraphy. Our findings suggest that pollution of atmospheric air by CO at concentrations which are commonly found in urban and industrial environments may exert an adverse effect on skeletal muscles, manifesting as decreased exercise performance.  (+info)

UV resonance raman spectra of ligand binding intermediates of sol-gel encapsulated hemoglobin. (8/461)

We report for the first time specific conformational changes for a homogeneous population of ligand-bound adult deoxy human hemoglobin A (HbA) generated by introducing CO into a sample of deoxy-HbA with the effector, inositol hexaphosphate, encapsulated in a porous sol-gel. The preparation of ligand-bound deoxy-HbA results from the speed of ligand diffusion relative to globin conformational dynamics within the sol-gel (1). The ultraviolet resonance Raman (UVRR) difference spectra obtained reveal that E helix motion is initiated upon ligand binding, as signaled by the appearance of an alpha14beta15 Trp W3 band difference at 1559 cm(-1). The subsequent appearance of Tyr (Y8a and Y9a) and W3 (1549 cm(-1)) UVRR difference bands suggest conformational shifts for the penultimate Tyralpha140 on the F helix, the "switch" region Tyralpha42, and the "hinge" region Trpbeta37. The UVRR results expose a sequence of conformational steps leading up to the ligation-induced T to R quaternary structure transition as opposed to a single, concerted switch. More generally, this report demonstrates that sol-gel encapsulation of proteins can be used to study a sequence of specific conformational events triggered by substrate binding because the traditional limitation of substrate diffusion times is overcome.  (+info)

Carboxyhemoglobin and Methemoglobin as Markers of Postoperative Pulmonary ComplicationsCarboxyhemoglobin and Methemoglobin as Markers of Postoperative Pulmonary Complications
Introduction: The inhalation of tobacco smoke can substantially raise the level of carboxyhemoglobin in the blood. Determination of the level of carboxyhemoglobin and methemoglobin can identify patients with increased risk for development of postoperative pulmonary complications. Material and Methods: Thirty patients scheduled for elective urologic surgery under general endotracheal anesthesia were allocated in two groups (n = 15 each). The study group comprised patients who were smoking cigarettes or tobacco pipe, while the control group included non-smokers. In both groups carboxyhemoglobin and methemoglobin levels were determined preoperatively, after preoxygenation, and one hour after completing the anesthesia. Postoperative pulmonary complications were assessed and recorded during the period of hospitalization.Results: The average values of carboxyhemoglobin between the two groups were statistically significantly different. Postoperative carboxyhemoglobin was higher in smokers compared to

Carboxyhaemoglobin levels in water-pipe and cigarette smokersCarboxyhaemoglobin levels in water-pipe and cigarette smokers
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 ...

Clinically severe jaundice due to ABO incompatibility can occur when infants with blood type A or B are born to mothers with type O blood. An estimated 20 percent of pregnancies are ABO incompatible, but only a very small proportion of blood type A or B babies born to O type mothers develop overt ABO hemolytic disease. Despite the relative rarity of ABO hemolytic disease, it is common practice among pediatricians and family practice physicians to perform routine blood typing and antibody screening on all newborns born to type O mothers.. A very accurate and reliable laboratory measure of red blood cell destruction is the plasma carboxyhemoglobin level (COHb). COHb levels can be determined using a minute amount of blood, obtained at the same time the newborns heel is pierced to obtain blood for the mandatory newborn screen (performed on all newborns prior to discharge) in order to avoid an additional invasive procedure.. Our hope is to determine whether routine blood typing and anti-globulin ...

The effects of carbon monoxide on exercise tolerance as assessed by the distance walked in 12 minutes were studied in 15 patients with severe chronic bronchitis and emphysema (mean forced expiratory volume in one second 0.56 1, mean forced vital capacity 1.54 1). Each subject walked breathing air and oxygen before and after exposure to sufficient carbon monoxide to raise their venous carboxyhaemoglobin concentration by 9%. There was a significant reduction in the walking distance when the patients breathed air after exposure to carbon monoxide (p less than 0.01), and the significant increase in walking distance seen after exercise when breathing oxygen at 2 1/minute via nasal cannulae was abolished if carbon monoxide has previously been administered. Thus concentrations of carboxyhaemoglobin frequently found in bronchitic patients who smoke may reduce their tolerance of everyday exercise, possibly by interfering with the transport of oxygen to exercising muscles. ...

During aircraft interior fires, carbon monoxide CO and hydrogen cyanide HCN are produced in sufficient amounts to cause incapacitation and death. Time-to-incapacitation ti is a practical parameter for estimating escape time in fire environments. Exposures to CO-HCN mixtures have demonstrated that these gases have additive effects producing shorter times to incapacitation, but the resulting concentrations of carboxyhemoglobin COHb and blood cyanide CN- at incapacitation are not well defined. These undefined relationships between COHb and blood CN- levels and the onset of incapacitation make the interpretation of postmortem levels difficult for medical accident investigators. To explore these relationships, ti was determined in laboratory rats exposed to 2 CO-HCN mixtures consisting of CO and HCN concentrations that produce 5- and 35-min ti in individual gas exposures COHb and blood CN- concentrations were determined at incapacitation. In the high concentration CO- HCN mixture, the resultant ti was

Increasing the dose rate of nitrate increased the fraction of methaemoglobin in the blood of steers (P = 0.014). A highly significant effect was demonstrated for the interaction of dose rate x day (P , 0.001). For once a day intake of nitrate, the dose rates of 40 and 50 grams per day showed a greater increase in mean methaemoglobin values than for the 0 and 30 grams of nitrate per day.

Hitchhikers Guide to the Galaxy on Carbon monoxide
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 ...

Carbon monoxide - WikipediaCarbon monoxide - Wikipedia
Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries.[28] Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the bodys hemoglobin to convert to carboxyhemoglobin.[29] A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.[30]. The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, ...

Part LP21418-6 DetailsPart LP21418-6 Details
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 ...

The study by Branden E. Yee, M.D. and his group presented at the American Society of Anesthesiologists annual meeting that concludes Oct. 22, 2008, measured levels of carboxyhemoglobin, which is formed when carbon monoxide binds to the blood, in 200 children between the ages of 1 and 12. Carbon monoxide binds to blood 200 times more easily than oxygen, but the resultant carboxyhemoglobin is unable to deliver oxygen to body tissue, including that of the brain, heart and muscle.

The study by Branden E. Yee, M.D. and his group presented at the American Society of Anesthesiologists annual meeting that concludes Oct. 22, 2008, measured levels of carboxyhemoglobin, which is formed when carbon monoxide binds to the blood, in 200 children between the ages of 1 and 12. Carbon monoxide binds to blood 200 times more easily than oxygen, but the resultant carboxyhemoglobin is unable to deliver oxygen to body tissue, including that of the brain, heart and muscle. The study provides evidence that the carbon monoxide levels of children exposed to second-hand smoke are often similar to that of active adult smokers and frequently higher than levels in adults exposed to second-hand smoke.

Seventeen cases of acute carbon-monoxide poisoning were treated with therapeutic red cell-exchange. Glasgow Coma Scale score was used to evaluate the level of consciousness. The mean carboxyhemoglobin level decreased from 0.286 +/- 0.1805 (28.6 +/- 18.05%) to 0.0613 +/- 0.0418 (6.13 +/- 4.18%) and Glasgow Coma Scale score increased from 10 +/- 3 to 13.76 +/- 1.89. While 11 patients scored 15 at the end of the treatment, four scored 15 in an hour after the treatment. None of the patients died. Two victims (11.7%) experienced ischemic encephalopathy. Therapeutic red cell-exchange therapy can be an effective treatment in reducing mortality and morbidity in carbon-monoxide poisoning. (C) 2010 Elsevier Ltd. All rights reserved. ...

1. We have compared rebreathing, breath-hold and mean alveolar methods of measuring alveolar carbon monoxide (CO), at levels similar to those found in smokers, as a preliminary to using them as indirect measures of carboxyhaemoglobin levels. In the present study alveolar CO levels were raised by rebreathing a 2% CO mixture.. 2. Breath-hold CO was measured after breath-hold times of 0-35 s in 5 s increments. Using generalized linear models, the maximum value for breath-hold CO was estimated to occur at 23 s. Breath-hold CO after a 20 and 25 s breath-hold were similar to and significantly greater than those of less than 20 s or greater than 25 s.. 3. As expired CO increased, the difference between breath-hold and mean alveolar CO became proportionally larger. On average, breath-hold CO was 24% larger than mean alveolar CO.. 4. Rebreathing, breath-hold and mean alveolar CO were compared at four different inspired oxygen concentrations. Expired CO increased significantly with increasing oxygen for ...

The importance of tar and nicotine in determining cigarette smoking habits. | Journal of Epidemiology & Community HealthThe importance of tar and nicotine in determining cigarette smoking habits. | Journal of Epidemiology & Community Health
Cigarette consumption and inhaling, assessed using carboxyhaemoglobin levels, were studied in 1786 men to investigate the importance of tar and nicotine as determinants of smoking habits. No prior warning was given that smoking habits would be studied. Neither nicotine nor tar yields materially influenced the number of cigarettes smoked a day. Both nicotine and tar yields were negatively associated with inhaling (p less than 0.001) but after allowing for either of the two yields the effect of the other on inhaling was no longer statistically significant. There was, therefore, no indication as to whether nicotine or tar was the more important determinant of smoking habit. ...

Hemoglobin
Literature References: Hb; ferrohemoglobin. The major component of red blood cells which transports oxygen from the lungs to body tissues and facilitates the return transport of carbon dioxide. Mammalian hemoglobins have mol wts of about 64,500. Composed of four peptide chains called globins, each of which is bound to a heme, q.q.v. Normal human hemoglobin is composed of a pair of two identical chains. Iron is coordinated to four pyrrole nitrogens of protoporphyrin IX, and to an imidazole nitrogen of a histidine residue from the globin side of the porphyrin. The sixth coordination position is available for binding with oxygen and other small molecules. Called oxyhemoglobin, HbO2, in the oxygenated form and carboxyhemoglobin, HbCO, when oxygen is displaced by carbon monoxide. Binds reversibly with oxygen while the heme iron remains in the ferrous state. Autoxidation is prevented by the cover of hydrophobic groups of the globin. When the iron in hemoglobin is oxidized from the ferrous to the ...

Test Helps Doctors Determine Patients Smoking Status | EmaxHealth
When I was searching for a science project, I realized that the question of how much carboxyhemoglobin is needed to suggest smoking seemed unanswered, said coauthor and son Ashray Reddy. I thought that by trying to answer this question, I could help people quit smoking.. Researchers used the pulse cooximeter, a device that is clipped to the patients finger and reads the percentages of poisoned blood through a light that is shined through the nail bed. A total of 476 patients who visited the clinic participated. Patients were identified as a smoker, based on a combination of their questionnaire responses and if theyre CO levels exceeded 6% of their blood. Researchers were also able to identify secondhand smokers based on slight changes found in their levels, as well. Results showed that 98 patients were smokers, 72 were secondhand smokers, and 306 were nonsmokers.. For the first time, the entire smoking cessation story can be quickly and noninvasively played out from beginning to ...

I also find drinks like an ice cold 7up as having the same clearing effect as James glass of ice water. Perhaps, the most effective measure of preventing sickness for someone just learning how to smoke a cigar is sugar-loading. Of course, this wont do if you have sugar-averse health conditions (like diabetes mellitus), but sugar is an antidote to nicotine overdose. In fact, if you try to oberve the old cigar smokers in the Caribbean, they carry cigar cubes with them and just pop one as soon as they start to feel a bit queasy from cigar smoking. You can ingest raw sugar when you feel like getting sick or, if youre not comfortable with the idea, just sweeten your espresso a notch higher or have a sugary drink while you smoke.. Over time, as you mature from a beginner learning how to smoke a cigar to a veteran cigar smoker, youll also observe that you have progressively developed a high level of tolerance to nicotine.

Jungbluth and colleagues (22) generated monoclonal antibody 806 [mAb806(IgG2b)] by immunizing mice with murine NR6 fibroblasts expressing human EGFRvIII but not wtEGFR. Characterization of mAb806 confirmed binding to EGFRvIII, but, unexpectedly, mAb806 also bound to tumor cells overexpressing wtEGFR at a level in excess of 1 × 106 receptors per cell (23-26). In vivo studies confirmed that mAb806 bound to and reproducibly inhibited xenograft tumors that expressed EGFRvIII or overexpressed wtEGFR (19, 27-30). Of interest, no mAb806 binding was detected in normal tissues such as the liver (22).. The mechanism of mAb806′s tumor specificity was elucidated with the discovery that the epitope is located between amino acids 287 and 302 in the CR1 domain of the EGFR ECD (31, 32). This epitope is masked in the inactive monomer state (Fig. 1A) or the fully liganded back-to-back dimer state (Fig. 1B), which explains the lack of mAb806 binding to normal tissues in which EGFR is quiescent. However, the ...

Elevated carboxyhemoglobin in a marine mammal, the northern elephant seal | Scripps Institution of Oceanography, UC San DiegoElevated carboxyhemoglobin in a marine mammal, the northern elephant seal | Scripps Institution of Oceanography, UC San Diego
Low concentrations of endogenous carbon monoxide (CO), generated primarily through degradation of heme from hemeproteins, have been shown to maintain physiological function of organs and to exert cytoprotective effects. However, high concentrations of carboxyhemoglobin (COHb), formed by CO binding to hemoglobin, potentially prevent adequate O-2 delivery to tissues by lowering arterial O-2 content. Elevated heme-protein concentrations, as found in marine mammals, are likely associated with greater heme degradation, more endogenous CO production and, consequently, elevated COHb concentrations. Therefore, we measured COHb in elephant seals, a species with large blood volumes and elevated hemoglobin and myoglobin concentrations. The levels of COHb were positively related to the total hemoglobin concentration. The maximum COHb value was 10.4% of total hemoglobin concentration. The mean (+/- s.e.m.) value in adult seals was 8.7 +/- 0.3% (N=6), while juveniles and pups (with lower heme-protein ...

Carbon Monoxide Poisonings Resulting from Open Air Exposures to Operating Motorboats --- Lake Havasu City, Arizona, 2003Carbon Monoxide Poisonings Resulting from Open Air Exposures to Operating Motorboats --- Lake Havasu City, Arizona, 2003
The surveys described in this report document excessive CO exposures in employees and excessive and fatal CO exposures in vacationers amid large numbers of boats. 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 ...

Carbon Monoxide - The Silent Killer - Fireboy-XintexCarbon Monoxide - The Silent Killer - Fireboy-Xintex
Carbon monoxide (CO) is generated wherever combustion occurs, including the operation of gasoline engines, as well as heating and cooking appliances. It is invisible, odorless, tasteless, and deadly. Faulty venting or even a wind shift can create a dangerous situation, particularly in confined areas like boat cabins. Typical symptoms of CO exposure can be mistaken for the flu or seasickness, making accurate on board CO detection a necessity.. The CO Alarm uses a microprocessor to measure and accumulate CO levels. Using the principle of Time Weighted Averaging (TWA), the CO Alarm monitors CO concentration, temperature, and time to calculate levels of Carboxyhemoglobin (COHb). COHb is the degree to which the oxygen carrying capacity of the blood is impeded by the union of carbon monoxide to the hemoglobin and is expressed as a percentage. In simpler terms, our bodies prefer absorbing CO to oxygen, and COHb is the ratio of absorbed carbon monoxide to oxygen in the bloodstream. The CO Alarm ...

There is no effective drug for the therapy of acute carbon monoxide (CO) poisoning. The purpose of the present study was to investigate the potential preventive and therapeutic effects of hemin on an animal model of acute CO poisoning and to provide a potential therapeutic candidate drug. A total of 80 Kunming mice were randomly divided into four groups, namely the air control, acute CO poisoning, hemin-treatment + CO and hemin-pretreatment + CO groups (n=20 each). Furthermore, the mortality rate of mice, blood carboxyhaemoglobin (HbCO) concentration and serum malondialdehyde (MDA) concentration were measured, and pathological changes of the hippocampal area were determined using histochemical staining ...

HBOT speeds the removal of CO from the body. In a study using volunteer subjects, the average time necessary to reduce blood CO levels by half, (written as T1/2, where T is time) was 320 minutes (range of 128 - 409 minutes).2 When exposed to HBOT at 3 atmospheres absolute (ATA), the T1/2 decreases to approximately 23 minutes.3 HBOT also inhibits the tissue destructive inflammatory processes instigated by CO, which can persist after CO levels drop to within normal limits. It is for this reason that measurement of CO blood concentration (abbreviated COHb - carboxyhemoglobin) alone is not the sole determinant of whether HBOT is used or a reliable measurement of poisoning severity. COHb will naturally decline with time, but tissue damage may persist after CO blood levels have declined to normal or expected levels. In cases of prolonged subacute exposure which can include warehouses, parking garages, auto shops etc.), COHb may never reach severe levels but may still produce signs of toxicity. ...

MULTI-COMPONENT SPECTROPHOTOMETRIC DETERMINTION OF INACTIVE AND ACTIVE HEMOGLOBINS IN CANINE AND BOVINE BLOODMULTI-COMPONENT SPECTROPHOTOMETRIC DETERMINTION OF INACTIVE AND ACTIVE HEMOGLOBINS IN CANINE AND BOVINE BLOOD
Cairo Police Equestrian Department, Cairo, Egypt. Abstract. The fractions and concentrations of the inactive Hb pigments (such as sulfhemoglobin, SHb, methemoglobin, MetHb, carboxyhemoglobin, HbCO) and the active Hb (in the oxyhemoglobin form) as well as the total blood Hb concentration were determined in canine and bovine blood, using newly developed multi-component spectrophotometric methods. The results obtained by the cows method revealed values of MetHb% up to 4.607% and of HbCO% up to 4.814%, which are relatively higher than those values in canine blood (up to 1.385% and 3.0%, respectively). These high values of MetHb% and HbCO% in bovine blood may account for the observed decrease in the oxygen-carrying capacity of bovine blood Hb (HbO2%), when compared to canine blood. Furthermore, these methods has yielded values of the cows total blood Hb concentration up to 16.161 g dL-1 which are relatively lower than those values of dogs (up to 19.992 g dL-1). Moreover, these methods has yielded ...

Five-coordinate H64Q neuroglobin as a ligand-trap antidote for carbon monoxide poisoning | Science Translational MedicineFive-coordinate H64Q neuroglobin as a ligand-trap antidote for carbon monoxide poisoning | Science Translational Medicine
Carbon monoxide (CO) is a leading cause of poisoning deaths worldwide, with no available antidotal therapy. We introduce a potential treatment paradigm for CO poisoning, based on near-irreversible binding of CO by an engineered human neuroglobin (Ngb). Ngb is a six-coordinate hemoprotein, with the heme iron coordinated by two histidine residues. We mutated the distal histidine to glutamine (H64Q) and substituted three surface cysteines with less reactive amino acids to form a five-coordinate heme protein (Ngb-H64Q-CCC). This molecule exhibited an unusually high affinity for gaseous ligands, with a P50 (partial pressure of O2 at which hemoglobin is half-saturated) value for oxygen of 0.015 mmHg. Ngb-H64Q-CCC bound CO about 500 times more strongly than did hemoglobin. Incubation of Ngb-H64Q-CCC with 100% CO-saturated hemoglobin, either cell-free or encapsulated in human red blood cells, reduced the half-life of carboxyhemoglobin to 0.11 and 0.41 min, respectively, from ≥200 min when the ...

Berkeley couples mysterious deaths raise public health fears - San Francisco ChronicleBerkeley couples mysterious deaths raise public health fears - San Francisco Chronicle
Medical examiners concluded that the noxious gas accidentally caused the deaths of Roger Hanna Morash, 35, and Valerie Morash, 32, after finding high levels of carboxyhemoglobin in their blood. When Roger Hanna Morashs co-worker came to the two-story apartment on the afternoon of Jan. 23 - he worked from home as a video game developer - she unlocked the apartment door to find him and a cat motionless on the floor upstairs. First responders found another cat and the body of Valerie Morash in the second-floor bedroom. All the usual suspects - heaters, stovetops, the cars in the driveway - were devoid of dangerous levels of carbon monoxide, later inspections revealed. A laser cutter and 3-D printer, which were in the office next to the couples bedroom, were dismissed as likely sources because the printer wasnt powered on and the laser cutter was plugged in to a power strip that was switched off, Bracamontes said.

Inhalation Study For Cigarette-Smoke-Related Lung Tumorigenicity In A/J Mice | PMI ScienceInhalation Study For Cigarette-Smoke-Related Lung Tumorigenicity In A/J Mice | PMI Science
Cigarette smoking is a major cause of lung cancer; however, it has been difficult to reproduce the tumorigenicity of cigarette smoke in preclinical animal models. Increased lung tumorigenicity has been reported in A/J mice exposed for 5 months to an environmental tobacco smoke surrogate or to cigarette mainstream smoke (MS) followed by 4 months without further exposure. Here, we report on MS-induced lung tumor formation in male a/j mice after 18 months of exposure to a continuous flow of MS (6 H/day, 5 D/wk) at total particulate matter concentrations of 150 and 300 mg/m(3). Animal health, housing conditions, test atmosphere characterization, and markers for MS exposure (e.g., carboxyhemoglobin) were carefully monitored over the 18-month period to ensure the stability of the experimental conditions. Body weight gain was reduced dose-dependently in MS-exposed groups. An influx of neutrophils (up to 33% of leukocytes) and lymphocytes (up to 21%) into the bronchoalveolar space, indicating severe ...

Marijuana and Coronary Heart Disease - American College of CardiologyMarijuana and Coronary Heart Disease - American College of Cardiology
In patients with chronic stable angina, smoking a single marijuana cigarette decreased exercise time to angina by 48%. It is postulated that that marijuana-induced sympathetic stimulation increases myocardial oxygen demand. This, along with a decreased oxygen supply due to carboxyhemoglobin formation from inhalation of products of combustion in the marijuana cigarette, decreases the exercise capacity.19. To determine the role of marijuana as a trigger for acute coronary syndrome (ACS), Mittelman et al. performed a case-crossover analysis on 3,882 patients from Onset (Determinants of Myocardial Infarction Onset Study). Among 3,882 patients, 124 reported marijuana use in the past year. The authors found an elevated risk up to 4.8 times for MI within 1 hour of use of marijuana. The risk declined rapidly after 1 hour. It should be noted that the number of patients who reported marijuana use constituted only 3.2% of the entire group. A calculated annual risk of 1.5-3% of acute cardiovascular event ...

Each year, Habanos SA, the company in Cuba responsible of marketing and distributing Habanos worldwide, release a number of exceptional cigars known as Ediciones Limitadas or Limited Editions.. The characteristics of Limited Editions are that they are made by the most celebrated houses in Havana, in rare sizes, using dark coloured wrapper leaves and extra aged tobacco. Since 2000, when the first series of four Limited Editions was unveiled , a further three to five releases have been made annually with the year of release identified on a second band on the cigar.. The exact quantity made of each release is not declared because the Cuban industry cannot tell how many cigars of each size it will be able to make until the bales of specially aged wrapper leaves are opened and graded for quality and colour. Up until 2007, only the wrapper leaves were subjected to extra ageing (2yrs), but since then all the leaves used for Limited Editions carry this extra age.. ...

What a find! I was walking around my local shop today and we found a box of Davidoff Zino Platinum Master Edition 2008 corona gordas laying around. Unmarked. No price on them. This is like finding a diamond in a haystack when you were looking for the needle! An amazing find. And this isnt the 2008 Throwback edition - this is the original from 2008. Lets get smoking..... Construction: If someone took the band off of this I would swear this cigar is a Cuban. It has that same look. A tad rustic. Well put together. A slight twist to the wrapper around the foot. No real veins to speak of and no seams in sight. It had been stashed away for so long the cellophane was yellowed to the point that I thought the bands were actually gold....not the pewter gray they usually are.. Pre-light Aroma and Draw: You can smell that trademark Davidoff mustiness from the wrapper and the foot of the cigar. Some mushroom and dry hay mix with that damp cellar around the foot as well.

A stable reference solution for calibrating and monitoring blood gas instrumentation is disclosed. The solution comprises an aqueous mixture containing a hemoglobin solution derived from a mammalian source which comprises at least about 95% reduced hemoglobin. The solution additionally contains a bicarbonate buffer and a metal catalyzed methemoglobin reducing system and an organic buffer. To provide a control element having a variety of properties similar to fresh, whole, human blood, the reference solution is stored in a sealed ampule under an inert atmosphere containing CO2 until just prior to use. The ampule is subsequently opened and the solution is equilibrated with a gas mixture having components which provide gasses in a physiological range to the solution. The solution is characterized by exhibiting properties similar to fresh blood subsequent to equilibration and an extended storage life prior to equilibration.

Because carbon monoxide (CO) is a colorless and odorless gas, symptoms of CO poisoning are difficult to recognize, making CO a hidden killer in home environments. To prevent CO poisoning, we used artificial intelligence and Internet of Things (IoT) technology to develop a CO poisoning prevention system with the following functional features: (1) a CO sensor, which was installed in the bathroom at home and immediately activated to warn the household when the CO concentration was excessively high; (2) an electric window opener and a fan, which when activated performed forced ventilation and thereby reduced CO concentration; (3) a device that cut off the gas supply; (4) a Line application that notified family members and signaled the community management center to conduct emergency rescue operations; and (5) a mechanism for unlocking the door to allow people to enter for emergency rescue. The obtained results may help reduce the number of CO poisoning cases and casualties in the winter in Taiwan ...

We examined the effects on cancer incidence of exclusive cigar and pipe smoking, and in combination with cigarettes, among 102,395 men from Denmark, Germany, Spain, Sweden and the United Kingdom in the EPIC cohort. Hazard ratios (HR) and their 95% confidence intervals (CI) for cancer during a median 9-year follow-up from ages 35 to 70 years were estimated using proportional hazards models. Compared to never smokers, HR of cancers of lung, upper aerodigestive tract and bladder combined was 2.2 (95% CI: 1.3, 3.8) for exclusive cigar smokers (16 cases), 3.0 (2.1, 4.5) for exclusive pipe smokers (33 cases) and 5.3 (4.4, 6.4) for exclusive cigarette smokers (1,069 cases).

How Heart Disease May Have Led to James Gandolfinis Death | Medicine HunterHow Heart Disease May Have Led to James Gandolfinis Death | Medicine Hunter
James Gandolfini, the larger-than-life Emmy award-winning actor who played mob boss Tony Soprano, has met his end in Rome, due to an apparent heart attack. At age 51, his passing was entirely premature. As Tony Soprano, Gandolfini insinuated himself into popular culture as the big, menacing, complex and implacable mobster who ruled his criminal empire with old-school, strong-arm tactics. But every tough guy knows that theres someone - or something - tougher out there. For Tony Soprano, the hit man was likely heart disease.. The much-beloved Gandolfini was by all accounts a marvelous friend and deeply respected by his peers. He had a charismatic personality and a great sense of humor. He was also very overweight, a cigar smoker and a man known to remain at the dinner table until the last strands of pasta and crumbs of tiramisu had been taken care of. As Tony Soprano, he could menace just about anybody. But as actor Gandolfini, his lifestyle vulnerabilities made him an easy target for a highly ...
