TY - JOUR. T1 - Alveolar dead space as a predictor of severity of pulmonary embolism. AU - Kline, Jeffrey A.. AU - Kubin, Anita K.. AU - Patel, Manish M.. AU - Easton, Edward J.. AU - Seupal, Rawle A.. PY - 2000/6. Y1 - 2000/6. N2 - Objective: To determine whether the alveolar dead space volume (V(D)alv), expressed as a percentage of the alveolar tidal volume (V(D)alv/V(T)alv), can predict the degree of vascular occlusion caused by pulmonary embolism (PE). Methods: Fifty-three subjects with suspected PE were prospectively studied. Pulmonary embolism was diagnosed in 33 by high- probability ventilation/perfusion (V/Q) scan (n = 19) or by pulmonary arteriography (PAG, n = 14). Pulmonary embolism was excluded by PAG in 20 subjects. The V(D)alv/V(T)alv was determined from volumetric capnography and arterial blood gas analysis, which permits measurement of the physiologic dead space, V(D)phys (mL) = [(PaCO2 - PeCO2)/PaCO2] · tidal volume. Airway dead space (V(D)aw) was subtracted to yield the ...

Her early clinical research focused on the use of bedside technology, including capnography, portable spirometry and bedside ultrasonography to improve the accuracy of patient care in the emergency department. She then began honing in on capnography, assessing its use to monitor ventilation in patients with acute asthma exacerbations, altered mental status, procedural sedation and endotracheal intubation, as well as assessing the utilization of capnography in different patient care areas. Melissas focus is now on translational research, and improving the dissemination and implementation of research into practice. She has explored the barriers and facilitators to the implementation of technology into acute care settings. Dr. Langhan has now incorporated this data into the development of a pilot study to improve use of these capnography in the emergency department for critically ill patients. Her overarching goal is to reduce adverse events and improve quality of care among this vulnerable ...

Physiological Dead Space ( Total Dead Space ) = Conducting airways (Anatomic Dead Space) + Pulmonary capillaries (Alveolar Dead Space).

This study introduces a new equal area method for the calculation, representation, and visualization of physiologic dead space based on a principle similar to the Fowler equal area method. The new method is analytically identical to the Bohr-Enghoff equation and yields numerical results that do not differ significantly from those calculated directly by the Bohr-Enghoff equation. Advantages of this new method include the following: (1) the graphical representation on a linear scale of the relations between all of the dead space volumes and fractions, including Vdanat, Vdalv, Vdphys, Vt, Vdanat/Vt, Vdalv/Vt, Vdphys/Vt, and Vdalv/Vtalv, which is especially helpful for the visualization of dead spaces during bedside monitoring of patients; (2) the use of a principle similar to that used in the Fowler equal area method, which makes the calculation of anatomical and physiologic dead spaces on the carbon dioxide expirogram consistent; (3) the use of a more straightforward method than the partitioning ...

The subjects wore a nasal mask (Respironics Inc, Murrayville, Pennsylvania, USA) connected to a heated pneumotachometer (Hans Rudolph Inc, Kansas City, Missouri, USA) and a differential pressure transducer (Validyne Corp, Northbridge, California, USA) calibrated with a rotameter for measurement of airflow. Inspiratory (Ti) and expiratory (Te) times were determined from this signal and it was electronically integrated for calculation of tidal volume (Vt). Minute ventilation (VE) was calculated as the sum of all Vt per minute. The duty cycle (Ti/Ttot) was also calculated for each breath. End-tidal carbon dioxide tension (Petco2) was measured from expired air within the nostril using a calibrated infrared CO2 analyser (Capnograph/Oximeter Monitor, BCI, Waukesha, Wisconsin, USA) while arterial oxygen saturation (Sao2) was measured using a pulse oximeter probe attached to the index finger (Capnograph/Oximeter Monitor). Pressure was monitored in the mask with an open catheter attached to a pressure ...

St. Josephs/Candler Hospitals reduced opioid-related events with patient-controlled analgesia (PCA) pumps. The hospitals are error-free since using smart PCA pumps with integrated capnography.. by Michael Wong, JD (Executive Director, Physician-Patient Alliance for Health & Safety). St. Josephs/Candler Hospitals (SJ/C) in Savannah, Georgia, are two of the oldest continuously operating hospitals in the US. About 10 years ago, SJ/C had three opioid-related events with patient-controlled analgesia (PCA) with serious outcomes over a two-year period.. Fortunately, none of these adverse events resulted in deaths, says Carolyn Williams, RPh, Medication Safety Specialist at SJ/C.. Since using smart PCA pumps with integrated capnography, SJ/C has been error-free. Read More →. ...

I had an 80 year old woman with a broken hip in extreme pain. She had taken one tramadol, which obviously hadnt touched her. I like to premedicate the patient before I even try to move them so, in increments, I gave her 7mg of Morphine over ten minutes. I waited about five minutes more, and then we packaged her on a scoop stretcher. Out in the ambulance she was still in a fair amount of pain and the roads we were on were pretty bumpy so I called to get permission to give her 3 more mg, and I was pleased the doctor actually told me to go ahead and give her 5 more mg. (We can give up to 0.1 mg/kg on standing order, and have to call for more ...

Metabolic acidosis, a common condition in patients with renal failure, may be linked to protein-energy malnutrition (PEM) and inflammation, together also known as malnutrition-inflammation complex syndrome (MICS). Methods of serum bicarbonate measurement may misrepresent the true bicarbonate level, since the total serum carbon dioxide measurement usually overestimates the serum bicarbonate concentration. Moreover, the air transportation of blood samples to distant laboratories may lead to erroneous readings. In patients with chronic kidney disease (CKD) or end-stage renal disease (ESRD), a significant number of endocrine, musculoskeletal, and metabolic abnormalities are believed to result from acidemia. Metabolic acidosis may be related to PEM and MICS due to an increased protein catabolism, decreased protein synthesis, endocrine abnormalities including insulin resistance, decreased serum leptin level, and inflammation among individuals with renal failure. Evidence suggests that the catabolic ...

PETCO2 has been considered as the sixth basic vital sign in addition to body temperature, respiration, pulse, blood pressure, and arterial oxygen saturation. ASA has stipulated PETCO2 as one of the basic monitoring indicators during anesthesia. In recent years, with the development of sensor analysis, microcomputer and other technologies and multi-disciplinary interpenetration, continuous non-invasive measurement of PETCO2 using monitors has been widely used in clinics. PETCO2 and CO2 curves have special clinical significance for judging lung ventilation and blood flow changes.Therefore, PETCO2 has important application value in clinical anesthesia, cardiopulmonary cerebral resuscitation, PACU, ICU, and pre-hospital first aid.. The portable end-expiratory capnograph can provide the patients PETCO2 value and respiratory rate, and the results are continuously displayed through numerical values ​​and waveforms. The device can quantitatively display the partial pressure of carbon dioxide at the ...

In some patients with PHT who arrest, CPR may be ineffective due to a failure to achieve adequate pulmonary blood flow and ventricular filling. In one study of patients with known chronic PHT who arrested in the ICU, survival rates even for ventricular fibrillation were extremely poor and when measured end tidal carbon dioxide levels were very low. In the same study it was noted that some of the survivors had received an intravenous bolus administration of iloprost, a prostacyclin analogue (and pulmonary vasodilator) during CPR(6).. CPR may therefore be ineffective. Intubation and positive pressure ventilation may also be associated with haemodynamic deterioration in PHT patients(7), and intravenous epinephrine (adrenaline) has variable effects on the pulmonary circulation which could be deleterious(8).. If inhaled nitric oxide (iNO) can improve pulmonary blood flow and reduce right ventricular afterload, it could theoretically be of value in cases of shock or arrest with RV failure, especially ...

After a fasting period of 16 h with free access to water, the pigs were anesthetized with 500 mg ketamine followed by 15 mg midazolam, given intramuscularly. Pigs were weighed, and an ear vein was cannulated to allow infusions of pentobarbital (2 mg · kg−1· h−1). Fentanyl bolus doses were given if needed (2-4 μg/kg). The trachea was intubated, and the lungs were artificially ventilated with an air-oxygen mixture, using a Cameco UV 705 respirator (Cameco, Sweden), with a frequency of 19 breaths/min, and 20 cm water pressure. The end-tidal carbon dioxide level was maintained between 4 and 5 kPa (Godart Capnograph Mark 11; E. Jaeger, Wuerzburg, Germany). Heart rate and blood pressure were measured continuously (Pressure Transducer, HP 78342A; Hewlett Packard, Boeblingen, Germany). Rectal temperature was measured continuously, and the temperature of the pig was maintained at 38°C with a heating blanket. The jugular vein was cannulated for infusion of fluids (2.5% glucose in 0.45% saline) and ...

Assessment of the oxygen and carbon dioxide content of expired air during exercise is critical for determining cardiorespiratory status. The purpose of this study was to compare the new portable metabolic analyzer PNOE with COSMED - Quark CPET, a previously validated stationary metabolic cart.Methods: A total of 22 subjects (17 male and 5 female) aged 32.3 ± 11.1 years took part in the study. Breath by breath gas exchange was measured by both devices during a four-stage incremental protocol on a cycle ergometer. On a separate day, 10 participants repeated the trial to assess the reliability of the PNOE metabolic cart.Results: Strong correlations were obtained in VO2 (r = 0.98, p 2 (r = 0.98, p r = 0.98, p r = 0.91, p 2 and VCO2 analysis, respectively. There were no significant differences in VO2, VCO2, VE, or RQ between the two devices. Intraclass correlation coefficient was high between the two trials for VO2 (r = 0.98, p 2 (r = 0.98, p r = 0.99, p r = 0.93, p Conclusions: Our data indicate that the

We hypothesize that capnography could detect hypoventilation during induction of bronchoscopic sedation and starting bronchoscopy following hypoventilation, may decrease hypoxemia. Patients were randomized to: starting bronchoscopy when hypoventilation (hypopnea, two successive breaths of at least 50% reduction of the peak wave compared to baseline or apnea, no wave for 10 seconds) (Study group, n = 55), or when the Observer Assessment of Alertness and Sedation scale (OAAS) was less than 4 (Control group, n = 59). Propofol infusion was titrated to maintain stable vital signs and sedative levels. The hypoventilation during induction in the control group and the sedative outcome were recorded. The patient characteristics and procedures performed were similar. Hypoventilation was observed in 74.6% of the patients before achieving OAAS < 4 in the control group. Apnea occurred more than hypopnea (p < 0.0001). Hypoventilation preceded OAAS < 4 by 96.5 ± 88.1 seconds. In the study group, the induction ...

Background Existing evidence concerning the management of traumatic brain injury (TBI) patients underlines the importance of right treatment strategies in both prehospital and early in-hospital care and attention. of 408 individuals were analyzed. Based on this, a set of recommendations expected to improve results was developed by the study group and implemented in participating centers. Recommendations included time factors (transport to appropriate trauma center, staying away from secondary transfer), sufficient treatment strategies (prehospital liquid and airway administration, anesthesia, venting), HMOX1 monitoring (pulse oximetry and blood circulation pressure monitoring in every sufferers, capnography in ventilated sufferers) for prehospital treatment. In the crisis department concentrate was on initial CT scan at the earliest opportunity, brief interval between CT surgery and scan and early usage of thrombelastometry to optimize coagulation. Following execution of these suggestions, data ...

The purpose of this study is to assess the utility of the ExSpiron Respiratory Variation Monitor in patients undergoing an interventional procedure with anesthesia. The primary outcome measure will be the average minute ventilation of the patient during the procedure. This study will also examine the correlation between clinical interventions such as drug administrations or airway maneuvers with data from the monitor. Additionally the study may provide information about the ability of this new monitoring system to prevent hypoxemia during these procedures and to consider its utility, compared with capnography, to detect hypopnea.. Background Assessing the adequacy of ventilation during Monitored Anesthesia Care (MAC) and sedation is difficult. Agents used to provide procedural sedation can depress ventilatory drive and can interfere with airway patency, making it much more likely that the patient will hypoventilate and experience partial or complete obstruction to ventilation. [It is actually ...

Capnography should be used in all intubated children and infants for early detection of mal- or displacement of the tracheal tube.. In children and infants with shock, use a 10 mL kg-1 fluid bolus. There is an emphasis on smaller bolus volume with careful re-assessment after each bolus to enable early identification of signs and symptoms of fluid overload (hepatomegaly, bilateral basal lung crackles, and jugular venous distention). Use balanced isotonic crystalloids as first choice of fluid bolus, if available. If not, normal saline (0.9%) is an acceptable alternative. In haemorrhagic shock, keep crystalloid boluses to a minimum (max 20 mL kg-1). Consider early blood products in children and infants with severe trauma and circulatory failure, using a strategy that focuses on improving coagulation.. Children and infants with a febrile illness and no signs of shock should not receive fluid bolus therapy. In children and infants with persistent decompensated circulatory failure after multiple fluid ...

Back to reality, our time in the ORs at the two hospitals in Kigali and one in Butare have been interesting, challenging, frustrating, and of course fun. We continue to be involved in cases that are far more complicated than many we see at home, including unusual medical conditions and advanced airway obstructions. The personnel do manage well, despite the limitations in equipment. Thoracotomies, craniotomies are just done, all without art lines or capnography. In neither of the two university hospitals in the two cities have we been able to obtain electrolytes on any patients, due to equipment problems. On our two day trip to Butare, the main university town two hours south of Kigali, I delivered the surplus Spacelabs monitor kindly donated by the biomed people in Kingston (that I have been carrying half way around the world). This was much appreciated, as the monitors and machines in Butare are quite old and in varied states of repair. Its first use was during a laparotomy for a huge ...

BACKGROUND: Acute pain is a common condition among prehospital patients and prompt management is pivotal. Opioids are the most frequently analgesics used in the prehospital setting. However, opioids are highly addictive, and some patients may develop opioid dependence, even when they are exposed to brief opioid treatments. Therefore, alternative non-opioid analgesia should be developed to manage pain in the prehospital setting. Used at subdissociative doses, ketamine, a noncompetitive N-methyl-D-aspartate and glutamate receptor antagonist, provides analgesic effects accompanied by preservation of protective airway reflexes. In this context, we will carry out a randomized controlled, open-label, multicenter trial to compare a subdissociative dose of ketamine to morphine to provide pain relief in the prehospital setting, in patients with traumatic and non-traumatic pain.. METHODS/DESIGN: This will be a multicenter, single-blind, randomized controlled trial. Consecutive adults will be enrolled in ...

Results There were 106 patients with a diagnosis of obstructive or cardiac causes of dyspnoea that had prehospital ETCO2 levels measured during the study period. ETCO2 was significantly lower in patients diagnosed with CHF (31 mm Hg 95% CI 27 to 35) versus obstructive pulmonary disease (39 mm Hg 95% CI 35 to 42; p,0.001). Lower ETCO2 levels predicted CHF, with an area under the Receiver Operating Characteristics Curve of 0.70 (95% CI 0.60 to 0.81). Using ETCO2 ,40 mm Hg as a cut-off, the sensitivity for predicting heart failure was 93% (95% CI 88% to 98%), the specificity was 43% (95% CI 33% to 52%), the positive predictive value was 38% (95% CI 29% to 48%), and the negative predictive value was 94% (95% CI 89% to 99%).. ...

Mizumura, K.; Sato, J.; Kumazawa, T., 1986: Continuous recording of arterial pressure and carbon dioxide partial pressure and pressure carbon dioxide partial pressure and ph of the cerebrospinal fluid during acute exposure to low oxygen and high carbon dioxide partial pressure environment in dogs

SOURCE: Grist. DATE: March 6, 2019. SNIP: Our planets level of carbon dioxide in the atmosphere reached a new, jarring record last month. Scientists from Scripps Institution of Oceanography announced on Tuesday that Februarys average carbon dioxide measurement was 411.66 parts per million as measured in Mauna Loa, Hawaii.. Since humanitys greenhouse gas emissions were at an all-time high last year, a new record was expected. What was shocking was that it occurred so early in the year: Earths carbon dioxide levels typically peak in May, when the vast northern forests of North America and Asia are just beginning to green up ...

Several factors contribute to overall gas exchange in the lungs. Each breath (tidal volume) is composed of functional movement of air in and out of the alveolus and nonfunctional movement of air through bronchioles, bronchi, trachea, and nonperfused areas of lung (physiologic dead space). The physiologic dead space is approximately 30% of the tidal volume. The air remaining in the chest at the end of exhalation is referred to as the functional residual capacity. Dead space and the functional residual capacity do not contribute to gas exchange. The amount of air inhaled and exhaled in a minute is referred to as minute ventilation and is the product of the respiratory rate and tidal volume. Relatively small changes in the functional alveolar space demand large increases in the minute ventilation to maintain the same rate of gas exchange. Either raising the fraction of inspired oxygen (Fio2) or increasing the surface area or functional residual capacity of the lung can increase total alveolar ...

TY - PAT. T1 - Identification of dynamic hyperinflation using a combination of expiratory flow and respiratory carbon dioxide signals.. AU - Rees, Stephen E.. AU - Larraza, S. AU - Karbing, Dan S.. PY - 2017/1/5. Y1 - 2017/1/5. N2 - The present invention relates to a method for identification of an increase in the gas volume of the lung caused by the inability of a patient to expire completely, known as dynamic hyperinflation or gas trapping. The method applies analysis of a patient´s pattern of expiratory flow, along with the pattern of respiratory, e.g. expiratory, carbon dioxide level, for example the capnography signal. Analysis of these signals enables identification of dynamic hyperventilation, along with identification of change in the degree of dynamic hyperinflation indicating improvement or worsening in the patient state.. AB - The present invention relates to a method for identification of an increase in the gas volume of the lung caused by the inability of a patient to expire ...

The management of patients suspected of having botulism consists of both supportive measures and antitoxin administration. Management is also complicated by the absence of a timely diagnostic biological marker to confirm the diagnosis and the time sensitive nature of treatment implementation to prevent further progression of illness.. In general, patients should be admitted to an appropriate area of the hospital for continuous monitoring of respiratory and neurological function. There is a risk of progressive muscle weakness and subsequent respiratory failure. Objective measures such as negative inspiratory force, pulse oximetry, and end-tidal capnography are often used to determine need for intubation and ventilator support.. Activated charcoal is generally administered to patients, if no contraindications exist. In vitro studies show that it absorbs serotype toxin A and it is suggested even after a substantial time delay as the bacteria and spores may still be present in the gastrointestinal ...

When caring for ventilator-dependent patients, reliable oxygenation and ventilation monitoring are vital to providing high-quality care and improving patient safety in post-acute care settings. Many long-term acute care facilities are faced with low clinician-to-patient ratios and alarm fatigue, while needing to administer many different active therapies, wean patients off ventilation, and chart patient data. In sub-acute care facilities, where workflows may not be as strained, ventilator-dependent patients still require continuous monitoring to recognize changes in status. Masimos industry-leading SET® pulse oximetry, integrated capnography, and supplemental remote monitoring solutions help clinicians continuously monitor ventilated patients and improve workflows.

We coined the term relative [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] to indicate a quantitative value used to compare the relative oxygen delivery rates of the tested POCs. We do not have data to state how this relative [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] compares to actual [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] in a human. However, the steady-state oxygen reading inside the lung model should be quite close to the [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] for a given breath in a human, as the dilution of the oxygen pulse with room air in a single inspiration by a human should be the same as the steady-state dilution of oxygen delivered by the POC with the minute volume of air pumped by the lung simulator. The only difference would be that in a human the first portion of inspiration, from the anatomic dead space, would contain alveolar gas and thus have a slightly lower oxygen concentration than gas from the simulator that does not consume oxygen. ...

patients are allocated to one of the two study groups.. In both groups a mixture of 60% nitrous oxide and 40% oxygen is administered through a face mask. In the first group the patient receives a constant concentration of sevoflurane. In this group the remifentanil concentration will be injected via an intravenous line in a step up protocol. In the second group remifentanil is injected in a fixed rate and sevoflurane is administered in a step up concentration.. During the study, at predefined times, we will assess different levels of sedation (OAA/S score) and the reaction on tetanic stimulation of the ulnar nerve, insertion of a laryngeal mask airway and laryngoscopy. In addition heart rate, SpO2 and capnography will be recorded continuously and non invasive bloodpressure will be recorded using a 1 minute interval time. Spectral entropy and BIS derived from the frontal EEG will be used to monitor clinical cerebral drug effect.. The null hypothesis is that remifentanil lowers the concentration ...

This piece focuses on procedural sedation and questions regarding, who delivers it, is there a standard for monitoring what is the correct approach to capnography? Further discussion also includes questions regarding sedation; is there room for compromise in the debate surrounding propofol? If so where does responsibility lie for that? Is it wrong to sell this as a general anaesthetic? Is there room for sedation teams who can find a compromise position?.

Lets run through a case example. Bear, is an aptly named healthy 6-year-old 33 kg chocolate Labrador retriever is premedicated with hydromorphone and dexmedetomidine, both IM. After Bear vomited and became sedate, a catheter is placed in his right cephalic vein and he is induced with midazolam and ketamine. He is intubated and placed on 2% isoflurane delivered in a circle system using 2 L/Min oxygen. He is clipped, prepped and received a morphine-saline epidural for his stifle surgery. He is moved and instrumented on the capnograph in the OR. There is no waveform, so his technician gives a breath, makes a nice elephant holding the tail waveform and the ETCO2 is 68 mm Hg. The seasoned staff reaches across and indicates that she should stop, because he wont breath for himself if we keep breathing for him so she stops. Because her employer is wonderful, and the patient is stable and large, she practices her art line skills on the tiny artery under the front paw and uses a point of care ...

Answers to common anesthetic problems. We will discuss a vareity of anesthesia related questions such as how do you trouble shoot hypotension? When do you treat bradycardia? How do you interpret your capnograph?

INTRODUCTION: The use of focused cardiac ultrasound (FoCUS) in a prehospital setting is recommended. Pocket ultrasound devices (PUDs) appear to be well suited to prehospital FoCUS. The main aim of our study was to evaluate the interpretability of echocardiography performed in a prehospital setting using a PUD based on the experience of the emergency physician (EP). METHODS: This was a monocentric prospective observational study. We defined experienced emergency physicians (EEPs) and novice emergency physicians (NEPs) as echocardiographers if they had performed 50 echocardiographies since their initial university training (theoretical training and at least 25 echocardiographies performed with a mentor ...

The data provide preliminary evidence that raising end-tidal pCO(2) by means of capnometry feedback is therapeutically beneficial for panic patients. Replication and extension will be needed to verify this new treatments efficacy and determine its mechanisms.
