In a model of hemorrhagic shock, end-tidal carbon dioxide tension (EtCO2) has been shown to reflect the dependence of oxygen delivery (DO2) and oxygen consumption (VO2) at the onset of shock. The objectives of the present study were to determine whether variations in EtCO2 during volume expansion (VE) are correlated with changes in oxygen extraction (O2ER) and whether EtCO2 has predictive value...

BACKGROUND During cardiac arrest, end-tidal carbon dioxide (ETCO2) monitoring is recommended as a chest compression performance indicator. However, its frequency of use during out-of-hospital cardiac arrest (OHCA) and its benefits have never been evaluated in real clinical situations. OBJECTIVE We investigated OHCA patients in Taiwan to evaluate the frequency of ETCO2 monitoring and its effec...

BACKGROUND End-tidal carbon dioxide (ETCO2) monitoring is an important part of patient care. Understanding and interpreting ETCO2 wavelengths can be a challenge. This pilot study explored the efficacy of a novel approach to educating clinicians on ETCO2 monitoring via game theory. METHOD A video game application for ETCO2 monitoring was developed. Clinicians were encouraged to play the game o...

End-tidal CO2 concentration (ETCO2) may serve as a simple noninvasive measurement of the blood flow generated by precordial compression during cardiopulmonary resuscitation (CPR). In a mechanically ventilated porcine preparation of ventricular fibrillation, onset of fibrillation was associated with a rapid decrease in ETCO2 from 4.0 +/- 0.2% to less than 0.7 +/- 0.2%. With precordial compressio...

This prospective study included 32 patients undergoing cardiopulmonary bypass (CPB) for elective coronary artery bypass grafting correlates the respiratory end-tidal CO2 (ETCO2) during partial separation from CPB with cardiac output (CO) following weaning from CPB. After induction of general anesthesia, a pulmonary artery catheter was inserted for measurement of cardiac output by thermodilution...

BACKGROUND The aim of this study was to determine the usefulness of end tidal carbon dioxide (ETCO2) monitoring in hypotensive shock patients presenting to the ED. METHODS This was a prospective observational study in a tertiary ED. One hundred three adults in shock with hypotension presenting to the ED were recruited into the study. They were grouped according to different types of shock, hy...

BACKGROUND To investigate the correlation and level of agreement between end-tidal carbon dioxide (EtCO2) and blood gas pCO2 in non-intubated children with moderate to severe respiratory distress. METHODS Retrospective study of patients admitted to an intermediate care unit (InCU) at a tertiary care center over a 20-month period with moderate to severe respiratory distress secondary to asthma...

BACKGROUND For early detection of respiratory and hemodynamic changes during anesthesia, continuous end-tidal carbon dioxide concentration (PETCO2) is monitored by capnometry. However, the accuracy of CO2 monitoring during spontaneous breathing in extubated patients remains undetermined. Therefore, we aimed to compare P(ETCO2) measured by capnometry using an oxygen mask with a carbon dioxide sa...

Hyperventilation has been linked to emotional distress in adults. This study investigates end-tidal carbon dioxide (ETCO2 ), respiratory rate (RR), and heart rate variability (HRV) in adolescent girls with emotional disorders and healthy controls. ETCO2 , RR, HRV, and ratings of emotional symptom severity were collected in adolescent female psychiatric patients with emotional disorders (n = 63)...

OBJECTIVE End-tidal carbon dioxide (ETCO2) monitoring has numerous clinical applications in the emergency setting. This study was designed to explore the current availability and utilization patterns for continuous ETCO2 monitoring in pediatric emergency departments. METHODS A Web-based survey was distributed to directors of all accredited pediatric emergency medicine fellowship programs in t...
