End tidal carbon dioxide as a predictor of the arterial PCO2 in the emergency department setting.
OBJECTIVES Patients arriving in the emergency department (ED) need rapid and reliable evaluation of their respiratory status. Mainstream end tidal carbon dioxide (ETCO(2)) is one of the methods used for this purpose during general anaesthesia of intubated patients in the operating theatre. Sidestream ETCO(2) (SSETCO(2)) might be a non-invasive, rapid, and reliable predictor of arterial Pco(2) i...
متن کاملDevelopment of atelectasis and arterial to end-tidal PCO2-difference in a porcine model of pneumoperitoneum.
BACKGROUND Intraperitoneal insufflation of carbon dioxide (CO2) may promote collapse of dependent lung regions. The present study was undertaken to study the effects of CO2-pneumoperitoneum (CO2-PP) on atelectasis formation, arterial oxygenation, and arterial to end-tidal PCO2-gradient (Pa-E'(CO2)). METHODS Fifteen anaesthetized pigs [mean body weight 28 (SD 2) kg] were studied. Spiral comput...
متن کاملVariation in the arterial to end-tidal PCO2 difference during one-lung thoracic anaesthesia.
We have measured the arterial to end-tidal PCO2 difference (PaCO2-PE'CO2) in 22 patients undergoing pulmonary resection in the lateral thoracotomy position during two-lung ventilation (TLV) and after transition to one-lung ventilation (OLV). With OLV for each patient, the practice of correcting the estimate by an initial measurement of (PaCO2-PE'CO2) was evaluated by subtracting the initial (Pa...
متن کاملThe accuracy of transcutaneous PCO2 in subjects with severe brain injury: a comparison with end-tidal PCO2.
BACKGROUND In patients suffering from brain injury, end-tidal PCO2 (PETCO2 ) monitoring is controversial, but transcutaneous PCO2 (PtcCO2 ), which is noninvasive and utilizes immediate display, may be an alternative method. We hypothesized that PtcCO2 would be more accurate than PETCO2 for monitoring PaCO2 in patients with severe brain injury. METHODS A prospective observational study include...
متن کاملArterial Pco2 and Cerebral Hemodynamics.
REIVICH, MARTIN. Arterial Pcoz and cerebral hemodynamics. Am. J. Physiol. 206(1) : q-35. rg64.---The effect of arterial Pco:! in the control of cerebral hemodynamics over the full range of responsiveness of the cerebral vasculature was studied in the rhesus monkey. Cerebral perfusion pressure and arterial 02 saturation were controlled so that they produced no significant effect on the cerebral ...
