Letters to the Editor Carbon Dioxide Pressure-concentration Relationship in Arterial and Mixed Venous Blood
Sun, Xing-Guo, James E. Hansen, William W. Stringer, Hua Ting, and Karlman Wasserman Carbon dioxide pressure-concentration relationship in arterial and mixed venous blood during exercise. J Appl Physiol 90: 1798–1810, 2001.—To calculate cardiac output by the indirect Fick principle, CO2 concentrations (CCO2) of mixed venous (Cv#CO2) and arterial blood are commonly estimated from PCO2, based on ...
متن کاملVentilatory effects and plasma concentration of morphine in man.
The relationship between the plasma concentration of morphine and morphine-induced changes in ventilation and the ventilatory response to carbon dioxide was studied in 17 healthy adults undergoing elective surgery under general anaesthesia. Each subject was given morphine sulphate 0.15 mg kg-1 i.m.; ventilation (Ve), end-tidal PCO2(PE'CO2), mixed venous PCO2(PVCO2) and ventilatory response to c...

متن کاملUrinary bladder partial carbon dioxide tension during hemorrhagic shock and reperfusion: an observational study
INTRODUCTION Continuous monitoring of bladder partial carbon dioxide tension (PCO2) using fibreoptic sensor technology may represent a useful means by which tissue perfusion may be monitored. In addition, its changes might parallel tonometric gut PCO2. Our hypothesis was that bladder PCO2, measured using saline tonometry, will be similar to ileal PCO2 during ischaemia and reperfusion. METHOD ...
متن کاملAcid base changes in arterial and central venous blood during cardiopulmonary resuscitation.
Twenty-seven patients in cardiopulmonary arrest had simultaneous measurements of arterial and central venous blood gases during cardiopulmonary resuscitation (CPR) with a pneumatic chest comparison and ventilation device. Mean central venous and arterial hydrogen ion concentrations, PCO2 and calculated bicarbonate concentrations were significantly different (P less than 0.01) at all sampling ti...
