Abstract
The veno-arterial difference in PCO2 can be computed after the simultaneous measurment of arterial blood and of mixed venous blood from the distal of a pulmonary artery catheter . Under physiological conditions, dPCO2 ranges from 2 to 5 mmHg. The dPCO2 depends on carbon dioxide and cardiac output by a complex fashion. dPCO2 cannot serve as a marker of tissue hypoxia contrary to what was initially thought. However, dPCO2 can be considered as a marker of the adequacy of venous blood flow to remove the total CO2 produced by the peripheral tissues.Pubblicazioni consigliate
