Background: Mixed venous oxygen saturation (SVO2), a direct marker of circulatory adequacy measured in the pulmonary artery, has been proposed as a more immediate reflection of perfusion compared to ...
The mixed venous-to-arterial carbon dioxide (CO2) tension difference [P (v-a) CO2] is the difference between carbon dioxide tension (PCO2) in mixed venous blood (sampled from a pulmonary artery ...
