What is the interpretation of a decrease in the C(a - $ \bar{V} $ )O₂?

Question

Quizplus · Accepted Answer

Slowly moving blood gives up more oxygen to the tissues because it spends more time in contact with them; this causes the blood leaving the capillaries (now venous blood) to have relatively low oxygen content. The result is a low mixed venous oxygen content and thus an increased difference between arterial and venous oxygen contents $ C(a-\bar{v}) $O2. For this reason, a decrease in C$\bar {v}$O₂or an increase in the $ C(a-\bar{v}) $O2 generally signals a reduction in , assuming the oxygen consumption rate remains constant. In some critically ill patients, this relationship between $ C(a-\bar{v}) $O2 and $ \dot{Q} $ may not be reliable because of abnormalities in blood flow distribution through capillary beds.
