What method(s) is/are used to measure oxygen consumption?
I.Fick method
II.analysis of inspired and expired gases
III. $\dot { V } / \dot { Q }$ scans

Question

Quizplus · Accepted Answer

I and II are correct. The Fick method involves measuring cardiac output and the difference in oxygen content between arterial and venous blood to calculate oxygen consumption. Analysis of inspired and expired gases directly measures the amount of oxygen consumed by comparing the oxygen content of inhaled and exhaled air. $\dot { V } / \dot { Q }$ scans are used to assess ventilation/perfusion in the lungs, not directly to measure oxygen consumption.
