Quizplus · Accepted Answer

The Fick method is often used to measure O₂ consumption, as it relies on the principle of oxygen diffusion across the alveolar-capillary membrane and subsequent uptake by the tissues. This method involves measuring the difference in oxygen content between arterial and venous blood, as well as determining cardiac output. Analysis of inspired and expired gases can also be used to measure O₂ consumption, by measuring the amount of oxygen consumed and carbon dioxide produced during respiration. However, this method is not as accurate as the Fick method and may be affected by factors such as dead space ventilation. V/Q scans, which involve assessing the distribution of ventilation and perfusion in the lungs, are not usually used to directly measure O₂ consumption.
