Direct Fick method of measuring cardiac output requires estimation of
O2 content of aerial blood
O2 content of venous blood
O2 consumption per unit time
All of the above
Applying Fick&;s principle Output of left ventricle =Cardiac output= O2 consumption (mL/min)/ - Therefore this method requires the following valuesO2 consumption per unit time=Aerial O2 content =Venous o2 contentRef: Ganong's Review of Medical Physiology Twenty-Third Edition Page No:513
