Question

with an oxygen consumption of 2.3 L/min, heart rate of 139 b/min, an arterial SO2 of 98%, a venous SO2 of 68%, an arterial oxygen content of 201 ml/L, and a venous oxygen content of 116 ml/L

What is the cardiac output of this individual in L/min

Answer 1

Fick principle is used to measure the cardiac output  by determining the amount of oxygen consumed in the  body in a given period of time and dividing this value by  the arteriovenous difference across the lungs. Here ,

thus cardiac output is 0.27 L per minute.
