What is the cardiac output when oxygen (O₂)consumption = 200 mL/min,arterial O₂ content = 21 vol%,and mixed venous O₂ content = 15 vol%?
A) 3.3 mL/min
B) 4.3 mL/min
C) 5.3 mL/min
D) 6.3 mL/min

Quizplus · Accepted Answer

Cardiac output = oxygen consumption ÷ (arterial O₂ content - mixed venous O₂ content).21 vol% = 21 mL/100 mL and 15 vol% = 15 mL/100 mL.Therefore,200 mL/min ÷ (21 mL/100 mL - 15 mL/100 mL)10 = 3.3 mL/min.
