Cardiac output in L/min divided by heart rate equals_______________?
Correct answer: D. Mean stroke volume
- A. Cardiac efficiency
- B. Cardiac index
- C. Mean arterial pressure
- D. Mean stroke volume
Explanation
Cardiac output is the product of heart rate and stroke volume, so dividing cardiac output by heart rate gives the mean stroke volume. Cardiac index instead is cardiac output adjusted for body-surface area.
