Question: 1 / 445

Cardiac output is equal to:

SV x HR

Cardiac output is defined as the amount of blood pumped by the heart per unit of time. Therefore, cardiac output is equal to the stroke volume (the amount of blood pumped with each heartbeat) multiplied by the heart rate (the number of times the heart beats per minute). Option B is incorrect because dividing the stroke volume by the heart rate would give an inaccurate measurement since it's a smaller number divided by a larger number. Option C is incorrect because it subtracts two different units (beats per minute and amount of blood), which does not give a meaningful measurement. Option D is also incorrect because dividing the heart rate by the stroke volume would give an inaccurate measurement for the same reason as option B. Therefore, the correct answer is option A, SV x HR.
