A stroke volume in the heart of 70 mL/cycle, with a pulse of 60 cycles per minute, results in a cardiac output of

Question

Quizplus · Accepted Answer

To calculate cardiac output, we need to multiply stroke volume (the volume of blood pumped out of the heart with each beat) by heart rate (number of beats per minute).
Cardiac output = stroke volume x heart rate
Given that stroke volume is 70 mL/cycle and the pulse is 60 cycles per minute, we can calculate cardiac output as follows:
Cardiac output = 70 mL/cycle x 60 cycles/minute
Cardiac output = 4,200 mL/minute
To convert mL to L, we divide by 1,000:
Cardiac output = 4.2 L/minute. Therefore, the best choice is A).
