Question 7

What is Stroke Volume and Cardiac Output?

Answer 7

Stroke volume (SV) is the amount of blood moved in one beat.

Cardiac output (CO) is the amount of blood moved in 1 minute.

Cardiac output is equal to heart rate times stroke volume.

Mathematically, cardiac output can be expressed as follows: CO = HR × SV

For example: 70 beats/min × 75 mL/beat = 5,250 mL/min or 5.25 L/min
