If cardiac output is 6 L/min and heart rate is 75 bpm, what is stroke volume?

Cardiac output equals heart rate times stroke volume, so to find stroke volume you divide cardiac output by heart rate. Here, 6 L/min is 6000 mL/min. Dividing by 75 beats/min gives 6000 ÷ 75 = 80 mL per beat. So the stroke volume is 80 mL. This value is well within the typical adult range (about 70–100 mL per beat).
