Determine the cardiac output of a person with a Heart Rate of 69beats/min and stroke volume of 71mL.

Question

Question 46 options:

4899 L/min

4.89 L/min

489.9 L/min

4.89 mL/min

Answer 1

To determine the cardiac output, we need to multiply the heart rate (HR) by the stroke volume (SV).

Cardiac Output = Heart Rate (HR) * Stroke Volume (SV)

Cardiac Output = 69 beats/min * 71 mL

Cardiac Output = 4899 mL/min

Converting mL to L, we divide by 1000:

Cardiac Output = 4899 mL/min / 1000 mL/L

Cardiac Output = 4.899 L/min

Therefore, the cardiac output is approximately 4.89 L/min.
