Question

Calculate the cardiac output of an individual having 70 heart beats/min with a stroke volume of 55 ml.

• A. 3750 ml
• B. 125 ml
• C. 3850 ml
• D. None of the above

Answer 1

The Correct Option is C

The cardiac output (CO) is calculated using the formula:
\[ CO = \text{Heart rate (HR)} \times \text{Stroke volume (SV)} \]
Given:
Heart rate (HR) = 70 beats/min
Stroke volume (SV) = 55 ml/beat
Now, calculate the cardiac output:
\[ CO = 70 \, \text{beats/min} \times 55 \, \text{ml/beat} \]
\[ CO = 3850 \, \text{ml/min} \]

Thus, the cardiac output is 3850 ml/min.
