If stroke volume (SV) is 80 mL and heart rate (HR) is 72 beats per minute, calculate the cardiac output (CO).
Using a formula,
\[
CO = SV \times HR
\]
Given data, \[
SV = 80 \, \text{mL}, \quad HR = 72 \, \text{beats/min}
\]
Putting values in the formula, \[
CO = 80 \times 72
\]\[
CO = 5760 \, \text{mL/min} = 5.76 \, \text{L/min}
\]
Therefore, the cardiac output is 5.76 L/min.
