What is the typical stroke volume range per heartbeat?

The typical stroke volume range per heartbeat is generally considered to be around 60 to 100 mL, depending on the individual's size, age, and overall heart health. The correct answer reflects the average stroke volume, which is the amount of blood the left ventricle pumps out with each heartbeat.

In a healthy adult at rest, the average stroke volume is usually around 70 mL, and during physical activity or increased metabolic demands, this volume can increase. Therefore, the range of 80-100 mL represents a more focused target for those who may be more active or who have higher cardiac performance levels.

Choosing a range of 80-100 mL accounts for these variations in heart function and captures the typical outputs as the heart works to efficiently meet the body’s demands. This understanding is crucial for healthcare professionals as it helps in assessing cardiac function and diagnosing potential heart-related issues.
