What is the typical cardiac stroke volume in a healthy adult?

The typical cardiac stroke volume in a healthy adult is approximately 70 mL. Stroke volume refers to the amount of blood ejected by the left ventricle of the heart with each heartbeat. In a healthy adult at rest, this value tends to be around 70 mL, which plays a crucial role in maintaining adequate circulation and blood pressure throughout the body.

Understanding stroke volume is essential for assessing cardiac function and overall cardiovascular health. Factors such as heart rate and contractility also influence cardiac output, which is a product of stroke volume and heart rate. The normal range can vary slightly based on individual differences, activity level, and overall health, but 70 mL is a widely accepted value in clinical practice for a resting adult. Values outside of this range can indicate various health conditions or physiological changes.
