What is the approximate range for Stroke Volume in adults?

The approximate range for stroke volume in adults typically falls between 70 to 120 milliliters per beat. Stroke volume refers to the amount of blood ejected by the heart with each beat, and this range is generally accepted based on physiological studies of adult cardiac function.

While 50-100 cc per beat presents a narrower estimate and could be seen as a simplified interpretation in some scenarios, it doesn't encompass the full physiological range identified in clinical practice. Various factors can influence stroke volume, such as body size, fitness levels, and health conditions, but the broader range acknowledges the variability in individual cardiac output under different circumstances. Therefore, the correct range provides a more comprehensive understanding of typical stroke volume in the adult population.
