What is the normal stroke volume range for an adult?

The normal stroke volume range for an adult is typically between 70-120 mL per contraction. This measurement represents the volume of blood pumped from the left ventricle of the heart with each heartbeat. It's crucial in assessing cardiac output and overall heart function.

While 50-100 mL per contraction might appear to capture a portion of the lower end of effective stroke volume, it does not fully encompass the standard expected physiological range for adults, especially considering that factors such as body size and physical fitness can cause variations. The stroke volume can indeed be higher, reaching up to about 120 mL depending on individual characteristics and physiological conditions, such as during intense exercise or in well-conditioned athletes.
