What is the normal range for ejection fraction in percentage?

Ejection fraction (EF) is a key measurement used in cardiology to assess the heart's pumping efficiency. It represents the percentage of blood that is pumped out of the heart's ventricles during each contraction. The normal range for ejection fraction typically falls between 55% and 75%. This means that in a healthy heart, at least 55% of the blood in the left ventricle is ejected with each heartbeat, indicating good cardiac function.

In clinical practice, ejection fraction is particularly important for diagnosing and managing heart conditions. An EF below the normal range can signal heart disease or dysfunction. Therefore, understanding the typical parameters, such as the 55-75% range, is crucial for healthcare professionals, including cardiovascular perfusionists, as it guides monitoring and treatment decisions.

Choosing this specific range highlights the importance of recognizing how ejection fraction serves as a reliable indicator of cardiac health and function.
