body surface area

Body surface area (BSA) refers to the total area covered by a person’s skin, measured in square meters. It is an important measurement often used in medicine to determine appropriate medication dosages, assess health status, and evaluate organ function, especially in children, burn victims, and patients needing specialized treatments. BSA takes into account height and weight to estimate the size of the body’s external surface. Calculations like the Mosteller formula provide an accurate estimate, helping healthcare providers tailor treatments more precisely based on a person’s physical size.
