For example: Average body surface area for adult men: 1.9 m2. 2 The estimated BSA of an older child is five times that of a premature neonate. BSA = 0.024265 W 0.5378 H 0.3964. This table compares the different formulas: Body is divided in 9% areas. Youve probably heard of BMI (Body Mass Index) in reference to overall health, weight loss or exercise, but Total body surface area is an assessment measure of burns of the skin. In adults, the "rule of nines" is used to determine the total percentage of area burned for each major section of the body. In some cases, the burns may cover more than one body part, or may not fully cover such a part; in these cases, burns are measured by using the casualty's palm as a reference point for 1% of the body. Egton Medical Information Systems Limited has used all reasonable care in compiling the information but make no warranty as to its accuracy. This parameter shows the metabolic mass rather than the body weight for clinical purposes. It can be calculated using a nomogram (a diagram that gives you the BSA of the patient) or specific formulas, which is what this review will cover. Body surface area (BSA), as the name suggests, is the calculated or estimated surface area of a persons body. alkapton b's a class of substances with an affinity for alkali, found in the urine and causing the condition known as alkaptonuria.
