The patients palmar surface including their fingers = 1% TBSA. 2 A. Body Surface Area. Body surface area % Body Surface Area. Cardiac Index (CI) It is often clinically determined to measure the metabolic mass of the body and is less likely to be affected by fat mass. What Is Body Surface Area? Estimation of treated BSA of a baby, empirically, involves topographically mapping the 3-D surface of a baby onto a 2-D surface and then estimating the area of the resultant non-standard shape. It is expressed usually expressed in m 2. the area of the external surface of the body, expressed in square meters (m2); used to calculate metabolic, electrolyte, nutritional requirements, drug dosage, and expected pulmonary function measurements. Farlex Partner Medical Dictionary Farlex 2012 body surface area The body surface area (BSA) is a mathematical relationship, expressed in m 2, with the result obtained from the height and weight of the patient. This measure is used in order to obtain a more comprehensive parameter of the patients weight, to define more appropriate dosage. BACKGROUND: Left ventricular hypertrophy (LVH) is a well known independent risk factor for cardiovascular events. Surface area is important to know situations where we want to wrap something, paint something, and eventually while building things to get the best possible design. The total surface area of the human body. 2. At present the BSA calculations are used in several medical fields. The body surface area is used for the correction of many clinical measurements for better approximation and comparability of that respective parameter. The first formula was developed by Du Bois in 1916 and since then, several others have been developed. Another essential use of body surface area is in calculating a patient's cardiac index, a measure of the physiologic status of cardiac function.
