Body surface area (BSA) is the method that is mostly used in medicine and physiology.BSA medical is the computed or calculated surface area of a human body.. BSA is one sign that is used mostly for medical purposes to determine the total metabolic mass as compared to body weight and the advantage using BSA is that it is less affected by the abnormal adipose mass. BSA-Meban was most similar to the BSA-Mean with a mathematically perfect correlation and the least dissimilarity using Euclidean distance (ED), followed by the Mosteller estimate. In addition, formulas for the volume of plasma expander to be used in the prophylaxis and treatment of shock, trauma, and burn injuries are presented.
