What is Ellen's Body Surface Area (BSA)?

Answer: To calculate Ellen's BSA, we can use the DuBois formula: BSA=(weight^(0.425) * height^(0.725)) * 0.007184. Using the given data: Weight: 191 lb Height: 4 ft 4 in We first need to convert Ellen's height to centimeters. Since 1 ft = 30.48 cm and 1 inch = 2.54 cm, Ellen's height would be 132.08 cm. Next, we substitute the values into the formula and calculate BSA: BSA = (191^(0.425) * 132.08^(0.725) * 0.007184 = 1.51 square meters Therefore, Ellen's BSA is approximately 1.51 square meters.

Explanation:

Body Surface Area (BSA) is an important factor in medical calculations, especially for dosing medications and assessing metabolic rates. BSA is calculated using various formulas, such as the DuBois formula that we used in this case.

The DuBois formula takes into account a person's weight and height to calculate their BSA. In Ellen's case, her weight is 191 lb and her height is 4 ft 4 in. By converting her height to centimeters and plugging in the values into the formula, we were able to determine that Ellen's BSA is approximately 1.51 square meters.

It's important to remember that BSA calculations are estimates and may vary slightly depending on the formula used. However, for medical purposes, BSA provides a more accurate assessment of a patient's body size compared to using weight or height alone.

Understanding a patient's BSA is crucial for various medical procedures, especially for determining appropriate medication dosages, determining nutritional needs, and assessing overall health status. By accurately calculating BSA, healthcare providers can provide better and more personalized care to their patients.
