Estimates the total surface area of a human body using various formulas. Body surface area (BSA) is the measured or calculated surface of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal body fat. BSA is an important factor in many physiological and clinical situations.

Calculates the average arterial pressure during a single cardiac cycle. MAP is considered a better indicator of perfusion to vital organs than systolic blood pressure.

Quantifies stroke severity based on a standardized neurological examination.

Calculates your recommended daily intake of macronutrients (carbohydrates, protein, and fat) based on your individual needs and goals.

This calculator assesses the level of frailty in older adults based on accumulated deficits. The Frailty Index is calculated by dividing the number of deficits present by the total number of deficits considered. A higher score indicates a greater level of frailty.

Calculates adjusted body weight, a weight value used for drug dosing or nutritional calculations in obese patients. This is a more accurate measure than actual body weight in such cases.

This calculator helps determine your eligibility and the next possible date for blood donation based on donation type and frequency.
