Bsa body measurement. Body surface area bsa bsa measures the total surface area of the body and is used to calculate drug dosages and medical indicators or assessments. It explains why the mosteller formula was adopted for use by the pharmacy and therapeutics committee of the cross cancer. Body surface area bsa is simply a measurement of the surface area of your body. While widely used in population health studies the bmi equation has been critiqued for its use in individual diagnoses for determining whether someone is overweight or obese. This parameter shows the metabolic mass rather than the body weight for clinical purposes. Bsa m 2 00003207 x heightcm 03 x weightgrams 07285 00188 x loggrams.
The first formula was developed by du bois in 1916 and since then several others have been developed. It is probably not worth the trouble to debate about which formula may or may not be slightly better. Its normal value is considered to be 17m². Bsa is a measurement used in many medical tasks. Various body surface area formulas have been developed over the years originally by drs du bois du bois followed by gehan and george haycock boyd and mosteller. These formulas all give slightly different results.
Ancel keys a physiology professor used quetelets equation as part of a 1972 published report on obesity and created the name body mass index or bmi. The boyd formula 5. The mosteller formula is recommended 6to learn more about the issues and differences in bsa formulas read the bsa standards report by thanh vu bscpharm. To address it scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body. Bsa calculator tells us about the surface area of a person while the body mass index is a measurement of the degree of how overweight a person is. The body surface area formula or bsa formula must not be confused with the body mass index because both of them are completely different terms and things.
Direct measurement of bsa is difficult and as such many formulas have been published that estimate bsa. Nevertheless there have been several important critiques of the use of bsa in determining the dosage of medications with a narrow. In physiology and medicine the body surface area bsa is the measured or calculated surface area of a human bodyfor many clinical purposes bsa is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. What is body surface area. This is because the unusual body adipose mass doesnt affect it. In medicine body surface area bsa of a human body is calculated to determine the surface area of the ones body to measure the metabolic mass for dosages.
Body surface area calculator. Since the body is a complex figure making an accurate measurement of its surface is a considerable challenge. There were various formulas to calculate the bsa. The measured surface area of the body is termed as the body surface area or bsa in physiology and medicine. The calculator below provides results for some of the most popular formulas.
