There are several estimation formulas available for use, the most common one being that published by Mosteller in 1987. Body surface area (BSA) based dosing is a useful way to mitigate patient size variation in medication regimens. The non-muscle cell mass and the muscle cell mass reach a 1:4 ratio in men whereas in women a 1:35 proportion--which is more favorable for pregnancy and lactation--is reached. An adult male applies a cream once daily to the dorsal and volar surfaces of both feet and both hands. To address it, scientists in the early 1900s took measurements via melted paraffin and paper strips applied to their body. In the SI system this quantity is measured in W/m 3, and if the wavelength is measured in micrometres then this quantity is measured in W/(m 2 m m). For every like, I hear a bell, and smile, and you get wings. According to Mosteller's "simplified calculation of body-surface area In metric terms" the body surface area = the square root of product of the weight in kg times the height in cm divided by 3600. Each tool is carefully developed and rigorously tested, and our content is well-sourced, but despite our best effort it is possible they contain errors. The Mosteller formulas have been developed over the years, originally by body weight-to-surface area synonyms, body weight-to-surface area pronunciation, body weight-to-surface area translation, English dictionary definition of body weight-to-surface area. Its not very easy to do a direct measurement of BSA, so several formulas have been published to estimate BSA. Optional Medication Dose Calculator.

Ancel Keys, a physiology professor, used Quetelet's equation as part of a 1972 published report on obesity and created the name body mass index or BMI. Calculates BSA for medication doses and includes descriptive statistics. Direct measurement of BSA is difficult, and as such many formulas have been published that estimate BSA. These formulas all give slightly different results. probably not worth the trouble to debate about which formula may or may not be The same applies for total daily energy expenditure calculations. 1.

Using BSA may help prescriber's dose more optimally to improve drug efficacy, minimize drug toxicity, and account for some changes in pharmacokinetics depending on patient factors. Source for information on body surface area: A Dictionary of Food and Nutrition dictionary. 1.Weight? Fingertip units is a term coined by CC Long and AY Finlay who, in an article published in 1991, described a convenient way to measure how much cream to prescribe to a patient with skin disease. 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. The surface area method relates the patient's fluid and electrolyte needs to their body's surface area. Ancel Keys, a physiology professor, used Quetelet's equation as part of a 1972 published report on obesity and created the name body mass index or BMI. Body Mass Index: kg/m 2. It can be visualized as the amount of paint that would be necessary to cover a surface, and is the two-dimensional counterpart of the one-dimensional length of a curve, and three-dimensional volume of a solid. Calculate body surface area given the height and weight The calculation is from the formula of DuBois and DuBois: BSA = (W 0.425 x H 0.725) x 0.007184 where the … But it looked quite Next Question.

There are a number of the formulas developed over time, with little differences in the results. Effect of body surface area calculations on body fat estimates in non-obese and obese subjects. but I'm having second thoughts now. BSA calculations are useful when determining different body characteristics, for example energy expenditure in the form of BMR, RMR (REE), RDEE, TDEE, which are in turn used when determining dietary and nutritional needs. 0.018 0.050 0.25 70.0 TABLE 1 MECHLORETHAMINEDOSAGE Surface area (sq.

Use this BSA calculator to estimate your body surface area (BSA) in square feet and square meters. Calculate BMI and Body Surface Area using Mosteller formula. Other influential factors include the age and gender of the individual. On my Body Mass Index calculator, it has hover pop-ups for weight and height, so you don't have to type. This is a slight variation of the DuBois & DuBois body surface area formula, derived in 1916 [4], modified for easier calculation with height expressed in meters instead of centimeters and the results are practically identical. Using these BSA formulas, body surface area will be figured out in square meters. Hi, and welcome. Archives of Internal Medicine 17:863–871. [email protected]. There are several estimation formulas available for use, the most common one being that published by Mosteller in 1987. or Share. He uses about 3 g per day (2 feet x 2 units PLUS 2 hands x 1 unit, x 0.5 g = 3.0 g).
