For the body surface area determination, the DuBois formula is used: BSA = 0.007184 x (Height in cm) 0.725 x (Weight in kg) 0.425. Example of a dosage calculation Body surface area (BSA) based dosing is a useful way to mitigate patient size variation in medication regimens. Cancer Chemother Rep 1970 54:225-35. Body surface area (BSA) calculations nursing questions for students! The BMI and BSA calculators estimate the Body Mass Index and Body Surface Area. Archives of Internal Medicine 17 (6): 863-71. After the age of 1 year, organ growth and physiological function conform more accurately to BSA than body weight. Abstract We retrospectively compared body surface area (BSA) using the Mosteller formula square root (H x (w/360)) and a simple weight-based BSA formula ([4Wkg+7]/ [90+Wkg]). This is an unprecedented time. In this quiz, you will be tested on how to solve pediatric body surface area dosage calculations. Doing so will create an intersection in the BSA scale [show me]. For example, a child is 37 inches (95cm) tall and weighs 34 lb (15.5 kg). Child dosage is calculated based on Body Surface Area (BSA) of adult and child. It can be calculated using various different formulas. The Body Surface Area formula. Du Bois formula: The formula is depends on the product of the weight of individual raised to the power 0.425 and height raised to the power of 0.725 and 0.007184, i:e: It’s a measure of the total estimated surface area that a human body occupies based on height and weight. Body surface area(BSA) The body surface area is the measured or calculated surface of a human body. We retrospectively compared body surface area (BSA) using the Mosteller formula square root(H x (w/360)) and a simple weight-based BSA formula ([4Wkg+7]/ [90+Wkg]). BSA = SQRT ( H * W / 3600 ) Where BSA is your body surface area (m^2) H is your height (cm) W is your weight (kg) This equation can be adjusted to use pounds and inches as the units as well.

Body surface area in children (image) You are viewing BNF for Children. This type of calculation requires the patient's weight and heights. Now, the average adult BSA (body surface area) is 1.7 m^2 (1.9 m 2 for adult males and 1.6 m 2 for adult females). Calculator Algorithm: Surface Area = W 0.5378 x L 0.3964 x 0.024265 But age and gender also play a role in addition to height and weight. B S A = 0.007184 × W 0.425 × H 0.725. weight. If you require BNF, use BNF. 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. 13, 14 The Costeff formula was developed in 1966 to be used in children and, like the Boyd formula, it … All trademarks used are the properties of their respective owners.

"A formula to estimate the approximate surface area if height and weight be known". BSA (m 2) = (height (cm) x weight (kg)/3600) ½. eg, BSA (m 2) = square root of (height (cm) x weight (kg)/3600) See also separate Sunburn article. BSA stands for body surface area.
