The most commonly used formula now is that of Mosteller, published in 1987 in The New England Journal of Medicine. 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.
How do you manually calculate body surface area?
We conclude that the simple Jacobson equation for body surface area (5): BSA, m2 = (Wt(kg) + HT(cm)- 60)/100 has sufficient agreement with the widely used Du Bois equation to allow clinical use in adults.
Is BSA and BMI the same?
While Body Mass Index (BMI) is a measure of a person’s body fat mass, Body Surface Area measures the total surface area of a person’s body and is frequently used in order to calculate drug dosage and the amount of fluids to be administered by IV. Various formulas have been used over the last century to calculate BSA.
What is a normal BMI and BSA?
For a distribution of BM/BSA values comparable to the distribution of normal BMI values, the range 35.5-39.9 kg/m2 is chosen as normal, although it covers BM range 50 to 90 kg. The proposed normal BM/BSA range suggests that heavy adults with less than 2 m of height are not obese only if they are less than 90 kg.
What is the unit of body surface area?
The body surface area (BSA) of any adult, when derived from the arithmetic mean of the different values calculated from four independent accepted formulae, can be expressed accurately in Systeme International d’Unites (SI) units by the simple equation BSA = 1/6(WH)0.5, where W is body weight in kg, H is body height in
How do you convert mg/kg to MG m2?
To convert dose in mg/kg to mg/m2 of humans or animals is carried out using the Km factor in table1 as: mg/m2 = Km × (mg/kg) (Eq.
Why is the rule of nines important?
Why Is the Rule of Nines Helpful? The rule of nines gives an idea of how much of your total body’s surface area a burn takes up. This informs treatments based on the size and intensity of the burn injury. Emergency medical responders are some of the medical workers who use the rule of nines most.
What is BSA in health chart?
Values for body surface area (BSA) are commonly used in medicine, particularly to calculate doses of chemotherapeutic agents and index cardiac output. Various BSA formulas have been developed over the years.
What is a normal BSA for a woman?
Among them the average BSA for men was 1.91 m2 and for women was 1.71 m2.
How do you calculate BSA for chemotherapy?
Cancer Chemother Rep 1970;54:225-35.
Equation: BSA (m2) = 0.0235 x Height(cm)0.42246 x Weight(kg)0.51456Equation: BSA (m2) = 0.024265 x Height(cm)0.3964 x Weight(kg)0.5378Equation: BSA (m2) = SQR RT ( [Height(cm) x Weight(kg) ]/ 3600 )
