Body Surface Area (BSA)
Calculate weight in kilograms: 210 pounds ÷ 2.2 = 95.45 kg.Calculate height in centimeters: 6 feet, 3 inches = 75 inches x 2.54 cm/inch = 190.5 cm.Multiply height by weight and divide by 3600. (190.5 cm x 95.45 kg) ÷ 3600 = 5.Take the square root of 5 = 2.24 m2
What is BSA measurement?
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area 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 adipose mass.
How do you calculate BSA for a child?
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]). The participants were 363 children who underwent cardiac surgery from 1991 to 2000.
What is normal BSA?
The “normal” body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual. For example: Average body surface area for adult men: 1.9 m2.
How is BSA Dubois calculated?
The first of these formulae was proposed in 1916 by Du Bois and Du Bois (BSA [m2] = Weight [kg]0.425 × height (cm)0.725 × 0.007184]. It is a mathematical equation derived from measurements of weight and height of only nine patients including just a child.
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 )
How do you find area?
To find the area of a rectangle or a square you need to multiply the length and the width of a rectangle or a square. Area, A, is x times y.
What is the BMI equation?
Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared.
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.
