# Body surface area dosing

In order to calculate the maintenance doses or to compare the high dose use with the maintenance need, the glucocorticoid **dosing** is stated in terms of the BSA. 3. For gaining the appreciation of true glomerular filtration rate (GFR), the renal clearance needs to be divided by the BSA, i.e 1.73 m². The **BSA calculator**, however, is easy to use and help you calculate the BSA. Standard BSA is measured to be about 1.7 m2. There are many factors on which the BSA is dependent upon, such as, height, age, weight, and gender etc. However, it must be remembered that the BSA for different age groups is different..

It used the reports of resveratrol **dosing** in animals, crudely extrapolated to humans, to argue that the **body** **surface** **area** normalization (BSA) method was a superior technique for dose estimation across species. Over the years, though, the BSA method has taken some flak in the literature.

**Body** **surface** is calculated from weight and height according to the conventional DuBois nomogram, or from weight alone. The use of this rule automatically provides the infant with a larger per kilogram **dose** than the older child. This is because **surface** **area** increases less rapidly than weight as the **body** grows. Topics: **body** weight, nomogram, serum. . Jun 18, 2012 · Drugs are generally dosed according to one of three approaches: fixed **dosing**, weight-based **dosing**, or **body** **surface** **area**–based **dosing**. **Dosing** based on **body** weight or **body** **surface** **area** assumes that drug pharmacokinetic parameters increase in proportion with increasing **body** size..

Methods: Three BSA bands were defined: BSA<1.7 m (2), 1.7 m (2)≤ BSA<1.9 m (2), BSA ≥ 1.9 m (2) and each patient **dose** was calculated based on a unique BSA-value per band (1.55, 1.80, and 2.05 m (2), respectively).. Web. **Body** **surface** **area** (BSA): measured or calculated **surface** **area** of a human **body**. The BSA is frequently used in determining the dosage of medications with a narrow therapeutic index, such as chemotherapeutic agents. The four most common equations used to calculate the BSA are included in this calculator. Results can be exported in pdf format. Height :.

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. 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. Web.

Updated equations for estimated glomerular filtration rate (eGFR) without race have been published. Likewise, de-indexation of eGFR to **body** **surface** **area** (BSA) has been recommended by regulatory guidance for drug **dosing** in renal impairment. Clinical data justifying these recommendations for drug **dosing** are sparse.

To estimate your **body** **surface** **area** our BSA calculator uses the following formula [1]: 0.20247 x height (m)0.725 x mass (kg)0.425 where height is in meters and mass is in kg. The result is in squared meters, which easily be converted to square feet, inches or yards as needed.

Jul 28, 2019 · Values for **body** **surface** **area** (BSA) are commonly used in medicine, particularly to calculate doses of chemotherapeutic agents and index cardiac output. The overall BSA was 2.04 +/- 0.24 m (2): 1.81 +/- 0.19 m (2) in normal-weight, 1.99 +/- 0.16 m (2) in overweight, and 2.21 +/- 0.22 m (2) in obese subjects. What is BMI and BSA?. The **BSA calculator**, however, is easy to use and help you calculate the BSA. Standard BSA is measured to be about 1.7 m2. There are many factors on which the BSA is dependent upon, such as, height, age, weight, and gender etc. However, it must be remembered that the BSA for different age groups is different..

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.
