ABW Estimated adjusted body weight ( kg) If the actual body weight is greater than 30% of the calculated IBW, calculate the adjusted body weight ( ABW) : ABW = IBW + 0. Adjusted body weight: AjBW = adjusted body weight: AjBW = IBW + 0. Estimated BMI = [ estimated body weight ( lb) / height ( in) 2] x 703 Estimated BMI = [ We( lb) / height( in) 2] x 703 For P, we used the following estimates for percentage of total body mass for common amputation levels.

This adjustment varies by indication for adjustment renal function estimations, but is generally an adjustment of 40% for drug dosing an adjustment of 25% for nutritional requirement estimation. Estimated ideal body weight in ( kg) Males: IBW = 50 kg + 2.

This is the IBW formula by Devine 1974 that is still used to calculate medication dosages or nutritional requirements in the case of obese patience but can also offer some reference in regard to the indicated weight. Finally find the Ideal Body Weight range for the amputation using the weight ranges above ( for an entire arm amputation use a body weight factor of 5% – see chart above) : Amputation Factor Weight: 169. 3% ) BOTH FOREARMS AND HANDS ( 4. 0% ) BOTH ENTIRE LEGS( 32.

## Body Diet

Finally, find the Ideal Body Weight range for the amputation using the weight ranges above ( for an entire arm amputation, use a body weight factor of 5% – see chart above) : Amputation Factor Weight: 169. 05 amp factor = 8.

47 lbs High range weight: 169. 47 lbs est amp weight = 160.

## Weight Burning

Adjusted body weight. In patients who are more than 30% of an amputation ideal weight, an " amputation adjusted weight" may be used. This adjusted body weight uses an adjustment factor of 0.

Adjusted body weight is commonly used for calculations like creatinine clearance. percent weight per amputation NO AMPUTATIONS BELOW KNEE ( 5.
