How do you calculate adjusted BMI for amputation?
How do you calculate adjusted BMI for amputation?
How is BMI calculated?
- Step 1 – Calculate estimated body weight. We= W0/(1-P)
- Step 2 – Calculate estimated BMI. 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.
How do you calculate ideal weight for amputation?
For a man, use 106 pounds for the first 5 feet and then add 6 pounds for each additional inch: 106 lbs + (6 lbs per inch x 8 inches) = 154 pounds. This 5 foot, 8 inch patient with an entire arm amputation has an Ideal Body Weight range goal of approximately 161 lbs to 132 lbs.
How much weight do you lose after amputation?
Therefore, a man weighing 165 pounds will lose 7.62 pounds following a 3/4 leg, below-knee amputation. Woman, above-knee amputee, approximately half the thigh amputated – here we add the weight of the foot (1.29), the full weight of the leg (4.81) and half the weight of the thigh (0.5×14.78).
How much does an amputee weigh?
The weight of your prosthetic leg will depend on the type of prosthesis it is and its components. An average below knee prosthesis will weigh around 4 pounds and an average above knee prosthesis will weigh around 8-10 pounds.
How much does below knee amputation weigh?
The weight of your prosthetic leg will depend on the type of prosthesis it is and its components. An average below knee prosthesis will weigh around 4 pounds and an average above knee prosthesis will weigh around 8-10 pounds. Your prosthetic leg often weigh less than what your anatomical leg did.
How does amputation affect creatinine clearance?
Patients undergoing amputation are at particularly high risk of incorrect estimation of kidney function based on creatinine, due to malnutrition and loss of muscle mass [15,16,18,19], which may lead to inappropriate prescribing of renally-eliminated medications.
How much does a leg weight from the knee down?
Mean Segment Weights
| Segment | Males | Average |
|---|---|---|
| Total Leg | 16.68 | 17.555 |
| Thigh | 10.5 | 11.125 |
| Leg | 4.75 | 5.05 |
| Foot | 1.43 | 1.38 |
Do amputees burn more calories?
Simply put, amputees use more energy to walk. Energy efficient prosthetic feet and knees are designed to help alleviate some of this extra energy expenditure. Still, because amputees have higher energy demands, it is clear why a healthy diet and regular exercise are so important.
How much does a below knee prosthesis weigh?
around 4 pounds
An average below knee prosthesis will weigh around 4 pounds and an average above knee prosthesis will weigh around 8-10 pounds. Your prosthetic leg often weigh less than what your anatomical leg did.
What is the equation for BMI?
With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Since height is commonly measured in centimeters, an alternate calculation formula, dividing the weight in kilograms by the height in centimeters squared, and then multiplying the result by 10,000, can be used.
How much weight do your legs account for?
| Segment | Male | Female |
|---|---|---|
| Total Leg | 16.7% | 18.4% |
| Thigh | 10.5% | 11.8% |
| Leg | 4.75% | 5.35% |
| Foot | 1.43% | 1.33% |
How do you calculate BMI for amputation?
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. These estimates were arrived at through a review of the literature on body segment mass estimates and discussions with researchers.
What is the average weight of an amputee with amputation?
Amputation Factor Weight: 169.4 lbs x 0.05 amp factor = 8.47 lbs. High range weight: 169.4 lbs – 8.47 lbs est amp weight = 160.93 lbs. Low range weight: 138.6 lbs – 8.47 lbs est amp weight = 130.13 lbs. This 5 foot, 8 inch patient with an entire arm amputation has an Ideal Body Weight range goal of approximately 161 lbs to 130 lbs.
What is the Amputee Coalition body mass index tool?
Amputee Coalition has created this tool to help individuals with limb loss assess their weight status by calculating their body mass index. Body mass index (BMI) measures body fat based on height and weight.
Can an amputation affect your body mass index?
Since weighing more than you should increases your risk for health problems like heart disease, knowing your BMI can be an important part of taking care of yourself. If you’ve had an amputation, however, you need to account for the weight of the missing body part to calculate your BMI.
