Anthroprometrics
total energy expenditure
BEE with the activity level and/or stress level; determined if patient is hopsitalized
Anthroprometric calculations
BMI. BEE. TEE: BMI = wt (kg)/ht (m)2
BEE Miflin St. Joer
Female: {9.99 x wt kg} + {ht (cm) x 6.25} - {4.92 x age} -161 Male: {9.99 x wt kg} + {ht (cm) x 6.25} - {4.92 x age} -5
IBW
Males - 106 lbs +6 lbs per inch over five feet Females - 100 lbs + 5 lbs per inch over five feet Frame adjustments - small: subtract 10% - large: add 10% Obesity (>125% IBW); (Actual BW - IBW) x .25 + IBW
Daily caloric factors - Step 2
Sedentary(little or no activity) BMR x 1.2 confined to bed 1.2 x BEE Light activity(1-3 days per week) BMR x 1.375 ambulatory 1.3 x BEE Moderate activity(3-5 days per week) BMR x 1.55 av. act 1.5-1.75 x BEE Very active(6-7 days per week) BMR x 1.725 High activity 2. x BEE Extremely active(2 times per day) BMR x 1.9
Body Mass Index BMI
a technique that incorporates ht and wt to estimate critical fat values at which risk for disease increases.
Fluid requirements
children over 20kg - 1500cc + 30cc/kg over 20 kg young adults with large muscle mass - 40cc/lg/day adults (18-55) - 35cc/kg/day older adults - 30cc/kg/day
converting pounds to kilograms
divide pounds by 2.2, as there are 2.2 lbs/kg
protein requirements
healthy, non stressed - .8g/kg non-stressed hospital px - 1.g/kg malnourished hospital px - 1.2g/kg trauma, burns - 1.5-2.0g/kg head injury - 1.5-2.0g/kg
convert inches to centimeters
inches x .0254m
convert inches to meters
inches x 1m/39.37 in
Daily caloric req stress factor
liver disease - 1.0 to 1.16 minor surgery 1-1.1 wound healing - 1.2 to 1.5 Major surgery 1.1-1.3 surgery - 1.2 to 1.5 mild infection 1.0-1.2 severe infection 1.4-1.8 vent patients- 1.3 to 1.4 moderate infection 1.2-1.4 trauma 1.2-1.8
converting inches to centimeters
multiply inches by 2.54, as there are 2.54cm/inch
Dietary standards
myplate model, RDA, Dietary guidelines for americans 2010, nutrition labels, exchange lists
Basal energy expenditure
predicted using body weight-based equations including height, and sex;
nutritional screening
within 24 hours of admission to identify nutritional problems; lifestyle, disease process, age, gender, socio-economic status, and more;
At risk populations for deficiencies
