How do you calculate patient energy requirements?
Concerning the energy supply to patients, the guideline recommends 25 kcal/kg of usual body weight for most patients. In case of obese patients (body mass index [BMI] ≥ 25 kg/m2), the recommendation is to estimate energy requirements based on the ideal body weight.
What is the Ireton Jones equation?
Table 1
| Equation name | Calculation of resting energy expenditure |
|---|---|
| Females: 161 + (10 × ActBW) + (6.25 × Ht) – (5 × Age) | |
| Ireton-Jones equation for obesity 27, 36, 37 | Males: 606 + (9 × ActBW) – (12 × Age) + 400 (if ventilated) + 1400 |
| Females: ActBW – (12 × Age) + 400 (if ventilated) + 1444 |
What is Penn State equation?
Original Penn State equation: RMR (kcal per day) = Mifflin(0.96) + Tmax(167) + Ve(31) – 6,212.
What is the Toronto equation or Schofield formula?
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985….Men:
| Age | Equation (kcal/day) | SEE |
|---|---|---|
| 3–10 | 22.706 × W + 504.3 | 67 |
| 10–18 | 17.686 × W + 658.2 | 105 |
| 18–30 | 15.057 × W + 692.2 | 153 |
| 30–60 | 11.472 × W + 873.1 | 167 |
How is Schofield equation calculated?
The Schofield Equation allows one to estimate the basal metabolic rate (BMR) in calories based on a few simple variables: gender, age, and weight….Schofield – Basal Metabolic Rate equations:
| Age (years) | Males | Females |
|---|---|---|
| 30-59 | BMR = 11.472 x (wt kg) + 873.1 SEE = 167 | BMR = 8.126 x (wt kg) + 845.6 SEE = 111 |
When is Penn State equation used?
Modified Penn State Equation, also known as PSU 2010 was validated in 2010 by the Academy (Grade II) (3). This formula is recommended to be used for patients with BMI over 30 and older than 60 years of age (3).
How do you calculate Mifflin-St JEOR?
The Mifflin-St Jeor Equation This BMR formula is as follows: BMR (kcal / day) = 10 * weight (kg) + 6.25 * height (cm) – 5 * age (y) + s (kcal / day) , where s is +5 for males and -161 for females.
How many kcal ml are in 1 ml of propofol?
Propofol contains 1.1 kcal/ml. Therefore, at an infusion rate of 20 ml/h over 24 h, the caloric value of the propofol infusion is 20×1. 1 × 24=528 kcal.
How is BMR calculated in Schofield?
The Schofield Equation is a method of estimating the basal metabolic rate (BMR) of adult men and women published in 1985….Men:
| Age | Equation (kcal/day) | SEE |
|---|---|---|
| 10–18 | 17.686 × W + 658.2 | 105 |
| 18–30 | 15.057 × W + 692.2 | 153 |
| 30–60 | 11.472 × W + 873.1 | 167 |
| > 60 | 11.711 × W + 587.7 | 164 |
How accurate is the Schofield equation?
Agreement between Measured RMR and Predicted RMR. Among the pre-existing equations, the Schofield equation provided the highest percentage of accurate prediction with 59.1%, 18.7% overprediction, and 22.2% underprediction.
