|---|---|
| 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 the name of the equation that used to calculate the energy of patients who is on a ventilator?
Ireton-Jones equations (1992 and 1997)) This equation is one of the most commonly used in ventilated patients.
What is VE in the Penn State equation?
minute ventilation
Ve = minute ventilation recorded from ventilator in L per minute. Revalidation: 74 Penn State (modified for BMI of 30kg/m2 or higher and age 60 years or older) 106 original Penn State equation.
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.
Which of these would be the most accurate measure of REE in an ICU patient?
Indirect calorimetry (IC) is considered as the gold standard to measure REE, by measuring oxygen consumption (VO2) and carbon dioxide production (VCO2).
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.
How is BMR derived?
BMR was derived using three methods: Harris-Benedict equation, Bioelectrical Impedance Analysis and Indirect Calorimetry.
What is the best method to assess calorie needs in critically ill patients?
Summary: Indirect calorimetry is the most accurate way to determine calorie needs in critically ill patients. Compared to indirect calorimetry, metabolic rate equations are accurate about 75% of the time.
How do I work out my cats RER?
Calculate the perfect portions for pets
- 30 x (body weight in kilograms) + 70 = RER for medium-sized patients. So if Spot weighs 44 pounds (or 20 kg), the equation would look like:
- 70 x body weight in kilograms to the ¾ power = RER for small/large patients.
