Faisy et al developed an equation for predicting resting energy expenditure for a medical patient receiving mechanical ventilation. The authors are from multiple hospitals in Paris.

Patient selection: > 18 years and mechanically ventilated for > 24 hours in a medical intensive care unit (ICU)



(1) height in centimeters

(2) weight in kilograms

(3) minute ventilation in L per minute

(4) body temperature in °C


resting energy expenditure in kcal per day =

= (14 * (height in cm)) + (8 * (body weight in kg)) + (94 * (temperature in °C)) + (32 * (minute ventilation)) - 4,834
