For the critically ill, mechanically ventilated patient, the Penn State equation would be most appropriate. Since Mr. Campbell is not mechanically ventilated, it is best to use a 25-35 kcal/kg American Chest Physician's nomogram.
25-35 kcal/kg: (25 x 70.9 kg) to (35 x 70.9 kg) = 1773-2482 kcal per day (approx. 1800-2400 kcal/day)
