Resting energy expenditure was measured via ventilator-derived VCO2 indirect calorimetry on day 3 (8 patients) and day 4 (12 patients).
Resting energy expenditure was measured via ventilator-derived VCO2 indirect calorimetry on day 3 (8 patients) and day 4 (12 patients). Prescribed energy (1155±285.57 kcal/d) was significantly lower than both measured and predicted REE (p<0.001), but 70% of measured REE was not statistically different from prescribed energy (p=0.89). Prescribed protein (54.38±8.77 g/d) was significantly lower than recommended protein (72.25±15.69 g/d) (p<0.001).
