Measured Versus Estimated Energy Requirement in the ICU Patients

Critically ill patients are highly susceptible to malnutrition, making accurate caloric estimation essential to prevent both underfeeding and overfeeding during the acute phase in the ICU. Although predictive equations (PE) are widely used to estimate energy requirement, indirect calorimetry (IC) remains the gold standard. This study aimed to compare energy requirements estimated by PE and IC across different BMI categories.
