Total energy expenditure (TEE) refers to the total number of calories burned by an individual in a day, encompassing all forms of energy use including resting metabolic rate, physical activity, and the thermic effect of food. In the context of critical care settings, understanding TEE is crucial for ensuring that patients receive adequate nutritional support to meet their metabolic demands and promote recovery. Accurate assessment of TEE helps guide caloric intake, which is essential for maintaining energy balance in critically ill patients.
