basal energy expenditure

basal energy expenditure

The amount of oxygen consumed while resting and fasting, extrapolated to 24 hours, roughly equivalent to 25 kcal/kg. BEE is used to determine an individual’s caloric needs: it is multiplied by level of activity (e.g., 1.2 for bed rest; 1.4 for moderate activity) and by an injury factor (1.2 for pneumonia, surgery; 1.3 for major injury, 1.5–1.6 for severe sepsis).
