Calculate daily protein requirements for critically ill patients. Standard ICU patients: 1.2-2.0 g/kg/day of actual body weight. Severe burns (above 30% TBSA): 2.0-2.5 g/kg/day. Major trauma/multitrauma: 2.0-2.5 g/kg/day. Acute kidney injury (no RRT): 1.2-1.5 g/kg/day. AKI on CRRT: 1.5-2.5 g/kg/day due to protein losses in filtrate.
