- Maintaining adequate, but not excessive, cuff pressure

- Trach care every 8 hours

- Oral care every 2 hours

- Optimizing hemodynamics


Increased cuff pressure puts patients at increased risk for trachel necrosis, therefore it should be closely monitored. Maintaining a pressure below 20 mm Hg reduces this risk. Oral and trach care do not in themselves prevent this. While optimal hemodynamics are essential, they will not directly impact tracheal necrosis as closely as cuff pressure.
