The therapist is performing airway care on a mechanically ventilated patient who is intubated with a Hi-Lo Evac endotracheal tube.

Leave both the cuff pressure and vacuum pressure set at their respective levels. D. Leave the cuff pressure at 30 cm H2O, and decrease the vacuum pressure to 70 mm Hg.
