Rationale: Whenever the amount of H2O being delivered to the patient is less than 44 mg/L, a humidity deficit exists. This decreased H2O delivery can result in thickening of pulmonary secretions, with an increased potential of mucous plugging and atelectasis distal to the plugs. Because cooler air cannot hold as much H2O as warmer air, decreasing the heater temperature increases the humidity deficit. 3) The respiratory therapist is administering acetylcysteine (Mucomyst) via a handheld nebuli...
