Gastric distention is less common in alert and cooperative patients because they can control their swallowing and breathing more effectively. It is more likely at high airway pressures due to the increased force of air that can lead to air being pushed into the stomach. It poses a significant risk in obtunded patients as they have diminished protective airway reflexes, making them more susceptible to complications like aspiration. Gastric distention is not considered a harmless effect of IPPB; it can lead to discomfort, vomiting, and aspiration, which are serious complications.
