During a bilevel titration, increasing the pressure of the Inspiratory Positive Airway Pressure (IPAP) is essential for eliminating hypopneas and snoring. IPAP works by providing a higher pressure during inhalation, which increases airflow and helps to keep the airway open more effectively during breathing. This is particularly important for patients who experience significant airflow limitations due to upper airway resistance that can lead to these events.

When hypopneas or snoring occur, they indicate episodes where the airway may be partially obstructed or collapsed. By adjusting the IPAP, the therapist can provide enough positive pressure to counteract the obstructive forces at play, promoting better ventilation and minimizing disruptions in the sleep cycle. Therefore, the increase in IPAP during a bilevel titration specifically addresses these issues by enhancing airflow during inhalation, thereby reducing or eliminating hypopneas and snoring.
