During a CPAP titration at 15 cmH2O, if the patient is restless and has frequent obstructive events, the BEST action is to:

• A. Change to bilevel
• B. Increase humidity
• C. Add a backup rate
• D. Initiate PAP ramp

Answer: (A)

When obstructive events persist despite a high fixed CPAP at 15 cmH2O and the patient is restless, switching to bilevel therapy is the most effective approach. Bilevel provides two pressures: a higher IPAP during inspiration to boost ventilation and keep the airway open, and a lower EPAP on exhalation to reduce work of breathing and improve comfort. This combination often reduces airway collapse and arousals, improving both sleep quality and tolerance to therapy. Humidification helps with comfort but won’t prevent obstruction, a backup rate mainly helps central apneas or hypoventilation, and a PAP ramp addresses initiation comfort rather than treating ongoing obstruction._SWITCHING to bilevel_ addresses the underlying issue of airway collapse while maintaining ventilation and comfort.
