During PAP titration, the pressure should be increased until which combinations are eliminated?

During PAP titration, the pressure should be increased until which combinations are eliminated?

• A. Apneas and hypopneas
• B. Apneas, hypopneas and RERAs
• C. Apneas, hypopneas, RERAs and snoring
• D. Apneas, hypopneas, RERAs, snoring and leg movements

Answer: (A)

PAP titration aims to find the pressure that abolishes obstructive airway events caused by airway collapse during sleep. The primary targets are apneas and hypopneas, since these reflect clear obstruction and define the pressure needed to open the airway. RERAs are related arousal-related events and may improve with higher pressure, but they are not the essential criterion for establishing the titration pressure. Snoring and leg movements are not the respiratory events PAP titration seeks to eliminate as the key objective. Therefore, the pressure is increased until apneas and hypopneas are eliminated.
