What should be initial pressure setting be for a CPAP titration study?

• A. 4-6 cm
• B. 1 cm
• C. 2-4 cm
• D. 6-8 cm

Answer: (A)

Starting CPAP titration at a low, yet effective level helps balance opening the airway with patient comfort. About 4 cm H2O is typically enough to splint the airway in many adults with OSA without causing unnecessary discomfort or leaks, and it provides a safe baseline from which to increase if needed. Using a range of 4–6 cm H2O as the starting point gives the clinician flexibility to reach the minimum pressure that eliminates apneas and maintains adequate oxygenation during the sleep study. Pressures much lower than this are likely insufficient to prevent airway collapse, while pressures much higher than this can cause discomfort, more leaks, and arousals, complicating the titration. So, 4–6 cm H2O is the best starting range for most CPAP titration studies.
