CPAP titration study
Also written as: CPAP — Continuous Positive Airway Pressure
A sleep study procedure to determine the optimal continuous positive airway pressure settings for treating obstructive sleep apnea.
Full Definition
A CPAP titration study is a specialized polysomnographic examination performed to establish the appropriate pressure settings for continuous positive airway pressure therapy in patients diagnosed with obstructive sleep apnea. During this overnight study, technologists gradually adjust CPAP pressure levels while monitoring sleep stages, respiratory events, oxygen saturation, and arousal patterns. The goal is to eliminate apneas, hypopneas, respiratory effort-related arousals, and snoring while maintaining sleep quality. Split-night studies may combine diagnostic and titration phases in a single session when severe sleep apnea is detected early in the recording period.
Usage
Usage note: CPAP should always be capitalized as it is an acronym. Use 'titration study' rather than 'titration test' in formal medical documentation.
