The goal of this observational study is to compare predictive equations for continuous positive airway pressure (CPAP) with in-laboratory manual titration in patients with obstructive sleep apnea (OSA).
The main question the study aims to answer is:
Which CPAP predictive equation best predicts the optimal CPAP pressure in OSA patients in Thailand? Participants will undergo an in-laboratory sleep study.
Suspected OSA
Undergoing an in-laboratory sleep study
No indication for in-laboratory manual CPAP titration
Failure to determine an optimal CPAP pressure during in-laboratory manual CPAP titration
