Comparative Study of CPAP Predictive Equations and In-laboratory Manual Titration in Thai Patients With Obstructive Sleep Apnea

Recruiting now

Conditions studied: OSA - Obstructive Sleep Apnea

In brief

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.
