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.
This study is a cross-sectional study involving Thai patients aged 18 years or older with suspected obstructive sleep apnea (OSA). Participants will undergo an in-laboratory sleep study. During the study, sleep technicians will use CPAP predictive equations to estimate the optimal CPAP pressure.
