Summary

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.

Detailed description

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.

Conditions

• OSA - Obstructive Sleep Apnea

Interventions

DIAGNOSTIC_TEST	Sleep test	Type 1 polysomnography will be performed in the Sleep Center of Thammasat (SCENT).
OTHER	Predictive equations of continuous positive airway pressure (CPAP)	CPAP predictive equations will be selected based on evidence from reliable studies.
