Study Comparing CPAP Predictive Equations and Manual Titration for Thai Adults with Obstructive Sleep Apnea

What this Trial Is About

Researchers are evaluating different predictive equations used to estimate the best continuous positive airway pressure CPAP settings for patients with obstructive sleep apnea OSA in Thailand. This observational study compares these CPAP predictive equations with the traditional in-laboratory manual titration method to find which equation most accurately predicts the optimal CPAP pressure. The study involves adult participants suspected of having OSA who will undergo detailed sleep assessments. Participants will take part in an in-laboratory sleep study using Type 1 polysomnography performed at the Sleep Center of Thammasat University. During the sleep study, sleep technicians will apply various CPAP predictive equations based on previous reliable research to estimate the ideal CPAP pressure needed to manage OSA. This approach will be compared directly with manual CPAP titration conducted in the lab. Throughout the study, participants will undergo sleep testing and monitoring to evaluate the accuracy of the CPAP pressure predictions. Researchers will measure how well the predictive equations match the optimal pressure determined by manual titration at baseline. Participants will be closely observed during the sleep study to gather data on their sleep patterns and breathing. The total participation time corresponds to the duration of the in-laboratory sleep study session.
