Overview
Brief Summary
This study aim to evaluate if the improvement of heart rate variability for the continuous positive airway pressure titration night can predict the short and long term continuous positive airway pressure adherence for patients with moderate to severe OSA.
Detailed Description
Heart rate variability (HRV) represents autonomic regulation and had been used in varies situation, especially the associated with cardiovascular outcomes and psychological diseases. HRV was also well known associated with the severity of obstructive sleep apnea (OSA) and could be improved after adequate treatments for OSA. Continuous positive airway pressure (CPAP) is the first choice of treatment for OSA and had been proved to able to improve HRV in OSA patients. However, the CPAP adherence is always problematic. Many CPAP predictors had been well documented but the HRV is never evaluated to be a potential predictor of CPAP adherence. Therefore, this study will evaluate the changes of HRV for polysomnography (PSG) night, for CPAP titration night to see if the changes of HRV in the CPAP titration night could predict CPAP adherence for OSA patients in Taiwan.

Outcomes
Primary Outcomes
If changes in LF/HF ratio (Low frequency/High frequency ratio) could be a valuable predictor for CPAP acceptance in OSA patients?
Time Frame: 1 month
Changes of LF/HF ratio between PSG study night and CPAP titration night will be measured and evaluated its association with CPAP acceptance of one month CPAP trial at home in moderate to severe OSA patients.
Secondary Outcomes
- If CPAP treatment could improve LF/HF ratio after 6 months of treatment in moderate to severe OSA patients?(6 months)
