NCT03721445

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.

Outcome Measures

Primary Outcomes (1)

  • If changes in LF/HF ratio (Low frequency/High frequency ratio) could be a valuable predictor for CPAP acceptance in OSA patients?

    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.

    1 month

Secondary Outcomes (1)

  • If CPAP treatment could improve LF/HF ratio after 6 months of treatment in moderate to severe OSA patients?

    6 months

Study Arms (2)

CPAP opponent

CPAP opponent: moderate to severe OSA patients who refused CPAP therapy after PSG study and CPAP titration test.

CPAP acceptor

CPAP acceptor: moderate to severe OSA patients who accepted CPAP therapy after PSG study and CPAP titration test and had purchased a PAP at home for long term use.

Device: continuous positive airway pressure

Interventions

Could the changes of HRV between PSG night and CPAP titration night predict the CPAP adherence?

CPAP acceptor

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

moderate to severe OSA patients proved by PSG study and had been received CPAP titration test and had been prescribed CPAP therapy at home.

You may qualify if:

  • aged:20\~75y/o
  • PSG revealed moderate to severe OSA (apnea hypopnea index \[AHI\] ≧15/hour)
  • had been completed CPAP titration test

You may not qualify if:

  • aged\<20y/o or \>75 y/o
  • mild OSA, (AHI \<15/hour), or no OSA (AHI\<5/hour)
  • unstable cardiopulmonary disease, psychological diseases, using sleep pills.
