Summary

Obstructive Sleep Apnea Syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) are two diseases that often coexist and are called overlap syndrome(OS). Compared to single OSAS, OS patients are more susceptible to serious hypoxia and hypercapnia especially during sleep, and are much more likely to result in pulmonary hypertension and cor-pulmonal.

With a more flexible expiratory positive airway pressure (EPAP), auto-trilevel ventilation may be superior to fixed bilevel positive airway pressure (BiPAP) ventilation in both removing residual obstructive sleep apnea hypopnea events and correcting hypercapnia simultaneously. The overall purpose of this study is to compare the curative effects between fixed BiPAP and auto-trilevel ventilations on OS patients.

Conditions

  • Overlap Syndrome

Interventions

DEVICE

BiPAP ventilation, auto-trilevel ventilation

Noninvasive ventilation including fixed BiPAP ventilation and auto-trilevel ventilation. Using the same IPAP, treatment include one night with BiPAP ventilation mode 1, one night with BiPAP ventilation mode 2 and one night with auto-trilevel ventilation mode. Each treatment last 8 hours for each night.
