Influences of nasal continuous positive airway pressure to sleep architecture of obstructive sleep apnea syndrome / 中国实用内科杂志

Objective To investigate influences of nasal continuous positive airway pressure to sleep architecture of obstructive sleep apnea syndrome and the reason of daytime sleepiness. Methods 34 patients with severe OSAS were monitored with polysomnography (PSG) before and after nCPAP treatment. Results Apnea hypoventilation index (AHI) decreased and the lowest SaO2 increased and sleep architecture was improved in all patients. Conclusion The nCPAP therapy can effectively improve the disturbances of sleep architecture and respiratory parameters.
