Sleep monitoring at home in the elderly with obstructive sleep apnea syndrome induced by cognitive impairment;

The sleep monitor can let user know his sleep status in time.

This paper introduces the development of a household sleep monitor system,which can simultaneously monitor obstructive sleep apnea-hypopnea syndrome (OSAHS) and bruxism.

Methods 25 cases of OSAS and 8 cases of obesity hypoventilation syndrome(OHS) were diagnosed by a full night polysomnography(PSG), The patients were treated by nCPAP under the full night PSG.

Methods Forty-two over 60 patients with obstruction sleep apnea-hypopnea syndrome (OSAHS) diagnosed by polysomnography (PSG) and 42 matched but less than 60 years OSAHS patients were selected, who were admitted to our hospital from February 2003 to December 2005.

Objective: To realize the clinical characteristics\' difference of male and female patients with obstructive sleep apnea—hypopnea syndrome (OSAHS) by epidemiological investigation and polysomnography study.

Compare of Two Analysis Method for Polysomnography Partial Parameter;

Methods: 6 SB patients and 8 normal persons were monitored with polysomnography during the whole night.

Methodspolysomnography was conducted on 108 OSAHS patients and 37 simple snorers to record the minimumoxygen saturation level(MiO2) and the total recorded time spent below90% oxygen saturation(TS90%).
