Abstract:
Objective To assess the efficiency of mattress-type micro sensitive monitor(MMSM) in sleep monitoring. Methods Forty patients diagnosed as obstructive sleep apnea-hypopnea syndrome (OSAHS) by polysomnography (PSG) were randomly chosen, then received MMSM examination within 2 -5 days. The results of both methods were compared, using the respiratory disturbance index, sleep efficiency, and obstructive factors as indicators. Results All 40 patients were diagnosed as OSAHS, which were consistent with the results of PSG. There was no statistical difference when comparing the apnea hypopnea index (AHI, (-x)± s, 35.6 ± 21.3 and 37. 6 ± 18. 8, respectively) and the ratio of rapid eyes movement (REM) stage (15.0 ± 4. 5) % and (15.8 ± 6. 3) %, respectively (t were 1. 867 and 1. 014,P >0. 01). Some statistical sense was found when patients'deep sleep, shallow sleep and sleep efficiency were compared (P <0. 01). According to the severity diagnosed by PSG, patients with mild, moderate and severe OSAHS were 11, 7 and 22 cases, respectively, Comparing by MMSM, 2, 19 and 19 cases,respectively. Among seventeen volunteers diagnosed by PSG as normal subjects, 2 of them were diagnosed as mild OSAHS. The sensitivity of MMSM was 100. 0% and the specificity was 88. 2%. Conclusions With regard to the diagnosis of OSAHS, MMSM is well consistent with PSG. The MMSM can be applied clinically as a monitor technique.
