Abstract:

Objective   To explore the clinical value of the micro-movement sensitive mattress sleep monitoring system (MSMSMS)in auto-pressure titration for patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods   71 OSAHS patients treated by respirator with auto-pressure titration were simultaneously monitored by MSMSMS and the results were compared with that of pre-therapy, as well as the automatic pressure titration results between MSMSMS and respirator. Results   59 patients (83.1%) completed the whole night pressure titration while 12 patients (16.9%) didn’t. Compared with the pre-therapy data, MSMSMS showed that the sleep apnea-hypopnea index(AHI) of the 59 patients was reduced 88.1%±6.6% on average at titration night and the blood oxygen saturation was also significantly improved. The titration results showed that AHI monitored by MSMSMS was greater than that by the respirator(P＜0.001). Conclusion   MSMSMS shows many advantages, such as convenience and no interference. As a simultaneous monitoring method, MSMSMS could be adopted to ensure the quality of sleep of OSAHS patients during the auto-pressure titration. With the titration results from respirator, it could be better to evaluate the initial treatment effect and compliance of patients with OSAHS and guide the treatment.
