Older adults, in particular, experience varying levels of sleep disorders. Estimates show that about 52% of Taiwanese snore, and more than 450,000 people in Taiwan suffer from Obstructive Sleep Apnea Syndrome (OSAS)1. The objective of this study is to develop a low-price portable prototype system for the automatic monitoring and correction of patients with OSAS. Method We focus on the design and implementation of the proposed system by integrating a blood oximeter1,2, system chip, stimulus module, communication module, and memory module to monitor and record the user's blood oxygen level while sleeping. If the system detects that sleep-disorder related breathing occurs, the system will immediately cause the stimulus module to change the patient sleeping posture and improve her/his respiratory pattern3,4. Figure 1 shows a block diagram of the proposed system. We also compare four indices5 for automatically detecting sleep apnea events, develop an improved detection index using the optimization of thresholds, and illustrate the performance of the improved method. Results & Discussion Table 1 lists the performance of five indices for OSAS detection by using the blood oxygen signals of 554 patients who had received an overnight polysomnography test because they had been diagnosed with clinical symptoms or experienced screening for OSAS. The results show that the improved oxygen desaturation index's (ODI) correlation is 0.75 and stands between the measured AHI (apnea-hypoapnea index) and the predicted AHI; its performance is better than other indices employed in previous studies1,2,5. For patients with sleep disorders related to breathing, it can be an effective, lower-cost, and convenient way to improve the sleep quality. The system's design also features a long-term continuous record of oxygenation status allowing calculating AHI. It can simplify the traditional, time-consuming, and costly polysomnography testing process, and could help provide supplementary information for sleep therapy units. pubtype: Academic Journal doctype: abstract proceedings research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
