A Clinical Validation Study on the Assessment of Sleep Apnea by Smart Watch and Smartphone

OSA is common frequently-occurring disease, in the general population prevalence of 9% to 38%[2] (in apnea hypoventilation index (AHI) 5 for the standard or higher). A OSA, according to the global burden of global nearly 1 billion patients with OSA, and our country is, the most populous country[3] in the OSA sick: on the basis of AHI 5 or more, China has 176 million OSA crowd; With AHI ≥15 as the standard, China has 66 million people with OSA. Although the high prevalence of OSA, diagnostic rate was very low, a study shows there are now about 90% of undiagnosed[4] OSA. The serious influence the diagnosis and treatment of OSA and downstream disease prevention and control.

There are many reasons for the low diagnosis rate of OSA. About the danger of OSA patients with insufficient understanding and OSA diagnosis treatment process link is the more important reason. The OSA diagnosis depends on the patient to the hospital, after outpatient service initiated or portable polysomnography evaluation, limited by registered, see a doctor, make an appointment, monitoring, and many other processes, as well as the level of understanding of OSA patients, many patients with OSA don't want to come to the hospital. With the popularity of intelligent wearable devices, intelligent wearable device can effectively monitor the human multiple physiological indicators, and has high comfort, the cost is low, the detection process is not restricted by time and place, etc. Besides smartphones by smart sensors, collect the snoring, heart shock signals (BCG) and respiratory, physiological parameters, such as non-contact multi-parameter sleep monitoring technology, made possible by the. These are the home sleep monitoring way to provide more convenient and easy to use, makes the risk of OSA screening more convenient[5-8].

The purpose of this study is to evaluate the diagnostic value of smartphones and watches for OSA screening. The study will be conducted in individuals suspected of having OSA. Subjects will undergo "gold standard" PSG assessment (overnight polysomnography with staff supervision) in a sleep monitoring room, while wearing a smartwatch and smartphone for monitoring. The results will be compared to evaluate the diagnostic value of smartwatches and smartphones for OSA.
