The study provides an overview of the development status of sleep disorder monitoring devices.Currently,polysomnography(PSG)is the gold standard for diagnosing sleep disorders,necessitating multiple leads and requiring overnight monitoring in a sleep laboratory,which can be cumbersome for patients.Nevertheless,the performance of PSG has been enhanced through research on sleep disorder monitoring and sleep staging optimization.An alternative device is the home sleep apnea testing(HSAT),which enables patients to monitor their sleep at home.However,HSAT does not attain the same level of accuracy in sleep staging as PSG,rendering it inappropriate for screening individuals with asymptomatic or mild obstructive sleep apnea-hypopnea syndrome(OSAHS).The study suggests that establishing a Chinese sleep staging database and developing home sleep disorder monitoring devices that can serve as alternatives to PSG will represent a future development direction.
