OSA Patient Monitoring Based on the Beidou System [PDF]
Frontiers in Public Health, 2021 This paper presents an OSA patient interactive monitoring system based on the Beidou system. This system allows OSA patients to get timely rescue when they become sleepy outside. Because the Beidou position marker has an interactive function, it can reduce the anxiety of the patient while waiting for the rescue.
