摘要:The diagnosis of sleep apnea is mainly based on polysomnographic system and the diagnostic process is time-consuming, complicated and uncomfortable. It is an urgent need to make the diagnosis process convenient and comfortable. In this paper, we compared finger photoplethysmographic (PPG) signals of healthy and sleep apnea patients in five sleep stages by Gaussian function. PPG signals were obtained by polysomnographic system from 17 healthy subjects and 70 sleep apnea patients in Shandong Provincial Hospital. The 10 successive cardiac cycles signal, which did not include the sleep apnea events, was intercepted and normalized during each sleep stage. Each data segment was fitted by three Gaussian functions and obtained a total of 9 parameters for 3 functions (each function has 3 parameters). As for the healthy, means of 9 Gaussian parameters in 5 sleep stages were compared respectively and means for patients were treated similarly. Gaussian parameters of healthy were also compared with those of sleep apnea patients in 5 sleep stages respectively. The results showed there were no significant statistical differences among 5 sleep stages within healthy group or patient group, but there were significant statistical differences among healthy patients and sleep apnea patients in 5 sleep stages for Gaussian parameters W-1, W-3 and C-1. This study could be an easy operated and comfort way to diagnose sleep apnea.
