Abstract

The invention discloses a sleep apnea detection method and device based on a difference visible graph. The method comprises the following steps: acquiring signal data of a user in a sleep state, and extracting an interval sequence; performing coarse graining processing on the interval sequence to obtain a coarse-grained interval sequence; carrying out mapping of a visible graph and a horizontal visible graph on the interval sequence after coarse graining to obtain a difference visible graph and a node degree sequence corresponding to the difference visible graph; and calculating the mean value and the Shannon entropy of the node degree sequence, and detecting sleep apnea according to a calculation result. The device comprises a memory and a processor used for executing the sleep apnea detection method based on the difference visibility graph. By using the sleep apnea detection method, the accuracy of sleep apnea detection can be improved, and the robustness is high. The sleep apnea detection method and device based on the difference visible graph can be widely applied to the field of medical detection.

Description

technical field [0001] The invention relates to the field of medical detection, in particular to a sleep apnea detection method and device based on a difference visible map. Background technique [0002] Sleep apnea syndrome (SAS) affects a wide range, especially in my country, where about 66 million people suffer from this disease, which seriously endangers people's lives and increases social burden. Sleep apnea can easily lead to an increased incidence of various diseases, such as memory loss, Alzheimer's disease, cardiovascular disease and diabetes. Therefore, timely diagnosis of sleep apnea is of great significance. The current standard for sleep detection is polysomnography, which greatly disturbs the sleep of the subjects and is costly. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a sleep apnea detection method and device based on the difference visible map, which is simple, acc...
