Sleep assessment method and device

Abstract

The embodiment of the invention provides sleep evaluation method and device. The method is applied to sleep monitoring equipment. The sleep monitoring device is provided with a collection device usedfor collecting original signals of sleep quality of a monitored object. The method comprises the steps that the original signals collected by the collection device are obtained, wherein the original signals are preprocessed to obtain the sleep state and physical sign parameters of the monitored object; envelope extraction is carried out on the original signal in the evaluation window according tothe sleep state, and a maximum variance and a minimum variance in the evaluation window are calculated; determining a preset mapping table corresponding to the normalized variance according to the maximum variance and the minimum variance; and according to the preset mapping table, obtaining the monitoring times of the equivalent respiratory event corresponding to the normalized variance. According to the embodiment of the invention, the problem that the PSG is time-consuming, labor-consuming, high in professional threshold and the like in the prior art is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a sleep assessment method and device. Background technique [0002] As people pay more and more attention to sleep, sleep medicine has become a new hot spot in clinical medicine. Modern medical research has shown that the etiology of many diseases in the human body, especially cardiovascular and cerebrovascular diseases, is closely related to the patient's sleep quality, such as Sleep Apnea Hypopnea Syndrome (SAS), including central SAS, obstructive type SAS and the hybrid SAS that is both. Specifically, patients with SAS usually suffer from repeated respiratory airflow drops or stops due to upper airway obstruction or collapse during sleep, preventing oxygen from entering the lungs so that exhaust gases such as carbon dioxide in the body cannot be discharged, resulting in hypoxia and blood loss in the human body. The content of carbon dioxide...
