Polysomnography device, system and method for apnea

Abstract

The invention discloses a polysomnography device, system and method for apnea. The device comprises a blood oxygen judgment module, an apnea type judgment module and a body position judgment module; the blood oxygen judgment module is configured to preliminarily judge apnea by polysomnography according to the blood oxygen saturation and a saturation threshold value; the apnea type judgment module is configured to obtain a thoracico-abdominal fluctuating oscillogram when obtaining the preliminary judgment result of breathing abnormality, and obtaining a breathing abnormality judgment result of obstructive sleep apnea or central sleep apnea according to comparison of the thoracico-abdominal fluctuating oscillogram and a normal breathing oscillogram; and the body position judgment module is configured to obtain body position information according to the pressed state of each part of a human body if the obstructive sleep apnea occurs, and judge whether the obstructive sleep apnea occurs or not according to the correlation between the body position information and the oxyhemoglobin saturation. According to the device, system and method, the judgment accuracy is improved, the traditional sleep polysomnography method is simplified, the problem of insufficient diagnosis rate due to too high cost is solved, and the problem of detection data deviation caused by too many detection instruments and strange environment is reduced.

Description

technical field [0001] The invention relates to the technical field of sleep apnea monitoring equipment, in particular to a polysomnography sleep apnea monitoring device, system and method. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Sleep apnea (SA) refers to the cessation of respiratory airflow through the mouth and nose during sleep for more than 10 seconds, and hypopnea refers to the reduction of respiratory airflow intensity (amplitude) by more than 50% compared with the baseline level during sleep, accompanied by arterial blood oxygen saturation ( SaO 2 ) decreased by ≥ 4% from the base level. Clinically, sleep apnea syndrome is divided into central (CSA), obstructive (OSA), and mixed (MSA) according to the movement of the chest and abdomen during apnea during sleep. Most of the sleep apnea syndromes (it can be said that more ...

Problems solved by technology

[0010] In order to solve the above problems, the present invention proposes a polysomnography sleep apnea monitoring device, system and method, which comprehensively analyze the type of sleep apnea through the double detection mode of chest and abdomen fluctuations and blood oxygen saturation, and improve the accuracy of judgment. Accuracy; Simplify the traditional sleep polygraphy detection method with low data utilization rate, without the need for a professional sleep laboratory, solve the problem of high cost and insufficient diagnosis rate, and reduce the risk caused by too many detection instruments and unfamiliar environment The sleep data is abnormal, and the problem of detecting data deviation
