Sleep breathing disorder monitoring method and system thereof

Abstract

The invention provides a sleep breathing disorder monitoring method and a system thereof. The sleep breathing disorder monitoring method comprises the following steps of: obtaining body vibration dataof a human body in a sleep state for a preset duration, and carrying out filtering treatment on the body vibration data of the preset duration, and obtaining breathing waveform data of the preset duration; acquiring an envelope line of the preset duration based on the breathing waveform data of the preset duration; and comparing the envelope line of the preset duration with a breathing disorder threshold, and determining whether sleep breathing disorder exists or not based on a comparison result. The sleep breathing disorder monitoring system can realize monitoring and early warning of sleepbreathing disorder by using an unconstrained non-contact vibration sensor, and is simpler to operate and lower in cost compared with a multi-guide sleep monitoring system, so that breathing of a userduring sleep can be effectively monitored for a long time, and an auxiliary means is provided for the user to go to a medical institution for definite diagnosis.

Description

technical field [0001] The present invention relates to the technical field of signal processing, and more specifically, to a method and system for monitoring sleep-disordered breathing. Background technique [0002] With the development of science and technology, people pay more and more attention to the physiological and pathological conditions of sleep. Sleep medicine, as an important part of modern medicine, has also attracted much attention. Among them, sleep apnea is a serious sleep disease caused by repeated and long-term breathing stop, which leads to interruption of sleep continuity or short-term reduction of blood oxygen content and increase of carbon dioxide content. Sleep apnea is generally divided into the following three categories: 1. Obstructive sleep apnea, which is the most common type, is caused by repeated pharynx and upper airway closures during sleep. However, chest and abdomen movements still exist; 2. Central sleep apnea, this type is relatively rare...

Problems solved by technology

However, polysomnography has disadvantages such as expensive, difficult to operate and difficult to popularize and use.

In addition, the use of polysomnography requires electrodes to be attached to the patient's body to complete the monitoring, which will affect the patient's sleep and cause the monitoring results to be inaccurate
