A method for classifying snoring

Abstract

The invention provides a snore parting method which comprises the following steps: S1, acquiring snore of a monitored person before, during and after a breathing disorder event, wherein the breathing disorder event comprises hypopnea, apnoea and respiratory effort related arousal; S2, uploading the breathing disorder event in the step S1 to a processing device, and dividing the snore types according to a time relationship between the snore and breathing disorder event. The snore types in the processing device comprise snore in a respiratory cycle before hypopnea, snore during hypopnea, snore in a respiratory cycle after hypopnea, snore in a respiratory cycle before apnoea, snore during apnoea, snore in a respiratory cycle after apnoea, and the like. According to the parting method provided by the invention, the snore and the breathing disorder event can be subjected to internal relation in real time, the snore information is fully utilized, and the information accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, and more specifically relates to a snore typing method. Background technique [0002] Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) refers to repeated collapse and obstruction of the upper airway during sleep, causing sleep apnea, hypoventilation, recurrent sleep structure disorder, and pathological sleep interruption. A series of pathological changes secondary to the body can lead to the occurrence of various complications such as cardiovascular disease, cognitive decline, stroke and type 2 diabetes. More importantly, it is an important cause of the aggravation, refractory and death of these diseases. At the same time, OSAHS is a sleep-breathing disease with potential sudden nocturnal death, which seriously affects the quality of life and longevity of patients. [0003] Polysomography (PSG) is the gold standard for diagnosing OSAHS, but unfortunately, PSG requires patients to wear masks, c...

Based on the internationally accepted definition that "no respiratory disorder after snoring is called simple snoring", our previous research centered on snoring, and classified snoring patients into There are four types of snoring throughout the night, but there are certain flaws in this study: snoring is only classified according to the number of respiratory disturbances after snoring, ignoring the internal relationship between snoring and respiratory disturbances, that is, is snoring followed by apnea or hypopnea? Some studies have shown that there is no significant difference in the acoustic characteristics of snoring before and after apnea, but the snoring before, during, and after apnea, hypopnea, and respiratory effort-related micro-awakening are ignored, so the snoring information research in this area has not been used
