Early warning detection system for sleep apnea sudden death

Abstract

The invention relates to an early warning detection system for sleep apnea sudden death. The system is characterized by comprising a pulse blood oxygen signal collecting device, a data processor and adisplay and transmitting device. According to the invention, a sudden death risk level is judged by monitoring changes of pulse and the value of blood oxygen saturation degree of a patient in sleeping all night and performing analysis and comparison with a sudden death risk module built in the data processor, sleeping monitoring information containing the judgement result of the sudden death risklevel is transmitted to the display and transmitting device for display, alarm signals and warning sounds are sent out when a sudden death high risk is monitored, and the display and transmitting device can transmit the sleeping monitoring information to a computer, a mobile phone, a cloud or other associated equipment, so as to realize instant sudden death risk early warning and alarm. The invention provides a practical and effective early warning detection system for prevention of the occurrence of sudden death in sleeping of patients with sleep apnea syndrome.

Description

technical field [0001] The invention relates to a sleep apnea sudden death early warning detection system, which belongs to the field of sleep monitoring medical equipment. Background technique [0002] Sleep apnea syndrome is a common sleep-disordered breathing disease, manifested as sleep apnea, snoring and other symptoms. Mostly due to the collapse of the upper airway tissue, resulting in blockage of the airway. During apnea, the blood oxygen saturation drops and the heart rate slows down. As breathing resumes, the blood oxygen saturation rises and the heart rate becomes faster. The longer the apnea lasts, the greater the drop in blood oxygen saturation and the more severe the arrhythmia. If the apnea is prolonged, sudden death may occur. Severe hypoxemia and arrhythmia are clinical signs before sudden death in sleep apnea syndrome. For patients with sleep apnea syndrome, the risk of sudden death is very high. Dozens or hundreds of apneas occur during the patient's sl...

Problems solved by technology

[0003] PSG polysomnography system and home sleep monitor are currently used for clinical diagnosis. The monitoring parameters include EEG, oculogram, mandibular myoelectricity, mouth and nose airflow and respiratory movement, ECG, blood oxygen, snoring, extremity Movement, body position, etc., but these sleep monitoring devices have no early warning of the risk of sudden death from sleep apnea syndrome
