The apnea detection module transmits the breath signal to the apnea detection module. The apnea detection module is configured by the user''s smartphone. The apnea detection module determines sleep apnea and hypoventilation from the received respiration signal, To a sleep apnea monitoring system in which a sleeping apnea occurrence frequency is used to determine a danger and a warning signal is output to a guardian''s smartphone when the person is in a dangerous state. The sleep apnea monitoring system of the present invention is equipped with or attached to a persistent positive pressure retainer and includes a respiratory detection unit that detects the nasal airflow of a subject as a breathing signal； And an arithmetic processing unit for wirelessly receiving the respiration signal detected from the respiration detection unit and detecting an apnea interval, a low respiration interval, and an apnea interval occurrence count in the received respiration signal, The arithmetic processing unit performs a preprocessing for removing high frequency noise and baseline variation from the respiration signal received from the respiration detection unit and outputs a respiration signal having a maximum value as a peak in a respiration signal of a predetermined maximum threshold value or more among the preprocessed respiration signals, And a respiration signal having a minimum value in a respiration signal below a predetermined minimum threshold is detected as a trough point and the value of the peak point and the trough point at the subsequent peak point and trough point And the difference between the values is obtained as the amplitude of the respiratory cycle.본 발명은, 지속양압 유지기로부터 호흡신호를 무호흡 검출모듈로 전송하되, 무호흡 검출모듈은 사용자의 스마트폰으로 이루어지며, 무호흡 검출모듈은 수신된 호흡신호로부터 수면 무호흡, 저호흡 여부를 판단하고, 수면 무호흡 발생빈도를 이용하여 위험여부를 판단하여, 위험상태일 경우 보호자의 스마트폰으로 위급상황 알림신호를 출력하게 하는, 보호자 스마트폰과 연동되는 수면무호흡상태 모니터링 시스템에 관한 것이다.본 발명의 수면무호흡상태 모니터링 시스템은, 지속양압 유지기에 구비되거나 장착되며, 피검자의 비강의 기류를 호흡신호로서 검출하는, 호흡 검출부； 호흡 검출부로부터 검
