AbstractObjective：Toinvestigate theefectof non-contact slep monitoringusing milimeter-waveradarfordetectingsleepapnea events.Methods：A sleep monitoring model with a 6O-64GHz frequency-modulated continuous wave（FMCW）radar and an algorithm platform was established.Atotal of sixpatients diagnosedwithobstructive sleepapnea（OSA）whoreceivedtreatment China-JapanFrendshipHospitalfromMarchtoJune，2O24 wereincludedinthiscinicalobservationalstudy.Themillimeter-wave radarwas positioned5Ocmabovethepatients’anteriorchest inahorizontalorientationandpolysomnographywasusedtomonitor thepatientsthroughout thenighttocolectslepdataatthesame time.ClinicalinformationanddataoftheMedicalOutcomes Study Sleep Scale（MOS-SS，Chinese version）werecolectedandanalyzed.Resultsfromthemillmeter-waveradar and polysomnographywerecomparedandanalyzed.Results：The main symptoms of the six patients were noctural snoring orsuffcation，and mostof thepatientssuffredfromhigherBMIscore，rhadahistoryofexposure totoxicsubstances，hypertension，drugorfoodallergies，oraloholconsumption.The MOS-SSresultsindicated thatOSAcouldleadtosleepdisturbances，afecting patients'sleep qualityanddaytimecognitivefunction.Underthesleepmonitoring testmodelsystem，theFMCWradar'smonitoringeffciencyfor apnea events was 52.21% ，with an average reduction in chest wall mobility of 38.92% . However，the monitoring efficiency for hypopnea events was 45.96% ，with an average reduction in chest wall mobility of 33.61% . Conclusion ： The monitoring efficiency of FMCW Millimeter-wave Radar for apnea and hypopnea events was respectively 52.21% and 45.96% ，and it has a certain

effect in monitoring sleep apnea events.

阻塞性睡眠呼吸暫停（Obstructive Sleep Apnea，OSA），又稱為阻塞性睡眠呼吸暫停-低通氣綜合征，是一種因睡眠中上氣道反復(fù)塌陷導(dǎo)致的慢性疾病，表現(xiàn)為夜間打鼾、憋醒、睡眠結(jié)構(gòu)紊亂及日間嗜睡等[1]。（剩余7046字）
