This　paper　presents　an　OSA　patient　interactive　monitoring　system　based　on　the　Beidou　system.　This　system　allows　OSA　patients　to　get　timely　rescue　when　they　become　sleepy　outside.　Because　the　Beidou　position　marker　has　an　interactive　function,　it　can　reduce　the　anxiety　of　the　patient　while　waiting　for　the　rescue.　At　the　same　time,　if　a　friend　helps　the　OSA　patients　to　call　the　doctor,　the　friend　can　also　report　the　patient＇s　condition　in　time.　This　system　uses　the　popular　IoT　framework.　At　the　bottom　is　the　data　acquisition　layer,　which　uses　wearable　sensors　to　collect　vital　signs　from　patients,　with　a　focus　on　ECG　and　SpO2　signals.　The　middle　layer　is　the　network　layer　that　transmits　the　collected　physiological　signals　to　the　Beidou　indicator　using　the　Bluetooth　Low　Energy　(BLE)　protocol.　The　top　layer　is　the　application　layer,　and　the　application　layer　uses　the　mature　rescue　interactive　platform　of　Beidou.　The　Beidou　system　was　developed　by　China　itself,　the　main　coverage　of　the　satellite　is　in　Asia,　and　is　equipped　with　a　high-density　ground-based　augmentation　system.　Therefore,　the　Beidou　model　improves　the　positioning　accuracy　and　is　equipped　with　a　special　communication　satellite,　which　increases　the　short　message　interaction　function.　Therefore,　patients　can　report　disease　progression　in　time　while　waiting　for　a　rescue.　After　our　simulation　test,　the　effectiveness　of　the　OSA　patient　rescue　monitoring　system　based　on　the　Beidou　system　and　the　positioning　accuracy　of　OSA　patients　have　been　greatly　improved.　Especially　when　OSA　patients　work　outdoors,　the　cell　phone　base　station　signal　coverage　is　relatively　weak.　The　satellite　signal　is　well-covered,　plus　the　SMS　function　of　the　Beidou　indicator.　Therefore,　the　system　can　be　used　to　provide　timely　patient　progress　and　provide　data　support　for　the　medical　rescue　team　to　provide　a　more　accurate　rescue　plan.　After　a　comparative　trial,　the　rescue　rate　of　OSA　patients　using　the　detection　device　of　this　system　was　increased　by　15　percentage　points　compared　with　the　rescue　rate　using　only　GPS　satellite　phones.
