Tinoziva kuti SpO₂ chinhu chakakosha chinoratidza mashandiro emuviri ekufema uye kana huwandu hweokisijeni huri hwakanaka, uye oximeter chishandiso chinoongorora mamiriro eokisijeni muropa mumuviri wedu. Okisijeni ndiyo hwaro hwezviitiko zvehupenyu, hypoxia ndiyo honzeri yezvirwere zvakawanda, uye zvirwere zvakawanda zvinogonawo kukonzera kusakwana kweokisijeni. SpO₂iri pasi pe95% chiratidzo chehypoxia iri nyore. Pasi pe90% hypoxia yakakomba uye inoda kurapwa nekukurumidza. Havasi vakwegura chete vanonyanya kubatwa nehypoxemia, asi vanhu vemazuva ano vane kushushikana kwepfungwa kwakawanda uye nguva yekushanda nekuzorora. Kusarongeka kunowanzo tungamira kuhypoxemia. SpO₂ yakaderera kwenguva refu inokonzera kukuvara kwakakomba mumuviri wemunhu. Saka, zvakakosha kuyera SpO₂ mumuviri nguva dzose, kunyangwe matanho ekudzivirira akatorwa.

Kana zvasvika kune maoximeter, kune vanoshandisa imba uye nyanzvi dzekurovedza muviri, vanhu vazhinji vanosarudza maoximeter anotakurika ane chigunwe, nekuti akanaka kwazvo, madiki, ari nyore kutakura, uye haagumiri panguva nenzvimbo. Zviri nyore uye zvinokurumidza. Maoximeter echigunwe anoshandiswawo munzvimbo dzakawanda dzekurapa, asi zvinodiwa pakunyatsorongeka zvakanyanya. Saka, kubviswa kwezvikanganiso chimwe chezvinhu zvakakosha pakuyera kwakasimba kweoximeter.

Kururama kwe oximeter kwakabatana zvikuru nepfungwa yehunyanzvi ye oximeter. Nheyo dzekugadzira dzevapi vemhinduro dze oximeter dziripo pamusika dzakafanana: kushandiswa kwe LED dzvuku, infrared LED uye photodiode muSpO₂ sensor circuit, pamwe ne LED drive circuit. Mushure mekunge chiedza dzvuku ne infrared light zvatumirwa nemunwe, zvinoonekwa ne signal processing circuit, uye zvobva zvaendeswa kuADC module ye single-chip microcomputer kuti zviverengere huwandu hweSpO₂. Vese vanoshandisa zvinhu zvinonzwa chiedza zvakaita se red light, infrared light LED uye photodiode kuyera kutumirwa kweminwe nema earlobes. Zvisinei, vanopa mhinduro dze oximeter vane mwero wepamusoro uye zvinodiwa zvechirongwa vane zvinodiwa zvekuyedza zvakaoma uye zvinoda simba. Kuwedzera kune nzira dzekuedza dzataurwa pamusoro apa, vanofanirwa kushandisa zvigadzirwa zvavo zvepurogiramu uye simulations dzehunyanzvi dze oximeter. Data iri rinoenzaniswa ne oximeter yekurapa.

Oximeter yakagadzirwa neMedLinket yakaongororwa muzvipatara zvine hunyanzvi. Mukudzidza kwakadzorwa kwehuwandu hwemasero, SaO₂ yehuwandu hwekuyera kwechigadzirwa ichi hwe70% kusvika 100% yakasimbiswa. Zvichienzaniswa nehukuru hweSpO₂ hwearterial hwakayerwa neCO-Oximeter, data rakarurama rinowanikwa. Kukanganisa kweSpO₂ kunodzorwa pa2%, uye kukanganisa kwekupisa kunodzorwa pa0.1℃, izvo zvinogona kuyera SpO₂, tembiricha, uye pulse nemazvo. , Kuzadzisa zvinodiwa zvekuyera kwehunyanzvi.

Kusarudza mhinduro yeMedLinket inoshanda zvishoma uye yakarurama yekuyera oximeter pamusika, ndinotenda kuti ichakurumidza kufarirwa nevashandisi.
