Isu tinoziva kuti SpO₂ iparameter yakakosha inoratidza kushanda kwekufema kwemuviri uye kana iyo okisijeni yemukati yakajairwa, uye oximeter mudziyo unotarisisa mamiriro eokisijeni yeropa mumuviri wedu. Okisijeni ndiyo hwaro hwemabasa ehupenyu, hypoxia ndiyo honzeri yezvirwere zvakawanda, uye zvirwere zvakawanda zvinogona kukonzera kusakwana kweokisijeni. SpO₂pasi pe95% chiratidzo che hypoxia yakapfava. Isingasviki 90% is a serious hypoxia uye inoda kurapwa nekukurumidza sezvinobvira. Havasi vakwegura chete vane hypoxemia, asi vanhu vemazuva ano vane zvakawanda zvekunetseka mupfungwa uye basa uye nguva yekuzorora. Zvisizvo zvinowanzokonzera hypoxemia. Yenguva refu yakaderera SpO₂ ichakonzera kukuvadza kwakakomba kumuviri wemunhu. Saka, zvakakosha kuyera SpO₂ mumuviri nguva dzose, kunyange kana matanho ekudzivirira achitorwa.

Kana zvasvika kune oximeters, yevashandisi vekumba uye nyanzvi dzekusimba, vanhu vazhinji vanosarudza zvigunwe-clamp inotakurika oximeters, nekuti yakanakisa, compact, nyore kutakura, uye haina kuganhurirwa nenguva nenzvimbo. Yakanaka kwazvo uye inokurumidza. Finger clip oximeters inoshandiswawo munzvimbo dzakawanda dzehunyanzvi dzekurapa, asi izvo zvinodikanwa zvakati wandei. Naizvozvo, kubviswa kwezvikanganiso chimwe chezvinhu zvakakosha zvekuyerwa kwakasimba kweiyo oximeter.

Kurongeka kweiyo oximeter kunoenderana zvakanyanya nehunyanzvi hwehunyanzvi musimboti weiyo oximeter. Misimboti yedhizaini yeazvino oximeter mhinduro vanopa pamusika vakafanana: kushandiswa kweiyo tsvuku LED, infrared LED uye photodiode kuumbwa kweSpO₂ sensor circuit, Plus iyo LED drive circuit. Mushure mekunge mwenje dzvuku uye mwenje we infrared zvichifambiswa nemunwe, zvinoonekwa nechiratidzo chekugadzirisa dunhu, uye zvobva zvapfuudzwa kuADC module ye single-chip microcomputer kuti iwedzere kuverenga chikamu cheSpO₂. Vese vanoshandisa zvinhu zvakapfava semwenje dzvuku, infrared mwenje LED uye photodiode kuyera kutapurirana kweminwe uye nzeve. Nekudaro, oximeter mhinduro vanopa vane yakakwira zviyero uye zvinodiwa zvechirongwa vane zvakaomarara uye zvakanyanya kudiwa bvunzo zvinodiwa. Pamusoro peyakajairwa bvunzo nzira dzataurwa pamusoro, ivo vanofanirwa kushandisa yavo yechirongwa zvigadzirwa uye nyanzvi oximeter simulations. Iyo data inofananidzwa neyekurapa-giredhi oximeter.

Iyo oximeter yakagadziridzwa neMedLinket yakadzidzwa muzvipatara zvine hunyanzvi. Muchidzidzo chakadzorwa chekuzara, iyo SaO₂ yechiyero chechigadzirwa ichi ye70% kusvika 100% yakasimbiswa. Kuenzaniswa neiyo arterial SpO₂ kukosha yakayerwa neCO-Oximeter, data chaiyo inowanikwa. Iko kukanganisa kweSpO₂ kunodzorwa pa2%, uye kukanganisa kwekushisa kunodzorwa pa 0.1 ℃, iyo inogona kuwana kuyerwa kwakaringana kweSpO₂, tembiricha, uye pulse. , Kusangana nezvinodiwa zvekuyera kwehunyanzvi.

Kusarudza MedLinket inodhura-inoshanda uye yakaringana kuyerwa oximeter mhinduro mumusika, ndinotenda ichakurumidza kuwana nyasha dzevashandisi.
