Lokhu kuwukuhlola kwangempela okuvela kumakhasimende ku-Amazon.

Siyazi ukuthi i-SpO₂ iyipharamitha ebalulekile ekhombisa umsebenzi wokuphefumula komzimba nokuthi okuqukethwe yi-oxygen kujwayelekile yini, kanti i-oximeter iyithuluzi eliqapha isimo se-oxygen egazini emzimbeni wethu. I-oxygen iyisisekelo semisebenzi yokuphila, i-hypoxia iyimbangela yezifo eziningi, futhi izifo eziningi zingabangela nokuntuleka kokunikezwa kwe-oxygen. I-SpO₂engaphansi kuka-95% iyisibonakaliso se-hypoxia encane. Ngaphansi kuka-90% yi-hypoxia enkulu futhi idinga ukwelashwa ngokushesha okukhulu. Akubona asebekhulile kuphela abathambekele ekuncipheni kwe-hypoxemia, kodwa nabantu banamuhla banengcindezi enkulu yengqondo kanye nesikhathi sokusebenza kanye nokuphumula. Ukungajwayelekile kuvame ukuholela ekuncipheni kwe-hypoxemia. I-SpO₂ephansi yesikhathi eside izobangela umonakalo omkhulu emzimbeni womuntu. Ngakho-ke, kubalulekile ukukala i-SpO₂ emzimbeni njalo, noma ngabe kuthathwa izinyathelo zokuzivikela.

Uma kukhulunywa ngama-oximeter, kubasebenzisi besitayela sasekhaya kanye nochwepheshe bokuzivocavoca abangochwepheshe, abantu abaningi bazokhetha ama-oximeter aphathekayo ane-finger-clamp, ngoba amahle kakhulu, acinene, kulula ukuwaphatha, futhi awanqunyelwe yisikhathi nendawo. Kulula kakhulu futhi kuyashesha. Ama-oximeter e-finger clip nawo asetshenziswa ezindaweni eziningi zezokwelapha zobungcweti, kodwa izidingo zokunemba ziphakeme kakhulu. Ngakho-ke, ukuqedwa kwamaphutha kungenye yezinto ezibalulekile zokulinganisa okuqinile kwe-oximeter.

Ukunemba kwe-oximeter kuhlobene kakhulu nomgomo wobuchwepheshe wobungcweti we-oximeter. Izimiso zokuklama zabahlinzeki bezixazululo ze-oximeter zamanje emakethe ziyafana ngokuyisisekelo: ukusetshenziswa kwe-LED ebomvu, i-infrared LED kanye nokwakheka kwe-photodiode kwesekethe yesenzwa ye-SpO₂, kanye nesekethe ye-LED drive. Ngemva kokuba ukukhanya okubomvu kanye nokukhanya kwe-infrared kudluliswe ngomunwe, kutholwa yisekethe yokucubungula isignali, bese kudluliselwa kumojuli we-ADC we-single-chip microcomputer ukuze kubalwe kabanzi iphesenti le-SpO₂. Bonke basebenzisa izinto ezizwela ukukhanya njengokukhanya okubomvu, ukukhanya kwe-infrared LED kanye ne-photodiode ukukala ukudluliswa kweminwe nama-earlobes. Kodwa-ke, abahlinzeki bezixazululo ze-oximeter abanezindinganiso eziphakeme nezidingo zohlelo banezidingo zokuhlola eziqinile nezidinga kakhulu. Ngaphezu kwezindlela zokuhlola ezivamile okukhulunywe ngazo ngenhla, kumele basebenzise imikhiqizo yabo yohlelo kanye nokulingisa kobuchwepheshe be-oximeter. Idatha iqhathaniswa ne-oximeter yezinga lezokwelapha.

I-oximeter ethuthukiswe yi-MedLinket ihlolwe ngokwezokwelapha ezibhedlela ezifanelekile. Esifundweni sokugcwala okulawulwayo, i-SaO₂ yobubanzi bokulinganisa balo mkhiqizo obungu-70% kuya ku-100% iqinisekisiwe. Uma kuqhathaniswa nenani le-SpO₂ ye-arterial elilinganiswe yi-CO-Oximeter, kutholakala idatha enembile. Iphutha le-SpO₂ lilawulwa ku-2%, kanti iphutha lokushisa lilawulwa ku-0.1℃, okungafinyelela ukulinganiswa okunembile kwe-SpO₂, izinga lokushisa, kanye ne-pulse. , Ukuze kuhlangatshezwane nezidingo zokulinganisa kochwepheshe.

Ngikhetha isixazululo se-oximeter sokulinganisa esingabizi futhi esinembile se-MedLinket emakethe, ngikholwa ukuthi sizothandwa abasebenzisi ngokushesha.
