Lokhu ukuhlola kwangempela okuvela kukhasimende e-Amazon.

Siyazi ukuthi i-SpO₂ iyipharamitha ebalulekile ebonisa umsebenzi wokuphefumula womzimba nokuthi okuqukethwe komoyampilo kujwayelekile yini, futhi i-oximeter iyithuluzi eliqapha isimo se-oxygen egazini emzimbeni wethu. I-oksijeni iyisisekelo semisebenzi yokuphila, i-hypoxia iyimbangela yezifo eziningi, futhi izifo eziningi nazo zingabangela ukutholakala komoya-mpilo okwanele. I-SpO₂ngaphansi kuka-95% iwukubonakaliswa kwe-hypoxia ethambile. Ngaphansi kuka-90% i-hypoxia eyingozi futhi idinga ukwelashwa ngokushesha ngangokunokwenzeka. Akubona kuphela abantu asebekhulile abathambekele ku-hypoxemia, kodwa abantu banamuhla banokucindezeleka okukhulu kwengqondo nomsebenzi kanye nesikhathi sokuphumula. Ukungahambi kahle ngokuvamile kuholela ku-hypoxemia. I-SpO₂ ephansi yesikhathi eside izodala umonakalo omkhulu emzimbeni womuntu. Ngakho-ke, kuyadingeka ukukala i-SpO₂ emzimbeni njalo, ngisho noma izinyathelo zokuzivikela zithathwa.

Uma kuziwa kuma-oximeters, kubasebenzisi besitayela sasekhaya kanye nochwepheshe bokuqina komzimba, abantu abaningi bazokhetha ama-oximeter aphathwayo ane-clamp-clamp, ngoba mahle, ahlangene, aphathwa kalula, futhi awanqunyelwe isikhathi nendawo. Kulula kakhulu futhi kuyashesha. Ama-oximeter okunamathisela umunwe nawo asetshenziswa ezindaweni eziningi zezokwelapha, kodwa izidingo zokunemba ziphezulu uma kuqhathaniswa. Ngakho-ke, ukuqedwa kwamaphutha kungenye yezinto ezibalulekile zokulinganisa okuqinile kwe-oximeter.

Ukunemba kwe-oximeter kuhlobene eduze nomgomo wezobuchwepheshe we-oximeter. Izimiso zokuklama zabahlinzeki bezixazululo ze-oximeter zamanje emakethe ziyafana ngokuyisisekelo: ukusetshenziswa kwe-LED ebomvu, i-infrared LED kanye nokwakheka kwe-photodiode yesekethe yenzwa ye-SpO₂, Kanye nesekethe ye-LED drive. Ngemva kokuba ukukhanya okubomvu nokukhanya kwe-infrared kudluliselwa ngomunwe, kutholwa yisekethe yokucubungula isignali, bese kudluliswa kumojula ye-ADC ye-single-chip microcomputer ukuze kuqhutshekwe nokubala iphesenti le-SpO₂. Zonke zisebenzisa izinto ezizwela ukukhanya ezifana nokukhanya okubomvu, ukukhanya kwe-infrared LED ne-photodiode ukuze kulinganiswe ukudluliswa kweminwe nezindlebe. Kodwa-ke, abahlinzeki bezixazululo ze-oximeter abanamazinga aphezulu kanye nezidingo zohlelo banezidingo zokuhlola eziqinile nezifuna kakhulu. Ngokungeziwe ezindleleni zokuhlola ezijwayelekile ezishiwo ngenhla, kufanele basebenzise imikhiqizo yabo yohlelo kanye nokulingiswa kwe-oximeter kochwepheshe. Idatha iqhathaniswa ne-oximeter yebanga lezokwelapha.

I-oximeter eyakhiwe yi-MedLinket iye yacwaningwa ngokomtholampilo ezibhedlela eziqeqeshiwe. Ocwaningweni olulawulwayo lokugcwala kwendawo, i-SaO₂ yebanga lokulinganisa lomkhiqizo elingu-70% ukuya ku-100% liqinisekisiwe. Uma kuqhathaniswa nevelu ye-SpO₂ ye-arterial elinganiswa nge-CO-Oximeter, kutholwa idatha enembile. Iphutha le-SpO₂ lilawulwa ku-2%, futhi iphutha lokushisa lilawulwa ku-0.1℃, elingafinyelela isilinganiso esinembile se-SpO₂, izinga lokushisa, ne-pulse. , Ukuze kuhlangatshezwane nezidingo zokulinganisa kochwepheshe.

Ukukhetha isisombululo se-oximeter se-MedLinket esingabizi futhi esinembile emakethe, ngikholwa ukuthi izothola umusa wabasebenzisi ngokushesha.
