Lokhu ukuhlola kwangempela okuvela kukhasimende e-Amazon.
Siyazi ukuthi i-SpO2 iyipharamitha ebalulekile ebonisa ukusebenza kokuphefumula komzimba kanye 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-SpO2 ngaphansi 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-oximeter, kubasebenzisi besitayela sasekhaya kanye nezingcweti zokuqina 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: 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 izakhi ezizwela ukukhanya ezifana nokukhanya okubomvu, ukukhanya kwe-infrared LED kanye ne-photodiode ukukala 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 yafundwa emtholampilo ezibhedlela eziqeqeshiwe.Ocwaningweni olulawulwayo lokugcwala kwendawo, i-SaO2 yebanga lokulinganisa lomkhiqizo elingu-70% kuya ku-100% liqinisekisiwe.Uma kuqhathaniswa nenani le-arterial SpO2 elilinganiswa 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, ngikholelwa ukuthi sizothola umusa wabasebenzisi ngokushesha.
