Abasubathi abalwela ukuthola imiphumela yezinga eliphezulu futhi abafuna ukuzuza umsebenzi oncomekayo ezinhlosweni zabo ngokuzivivinya okukhulayo okuyinselelo ukuze baqhudelane futhi baqhwakele emqhudelwaneni.Kodwa-ke, ukuqapha imiphumela yokuzivocavoca kubalulekile kulokhu kulandelwa njengendlela yokuqinisekisa inqubekelaphambili nokuzuza impumelelo yesikhathi esizayo.
Ukuze uthuthukise imisebenzi yomzimba, ukukhulisa imisebenzi yamaphaphu kubaluleke kakhulu.I-Metabolism, umfutho wegazi nokusebenza kwemisipha konke kuncike emandleni amaphaphu okuletha umoya-mpilo kulo lonke uhlelo.
Ukuqinisekisa ukuthi amazinga komoyampilo ahlala ebangeni elijwayelekile kuzokhuphula futhi kuthuthukise ukujima.Ngokuthuthuka kwakamuva kwesayensi kanye nobuchwepheshe obuphambili ukuthola amazinga amancane okulinganisa okugcwala komoyampilo ngaphambi, phakathi nangemuva kokujima empeleni kulula futhi kusebenza kahle ngokusetshenziswa kwama-pulse oximeter ahlangene futhi anembile.
Amathuluzi okuxilonga afana nama-pulse oximeters ayisibonelo sedivayisi yezokwelapha esetshenziselwa ukukala izinga le-oxygen (noma ukugcwala komoyampilo, i-Sp02) ngaphakathi kwegazi.Ayina-invasive, ayinabuhlungu futhi isetshenziswa kabanzi emkhakheni wezokwelapha kanye nabantu abasebenza noma abaqeqesha ezindaweni eziphakeme basebenzisa amadivaysi.
Lapho umoya-mpilo udonselwa emaphashini futhi udlulela egazini, ingxenye enkulu yomoya-mpilo inamathela ku-hemoglobin (iphrotheni etholakala emangqamuzaneni abomvu egazi) bese ithuthelwa egazini.Uma lokhu sekwenzekile, igazi elinomoya-mpilo liyajikeleza futhi lihlakazeke ezicutshini.Uma umzimba ungawutholi umoya-mpilo owanele, khona-ke imizimba yethu ingaba nesimo esaziwa ngokuthi i-generalized hypoxia.Ngeshwa lokhu kungenzeka futhi ezimweni eziningi kubantu abaziqeqesha kanzima ngokomzimba.
Ubuchwepheshe be-finger pulse oximeter buncike ezintweni zokumunca ukukhanya kwe-hemoglobin kanye nemvelo eshayayo yokugeleza kwegazi ngaphakathi kwemithambo ukunquma ukugcwala komoyampilo, Sp02.
Ku-pulse oximeter, imithombo yokukhanya emibili (okubomvu ne-infrared) ikhanyisa ukukhanya ngomunwe nakumshini wokuthwebula izithombe ohlangothini olungemuva.Ngenxa yokuthi izixazululo ezimbili zokukhanya zimuncwa ngokuhlukile yi-deoxyhemoglobin ngaphezu kwe-oxyhemoglobin, ukuhlaziya isignali kuzovumela ukugcwala komoyampilo nokushaya kwenhliziyo ukuthi kukalwe.Ngokusho kodokotela izigaba ezijwayelekile ezamukelekayo zingasuka kumaphesenti angama-95, nakuba amanani ehle aze afike kumaphesenti angama-90 avamile.
Lapho abasubathi beziqeqesha kanzima noma ngamandla, kunokuthambekela kokuthi amazinga e-oxygen egazini ehle.Kodwa-ke uhlelo oluphumelelayo lokujima noma uhlobo lwemithi luhambisana nokuba nemisipha enothe nge-oksijini ithuthukisa ukusebenza kwemisipha nokusebenza kwayo yonke.Ukwengeza, ama-pulse oximeters angaphinda kabili njengethuluzi lokuhlola kumakhasimende abaqeqeshi bomuntu abanomsebenzi wamaphaphu osengozini noma wenhliziyo.Lokhu kubenza babe yithuluzi elihle lokuqapha lokuqondisa ukuqeqeshwa nokwandisa amandla.
Ama-finger pulse oximeter angamathuluzi okuqeqesha anenzuzo.Kulula ukuzisebenzisa futhi zihlangene ngakho akuthinti ukujima kokuqeqeshwa.Futhi ziyindlela enhle kakhulu yokuthi wena noma umuntu omqeqeshayo akhulule amandla akhe angasetshenzisiwe.
