I-SpO2 ingenye yezinkomba ezibalulekile zempilo yomzimba.I-SpO2 yomuntu onempilo evamile kufanele igcinwe phakathi kuka-95% -100%.Uma ingaphansi kuka-90%, ingene ebangeni le-hypoxia, futhi uma isingaphansi kuka-80% % I-hypoxia enzima, engabangela umonakalo omkhulu emzimbeni futhi ibeke ukuphila engozini.
I-SpO2 iyipharamitha ebalulekile yokuphila ebonisa imisebenzi yokuphefumula nokujikeleza kwegazi.Ngokwezibalo ezingaphelele, iningi lezizathu zokubonisana okuphuthumayo komnyango wokuphefumula eminyangweni efanele yesibhedlela zihlobene ne-SpO2.Sonke siyazi ukuthi i-SpO2 ephansi ayinakuhlukaniswa nomnyango wokuphefumula, kodwa akuwona wonke ukuncipha kwe-SpO2 kubangelwa izifo zokuphefumula.
Yiziphi izizathu ze-SpO2 ephansi?
1. Ukuthi umfutho oyingxenye womoya-mpilo ohogelwe uphansi kakhulu yini.Uma okuqukethwe komoyampilo kwegesi ehogeliwe kunganele, kungabangela ukuncipha kwe-SpO2.Ngokomlando wezokwelapha, isiguli kufanele sibuzwe ukuthi ngabe sake safika yini endaweni ephakeme ngaphezu kuka-3000m, sindiza endaweni ephakeme, sikhuphuka ngemva kokutshuza, kanye nezimayini ezingenawo umoya ohlanzekile.
2. Ukuthi kukhona yini ukuvinjelwa kokugeleza komoya.Kudingekile ukucabangela ukuthi kukhona yini i-hypoventilation evimbelayo ebangelwa izifo ezifana ne-asthma ne-COPD, ukuwa kwesisekelo solimi, nokuvinjelwa kokukhishwa komzimba wangaphandle emgudwini wokuphefumula.
3. Ukuthi kukhona ukungasebenzi kahle kwe-ventilation.Cabanga ukuthi isiguli sine-pneumonia enzima, isifo sofuba esibi kakhulu, i-pulmonary fibrosis esabalalisa, i-pulmonary edema, i-pulmonary embolism nezinye izifo ezithinta umsebenzi wokuphefumula.
4. Ingakanani ikhwalithi nenani le-Hb ehambisa umoya-mpilo egazini?Ukubonakala kwezinto ezingavamile, njengobuthi be-CO, ubuthi be-nitrite, nokwanda okukhulu kwe-hemoglobin engavamile, akuthinti nje kuphela ukuthuthwa komoya-mpilo egazini, kodwa futhi kuthinta kakhulu ukukhululwa komoya-mpilo.
5. Ukuthi isiguli sine-colloid osmotic pressure efanele kanye nevolumu yegazi.Umfutho ofanelekile we-colloidal osmotic kanye nevolumu yegazi eyanele kungenye yezinto ezibalulekile zokugcina ukugcwala komoyampilo okuvamile.
6. Kuyini ukuphuma kwenhliziyo yesiguli?Ukugcina ukulethwa komoyampilo okuvamile kwesitho, kufanele kube nokuphuma kwenhliziyo okwanele ukuze kusekelwe.
7. I-Microcirculation yezicubu nezitho.Amandla okugcina umoya-mpilo ofanele nawo ahlobene nokusetshenziswa komzimba komzimba.Uma i-metabolism yomzimba inkulu kakhulu, okuqukethwe komoyampilo egazini le-venous kuzoncipha kakhulu.Ngemuva kokuthi igazi le-venous lidlule ekujikelezeni kwe-shunted pulmonary, kuzodala i-hypoxia enzima kakhulu.
8. Ukusetshenziswa komoyampilo ezicutshini ezizungezile.Amaseli ezicubu angasebenzisa umoya-mpilo kuphela esimweni esikhululekile, futhi umoya-mpilo ohlangene ne-Hb ungasetshenziswa kuphela izicubu lapho ukhululwa.Izinguquko ku-pH, 2,3-DPG, njll. zithinta ukuhlukaniswa komoyampilo ku-Hb.
9. Amandla okushaya kwenhliziyo.I-SpO2 ikalwa ngokusekelwe ekushintsheni kokumunca okukhiqizwa ukushayeka kwe-arterial, ngakho umshini wokubuyisela kufanele ubekwe endaweni enegazi elishayayo.Noma yiziphi izici ezenza buthaka ukugeleza kwegazi elithambile, njengokushukumisa amakhaza, injabulo yezinzwa ezinozwela, isifo sikashukela kanye neziguli ze-arteriosclerosis, kuzonciphisa ukusebenza kokulinganisa kwethuluzi.I-SpO2 ayikwazi ukutholwa ezigulini ezine-cardiopulmonary bypass kanye nokuboshwa kwenhliziyo.
10. Esokugcina, ngemva kokungabandakanyi zonke izici ezingenhla, ungakhohlwa ukuthi i-SpO2 ingase yehliswe ngenxa yokungasebenzi kahle kwethuluzi.
I-oximeter iyithuluzi elivamile lokuqapha i-SpO2.Ingabonisa ngokushesha i-SpO2 yomzimba wesiguli, iqonde umsebenzi we-SpO2 womzimba, ibone i-hypoxemia ngokushesha ngangokunokwenzeka, futhi ithuthukise ukuphepha kwesiguli.I-Medlinket yasekhaya ephathekayo ye-Temp-pluse oximeter ingakwazi ukukala kahle futhi ngokushesha izinga le-SpO2 lily.Ngemva kweminyaka yocwaningo oluqhubekayo, ukunemba kwesilinganiso sayo kulawulwa ku-2%, okungafinyelela isilinganiso esinembile se-SpO2, izinga lokushisa, kanye ne-pulse, engahlangabezana nezidingo zobungcweti.Isidingo sokulinganisa.
Izinzuzo zesiqeshana somunwe sika-Medlinket I-Temp-pluse oximeter:
1. Inzwa yangaphandle yezinga lokushisa ingasetshenziselwa ukulinganisa ngokuqhubekayo nokurekhoda izinga lokushisa lomzimba
2. Ingaxhunywa kunzwa yangaphandle ye-SpO2 ukuze ivumelane neziguli ezihlukene futhi ifinyelele ukulinganisa okuqhubekayo.
3. Qopha izinga lokushaya kwenhliziyo kanye ne-SpO2
4. Ungasetha i-SpO2, izinga lokushaya kwenhliziyo, imikhawulo ephezulu nephansi yezinga lokushisa lomzimba, futhi usheshise umkhawulo
5. Isibonisi singashintshwa, isixhumi esibonakalayo se-waveform kanye ne-algorithm ye-patent yezinhlamvu ezinkulu kungakhethwa, futhi kungalinganiswa ngokunembile ngaphansi kwe-perfusion ebuthakathaka kanye ne-jitter.Inomsebenzi we-serial port, olungele ukuhlanganiswa kwesistimu.
6. Isibonisi se-OLED, kungakhathaliseki ukuthi kusemini noma ebusuku, singabonisa ngokucacile
7. Amandla aphansi nempilo ende yebhethri, izindleko eziphansi zokusetshenziswa
