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 yomzimba 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 okubangelwa 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 ilinganiswa ngokusekelwe ekushintsheni kokumunca okukhiqizwa ukushaya kwe-arterial pulsation, 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 lomnduze we-SpO₂. Ngemva kweminyaka yocwaningo oluqhubekayo, ukunemba kokulinganisa kwayo kulawulwa ku-2%, okungafinyelela ukulinganiswa okunembile kwe-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 ezahlukene futhi ifinyelele ukulinganisa okuqhubekayo.

3. Rekhoda izinga lokushaya kwenhliziyo kanye ne-SpO₂

4. Ungasetha i-SpO₂, izinga lokushaya kwenhliziyo, imikhawulo ephezulu nephansi yezinga lokushisa lomzimba, futhi utshele ngaphezu komkhawulo

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
