I-SpO₂ ingenye yezinkomba ezibalulekile zempilo yomzimba. I-SpO₂ yomuntu ophilile kahle kufanele igcinwe phakathi kuka-95%-100%. Uma ingaphansi kuka-90%, isingene ebangeni le-hypoxia, futhi uma ingaphansi kuka-80%% iyi-hypoxia enzima, engabangela umonakalo omkhulu emzimbeni futhi ibeke impilo engozini.

I-SpO₂ iyipharamitha ebalulekile yomzimba ekhombisa imisebenzi yokuphefumula kanye nokujikeleza kwegazi. Ngokwezibalo ezingaphelele, izizathu eziningi zokubonisana okuphuthumayo komnyango wokuphefumula eminyangweni efanele yesibhedlela zihlobene ne-SpO₂. Sonke siyazi ukuthi i-SpO₂ ephansi ayihlukaniseki nomnyango wokuphefumula, kodwa akuzona zonke ukwehla kwe-SpO₂ okubangelwa izifo zokuphefumula.

Yiziphi izizathu ze-SpO₂ ephansi?

1. Ukuthi ingcindezi engaphelele yomoya-mpilo ophefumulayo iphansi kakhulu yini. Uma okuqukethwe komoya-mpilo kugesi ophefumulayo kunganele, kungabangela ukwehla kwe-SpO₂. Ngokomlando wezokwelapha, isiguli kufanele sibuzwe ukuthi ngabe sike saya ezindaweni eziphakeme ngaphezu kwama-3000m, sindiza ezindaweni eziphakeme, sikhuphuka ngemva kokuntywila, kanye nezimayini ezingenawo umoya ofanele.

2. Ukuthi kukhona yini ukuvinjelwa komoya. Kuyadingeka ukucabangela ukuthi ngabe kukhona yini ukuvimba komoya okubangelwa yizifo ezifana ne-asthma kanye ne-COPD, ukuwa kwesisekelo solimi, kanye nokuvinjelwa kokukhishwa komzimba wangaphandle endleleni yokuphefumula.

3. Ingabe kukhona ukungasebenzi kahle komoya. Cabanga ngokuthi isiguli sinesifo sofuba esibi kakhulu, isifo sofuba esibi kakhulu, i-diffuse pulmonary fibrosis, i-pulmonary edema, i-pulmonary embolism nezinye izifo ezithinta umsebenzi womoya.

4. Iyini ikhwalithi kanye nobuningi be-Hb obuthutha umoya-mpilo egazini? Ukuvela kwezinto ezingavamile, njengobuthi be-CO, ubuthi be-nitrite, kanye nokwanda okukhulu kwe-hemoglobin engavamile, akugcini nje ngokuthinta kakhulu ukuthuthwa komoya-mpilo egazini, kodwa futhi kuthinta kakhulu ukukhishwa komoya-mpilo.

5. Ukuthi isiguli sinengcindezi ye-osmotic ye-colloid efanele kanye nomthamo wegazi ofanele yini. Umfutho we-osmotic we-colloidal ofanele kanye nomthamo wegazi owanele kungenye yezinto ezibalulekile zokugcina ukugcwala komoya-mpilo okuvamile.

6. Ungakanani umphumela wenhliziyo yesiguli? Ukuze kugcinwe ukuhanjiswa komoya-mpilo okuvamile kwesitho, kufanele kube nomphumela wenhliziyo owanele ukuze usisekele.

7. Ukujikeleza kwegazi okuncane kwezicubu nezitho zomzimba. Amandla okugcina umoya-mpilo ofanele nawo ahlobene nokusetshenziswa komzimba. Uma ukusetshenziswa komzimba emzimbeni kukhulu kakhulu, okuqukethwe umoya-mpilo egazini lemithambo kuzoncipha kakhulu. Ngemva kokuba igazi lemithambo lidlule ekujikelezeni kwegazi kwamaphaphu okuthunjiwe, kuzobangela ukuntuleka kwegazi okunamandla kakhulu.

8. Ukusetshenziswa komoya-mpilo ezicutshini ezizungezile. Amaseli ezicubu angasebenzisa umoya-mpilo kuphela esimweni samahhala, kanti umoya-mpilo ohlanganiswe ne-Hb ungasetshenziswa kuphela yizicubu lapho ukhishwa. Izinguquko ku-pH, 2,3-DPG, njll. zithinta ukuhlukaniswa komoya-mpilo kusuka ku-Hb.

9. Amandla okushaya kwenhliziyo. I-SpO₂ ilinganiswa ngokusekelwe ekushintsheni kokumuncwa okubangelwa ukushaya kwenhliziyo, ngakho-ke idivayisi yokufaka esikhundleni kumele ibekwe endaweni enegazi elishayayo. Noma yiziphi izinto ezenza buthaka ukugeleza kwegazi okushayayo, njengokushukunyiswa komkhuhlane, ukuvuselelwa kwemizwa ezwelayo, isifo sikashukela kanye neziguli ezine-arteriosclerosis, kuzonciphisa ukusebenza kokulinganisa kwethuluzi. I-SpO₂ ayikwazi ukutholakala ezigulini ezine-cardiopulmonary bypass kanye nokuma kwenhliziyo.

10. Eyokugcina, ngemva kokukhipha zonke izici ezingenhla, ungakhohlwa ukuthi i-SpO₂ ingase yehle 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 okukhulu, futhi ithuthukise ukuphepha kwesiguli. I-Temp-pluse oximeter ephathekayo yasekhaya ye-MedLinket ingalinganisa kahle nangokushesha izinga le-SpO₂ lily. Ngemuva kweminyaka yocwaningo oluqhubekayo, ukunemba kwayo kokulinganisa kulawulwa ku-2%, okungafinyelela ukulinganisa okunembile kwe-SpO₂, izinga lokushisa, kanye ne-pulse, okungahlangabezana nezidingo zobungcweti. Isidingo sokulinganisa.

Izinzuzo ze-MedLinket's finger clip Temp-pluse oximeter:

1. Inzwa yokushisa yangaphandle ingasetshenziswa ukukala nokurekhoda izinga lokushisa lomzimba njalo

2. Ingaxhunywa ku-sensor yangaphandle ye-SpO₂ ukuze ivumelane neziguli ezahlukene futhi ifinyelele ukulinganisa okuqhubekayo.

3. Qopha izinga lokushaya kwenhliziyo kanye ne-SpO₂

4. Ungasetha i-SpO₂, izinga lokushaya kwenhliziyo, imikhawulo ephezulu nephansi yokushisa komzimba, bese uphakamisa umkhawulo

5. Isibonisi singashintshwa, isikhombikubona se-waveform kanye ne-algorithm ye-patent yesibonisi sezinhlamvu ezinkulu kungakhethwa, futhi kungalinganiswa ngokunembile ngaphansi kokuphazamiseka komoya okubuthakathaka kanye ne-jitter. Sinomsebenzi we-serial port, olungele ukuhlanganiswa kwesistimu.

6. Isibonisi se-OLED, kungakhathaliseki ukuthi kusemini noma ebusuku, singabonakala ngokucacile

7. Amandla aphansi kanye nokuphila kwebhethri isikhathi eside, izindleko eziphansi zokusebenzisa
