I-oximeter yesiqeshana somunwe

Ngakho-ke, uyazi ukuthi ubani umsunguli we-pulse oximeter yesimanje?
Njengentuthuko eminingi yesayensi, i-pulse oximeter yesimanje yayingeyona ingqondo yengqondo ethile eyedwa.Kusukela embonweni wakudala, obuhlungu, ohamba kancane futhi ongasebenzi maphakathi nawo-1800, futhi othathe isikhathi esingaphezu kwekhulu, ososayensi abaningi nonjiniyela bezokwelapha baye baqhubeka nokwenza impumelelo kwezobuchwepheshe ekulinganiseni amazinga komoyampilo wegazi, belwela ukuhlinzeka ngokushesha, okuphathekayo nokungewona. - indlela ye-pulse oximetry engavamile.
1840 I-Hemoglobin, ethwala amangqamuzana omoya-mpilo egazini, yatholwa
Maphakathi nawo-1800s, ososayensi baqala ukuqonda indlela umzimba womuntu odonsa ngayo umoya-mpilo futhi uwusabalalise kuwo wonke umzimba.
Ngo-1840, uFriedrich Ludwig Hunefeld, ilungu le-German Biochemical Society, wathola isakhiwo sekristalu esithwala umoya-mpilo egazini, ngaleyo ndlela ehlwanyela imbewu ye-pulse oximetry yesimanje.
Ngo-1864 uFelix Hoppe-Seyler wanikeza lezi zakhiwo zekristalu eliwumlingo igama lazo, i-hemoglobin.Ukuhlola kukaHope-Thaylor nge-hemoglobin kwaholela isazi sezibalo nesazi se-physics sase-Ireland-saseBrithani uGeorge Gabriel Stokes ukuba ahlole “ukuncipha kombala nokukhipha i-oxidation yamaprotheni egazini.”
i-hemoglobin
Ngo-1864, uGeorge Gabriel Stokes noFelix Hoppe-Seyler bathola imiphumela ehlukile ye-spectral yegazi elicebile komoyampilo kanye ne-oxygen elimpofu ngaphansi kokukhanya.
Ukuhlola okwenziwa uGeorge Gabriel Stokes noFelix Hoppe-Seyler ngo-1864 kwathola ubufakazi obusobala be-hemoglobin ebopha umoya-mpilo.Baqaphele:
Igazi elinomoya-mpilo (i-hemoglobin ene-oksijini) libonakala libomvu njengetsheri elikhanyayo ngaphansi kokukhanya, kuyilapho igazi elingenawo umoya-mpilo (i-hemoglobin engenawo umoya) libonakala limnyama ngokunsomi ngokubomvu.Isampula legazi elifanayo lizoshintsha umbala lapho livezwe ekugxilweni komoyampilo okuhlukile.Igazi elinomoya-mpilo libonakala libomvu ngokugqamile, kuyilapho igazi elingenawo umoya-mpilo libonakala libomvu ngokujulile.Lokhu kushintsha kombala kungenxa yezinguquko ezicini zokumuncwa kwe-spectral zamangqamuzana e-hemoglobin lapho ehlangana noma ehlukana nomoya-mpilo.Lokhu kutholakala kunikeza ubufakazi obuqondile be-spectroscopic bomsebenzi wokuthwala umoya-mpilo egazini futhi kubeka isisekelo sesayensi sokuhlanganisa i-hemoglobin nomoya-mpilo.
UGeorge Gabriel Stokes
Kodwa ngesikhathi u-Stokes no-Hope-Taylor benza ucwaningo lwabo, okuwukuphela kwendlela yokukala amazinga e-oxygenation egazini lesiguli kwakusawukuthatha isampula yegazi futhi balihlaziye.Le ndlela ibuhlungu, iyahlasela, futhi iphuza kakhulu ukunikeza odokotela isikhathi esanele sokuthatha isinyathelo ngolwazi olunikezayo.Futhi noma iyiphi inqubo ehlaselayo noma yokungenelela inamandla okubangela ukutheleleka, ikakhulukazi ngesikhathi sokusikwa kwesikhumba noma izinti zezinaliti.Lokhu kutheleleka kungase kwenzeke endaweni noma kusakazeke kube ukutheleleka kwesistimu.ngaleyo ndlela kuholele kwezokwelapha
ingozi yokwelashwa.
