I-SpO₂ yenye yezibonakaliso ezibalulekileyo zempilo yomzimba. I-SpO₂ yomntu onempilo eqhelekileyo kufuneka igcinwe phakathi kwe-95% -100%. Ukuba ingaphantsi kwama-90%, ingene kuluhlu lwe-hypoxia, kwaye emva kokuba iphantsi kwe-80% % Ngaba i-hypoxia enzima, enokubangela umonakalo omkhulu emzimbeni kwaye ibeka ubomi engozini.

I-SpO₂ iyipharamitha ebalulekileyo ye-physiological ebonisa imisebenzi yokuphefumula kunye nokujikeleza. Ngokwezibalo ezingaphelelanga, ezininzi zezizathu zokubonisana ngokukhawuleza kwesebe lokuphefumula kumasebe afanelekileyo esibhedlele zihambelana ne-SpO₂. Sonke siyazi ukuba i-SpO₂ ephantsi ayinakuhlukaniswa kwisebe lokuphefumula, kodwa akusiyo yonke into eyancipha kwi-SpO₂ ebangelwa zizifo zokuphefumula.

Ziziphi izizathu ze-SpO₂ ephantsi?

1. Nokuba inxenye yoxinzelelo lweoksijini erholeyo iphantsi kakhulu. Xa umxholo we-oksijini wegesi ekhutshweyo ayinelanga, inokubangela ukuhla kwe-SpO₂. Ngokwembali yonyango, isigulana kufuneka sibuzwe ukuba ngaba ukhe waya kwindawo ephakamileyo engaphezulu kwe-3000m, ebhabha kwindawo ephakamileyo, enyuka emva kokuntywila, kunye nemigodi engenamoya kakuhle.

2. Nokuba kukho isithintelo sokuhamba komoya. Kuyimfuneko ukuqwalasela ukuba kukho i-hypoventilation ephazamisayo ebangelwa zizifo ezifana ne-asthma kunye ne-COPD, ukuwa kwesiseko solwimi, kunye nokuphazamiseka kwemfihlo yomzimba wangaphandle kwindlela yokuphefumula.

3. Ingaba kukho ukungasebenzi kakuhle kokungena komoya. Cinga malunga nokuba isigulane sinenyumoniya enzima, isifo sofuba esibi kakhulu, i-pulmonary fibrosis, i-pulmonary edema, i-pulmonary embolism kunye nezinye izifo ezichaphazela umsebenzi wokuphefumula.

4. Ungakanani umgangatho kunye nobungakanani beHb ehambisa ioksijini egazini? Ukubonakala kwezinto ezingaqhelekanga, ezifana ne-CO poisoning, i-nitrite poisoning, kunye nokunyuka okukhulu kwe-hemoglobin engaqhelekanga, akuchaphazeli kakhulu ukuthuthwa kwe-oksijini egazini, kodwa kuchaphazela kakhulu ukukhululwa kwe-oksijini.

5. Ingaba isigulane sinoxinzelelo olufanelekileyo lwe-colloid osmotic kunye nomthamo wegazi. Uxinzelelo olufanelekileyo lwe-colloidal osmotic kunye nomthamo wegazi owaneleyo yenye yezinto eziphambili zokugcina i-oxygen saturation eqhelekileyo.

6. Yintoni umphumo wentliziyo yesigulane? Ukugcina ukuhanjiswa kwe-oksijini eqhelekileyo yelungu, kufuneka kubekho imveliso eyaneleyo yenhliziyo ukuyixhasa.

7. I-Microcirculation yezicubu kunye nezitho. Ukukwazi ukugcina ioksijini efanelekileyo kukwanxulumene nemetabolism yomzimba. Xa i-metabolism yomzimba inkulu kakhulu, umxholo weoksijini wegazi le-venous uya kuncitshiswa kakhulu. Emva kokuba igazi le-venous lidlula kwi-shunted pulmonary circulation, liya kubangela i-hypoxia enzima ngakumbi.

8. Ukusetyenziswa kweoksijini kwizihlunu ezingqongileyo. Iiseli zezicubu zingasebenzisa kuphela i-oksijini kwindawo ekhululekile, kwaye i-oksijini edibeneyo ne-Hb ingasetyenziselwa kuphela izicubu xa ikhutshwa. Utshintsho kwi-pH, i-2,3-DPG, njl.

9. Amandla okubetha kwentliziyo. I-SpO₂ ilinganiswa ngokusekelwe kwinguqu ye-absorption eveliswa yi-arterial pulsation, ngoko ke isixhobo sokutshintshwa kufuneka sibekwe kwindawo enegazi elibethayo. Naziphi na izinto ezenza buthathaka ukuhamba kwegazi kwe-pulsatile, ezifana nokuvuselela okubandayo, i-excitement nerve excitement, isifo sikashukela kunye nezigulane ze-arteriosclerosis, ziya kunciphisa ukusebenza kokulinganisa kwesixhobo. I-SpO₂ ayinakufunyanwa kwizigulane ezine-cardiopulmonary bypass kunye nokubanjwa kwentliziyo.

10. Eyokugqibela, emva kokungabandakanyi zonke ezi zinto zingasentla, ungalibali ukuba i-SpO₂ inokuncipha ngenxa yokungasebenzi kakuhle kwesixhobo.

I-oximeter sisixhobo esiqhelekileyo sokubeka iliso kwi-SpO₂. Inokubonakalisa ngokukhawuleza i-SpO₂ yomzimba wesigulane, iqonde umsebenzi we-SpO₂ womzimba, ibone i-hypoxemia ngokukhawuleza, kwaye iphucule ukhuseleko lwesigulane. I-MedLinket yasekhaya ephathekayo ye-Temp-pluse oximeter inokulinganisa ngokufanelekileyo kwaye ngokukhawuleza ukulinganisa inqanaba le-SpO₂ lily. Emva kweminyaka yophando oluqhubekayo, ukuchaneka kokulinganisa kwayo kulawulwa kwi-2%, enokufikelela umlinganiselo ochanekileyo we-SpO₂, ukushisa, kunye ne-pulse, enokuthi ihlangabezane neemfuno zobuchwephesha. Isidingo somlinganiselo.

Izinto eziluncedo kwikliphu yomnwe yeMedLinket Temp-pluse oximeter:

1. Inzwa yokushisa yangaphandle ingasetyenziselwa ukulinganisa ngokuqhubekayo kunye nokurekhoda ukushisa komzimba

2. Inokudibaniswa kwi-sensor ye-SpO₂ yangaphandle ukulungelelanisa izigulane ezahlukeneyo kunye nokufezekisa umlinganiselo oqhubekayo.

3. Rekhoda izinga le-pulse kunye ne-SpO₂

4. Unokuseta i-SpO₂, izinga lokubetha, imida ephezulu kunye nesezantsi yobushushu bomzimba, kwaye ukhawuleze ngaphezulu komda.

5. Umboniso unokutshintshwa, i-interface ye-waveform kunye ne-algorithm ye-patent ye-algorithm ye-character enkulu inokukhethwa, kwaye inokulinganiswa ngokuchanekileyo phantsi kwe-perfusion ebuthakathaka kunye ne-jitter. Inomsebenzi we-serial port, olungele ukuhlanganiswa kwenkqubo.

6. Isibonisi se-OLED, kungakhathaliseki imini okanye ubusuku, sinokubonisa ngokucacileyo

7. Amandla aphantsi kunye nobomi bebhetri obude, ixabiso eliphantsi lokusetyenziswa
