Ukuzaliswa kwe-oxygen yegazi sesinye sezibonakaliso ezibalulekileyo zempilo yomzimba.Ukuzaliswa kwe-oksijini yegazi yabantu abasempilweni eqhelekileyo kufuneka kugcinwe phakathi kwe-95% kunye ne-100%.Ukuba ingaphantsi kwe-90%, ingene kuluhlu lwe-hypoxia.I-% yi-hypoxia enzima, eya kubangela umonakalo omkhulu emzimbeni kwaye ibeke ubomi engozini.
I-blood oxygen saturation yiparameter ebalulekileyo ye-physiological ebonisa umsebenzi wokuphefumula kunye nokujikeleza.Ngokwezibalo ezingaphelelanga, ezininzi zezizathu zokubonisana ngokukhawuleza kunye namasebe okuphefumula kumasebe afanelekileyo kwizibhedlele zihambelana ne-oksijeni yegazi.Sonke siyazi ukuba i-oxygen saturation ephantsi ayinakwahlulwa kwizifo zokuphefumla, kodwa ayizizo zonke ezinciphayo kwi-oxygen saturation yegazi zibangelwa zizifo zokuphefumula.
Zeziphi izizathu zokugcwala kweoksijini ephantsi egazini?
1. Nokuba inxenye yoxinzelelo lweoksijini erholeyo iphantsi kakhulu.Xa umthamo we-oksijini ophefumlelweyo ungonelanga, ukugcwala kwe-oxygen kunokuhla.Idityaniswe nembali yonyango, isigulana kufuneka sibuzwe ukuba sakha saya kwithafa elingaphezulu kwe-3000m, ukubhabha okuphakamileyo, ukunyuka emva kokuntywila, kunye nemigodi engenamoya kakuhle.
2. Nokuba kukho isithintelo sokuhamba komoya.Kuyimfuneko ukuqwalasela ukuba kukho i-hypoventilation ephazamisayo ebangelwa zizifo ezifana ne-asthma, i-COPD, i-root root root, kunye nokuphazamiseka komzimba wangaphandle wemfihlo yokuphefumula.
3. Ingaba kukho ukungasebenzi kakuhle kokungena komoya.Kufuneka ucinge malunga nokuba isigulane sinenyumoniya enzima, isifo sofuba esibi, i-pulmonary interstitial fibrosis, i-pulmonary edema, i-pulmonary embolism kunye nezinye izifo ezichaphazela umsebenzi wokuphefumula.
4. Yintoni umgangatho kunye nobungakanani be-Hb 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-colloid osmotic kunye nomthamo wegazi owaneleyo yenye yezinto eziphambili zokugcina i-oxygen saturation eqhelekileyo.
6. Yintoni umphumo wentliziyo yesigulane?Ukugcina ukuhanjiswa kwe-oksijini eqhelekileyo kwizitho kufuneka kuxhaswe ngokuphuma kwentliziyo eyaneleyo.
7. Izicubu kunye ne-microcirculation yamalungu.Ukukwazi ukugcina ioksijini efanelekileyo kukwanxulumene nemetabolism yomzimba.Xa i-metabolism yomzimba inkulu kakhulu, umxholo we-oksijini we-venous wegazi uya kuncitshiswa kakhulu, kwaye igazi le-venous liya kukhokelela kwi-hypoxia enzima kakhulu emva kokudlula kwi-shunted pulmonary circulation.
8. Ukusetyenziswa kweoksijini kwizicubu ezijikelezileyo.Iiseli zezicubu zingasebenzisa kuphela i-oksijini yamahhala, kwaye i-oksijini edibeneyo ne-Hb ingasetyenziselwa kuphela izicubu xa ikhutshwa.Utshintsho kwi-pH, i-2,3-DPG, njl.
9. Amandla okubetha kwentliziyo.I-oxygen saturation ilinganiswa ngokusekelwe kwinguqu kwi-absorption eveliswa yi-arterial pulsation, ngoko ke i-transducer kufuneka ibekwe 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 ayinakubonwa nakwizigulane ezine-cardiopulmonary bypass kunye nokubanjwa kwentliziyo.
