Yintoni unobangela wokugcwala okusezantsi kweoksijini egazini?

A.

Xa kufunyenwe ukuba i-oxygen saturation yesigulane exhunywe ngokuthe ngqo kwikhebula le-ECG iyancitshiswa, le miba ilandelayo kufuneka iqwalaselwe nganye nganye ukufumana ingxaki.
1. Ngaba inxenye yoxinzelelo lweoksijini etsalweyo iphantsi kakhulu?Xa umxholo we-oksijini kwi-gas inhaled ayanelanga, i-oxygen saturation egazini inokuncipha.Izigulana kufuneka zibuzwe ukuba ngaba zikhe zaya kumathafa angaphezu kwama-3000m ngaphezu komphakamo wolwandle, zibhabha kwindawo ephakamileyo, zinyuke emva kokuntywila, kunye neendawo ezingenalo umoya wokungena umoya kakuhle ngokusekwe kwimbali yonyango.

1.Ingaba kukho isithintelo sokuhamba komoya?Kuyimfuneko ukuqwalasela ukuba kukho i-hypoventilation ephazamisayo ebangelwa zizifo ezifana ne-asthma kunye ne-COPD, ukuhla kolwimi, kunye nokukhutshwa kokuphefumula.

2.Ngaba iUluvo lwe-SpO2Ngaba unokungasebenzi kakuhle kwe-ventilatory ngenxa yokugcwala okuphantsi kweoksijini?Qwalasela ukuba ngaba isigulana sinenyumoniya eqatha, isifo sephepha esinamandla, i-pulmonary fibrosis, i-pulmonary edema, i-pulmonary embolism kunye nezinye izifo ezichaphazela umoya.

3.Yintoni umgangatho kunye nobungakanani be-Hb ehambisa ioksijini egazini?Ukwenzeka kwezinto ezingaqhelekanga ezifana ne-carbon monoxide poisoning, i-nitrite poisoning kunye nokunyuka kwe-hemoglobin engaqhelekanga akuchaphazeli kakhulu ukuthuthwa kwe-oksijini egazini, kodwa kuchaphazela kakhulu ukukhululwa kwe-oksijini.

1.Ingaba isigulane sine-colloid efanelekileyo ye-osmotic uxinzelelo kunye nomthamo wegazi.Uxinzelelo olufanelekileyo lwe-colloidal osmotic kunye nomthamo wegazi owaneleyo zizinto eziphambili zokugcina ukugcwala okuqhelekileyo kwe-oksijini eboniswa yikliphu yomnwe yabantu abadala.Uluvo lwe-SpO2.

2.Yintoni isiphumo sentliziyo yesigulane?Ubungakanani beoksijini enikezelweyo ukugcina izitho eziqhelekileyo kufuneka zixhaswe ngokuphuma kwentliziyo eyaneleyo.

3.I-Microcirculation yezicubu kunye namalungu.Nokuba kugcinwe ioksijini efanelekileyo kukwanxulumene nemetabolism yomzimba.Xa i-metabolism yomzimba iphezulu kakhulu, umxholo weoksijini kwigazi le-venous uya kuncitshiswa kakhulu, kwaye igazi le-venous liya kubangela i-hypoxia enzima ngakumbi emva kokuvalela ukujikeleza kwemiphunga.

4.Sebenzisa ioksijini kwizicubu ezijikelezileyo.Iiseli zezicubu zinokusebenzisa ioksijini yasimahla, kwaye ioksijini edityaniswe ne-Hb inokukhutshwa kuphela kwizicubu ukuze zisetyenziswe.Utshintsho kwi-pH, i-2,3-DPG, njl njl kuya kuchaphazela ukuchithwa kwe-oxygen kwi-Hb.

5. Emva kokuphelisa zonke ezi zinto zingentla, nceda ungalibali ukuba oku kunokubangelwa ukuhla kwe-oksijini ye-saturation ebangelwa ukungasebenzi kakuhle kwe-sensor ye-clamp finger.
