Inqanaba le-oxygen egazini (i-arterial blood oxygen content) libonisa inqanaba le-oxygen ekhoyo egazini elihamba ngemithambo yomzimba.Uvavanyo lwe-ABG lusebenzisa igazi elitsalwa kwimithambo, elinokulinganiswa ngaphambi kokuba lingene kwizicubu zomntu.Igazi liya kufakwa kumatshini we-ABG (i-analyzer yegesi yegazi), enika amanqanaba e-oksijini yegazi ngendlela yoxinzelelo lwe-oxygen inxalenye (uxinzelelo lwe-oxygen partial).
I-Hyperoxaemia idla ngokufunyanwa ngokusebenzisa uvavanyo lwe-ABG, oluchazwa njengamanqanaba e-oksijini yegazi ngaphezu kwe-120 mmHg.Uxinzelelo lwe-oxygen oluqhelekileyo lwe-oxygen (PaO2) olulinganiswa kusetyenziswa i-arterial blood gas (ABG) uvavanyo malunga ne-75 ukuya kwi-100 mmHg (75-100 mmHg).Xa inqanaba lingaphantsi kwe-75 mmHg, le meko idla ngokubizwa ngokuba yi-hypoxemia.Amanqanaba angaphantsi kwe-60 mmHg abhekwa njengephantsi kakhulu kwaye abonisa imfuno ye-oksijeni eyongezelelweyo.Ioksijini eyongezelelweyo inikezelwa nge-cylinder ye-oxygen, edityaniswe nempumlo ngetyhubhu ene-mask okanye ngaphandle kwayo.
Kufuneka ube yintoni umxholo weoksijini?
Amanqanaba eoksijini yegazi nawo anokulinganiswa kusetyenziswa isixhobo esibizwa ngokuba yi-pulse oximeter.Inqanaba le-oksijeni eliqhelekileyo kwi-pulse oximeter lidla ngokuba yi-95% ukuya kwi-100%.Ngaphantsi kwe-90% yamanqanaba e-oksijini yegazi aphantsi (hypoxemia).I-Hyperoxaemia idla ngokubonwa ngovavanyo lwe-ABG, oluchazwa njengamanqanaba e-oksijini yegazi ngaphezu kwe-120 mmHg.Oku ngokuqhelekileyo esibhedlele, xa isigulane sibonakaliswe kuxinzelelo oluphezulu lwe-oksijeni eyongezelelweyo ixesha elide (i-3 kwiiyure ze-10 okanye ngaphezulu).
Yintoni ebangela ukuba izinga leoksijini egazini lehle?
Amanqanaba eoksijini yegazi anokwehla ngenxa yayo nayiphi na ingxaki elandelayo:
Isiqulatho seoksijini esemoyeni siphantsi: Kwiindawo eziphakamileyo ezifana neentaba, ioksijini esemoyeni iphantsi kakhulu.
Amandla omzimba womntu okufunxa ioksijini ayancipha: Oku kunokubangelwa zezi zigulo zemiphunga zilandelayo: Isifuba somoya, i-emphysema (ukonakala kweengxowa zomoya emiphungeni), ibronchitis, inyumoniya, ipneumothorax (ukuvuza komoya phakathi kwemiphunga kunye nodonga lwesifuba), ngokuqatha. i-respiratory distress syndrome (ARDS), i-pulmonary edema (ngenxa yokudumba kwemiphunga eqokelelweyo), i-Pulmonary fibrosis (i-scarring of the lungs), isifo se-interstitial lung (inani elikhulu lezifo zemiphunga ezidla ngokubangela ukukrala kwemiphunga), usulelo lwentsholongwane, olunjalo. njenge-COVID-19
Ezinye iimeko ziquka: i-anemia, i-apnea yokulala (ukulala ngelixa uphefumla okwethutyana), ukutshaya.
Ukukwazi kwentliziyo ukubonelela ngeoksijini emiphungeni kuyancipha: eyona nto ixhaphakileyo sisifo sentliziyo esizalwa naso (iziphene zentliziyo ekuzalweni).
