Ukubaluleka kokujongwa kweoksijini yegazi ekujongweni komntwana osanda kuzalwa akunakungahoywa. Ukujongwa kweoksijini yegazi kusetyenziswa ikakhulu ukuvavanya umthamo we-oxyhemoglobin edityaniswe neoksijini egazini leentsana ezisandula ukuzalwa njengepesenti yomthamo we-hemoglobin iyonke enokudityaniswa negazi, oko kukuthi, ukugcwala kweoksijini egazini. Oku kuneempembelelo ezibalulekileyo ekuqondeni ukuphefumla kunye nempilo yentliziyo yeentsana ezisanda kuzalwa.
Okokuqala, ukujonga ioksijini yegazi kunokunceda ngokukhawuleza ekuboneni ukuba iintsana ezisanda kuzalwa zineoksijini eyaneleyo. Ukuba i-oxygen saturation yegazi iphantsi kunoluhlu oluqhelekileyo (ngokuqhelekileyo i-91% -97%), inokubonisa ukuba umntwana osanda kuzalwa une-hypoxic, enokuba nefuthe elibi kumsebenzi wentliziyo, ingqondo kunye nezinye izitho ezibalulekileyo. Ngoko ke, ngokubeka iliso kwi-oksijini yegazi, oogqirha banokufumanisa kwaye bathathe amanyathelo onyango afanelekileyo ngexesha lokuphepha ukuwohloka ngakumbi kwimeko.
Nangona kunjalo, iimpawu ze-physiological zeentsana ezisanda kuzalwa zenza ukuba ukujonga i-oksijini yegazi kube nzima. Imithambo yegazi yabo mincinci kwaye isantya sokuhamba kwegazi sihamba kancinci, nto leyo enokubangela ukuba ukufunyanwa kwemiqondiso ye-oxygen yegazi kungazinzi kwaye kube lula kwiimpazamo. Ukongeza, iinkqubo zokuphefumla kunye nentliziyo yeentsana ezisanda kuzalwa azikavuthwa ngokupheleleyo, okuthetha ukuba xa bejongana neemeko ezithile ze-pathological, utshintsho kwi-blood saturation ye-oxygen lusenokungabonakali ngokwaneleyo, ukwenza ukubeka iliso kube nzima ngakumbi.
Itekhnoloji ye-oksijini yegazi ye-Narigmed ineziphumo ezigqwesileyo zomlinganiso phantsi kwe-perfusion ebuthathaka phakathi kwe-0.3% kunye ne-0.025%, ngokuchaneka okuphezulu kakhulu, kwaye ifaneleke ngakumbi ukulinganisa iintsana ezisanda kuzalwa.
