Ukubaluleka kokuqapha umoya-mpilo wegazi ekuqaphelweni kwezingane ezisanda kuzalwa angeke kushaywe indiva. Ukuqapha komoyampilo wegazi kusetshenziswa kakhulu ukuhlola umthamo we-oxyhemoglobin ehlanganiswe nomoya-mpilo egazini lezingane ezisanda kuzalwa njengephesenti lengqikithi yomthamo we-hemoglobin engahlanganiswa negazi, okungukuthi, ukugcwala komoyampilo egazini. Lokhu kunemithelela ebalulekile ekuqondeni impilo yokuphefumula neyenhliziyo yezingane ezisanda kuzalwa.
Okokuqala, ukuqapha komoyampilo wegazi kungasiza ekutholeni ngokushesha ukuthi izingane ezisanda kuzalwa azinawo yini umoya-mpilo owanele. Uma ukugcwala komoyampilo egazini kuphansi kunobubanzi obujwayelekile (ngokuvamile u-91% -97%), kungase kubonise ukuthi umntwana osanda kuzalwa une-hypoxic, okungase kube nomthelela omubi emsebenzini wenhliziyo, ubuchopho, nezinye izitho ezibalulekile. Ngakho-ke, ngokuqapha kwe-oksijeni yegazi, odokotela bangakwazi ukubona futhi bathathe izinyathelo zokwelashwa ezifanele ngesikhathi ukuze bagweme ukuwohloka okuqhubekayo kwesimo.
Kodwa-ke, izici zomzimba zezingane ezisanda kuzalwa zenza ukuqapha komoyampilo wegazi kube nzima. Imithambo yegazi yabo mincane futhi izinga lokugeleza kwegazi lihamba kancane, okungase kubangele ukutholwa kwezimpawu zomoya wegazi ukuthi kungazinzi futhi kuthambekele emaphutheni. Ngaphezu kwalokho, izinhlelo zokuphefumula nezenhliziyo zezingane ezisanda kuzalwa azikavuthwa ngokugcwele, okusho ukuthi lapho zibhekene nezimo ezithile ze-pathological, izinguquko ekugcwalisweni kwe-oksijini egazini zingase zingabonakali ngokwanele, okwenza ukuqapha kube nzima nakakhulu.
Ubuchwepheshe be-oksijini yegazi le-Narigmed bunemiphumela emihle kakhulu yokulinganisa ngaphansi kwe-perfusion ebuthaka phakathi kuka-0.3% no-0.025%, ngokunemba okuphezulu kakhulu, futhi kulungele ngokukhethekile ukukalwa kwezingane ezisanda kuzalwa.
