Umsebenzi wokufunxa i-oksijeni: Ngokufunxa i-oksijini, inokuphucula ngokufanelekileyo imeko ye-hypoxia yomzimba kwaye ifezekise injongo ye-oxygen yokuncedisa ukhathalelo lwempilo. I-Lt ilungele abantu abadala, abasetyhini kunye nabagulayo, kunye nabafundi abane-hypoxia eyahlukileyo. Kwakhona kunokuba kukuphelisa ukudinwa kunye nokubuyisela ngokukhawuleza ukusebenza komzimba emva kokuzivocavoca umzimba okanye kwengqondo.
Le mveliso isisefu esikumgangatho ophezulu wemolekyuli efunxa ioksijini (i-PSA ikhupha ioksijini ngqo emoyeni). Umatshini weoksijini mncinane ngobukhulu, ulula ngobunzima, uphantsi ngamandla, uphantsi ngengxolo, kwaye kulula ukusebenza.
