Umgomo wokupakisha komkhathi oguquliwe (Imephu) ukufaka esikhundleni somoya ezikhwameni zokupakisha namabhokisi ane-anti-runosion gas (ukuxuba amagesi angu-2 kuya kwayi-4 ngokuya ngesimo sokudla okuhlanganisiwe , kuvimbela ukukhula kwamagciwane, kwehlisa ijubane izinga le-metabolic futhi kunwebe okusha noma impilo yeshelufu yokudla. Igesi esetshenzisiwe imvamisa i-CO2, N2, O2 noma inhlanganisela ehlukahlukene yayo, futhi igesi ngalinye linemiphumela ehlukile ekugcinweni kwenyama okusha. Ngaphansi kwemibandela efrijiwe (0 ℃), engeza i-CO2 ukugcwala kungathuthukisa kakhulu impilo eshalofini yenyama entsha, futhi ngasikhathi sinye vikela ukuhlukaniswa kombala wenyama ngenxa yokucindezela kwenyama okuphansi ngenxa yokucindezela kwenyama okuphansi ngenxa yokucindezela okuphansi komoya-nqygen. Ingulube ingagcinwa ngale ndlela okungenani izinsuku eziyi-100. Uma kungavimba ngempumelelo ukungcoliswa kwe-microbial ekuhlatshweni kokupakisha nokugcina, isikhathi sesitoreji singafinyelela izinyanga ezi-5.
Ngakho-ke, ukufakwa komkhathi okuguquliwe kwe-CE2 okulungisiwe kulungele izinto zokuhamba ezithengiswayo okuphelele, izindlela zokuhamba ezinde nezindlela zokuthengisa ezidinga impilo ende eshalofini. Ukuze wenze inyama ibomvu ebomvu futhi ithandwane nabathengi, ngaphambi kokudla, yathathelwa indawo nge-oxygen equkethe i-oxygen, ngakho-ke umoya-mpilo uxhumana nenyama e-oxymyoglobin ebomvu, ukuze uhehe abathengi abazothenga.
