Ngwa iku ume sistemu ECMO maka akụrụngwa “akpa ume arụrụ arụ” ECMO

ECMO, ma ọ bụ extracorporeal membrane pulmonary oxygenation, bụ usoro nkwado ndụ nke na-eji ngwá ọrụ arụrụ pụrụ iche na-amịpụta ọbara n'ime obi, gbanwee ya maka gas, gbanwee okpomọkụ ya ma gụghachi ya n'ime akwara nke ahụ. ECMO bụ ụdị nkwado kachasị mkpa ugbu a maka ọdịda obi mgbawa siri ike ma akọwara ya dị ka "ebe ikpeazụ" maka ndị ọrịa nwere nnukwu oyi baa neocoronary.
