Regional gas exchange evaluation during ex vivo lung perfusion in a swine model of localized lung dysfunction

Animal Models and Experimental Medicine, EarlyView.
Abstract Background Ex vivo lung perfusion (EVLP) allows the evaluation of lungs that do not meet standard transplantation criteria. Current procedures do not permit the identification of regional functional deficits. We investigated the feasibility of assessing lobar gas exchange during EVLP in a swine model.
