Efficacy of coaxial ventilation with a novel endotracheal catheter equipped with a functional cuff: A swine model study.

BACKGROUNDWe have developed an endotracheal catheter with a functional cuff (ECFC) that inflates during inspiration and deflates during expiration. This catheter, together with a regular ICU ventilator, can provide coaxial ventilation.OBJECTIVEThe aim of this study was to determine the efficacy of v
