Abstract

A passive continuous positive airway intratracheal pulmonary ventilation system which includes an inspiration limb (70) and an expiration limb (71) which are pressure balanced by inflatable bags (73a, 73b). An intratracheal pulmonary ventilation system is provided which includes a catheter (82) having a tip (90) which is positioned through a low resistance endotracheal tube (81) at or near a patient's carina (92). A constant source of an oxygen-containing gas flows through the catheter (82). The catheter has a tip (90) which deflects and reserves the flow direction of the oxygen-containing gas.
