A device (10) for the application of continuous positive airway pressure (CPAP) delivering 100 % oxygen during thoracic surgery utilizing one-lung anesthesia. The device (10) consists of a hollow, cylindrical member (11) serving as a conduit for oxy- gen. One end (14) of the device (10) is connected to a source of oxygen (23) delivered at a constant flow rate. The opposite end (13) attaches to one lumen (2) of a double-lumen endotracheal tube (1). A removable cap (15) is attached to the device (10, 13). If the cap (15) is removed, a breathing bag (24) can be attached for allowing the periodic expansion of the lung (5, 8) connected to the apparatus. A venting device (V) is provided to allow the egress of oxygen under pressure. By changing a venting orifice (16, 17), varying degrees of pressure of oxygen will be delivered to the one-lumen (2) of the double-lumen tube (1).
