<p>A device for the application of continuous positive airway pressure (CPAP) delivering 100% oxygen during thoracic surgery utilizing one-lung anesthesia. The device comprises a hollow, cylindrical member serving as a conduit for oxygen. One end of the device is connected to a source of oxygen delivered at a constant flow rate. The opposite end attaches to one lumen of a double-lumen endotracheal tube. A removable cap is attached to the device. If the cap is removed, a breathing bag can be attached for allowing the periodic expansion of the lung connected to the apparatus. A venting device is provided to allow the egress of oxygen under pressure. By changing a venting orifice, varying degrees of pressure of oxygen will be delivered to the one lumen of the double-lumen tube.</p> |
