摘要：
A system for delivering oxygen to a substantially stationary patient without coupling a device to the body of the patient is disclosed. The system includes a source of oxygen coupled to a delivery system wherein the delivery system has a pump configured to pressurize oxygen and an elongate hollow member operatively coupled to the pump. The elongate hollow member has a proximal end and a distal end and is constructed to receive oxygen in its proximal end and deliver oxygen to the patient out the distal end. The length and diameter of the elongate member, the flow of oxygen through the elongate member, and the distance from the distal end of the elongate member to the face of the patient are optimized to collimate a stream of oxygen such that when the stream of oxygen reaches the patients face it envelops the face of the patient.
