Abstract: An apparatus and method for providing heat exchange in the lungs of the mammal during partial liquid ventilation are provided. The apparatus and method can control delivery and removal of partial liquid ventilation to the lungs of a mammal by responding to pressure change in the lungs to minimize danger of causing barotrauma to the patient.

Abstract: A suspender loop buckle which has a latch for adjustment of the size of the loop and a clamp for secure attachment of the suspender strap to the buckle. The latch and clamp mechanisms both consist of a pivoting plate attached to the frame of the buckle and operate under similar principles. In the open position a plate is perpendicular to the frame and the strap can move freely between the plate and the frame. In the closed position a plate is parallel to frame and the strap is secured by pressure against a serrated flange. Whereas the latch can be easily opened by pressure on the edge of the latch in the direction of the frame, the clamp cannot be opened in this manner. The strap can be quickly and easily secured to the buckle without the use of special tools. The strap can also be easily disengaged from the buckle.
