There are numerous case reports of APL valve trapping with old Draeger APL valves leading to an inability to ventilate which is often undiagnosed until later (by then it may be too late). Draegers newer design of APL valve has a bevel which minimises the risk of this happening. We want Draeger to recall and replace their old APL valves for patient safety.
