Body blow

Article Abstract:

A patient admitted to the University Hospital of Wales showed the extreme effects of Valsalva - exhaling forcefully without opening the glottis. While blowing up 20 balloons, pockets of air developed under the patient's skin as air leaked from ruptured air sacs in his lungs into the surrounding tissues.
