title: The pneumatic antishock garment: use in experimental acute cardiac tamponade.
abstract: Acute cardiac tamponade was created in a large animal model in an effort to investigate the hemodynamic and oxygen transport variables during the inflation of the pneumatic antishock garment (PASG) to two different pressures (60 and 80 mm Hg). Inflation of PASG to either pressure under these conditions had no significant effects on filing pressures to the right or left heart, cardiac index, arterial blood gases, oxygen delivery, indexed pulmonary, and systemic vascular resistances. We conclude in this animal model of acute cardiac tamponade that no beneficial or harmful effects were demonstrated during the application and inflation of the pneumatic antishock garment to 60 or 80 mm Hg.
