The Pneumatic Anti-Shock Garment (PASG), also called Medical (Military) Anti-Shock Trousers (MAST).
It is shown ready for use with the two leg compartments (on right) and the abdominal wrap (on left). The air bladders are connected to the foot pump (black circular element) and a gauge with a relief valve which limits the pressure to 104 mm Hg above ambient pressure.
The pressure during pumping up is distributed evenly and does not act from proximal to distal as required for displacing blood into the central circulation.
