MAST Trousers

MAST (military anti-shock trousers)

MAST trousers are a medical device that was initially designed to provide auto transfusion by compression of the abdomen and lower extremities.
Since it development there has been little evidence to support claims that this device actually auto transfused or improved mortality in patients suffering from hypovalemia.
Improvement in blood pressure is thought to be secondary to increased peripheral vascular resistance.
