When Bruce Anderson arrives at the hospital, he is wearing MAST (Medical Anti-Shock Trousers) aka PASG (Pressurized Anti-Shock Garment) and the doctor opens the Velcro fly on them to examine his injuries. Developed during the Vietnam war era to help combat shock caused by blood loss to the core (such as through hypovolemia) by pushing blood out of the legs and into vital organs by inflating air pockets in the "pants", MAST was commonly used into the 1980's for trauma patients. However, concerns about clot rupture and vascular damage, combined with inconsistent benefits to patients that have injuries above the waist, have reduced the use of MAST at present.
