(VTE). In use, an inflatable jacket (sleeve, glove, trousers or boot) encloses the limb requiring treatment, and pressure lines are connected between the jacket and the air pump. When activated, the pump fills the air chambers of the jacket in order to pressurize the tissues in the limb, thereby forcing fluids, such as blood and lymph, out of the pressurized area. A short time later, the pressure is reduced, allowing increased blood flow back into the limb. The primary functional aim of the device "is to squeeze blood from the underlying deep veins, which, assuming that the valves n your veinsare competent, will be displaced proximally." When the inflatable sleeves deflate, the veins will replenish with blood. The intermittent compressions of the sleeves will ensure the movement of venous blood.

Sequential compression devices

Sequential compression devices (SCD) utilize sleeves with separated areas or pockets of inflation, which works to squeeze on the appendage in a "milking action." The most distal areas will initially inflate, and the subsequent pockets will follow in the same manner. Sequential calf compression and graduated compression stockings are currently the preferred prophylaxis in neurosurgery for the prevention of DVT and pulmonary embolism, sometimes in combination with
