The sleeve has multiple chambers that fill with the air sequentially, distally to proximally (from your foot toward your hip). ^ Smith SF, Biggs MT, Sekhon LH (2005). The SCD is a machine that pumps air into a sleeve that goes around your leg."Intermittent Pneumatic Compression and Preventing Deep Vein Thrombosis & Pulmonary Embolism". "Prevention of VTE in Nonorthopedic Surgical Patients: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines". ^ Gould MK, Garcia DA, Wren SM, Karanicolas PJ, Arcelus JI, Heit JA, Samama CM (2012).Intraoperative SCD-therapy is recommended during prolonged laparoscopic surgery to counter altered venous blood return from the lower extremities and consequent cardiac depression caused by pneumoperitoneum (inflation of the abdomen with carbon dioxide). 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 low molecular weight heparins or unfractionated heparin. 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. The intermittent compressions of the sleeves will ensure the movement of venous blood. The primary functional aim of the device "is to squeeze blood from the underlying deep veins, which, assuming that the valves are competent, will be displaced proximally." When the inflatable sleeves deflate, the veins will replenish with blood. A short time later, the pressure is reduced, allowing increased blood flow back into the limb. 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. The most notable crossover was NormaTec, a solution that stemmed. 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. Like many recovery products in sport, most compression systems originated as medical devices. Intermittent pneumatic compression is a therapeutic technique used in medical devices that include an air pump and inflatable auxiliary sleeves, gloves or boots in a system designed to improve venous circulation in the limbs of patients who have edema or the risk of deep vein thrombosis (DVT), pulmonary embolism (PE), or the combination of DVT and PE which is venous thrombeombolism (VTE). ![]()
