SCD stands for Sequential Compression Device. This medical device uses inflatable leg sleeves connected to a controller that inflates in sequence, usually from the ankle upward. The sequential inflation mimics the natural calf muscle pump, enhancing venous return, reducing blood stasis, and helping prevent deep vein thrombosis in patients who are immobile or recovering from surgery. The other terms listed aren’t standard names for this device, so the sequential compression mechanism is what defines SCD.
