sequential compression deviceAbbreviation: SCD.
A device to reduce edema or prevent the formation of blod clots in an extremity. A chambered nylon sleeve is progressively inflated from its distal segment to the proximal segment, forcing venous and lymphatic return. Sequential compression devices are inflated with air (pneumatic compression) or, less commonly, chilled water (cryocompression). SCDs are used frequently in the perioperative period.
