What is the purpose of using sequential compression devices (SCDs)?

• A. To prevent thrombus formation in immobile patients.
• B. To promote weight loss.
• C. To increase circulation but not prevent clots.
• D. To monitor oxygen saturation.

Answer: (A)

The key idea is preventing venous thromboembolism in people who are immobile by improving venous return. Sequential compression devices work by applying intermittent pressure to the legs in a distal-to-proximal sequence, which mimics the natural muscle pump. This action reduces venous stasis in the deep veins of the legs, lowering the risk that clots will form and potentially travel to the lungs as a pulmonary embolism. They’re specifically about preventing clots, not about weight loss or monitoring oxygen saturation. So, the best answer is that their purpose is to prevent thrombus formation in immobile patients.
