How does the use of compression devices benefit postoperative patients?

The use of compression devices significantly benefits postoperative patients by helping prevent clot formation in the legs. After surgery, patients are often less mobile and may have limited blood flow in their lower extremities due to immobility, which can increase the risk of venous thromboembolism (VTE), including deep vein thrombosis (DVT). Compression devices work by applying regulated pressure to the legs, which enhances venous blood flow back to the heart. This increased circulation helps to mitigate the risk of clot formation by preventing blood from pooling in the veins and encourages more effective blood flow throughout the lower extremities.

The other options do not accurately describe the primary benefits associated with compression devices. While they may indirectly assist with wound healing or reduce inflammation, their main intended role is specifically focused on the prevention of clots in the legs. Additionally, compression devices do not influence the cough reflex, which is a function of the respiratory system.
