Compression garments used to prevent deep vein thrombosis in bedridden patients typically apply what pressure?

• A. 16-18 mmHg
• B. 30-40 mmHg
• C. 8-12 mmHg
• D. 24-32 mmHg

Answer: (A)

External gradient compression from stockings is designed to boost venous return and reduce venous pooling in the legs. The pressure is highest at the ankle and tapers up the leg, gently squeezing the calf veins to push blood back toward the heart. For bedridden patients, a moderate level of compression is used to lower the risk of deep vein thrombosis without compromising arterial blood flow or causing skin irritation. The typical prophylactic range is about 16-18 mmHg, which provides enough assist to venous return while remaining comfortable and safe for most individuals. Higher pressures, such as 30-40 mmHg, are unnecessary for this purpose and can increase the risk of vascular or skin problems, while too-low pressures like 8-12 mmHg may not sufficiently counteract venous stasis.
