What is a therapeutic level of compression recommended at the ankle for LEVD?

1. 10-20 mmHg

2. 20-30 mmHg

3. 30-40 mmHg

4. 40-50 mmHg

The correct answer is: 30-40 mmHg

The therapeutic level of compression recommended at the ankle for lower extremity venous disease (LEVD) is indeed in the range of 30-40 mmHg. This level of compression is effective in managing venous insufficiency and promoting venous return, ultimately helping to reduce symptoms such as swelling and discomfort. In individuals with LEVD, appropriate compression helps support the venous system by applying external pressure to the limb, which can aid in preventing venous stasis and the progression of venous ulcers. Compression levels in the 30-40 mmHg range are commonly used for moderate to severe conditions where there is significant fluid accumulation or varicosities. Lower levels of compression, such as 10-20 mmHg or 20-30 mmHg, may not provide sufficient pressure to counteract the elevated venous pressures typically seen in patients with more advanced venous disease. Conversely, higher levels of compression at 40-50 mmHg may be too restrictive for some patients, potentially leading to discomfort or contraindications in certain populations. Therefore, the selected range of 30-40 mmHg strikes a balance, making it the recommended therapeutic choice for managing LEVD effectively.
