What level of compression is considered therapeutic?

1. 10-20 mmHg

2. 20-30 mmHg

3. 30-42 mmHg

4. 42-60 mmHg

The correct answer is: 30-42 mmHg

The range of 30-42 mmHg is recognized as therapeutic compression because it is generally considered effective for managing conditions like venous insufficiency, edema, and chronic venous disorders. This level of compression promotes blood flow back to the heart, decreases swelling, and helps in the prevention of complications such as venous ulcers. Compression of this magnitude can effectively support the venous system by exerting pressure on the veins, thereby improving venous return and reducing pooling of blood in the lower extremities. Additionally, 30-42 mmHg compression may be particularly beneficial in cases of moderate to severe symptoms or when higher levels of support are required due to patient-specific factors. In contrast, lower levels of compression (for example, 10-20 mmHg) are typically used for mild swelling or to prevent deep vein thrombosis (DVT). Levels above 42 mmHg may be more suitable for specialized cases or might be contraindicated for certain patients due to risks of impaired blood flow. Thus, the therapeutic range in question is critically viewed within the scope of wound care practice, making it essential to understand the appropriate application for optimal outcomes.
