How much pressure is typically necessary to control lower extremity edema with compression garments?

To effectively control lower extremity edema, compression garments generally require a pressure range that is adequate to create a physiological response in the tissues. A pressure of 35 mmHg is typically necessary for managing significant edema in the lower extremities. This level of compression is sufficient to promote venous return and reduce swelling by preventing the accumulation of interstitial fluid.

Compression at this level helps in enhancing lymphatic drainage and venous circulation, which is particularly crucial for individuals with conditions that predispose them to edema, such as venous insufficiency or post-surgical swelling.

Lower pressures, such as 10 mmHg, 18 mmHg, or even 25 mmHg, may not provide the necessary compression to achieve these outcomes, as they might be too low to effectively counteract the forces contributing to fluid accumulation. Therefore, the use of a compression level around 35 mmHg is most effective in addressing and managing lower extremity edema.
