What are the effects of external compression?

• Effects will vary depending upon the compression device used and the amount of pressure applied • Intermittent may improve circulation more so than static pressure because it produces a "milking" of the fluids from distal to proximal. When venous and lymphatic vessels are compressed, the fluids within these vessels is forced proximally. When the compression is reduced, fluid again fills the spaces outside the vessels. Sequential intermittent compression is believed to be more effective than non sequential because of the "wave" like formation. • This improved circulation benefits patients with edema, helps prevent the formation of dvt's and may facilitate the healing of wound ulcers cause by venous disease. • Compression can help shape a limb or residual limb (post amputation or extensive scarring, for example) • Increases skin temperature
