Purpose : Evaluate the safety and relative effects of different cuff pressure combinations to determine if edema reduction was dose-dependent.

Results : A dose-response relationship was observed between increased SPC/IPC pressures and reduced limb edema. Limb volume was reduced most effectively with the highest pressures of 40-mm Hg nongraduated SPC and 60-mm Hg graduated IPC (136 mL and 87 mL, respectively); however, some subjects reported discomfort with these profiles. Limb volume was reduced by more than 100 mL with 30 to 40-mm Hg graduated SPC and by 69 mL with 50-mm Hg graduated IPC, and subjects rated these profiles as comfortable or very comfortable. Of the 28 study participants (12 SPC, 16 IPC), two subjects reported pain with 60-mm Hg IPC; no other adverse events were reported with SPC or IPC.

Conclusions : Pneumatic compression was safe and well-tolerated, with a dose-response relationship between increased SPC/IPC pressures and reduced leg edema. To our knowledge this is the first study to demonstrate a dose-relationship in compression therapy: higher pressures are associated with greater volume reduction in subjects with chronic venous edema.
