What is the primary purpose of Controlled Compression Therapy (CCT) units?

• A. Increase arterial blood flow
• B. Decrease blood flow to an extremity and assist venous return, decrease edema, and increase the effective depth of cold penetration.
• C. Heat tissue to promote healing
• D. Increase edema and inflammation

Answer: (B)

Controlled Compression Therapy units combine controlled limb compression with cold therapy to manage tissue edema. The main goal is to move excess fluid out of the injured area by boosting venous and lymphatic return and by mechanically helping push interstitial fluid away from the tissues. The cold component also reduces metabolic demand and causes vasoconstriction, which helps limit further swelling. An added benefit is that the compression improves contact with the cold source and can help the cold penetrate deeper into the tissue. So, the primary purpose is to decrease edema and assist venous return, with the improved depth of cold penetration as a helpful side effect. The other options don't fit because CCT uses cold, not heat; its aim isn’t to increase arterial blood flow or to raise edema and inflammation.
