Compression therapy is most clearly indicated for edema that stems from problems with the venous or lymphatic systems. Phlebolymphostatic edema arises from venous insufficiency and venous hypertension, so external pressure helps by increasing tissue pressure, improving venous return, and reducing fluid leakage into the tissues. Lymphedema is due to impaired lymphatic transport, and compression supports lymphatic drainage and lowers swelling. Lipedema, while involving fatty tissue with edema, often responds to compression by reducing the accumulating fluid and providing better leg contour and comfort. In contrast, acute cellulitis involves an active infection in the skin and soft tissues, so applying compression is generally avoided until the infection is treated, as pressure can aggravate inflammation or hinder healing. Severe arterial disease means reduced blood flow to the tissues, and compression can further compromise perfusion, making it unsafe. Cardiac edema from heart failure is not a primary indication for compression; managing the underlying heart condition takes precedence, with compression used cautiously and typically only after medical clearance.
