What does compression therapy do for patients with LEVD?

1. Decreases interstitial pressures

2. Increases interstitial tissue pressures

3. Promotes blood clots

4. Relaxes the veins

The correct answer is: Increases interstitial tissue pressures

Compression therapy plays a vital role in the management of patients with Lower Extremity Venous Disease (LEVD) by increasing interstitial tissue pressures. This increase serves several important functions; it helps to reduce the accumulation of excess interstitial fluid, thereby decreasing swelling and edema often associated with venous conditions. By applying external pressure, compression garments enhance venous return and prevent the pooling of blood in the lower extremities. In this context, when interstitial pressures are elevated, it effectively counteracts the hydrostatic forces that contribute to fluid leakage from the capillaries into the interstitial space. This mechanism not only improves lymphatic function but also promotes better overall circulation, which can significantly alleviate symptoms and improve the quality of life for patients suffering from LEVD. Overall, the primary goal of employing compression therapy is to support venous function by stabilizing the interstitial environment, thus enhancing overall venous health.
