Which two parameters are most effective in healing venous ulcers with compression systems?

The most effective parameters for healing venous ulcers with compression systems are multilayer systems and high compression. Multilayer compression systems are designed to apply graduated compression, which means that the pressure is highest at the level of the ankle and decreases as it moves up the leg. This design effectively promotes venous return, reduces edema, and alleviates symptoms associated with venous insufficiency.

High compression is essential because it ensures sufficient pressure to overcome the increased venous pressure that occurs in patients with venous ulcers. Studies show that adequate compression improves healing rates by creating a favorable environment for ulcer closure.

In contrast, single-layer systems and low compression may not provide the necessary pressure to manage the underlying venous hypertension effectively. Multilayer systems have the added benefit of distributing pressure evenly and accommodating changes in limb size or shape, which can occur due to fluid changes in the tissues. Therefore, combining the multilayer design with high compression yields the best outcomes in the treatment of venous ulcers.
