Loss of Interface Pressure in Various Compression Bandage Systems over Seven Days

BACKGROUND: Manufacturers' instructions of multi-component compression bandage systems inform that these products can remain up to 7 days during the therapy of venous leg ulcer. This implies that the pressure needed will be sustained during this time. OBJECTIVE: The present research investigated the persistence of pressure of compression systems over 7 days. METHODS: All 6 compression systems available in Germany at the time of the trial were tested on 35 volunteering persons without signs of venous leg disease. Bandaging with short-stretch bandages was included for comparison. Pressure was measured by using PicoPress®. RESULTS: Initially, all products showed sufficient resting pressure of 40 mm Hg checked with a pressure monitor, except for one system in which the pressure fell by at least 23.8%, the maximum being 47.5% over a period of 7 days. CONCLUSION: The currently available compression systems are not fit to keep the required pressure. Optimized products need to be developed.
