A cavity model was used to simulate the fluid transfer capability of Exufiber^® and Aquacel^® ribbon dressings. 5ml of Solution A was added to the cavity and the dressings were left to absorb and transfer. An additional 5ml was then added and the dressings left to absorb and transfer again. Exufiber^® demonstrated a better capability to transfer fluid to the secondary dressing than Aquacel^®, and when the dressings were removed, less fluid was left in the cavity  .
