What is the MVTR (Moisture Vapour Transmission Rate) of the dressing/top liner?
For highly exuding wounds when the film top liner is removed the MVTR of the dressing is 3000 gm/m2 over 24 hours. This is the equivalent of the MVTR of a highly effective film dressing, thus allowing good fluid handling properties. Fluid handling is the amount absorbed by the dressing plus the amount of fluid that passes through the back of a dressing as moisture vapour (Bishop 2003). However, the MVTR is affected by a cover dressing or bandage.
