Abstract
A wound dressing is selectively configurable for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system. The wound dressing can include a pressure distribution layer and a covering layer. The covering layer includes an indicia, the indicia denoting the optimal position in the covering layer to create an aperture to provide fluid communication between the pressure distribution layer and a source of non-atmospheric pressure.
