Abstract
A dressing includes an evaporative film layer having a wound-facing side and a non-wound¬ facing side. The evaporative film layer has a high moisture vapor transfer rate. The dressing includes a carrier film layer coupled to the non-wound-facing side of the evaporative film layer. A plurality of holes extends through the carrier film layer. The dressing includes a superab sorbent layer coupled to the wound-facing side of the evaporative film layer and a wicking layer coupled to the superab sorbent layer. The superab sorbent layer is positioned between the wicking layer and the evaporative film layer. The wicking layer is configured to wick fluid from a wound, the superab sorbent layer is configured to absorb fluid from the wicking layer, and the evaporative film layer and the carrier film layer allow evaporation of fluid from the superabsorbent layer through the holes. The carrier film layer provides structural support to the evaporative film layer.
