A vented wound dressing barrier includes one or more membrane layers with a plurality of vents. The vents are cut along a perimeter of the vents through the one or more membrane layers. Each vent having a connection portion uncut relative to the one or more membrane layers thereby forming a hinge configured to allow the vents to open for drainage when exposed to fluid underlying the vented wound dressing barrier. The plurality of vents is each cut along the perimeter without removal of any of the membrane layer. The one or more membrane layers with the plurality of vents has a surface for covering a wound, the surface area in the absence of a fluid pressing on the vents having no openings or voids which reduce the surface area of a vented wound dressing barrier area covering a wound.
