1. A vented chest wound seal for a penetrating chest wound comprising:
- a flexible sheet including a top surface and a bottom surface and a vent hole extending through the flexible sheet from the top surface to the bottom surface; and
a non-rigid adhesive layer covering a portion of the bottom surface of the flexible sheet, the adhesive layer including an inner perimeter and an outer perimeter, the inner perimeter defining a chamber;
including;
a vent channel extending radially outward from a central portion of the chamber to an outer terminal end, wherein the outer terminal end is within the outer perimeter of the non-rigid adhesive layer,wherein the vent hole is aligned over the vent channel such that the vent hole and the vent channel form a straight-line pathway extending from the top surface of the flexible sheet through the vent channel in the adhesive layer; and
a continuous perimeter of hydrogel along a bottom surface of the adhesive layer entirely surrounding the inner perimeter.
