1. An apparatus for managing fluid in a system for treating a tissue site, the apparatus comprising:
a top layer including a polymeric film having a plurality of cells having closed ends extending from a surface of the top layer;
a base layer including a polymeric film coupled to the top layer to form a seal around a perimeter of the top layer and the base layer, wherein the seal forms an enclosed space between the top layer and the base layer containing the plurality of cells;
an applicator at one end of the enclosed space having an aperture formed in the base layer, wherein the aperture exposes a portion of the plurality of cells to define a recessed space adapted to be fluidly coupled to the tissue site;
a bridge extending from the applicator to the other end of the enclosed space and forming a port at the other end of the enclosed space; and
a first barrier and a second barrier coupled between the top layer and the base layer to form three fluid pathways within the enclosed space in fluid communication between the port and the recessed space.
