Abstract: A treatment system includes an dressing having a decompression layer and an occlusive layer that secures the dressing about a treatment site, and defines a treatment chamber within which the decompression layer is positioned. Operation of an air displacement device fluidly coupled to the chamber causes the decompression layer to compress away from the tissue site, resulting in a pulling force being imparted onto the treatment site. This decompression of the tissue site increases the perfusion of blood and other fluids, and advantageously may reduce swelling at the treatment site. To increase the degree of lifting of the treatment site, the decompression layer is advantageously constructed to exhibit a parallel plate effect during use of the treatment system. For example, the decompression layer is constructed having a center of stiffness located closer to an outwardly-facing surface of the decompression layer than a tissue-facing surface of the decompression layer.
