Claim:
1. An oxygen-delivery wound treatment device, the device comprising: a) a formed biocompatible matrix, wherein the matrix is a closed cell foam, the matrix comprising: a cross-linked polymer present in an amount ranging from about 2.5 wt. % to 10 wt. % based on the total weight of the matrix and a non-gellable polysaccharide present in an amount ranging from 0.25 wt. % to 5 wt. % based on the total weight of the matrix, wherein the cross-linked polymer comprises polyacrylamide cross-linked with 0.025 wt. % to 0.15 wt % bis-acrylamide based on the total weight of the matrix and the non-gellable polysaccharide comprises guar gum, wherein the matrix includes closed cells and walls; b) gaseous oxygen, wherein the gaseous oxygen is contained in the closed cells; c) dissolved oxygen, wherein the dissolved oxygen is present in the walls, wherein the gaseous oxygen and the dissolved oxygen are formed by a reaction between a peroxide and a catalyst; and d) water, wherein the water is present in the walls, wherein the oxygen delivery wound treatment device delivers oxygen to a wound site or compromised tissue.
