1. A system comprising:
a dressing for facilitating delivery of oxygen to a target tissue, the dressing comprising:
a first manifold that defines a plurality of gas passageways and is configured to allow communication of oxygen to the target tissue;
a gas-occlusive layer configured to be disposed over the first manifold and coupled to tissue surrounding the target tissue such that an interior volume is defined between the gas-occlusive layer and the target tissue; and
the gas-occlusive layer limits escape of oxygen from the interior volume between the gas-occlusive layer and the tissue surrounding the target tissue;
a container outside the interior volume, the container having a sidewall that defines a chamber configured to be in fluid communication with the interior volume;
one or more capsules, each of which define a pocket that includes water, the one or more capsules disposed within the chamber of the container; and
an oxygen-generating material disposed within the chamber of container and configured to release oxygen when exposed to water.
