A reduced-pressure treatment system for treating a tissue site of a patient,the system includes a manifold pad fordisposing proximate the tissue site. The manilfold pad includes a hydrogelreservoir member and a manifold member. The hydrogelreservoir member is adapted to receive and store fluid from the tissue site ata first pressure and adapted to release at least aportion of the fluid at a second pressure. The first pressure is greater thanthe second pressure on an absolute pressure scale. Thesystem also includes a sealing drape for placing over the tissue and manifoldpad. The sealing drape forms a fluid seal over thetissue and manifold pad. A reduced-pressure subsystem delivers reducedpressure to the sealing drape. Other systems, apparatuses,and methods are disclosed.
