Claim 50:
51. A method of applying reduced-pressure to a tissue interface of a dressing and sensing properties of fluids at a tissue site for treating the tissue site, the method comprising:
positioning a dressing interface on the tissue interface, the dressing interface having a housing including an outside surface and a therapy cavity disposed between the outside surface and an opening configured to be in fluid communication with the tissue interface, and wherein the dressing interface further comprises:
a port fluidly coupled to the therapy cavity and adapted to fluidly couple a reduced-pressure source to the therapy cavity, and
a pH sensor and a pressure sensor disposed within the therapy cavity and each electrically coupled to a control device; and

applying reduced pressure to the therapy cavity to draw fluids from the tissue interface into the therapy cavity;
sensing a pH and a pressure of the fluids within the therapy cavity utilizing the pressure sensor and the pH sensor;
providing fluid data indicative of the sensed pH and the sensed pressure to the control device; and
processing the fluid data for presenting information for treating a tissue site.
