Claim 60:
61. A method of applying reduced-pressure to a tissue interface and sensing properties of fluids at a tissue site for treating the tissue site, the method comprising:
positioning a dressing interface at 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, the dressing interface further comprising:
a reduced-pressure port fluidly coupled to the therapy cavity and adapted to fluidly couple a reduced-pressure source to the therapy cavity,
a vent port fluidly coupled to the therapy cavity and adapted to fluidly couple a source of airflow 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 the pH and pressure properties of the fluids within the therapy cavity utilizing the pressure sensor and the pH sensor; and
venting airflow into the therapy cavity to purge the fluids from the therapy cavity out of the reduced-pressure port.
