System and method for managing reduced pressure at a tissue site
First Claim
1. An apparatus for managing reduced pressure at a tissue site, the apparatus comprising:
- a reduced pressure source that generates reduced pressure, the reduced pressure being delivered to the tissue site via a delivery tube;
a single pressure sensor, the single pressure sensor detecting an actual reduced pressure at the tissue site;
a controller, the controller determining a responsiveness of the actual reduced pressure measured by the single pressure sensor to an increase in reduced pressure generated by the reduced pressure source; and
an indicator, the indicator emitting a signal when the controller determines that the actual reduced pressure measured by the single pressure sensor is nonresponsive to the increase in reduced pressure generated by the reduced pressure source.

Abstract
The illustrative embodiments described herein are directed to an apparatus and method for managing reduced pressure at a tissue site. The apparatus includes a reduced pressure source that generates reduced pressure. The reduced pressure is delivered to the tissue site via a delivery tube. The apparatus includes a single pressure sensor. The single pressure sensor detects an actual reduced pressure at the tissue site. The apparatus also includes a controller. The controller determines a responsiveness of the actual reduced pressure measured by the single pressure sensor to an increase in reduced pressure generated by the reduced pressure source. The apparatus includes an indicator. The indicator emits a signal when the controller determines that the actual reduced pressure measured by the single pressure sensor is nonresponsive to the increase in reduced pressure generated by the reduced pressure source.
