1. A negative pressure wound therapy apparatus, comprising:

  • a negative pressure source configured to be in fluid communication with a wound dressing configured to be positioned over a wound;

    a canister configured to be in fluid communication with the wound dressing and the negative pressure source via a fluid flow path, the canister configured to collect exudate aspirated from the wound;

    a pressure sensor configured to monitor one or more characteristics of pressure signals generated by the negative pressure source in the fluid flow path, the one or more characteristics of the pressure signals comprising magnitude of the pressure signals, the magnitude of the pressure signals increasing as a level of exudate in the canister increases; and

    a controller configured to;

    determine a pressure threshold based at least on a pressure setting for the negative pressure source and a level of activity of the negative pressure source, andindicate that the canister is full of exudate in response to determining that the magnitude of the pressure signals satisfies the pressure threshold.
