Reduction of false alarms during provision of negative pressure wound therapy

A negative pressure wound therapy system comprising:

• a negative pressure source configured to provide, via a fluid flow path, negative pressure to a wound covered by a wound dressing;
• a pressure sensor configured to measure a pressure in the fluid flow path;
• a user interface configured to receive input from a user and provide a plurality of notifications to the user;
• a first processor configured to operate the negative pressure source based on the pressure in the fluid flow path and detect an operating condition associated with provision of negative pressure;
• and
• a second processor configured to verify detection of the operating condition by the first processor and provide a notification of the operating condition by:
• upon expiration of a first time duration, receiving from the first processor an indication that the operating condition has been detected during the first time duration;
• and
• via the user interface, providing the notification of the operating condition to the user in response to verifying that a plurality of indications have been received from the first processor during a second time duration that spans a plurality of first time durations.
