1. A wound therapy apparatus comprising:
a negative pressure source configured to provide negative pressure via a fluid flow path to a wound of a patient covered by a wound dressing and to remove fluid from the wound;
a pressure sensor configured to monitor pressure in the fluid flow path; and
a controller programmed to:
monitor a rate of fluid removal from the wound during provision of negative pressure by the negative pressure source by monitoring pressure variations in the fluid flow path using an output of the pressure sensor,
determine that the rate of fluid removal causes a first volume of fluid being removed from the wound to equal to or exceed a second volume of fluid being provided to the patient, and
provide a notification responsive to determining that the rate of fluid removal causes the first volume of fluid to equal to or exceed the second volume of fluid.
