Abstract
A negative pressure wound therapy system can include a negative pressure source configured to provide, via a fluid flow path, negative pressure to a wound covered by a wound dressing. The system can include a controller. The controller can be configured to periodically activate the negative pressure source to maintain negative pressure in the fluid flow path between a low negative pressure setpoint and a high negative pressure setpoint. The controller can be configured to determine a change in a volume of the wound based on a difference between a first time and a second time at which the high negative pressure setpoint has been established in the fluid flow path, the second time being subsequent to the first time. The controller can be configured to provide indication of the change in the volume of the wound.
