Abstract: A negative pressure wound therapy device can be configured to monitor motion and determine that the device is falling as well as duration and height of the fall. Flat falls and rotating falls can be accurately detected. The device can provide an indication of the fall, including deactivating therapy. The device can monitor the amount exudate removed from a wound and determine whether transition to a low-exudate rate negative pressure wound therapy and suggest such transition. The device can utilize proportional-inte-gral-derivative (PID) control loop to drive a negative pressure source of the device. The PID control loop can utilize different proportional gain and integral gain for different negative pressure setpoint to achieve target pressure quickly and without any large overshoots.
