The device has a breathing tube () for connection to a patient, and a pressure sensor () adapted to determine the pressure within the breathing tube. A valve () selectively connects the breathing tube to the inlet side or the outlet side of the pump whereby to provide cycles of positive and negative pressure within the breathing tube. A controller () is provided to control the valve.
