An apparatus for a fan includes control means (108) configured to receive status information indicative of a pressure that is greater than or less than at least one predetermined threshold pressure at least one level. a pressure switch (208), and controlling an air movement device to repeatedly inflate the patient's lungs and allow deflation, based on at least the received state information. In use, the at least one pressure switch is placed at a pressure representative of an air pressure in the lungs (202) of a patient. The state information does not include an absolute digital pressure value at the at least one pressure switch. |
