1. An apparatus for relieving dyspnoea in a subject, the apparatus comprising:

  • an air supply means for providing an air supply at a pressure greater than ambient for delivery to the subject, a monitoring means for monitoring at least a part of at least one breathing cycle of the subject for determining an intrinsic positive end-expiratory pressure of a breathing cycle of the subject, a control means responsive to the monitoring means for controlling the pressure of the air supply delivered to the subject during an expiratory part of the breathing cycle at a pressure similar to the determined intrinsic positive end-expiratory pressure, and;

    a computing means for determining an average intrinsic positive end-expiratory pressure based on the intrinsic positive end-expiratory pressure monitored by the monitoring means over a plurality of breathing cycles, and the control means is responsive to the monitoring means for controlling the pressure of the air supply delivered to the subject during the expiratory part of each breathing cycle at a pressure similar to the determined average intrinsic positive end-expiratory pressure.
