Abstract
Apparatus ( ) for relieving dyspnoea in an ambulatory exercising subject comprises a housing ( ) to be worn on the subject, and within which a variable speed air blower motor ( ) is located for delivering an air supply to the subject through a mouthpiece ( ) at a pressure similar to average intrinsic positive end-expiratory pressure of the subject. A pressure transducer ( ) in the mouthpiece ( ) monitors the pressure during breathing cycles of the subject, and a control circuit ( ) determines the average intrinsic positive end-expiratory pressure of the subject over five breathing cycles. The control circuit ( ) operates the air blower motor ( ) for delivering the air supply to the subject at a pressure similar to the determined average intrinsic positive end-expiratory pressure.
