Abstract
The present invention relates generally to the field of breathing exercise devices and more particularly to expiratory breathing methods which promote proper resistance breathing by the user. More specifically, the present invention discloses a method which utilizes a pressure relief valve, preferably a positive end-expiratory pressure (PEEP) valve, for providing positive expiratory pressure (PEP). The PEP is provided by obstructing the flow of gases exhaled by the patient through the PEEP valve, so that such gases must be exhaled against the PEEP valve's pressure threshold.
