In a method of providing a supply of breathing gas under pressure for breathing by a user, the steps comprising: providing a flow of such breathing gas through a supply path which extends from a breathing gas source to the airway of the user; maintaining a varying pressure of said breathing gas flow within said supply path at selected elevated pressures which vary in magnitude over a given time interval; and passing an essentially continuous exhaust flow of said varying pressure breathing gas from said supply path to ambient pressure at an essentially constant flow rate throughout said given time interval.
