ABSTRACT:
A respiratory exerciser and rebreathing device in which inhalation and exhalation chambers are provided for mixing exhaled air with ambient air to increase the carbon dioxide content of the air to be inhaled. A mouthpiece and a valve device between the mouthpiece and the chambers for directing the air flow are provided, and an adjustable mechanism is used to vary the amount of exhaled air which is mixed with ambient air to be rebreathed. Condensation plates in the inhalation chamber remove moisture from the air which is inhaled. The breathing pressures required to operate the device may be variable, in order to control the exercise of the muscles of respiration.
