ABSTRACT:
A device for exercising respiratory muscles. By creating a cavity within its bottle like body, the device is able to trap a sufficient amount of exhaled CO.sub.2, to prevent a subject from experiencing the effects of hyperventilation as the subject inhales and exhales at high and large respiratory rates and volumes respectively. The invention has at one end a face mask, which is fastened to a bottle like body. This bottle like body can be enlarged or reduced to create a varying size cavity that traps exhaled CO.sub.2 and ambient air. An opening is placed at or near the bottom of the device that allows ambient air to enter the cavity. The opening is large enough so that no resistance of air flow is experienced during breathing exercise, as resistance of air flow may be damaging to lung tissue. The bottle like body which creates the cavity is divided into upper and lower halves. These halves slide or twist, one within the other to increase or decrease the size of the cavity, in order to accommodate differing lung capacities.
