Abstract: A respiratory ventilator is provided. The ventilator comprises a bellows configured to be compressed to deliver a selected tidal volume to a patient. A connecting rod is operably connected to the bellows to compress the bellows by a selected stroke distance that corresponds to the selected tidal volume. A crank arm has an elongated slot into which a pin extends to connect the connecting rod to the crank arm. A control wheel is for selectively adjusting an effective crank arm length. The effective crank arm length directly corresponds to the stroke distance of the connecting rod. The control wheel has a slot into which the pin extends. Selective rotation of the control wheel relative to the crank arm urges the pin to move along an elongated slot of the crank arm toward and away from a drive axis to selectively adjust the effective crank arm length.

Abstract: An exercise with oxygen therapy (EWOT) apparatus for rejuvenating oxygen- depleted cell tissue and simulating high altitude oxygen conditions. The EWOT apparatus includes a first cylindrical bladder for providing oxygen -enriched air and a second bladder for providing lower-purity hypoxic air. The first bladder is retained within an open, lightweight rectangular-shaped frame having vertical frame members. An air supply source provides the oxygen-enriched and hypoxic air to the first and second bladders, respectively. A control switch, which can be manually and/or programmed to automatically operate, selectively delivers the oxygen-enriched and/or hypoxic air to a breathing mask worn by a user while exercising on exercise equipment. The first bladder includes a plurality of weights which provide a positive pressure to the air therein. The cylindrical first bladder is attached to the vertical frame members with slidable rings and expands and collapses in a vertical direction when being filled or during use, respectively.
