The Carbogen Generator allows you to improve health by breathing air supplemented with extra co2. Contributing factors of most disease states are tissue hypoxia which is lack of oxygen. The paradox of oxygen is that the higher the oxygen percentage on the hemoglobin in your blood the less the oxygen will be delivered to your tissues. For oxygen to be delivered to your cells you need adequate levels of co2. The Carbogen Generator allows you to increase the level of co2 breathed in which allows more oxygen to be used by your cells for aerobic respiration which produces more co2 on a cellular level. So supplemental co2 increases your bodies own production of CO2.
