Hypercapnic hypoxia as a potential means to extend life expectancy and improve physiological activity in mice.

The application of combined hypoxia and hypercapnia (hypercapnic hypoxia) during respiratory exercises results in a maximum increase in resistance to acute hypoxia and ischemic tolerance of the brain. The results of those researches allow the assumption that hypercapnic hypoxia is a promising method for prophylaxis, treatment, and rehabilitation, as well as a means to increase life expectancy. The study was conducted to verify the hypothesis that it is possible to extend the life span through regular courses of respiratory exercises with hypercapnic hypoxia.
