A New Hope for Long Space Flights: Hypercapnia demonstrated suppression of metabolic acidosis in an experiment with prolonged stay of people in a closed life support system
Abstrak
Humanity must solve the problems that threaten human health during long-term space flight. An unexpected solution is suggested by an experiment on people staying in a closed life support system model, conducted more than 50 years ago in Krasnoyarsk. The high level of carbon dioxide established after the start of the experiment changed the metabolism of the inhabitants. We present the interpretation of the results of the Krasnoyarsk experiment through understanding the effect of hypercapnia on metabolism for the first time in this work. Hypercapnia suppressed the possibility of developing metabolic acidosis and activated fat oxidation. The change in the respiratory quotient caused by hypercapnia stabilized the composition of the gas mixture in the closed life support system and ensured the stability of the system.
