The average rate of living space set 9 meters per person. It is calculated from the volume of air that must be about 30 m3 / h At a height of about three meters of space and a single exchange of air oxygen will override human needs. In child care for one child under school age should have to air 10 m3 at three exchanges, in elementary school, too, with 20 m3 triple exchange.
Children are very sensitive to the decrease in the concentration of oxygen and increased carbon dioxide in the air. In case of violation of oxygen exchange, they begin to act up, they note falls, reduced immunity. Adults resist anoxia more active external symptoms have fewer, but more dangerous than the deep structural changes.
