Abstract
THE presence of 3-5 per cent of carbon dioxide in the air prevents or alleviates the untoward effects of a low oxygen content (8-9 per cent) on brain stem reflexes and also on vision, muscular co-ordination and mental processes, according to experiments by Prof. E. Gellhorn. The results are interpreted as being due to an improvement in respiration and circulation which leads to a better oxygenation of the brain.
