Abstract
AbstractThe biochemical mechanisms of oxygen poisoning are discussed together with the signs and symptoms produced clinically. Investigation of 35 subjects performing work (mean 02 consumption 1.4 l./min) for 40 minutes in a pressure chamber at simulated depths of 20 to 47 feet of sea water showed that this degree of exercise markedly reduced the oxygen exposure tolerance of the subjects. This investigation also showed that rapid decompression of subjects breathing oxygen can produce an exacerbation of existing symptoms and these results are discussed.It is stressed that any breathing mixture containing a partial pressure of oxygen in excess of 150 torr constitutes an environment which is hyperbaric with respect to oxygen and caution is advised in the administration of oxygen to any patient.
