Abstract : Physiological tests were made on the M.S.A. Type E Experimental Oxygen Mask. It was found that the allchamois lining mask fitted perfectly 86 out of 102 men during rest. This mask was comfortable. The other two types, part-chamois and no-chamois, gave a larger number of failures. They were not as comfortable as the all-chamois mask. There was good integration with 'the standard helmet but not with the goggles. The supporting straps and holders are of poor construction. The upper lip strap stretches out of shape. There is a high resistance to expiratory flow. The mask has very good characteristics in the cold. (Author)
