Beard Length and the Efficacy of an Aviator Oxygen Mask

Using a current on-demand airline oxygen mask, Spo2 levels were never compromised by any of the beard conditions. Because the highly volatile smelling salts were imperceptible through the masks, smoke and other noxious irritants would not be perceived. These results support the contention that airline pilots with beards of any length would not be impaired by hypoxia or smoke while dealing with an in-flight emergency. French J, Wagner SD.
