A respiratory bypass system was a part of Gallifreyan physiology which allowed Time Lords to go without breathing for longer periods of time than most humans could. (AUDIO: Return of the Krotons) It also allowed them to filter out unpleasant smells. (PROSE: Cat's Cradle: Witch Mark)

The Doctor used it to survive more than once. The Doctor's fourth self used his respiratory bypass system to survive being strangled by an Osirian service robot. (TV: Pyramids of Mars) He later used it to avoid inhaling helium. (TV: The Robots of Death) The fifth incarnation used it to survive brief exposure to the vacuum of space (TV: Four to Doomsday) as well as being hanged (PROSE: A Town Called Eternity) and retrieving the milk from a queen bat in an airless cavern. (TV: The Caves of Androzani) His sixth persona avoided hypoxia when he shut down atmospheric controls to the mines on the planet Onyakis to defeat the Krotons there (AUDIO: Return of the Krotons), using this advantage again to avoid breathing in nerve gas. (TV: The Two Doctors) In his seventh body, the Doctor used his respiratory bypass system to avoid being overcome by ether. (PROSE: Timewyrm: Genesys) His eleventh incarnation survived the vacuum of low earth orbit long enough to find and put on an impact suit -- backwards. (TV: The Doctor, the Widow and the Wardrobe)

At least one human may have developed such a system: Timothy Dean, who gained one when he was infected with the Seventh Doctor's DNA. (PROSE: Human Nature)
