Respiratory bypass system: Difference between revisions

The Doctor used it to survive more than once. The [[Second Doctor]] credited his survival on the surface of [[Mnemosyne (moon)|Mnemosyne]] to his respiratory bypass system. ([[PROSE]]: ''[[The Wheel of Ice (novel)|The Wheel of Ice]]'') The [[Fourth Doctor]] 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]]'') [[Fifth Doctor]] used it to survive brief exposure to the [[vacuum|vacuum of space]], ([[TV]]: ''[[Four to Doomsday]]'') to recover from being [[hanging|hanged]] ([[PROSE]]: ''[[A Town Called Eternity]]'') and to retrieve the milk from a [[queen bat]] in an airless cavern. ([[TV]]: ''[[The Caves of Androzani (TV story)|The Caves of Androzani]]'')

The [[Sixth Doctor]] avoided [[hypoxia]] when he shut down atmospheric controls to the mines on the planet [[Onyakis]] to defeat the [[Kroton]]s there, ([[AUDIO]]: ''[[Return of the Krotons]]'') using this advantage again to avoid breathing in [[vorum gas]]. ([[TV]]: ''[[The Two Doctors]]'') In his [[Seventh Doctor|seventh incarnation]], 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]]'') The [[Twelfth Doctor]] was able to remain conscious in a [[Orient Express (spacecraft)|space train]] that was being drained of oxygen long enough to modify a teleportation system to send the train's passengers into the TARDIS ([[TV]]: ''[[Mummy on the Orient Express]]'').
