Air corridor
From Tardis Wiki, the free Doctor Who reference
An Air Corridor was a type of corridor that could be used to supply and dispell air through a chosen part of unprotected and non oxygenated segment of space. The Doctor's Tardis had the ability to create an air corridor, and did so for River Song's escape of the Byzantium ship for her to reach the TARDIS safely. (DW: The Time of Angels).
