Oxygen was the fifth episode of the tenth series of Doctor Who produced by BBC Wales.
The episode is most notable for showing the risks the Doctor places himself in to save his friends. In this case, saving Bill robs him of his sight, with an attempt to fix it failing, rendering this incarnation of the Doctor blind.
Synopsis

Physics
- The Doctor gives a lecture about space, while the audience was expecting a lecture about crop rotation.
Technology
- The Doctor calls distress calls "[his] theme tune", and emphasises that "You only see the true face of the universe when it's asking for your help."
- Chasm Forge uses artificial gravity.
- The Doctor is happy that the "space doors", as Nardole calls them, are of a classic design. They have pressure seals and hinges. He and Nardole disagree on whether space doors should go "shk shk" or "nnnnn".
- The smartsuits employed at Chasm Forge uses gyros stabilisers, magnetic boots and gloves, and has on-board computech. According to the Doctor, it can run, jump and update one's Facebook. They also have force fields to keep the air in, and oxygen tanks for air supply.
- A magnetic glove on one of the active suits destroys the Doctor's sonic screwdriver, though the sonic also fries the suit.
- The suits' AI have "limited problem solving".
- To send the distress call, the miners boosted a smartsuit through the dish.
- Nardole relates the smartsuits' nav system to "when your satnav doesn't know a new road".
TARDIS
- The Doctor once told Nardole that the TARDIS can't go anywhere without the fluid link K57. However, he reveals this to be untrue.
- The air shell room in the TARDIS can provide oxygen to enough of the space station for them to stroll around.
Units of measurement
- Distance is measured in average breaths, rather than in metres.
Locations
- The Doctor sent Nardole to Birmingham for a packet of crisps.
- Chasm Forge is a mining station in outer space. It has a crew of 40.
Resources
- Chasm Forge is a station for mining copper ore.
Travelling
- The Doctor compares going to outer space to camping, and refers to tents and campsites.
- Bill asks if there are reviews for space locations, like there are online for restaurants.
Businesses
- The smartsuits are made by Ganymede Systems.
- Ganymede provides oxygen for personal use only, charging credits for air, and making breathing into a capitalist endeavour. Unauthorised oxygen is automatically expelled, to protect market value.
Biology
- The Doctor purposely "maxes out" his companions' adrenaline: "Fear keeps you fast. Fast is good."
- Bill wonders what happens if she were to throw up in the space helmet.
- After having been exposed to the vacuum of space, Bill suffers from oxygen deprivation.
People
- As a result of saving Bill from suffocating in space, the Doctor has now become blind. An attempt to return his vision was made, but only the colour in his eyes returned.
- Nardole recognises the smartsuit's interface voice as his ex Velma, and remembers her as a "nice girl, actress. Bit orange, left me for an AI at a call centre."
Culture
- The Doctor mentions, amongst other things the smartsuits can do, updating Facebook.
- Dahh-Ren cannot understand why Bill would experience racism herself.
Literature
- The Doctor says, "Death, where is thy sting?", quoting the First Epistle to the Corinthians in the New Testament.
