Funny coincidence that two days ago I rewatched James Cameron's 1989 movie The Abyss, in which perflourocarbon breathing features as a major plot device. Great movie!
And I had no idea that the scene where they force a rat to breathe perfluorocarbons was actually real and not just some really good special effects.
The top media mention is "UFO". The series had a wonderful sense of style, especially characters' uniforms and clothing. It's worth a look-see.
