Hypoxia is a condition in which the body is deprived of adequate oxygen supply.
History
Dr. Rodney McKay preferred hypoxia to explosive decompression, when he was trapped in an sinking gateship and had to divert power to the life support. (SGA: "Thirty-Eight Minutes", "Grace Under Pressure")
The crew of the Destiny began showing signs of hypoxia before they fixed the ship's CO2 scrubbers. (SGU: "Air, Part 3").
After Young vented the atmosphere in a room, Telford felt a strong hypoxia and began to asphyxiate. (SGU: "Subversion", "Incursion, Part 1")
