Even water will do that, if pressurized somewhat -- the earliest studies
used water. What's harder is finding something that will also dissolve
enough CO2; the early experimental animals died of CO2 poisoning. Both
have to be soluble enough to be carried in and out adequately without
excessive breathing effort (breathing a liquid is much harder work than
breathing a gas, and exhaustion was a contributing factor in the animals'
