As someone who is an aspiring pilot and knows how air pressure works... I have to say that only works in water. Gas has way different aspects to it. You cant crush someone with particles that freely separated without literally turning it from a gas to a liquid and then potentially into a solid. So unless you're going to be dropping a ton of solid hydrogen/nitrogen/Carbon Dioxide I couldn't see that working.

Just my two cents.
