NASA once accidentally depressurized a man while testing space suits in a vacuum chamber. He lost consciousness in less than 15 seconds, but fully recovered after depressurization. He reported feeling his saliva boil which is... exciting. https://www.youtube.com/watch?v=KO8L9tKR4CY https://www.youtube.com/watch?v=KO8L9tKR4CY http://www.spacesafetymagazine.com/aerospace-engineering/space-suit-design/early-spacesuit-vacuum-test-wrong/ http://www.spacesafetymagazine.com/aerospace-engineering/spa... During Project Excelsior, Joseph Kittinger's right hand was depressurized at 100,000 feet and swelled up, but he was ultimately unharmed. https://en.wikipedia.org/wiki/Project_Excelsior#Test_jumps https://en.wikipedia.org/wiki/Project_Excelsior#Test_jumps
