Nothing ever officially indicates whether or not the masks are necessary to their survival. If the masks do help then we also know they can go without them for some time and this guy was really close to his ship. The mouth piece used in Predator 2 could just as likely be medicinal given his injuries, like it's some kind of morphine mask.
