Dead space 2 helmet1/21/2024 ![]() The famous series of Kirby Morgan helmets, arguably the most popular in the world, is an example of such modern helmets.įull face masks are used when light weight and agility is required, as in public service diving, cold water diving, or in Special Forces operations. In more modern helmets, the dead space has been reduced by having the diver wear an oral-nasal mask inside the diving helmet, and giving the diver gas only on inhalation using a demand regulator like that used in scuba diving. A flow of up to six cubic feet of gas per minute is sometimes needed to mix and remove the diver’s exhaled breath from a diving helmet like the MK 12. The only way to flush out the exhaled CO2 is by flowing a great deal of fresh gas through that helmet. When we exhale through any breathing device, hose, tube, or one-way valve we expect that exhaled breath to be removed completely, not hanging around to be re-inhaled with the next breath.īut a diving helmet inevitably has a large dead space. In ventilation terms, dead space is a gas volume that impedes the transfer of carbon dioxide (CO2) from a diver or snorkeler’s breath. However, they shared a common problem: Dead Space. Historically, the U.S Navy used the venerable MK 5 diving helmet and the MK 12 diving helmet, which although they had no sensor suites, at least allowed divers to work at fairly great depths without drowning. (I’m not sure where his eyes are, but perhaps in the 26th century a multi-frequency sensor suite makes a simple pair of eyes redundant.) And that is DEAD SPACE in underwater breathing equipment.Ĭlarke has proven to be equally at home underwater and in space due to his interesting cyan-lighted helmet. ![]() ![]() Isaac Clarke and his Dead Space world make a great segue to introduce another matter of personal survival. ![]() The main protagonist of the Dead Space Series was Isaac Clarke. If I was a game player I think I would be an Isaac fan since he was one of those rare Clarke’s known as a “corpse-slaying badass.” If in some unforeseen future my survival depended on being such a slayer, I’d want to be badass about it too, just like Isaac. Sadly, the company that designed the horrifically beautiful game, Visceral Games, is no more. Dead Space is a defunct, or shall we simply say “dead,” survival horror game that enthralled computer game players from 2008 to at least 2013. ![]()
