Part of the life support equipment that functions either as: -
Part of a z-suit. - With a respirator mask to allow the wearer
to breathe low pressure atmospheres such as Old Mars and Ephesus
III or when the atmosphere aboard a spacecraft has been
compromised by smoke. A rebreather is a breathing set that
provides a breathing gas containing oxygen and recycles exhaled
gas. As a person breathes, the body consumes oxygen and makes
carbon dioxide. A person with an open-circuit breathing set
typically only uses about a quarter of the oxygen in the air
that is breathed in. The rest is breathed out along with
nitrogen and carbon dioxide. With a rebreather, the exhaled gas
is not discharged as waste: - The oxygen is recovered for re-use
by the recycler. - The carbon dioxide is expelled. - Oxygen is
added to replace what was consumed. If the local atmosphere is
thin but breathable, a compressor and filter can be used to
supply oxygen. - A rebreather is powered by the movement of the
wearer's limbs. - A rebreather and
