Abstract

A method and system for supplying a person with breathable fluid in an irrespirable atmosphere. A package which is attached to a person holds a container having a valve which is activated upon removal of a protective cover. The valve allows a breathable fluid to flow at a variable rate to a supply conduit. The supply conduit is connected to a reservoir. An inhalation check valve connects the supply conduit to the person. Upon inhalation, the check valve will open and allow breathable fluid to flow from the supply conduit. Upon exhalation, the inhalation check valve closes and an exhalation check valve opens to permit the breathed air to flow through a filter where carbon dioxide is removed before returning to be mixed with breathable fluid in the supply conduit.
