Abstract
The outlets of an oxygen liberating canister and a carbon dioxide absorbing canister are connected with a breathing bag that has an outlet connected to an inhalation tube. An exhalation tube is connected with the canister inlets. A valve system controls the proportion of exhaled air flowing through each canister, from 100% to zero, the system being actuated by the breathing bag as the bag is inflated and deflated.
