Abstract
A breathing system is described for underwater diving system which is particularly useful in emergency, 'bailout' situations where the diver's external support is terminated. The invention is particularly characterized by a gas recirculation and purification system which is entirely contained within the helmet and which functions to purify and recirculate exhaled gas within the helmet and to preserve heat generated by the reaction whereby CO.sub.2 is purged from exhaled gas. The invention, further, conserves human respiratory heat by minimizing breathing gas exposure to cold surfaces.
