ABSTRACT:
A mixed gas breathing apparatus reversibly switchable between open circuit and closed circuit systems. Three embodiments show three different levels of redundancy: nonredundant, bi-linear redundant and fully redundant. The counterlung minimizes the static lung loading and thus decreases breathing resistance. Manual control system is readily accessible and allows control of addition of the breathing gases.
