Oxygen rebreathers are severely depth-constrained due to oxygen toxicity chance, which improves with depth, as well as obtainable devices for blended gas rebreathers had been pretty bulky, created for use with diving helmets and sometimes relied on a relentless move gasoline source for driving recirculation.[twelve]
