text: The semi-closed rebreather systems developed by Drägerwerk in the early 20th century as a scuba gas supply for helmet divers, using oxygen or nitrox, and the US Navy Mark V Heliox helmet developed in the 1930s for deep diving, circulated the breathing gas through the helmet and scrubber by using an injector system where the added gas entrained the loop gas and produced a stream of processed gas past the diver inside the helmet, which eliminated external dead space and equipment work of breathing but was not suitable for high breathing rates.
