Both men met in Paris in December and adapted Gagnan's regulator to a diving cylinder. After fixing some technical problems they patented the first modern demand regulator in He felt then what is now called a nitrogen narcosis. During the s and all through World War II , British , Japanese , Italians and Germans developed and extensively used oxygen rebreathers in order to fit out the first frogmen.
