ABSTRACT:
A self contained apparatus for indefinite respiration in non-air environments is provided and consists of a vest pack having a front section, a pair of flexible shoulder bars and a back section which is worn by a diver. A mechanism is for securing the front section and the back section of the vest pack about the waist of the diver. Water is stored in the back section of the vest pack. An air hose extends from the top of the flexible shoulder bars of the vest pack. A mouthpiece is connected to the air hose and another mechanism is within the vest pack, for electrolyzing the water in the back section so as to release the oxygen and allow the diver to breath the oxygen through the mouthpiece.
