The Navy Experimental Diving Unit NEDU evaluated a prototype Primary Electronics Assembly PEA for the NK 16 Underwater Breathing Apparatus UBA which can reduce the in-water decompression obligation by increasing the operating partial pressure of oxygen PO2 level from O.75 atmospheres absolute ATA to 1.3 ATA. Upon descent to a depth of 33 plus or minus 2.4 feet sea water fsw 1O plus or minus O.73 meters of seawater msw the electronics switch from O.75 to 1.3 ATA PO2 set point control that is maintained until the diver ascends above 12 plus or minus 2 fsw 4 plus or minus O.6O msw, where the electronics switch back to the 0.75 ATA PO2set point mode.
