Apparatus for use during open system diving to support underwater human respiration. In accordance with various embodiments, an air supply provides a supply of air along a supply conduit. A regulator is adapted for engagement with a diver's mouth to receive air from the supply during an inhale cycle and to direct a mixture of water and exhaust air away from the diver along an exhaust conduit during an exhale cycle. An air/water separator separates the exhaust air from the water in said mixture and directs the separated exhaust air through an exhaust air port. In some embodiments, a one-way stop valve is provided within the air/water separator to prevent back flow. In further embodiments, a bubble diffuser emits the exhaust air as a fine mist of bubbles into the surrounding water.
An open system breathing apparatus to support underwater human respiration, comprising:
An apparatus comprising a bubble diffuser adapted to receive exhaust air along a conduit from a human diver engaged in open system self contained underwater breathing apparatus (SCUBA) diving, the bubble diffuser comprising a housing with a mounting feature adapted for mounting to an air tank secured to the diver, the housing adapted to receive a volume of said exhaust air and to transfer the same through a plurality of apertures extending through the housing as an array of bubbles into the surrounding water.
An apparatus, comprising:
