The U.S. Air Force Research Laboratory has produced FISH, an electronic device with numerous working prototypes. Companies are currently being looked at to manufacture and commercialize the product for non-military use. In 2006, a group of airmen participating in pararescue jumper training were tasked with conducting an underwater exercise that required them to hold their breath for over a minute. While it is expected that someone could pass out, this time 41-year-old, Maj. Brian Adrian blacked out and was unable to be revived. This new device is designed to prevent these tragedies by attaching to a swimmer’s mask and notifying instructors when there is a downward trend in blood oxygen saturation.
