OCO / Scuba-diving self-rescue system

OCO is a self-saving system to protect divers from accidents under the sea. Many scuba divers get Nitrogen Narcosis caused by high-pressure under the sea. They become unconscious or get in a coma. They will get drowned in the seawater.OCO uses carbon dioxide which is produced by divers themselves to charge the life jacket to bring the unconscious divers to the sea-surface.
