Without human breath underwater, anyone can survive for much longer using an oxygen particle recently invented. There are many other uses as well, including medical procedures or emergency situations. It works by being injected into the blood and storing oxygen allowing the person to stop breathing for up to 30 minutes. The oxygen particle is 2-4 micrometers, deformable, made of lipids to hold the oxygen and stores 3-4 times more oxygen then red blood cells. It is especially suited for water related activities.
