An air or gas embolism can happen when a scuba diver surfaces too quickly from any depth. This can cause air to escape into the blood vessels from the lungs (pulmonary barotrauma) or bubbles of nitrogen to form in the blood vessels (decompression illness, or the bends). An embolism can develop in an artery or vein. When an air bubble travels along an artery, it moves through a system of blood vessels that gradually become narrower. At some point, the bubble may block a small artery and cut off the blood supply to a particular area of the body.
