How To Breathe With No Air While it’s commonly believed that air in the blood stream can cause death by embolism a new way of preventing suffocation actually involves injecting oxygen straight into the blood stream. The crucial difference is that the oxygen comes in the form of lipid based single layer microparticles that act as microscopic bubbles (pictured) and was designed by researchers at the Boston Children’s Hospital. The technique itself can buy an extra half an hour before oxygen deprivation sets in, considering brain damage begins after 4 minutes of suffocation this can be the difference between life and death. Unfortunately due to the lipid (basically just fat/oil) structure of these microparticles this process can’t be prolonged as it would create further problems. Also interestingly the creation of these particles uses sound-waves to mix the lipid and oxygen together forming a liquid that in the end is 70% oxygen and mixes effectively into the blood. It also carries oxygen about 3-4 times better than our own blood. Image Courtesy of Children’s Hospital Boston
