Injected Oxygen Foam Saves Lives
We all need to breathe as swimmers are especially aware. Underwater swimmers can train themselves to disregard the urgent desire to oxygenate their blood and stay underwater for several minutes at a time.
See the Human Planet Video.
The New Zealand freediver David Mullins set a world record by swimming 218m underwater without taking a breath.
In the end we all have to come up for air, but a new innovation: “oxygen foam” developed by Dr. John Kheir, a researcher and emergency room physician at Children’s Hospital Boston could prolong the body’s ability to withstand non-working lungs by delivering oxygen straight into the blood.
This new treatment could well have applications outside the operating theater. It could be used for emergency oxygenation at swimming pools and possibly enable swimmers to stay underwater for a very long time.
