Rabbits kept alive by oxygen injections
Posted July 8, 2012on:
Rabbits with blocked windpipes have been kept alive for up to 15 minutes without a single breath, after researchers injected oxygen-filled microparticles into the animals’ blood.
Oxygenating the blood by bypassing the lungs in this way could save the lives of people with impaired breathing or obstructed airways, says John Kheir, a cardiologist at the Children’s Hospital Boston in Massachusetts, who led the team. The results are published today in Science Translational Medicine1.
The technique has the potential to prevent cardiac arrest and brain injury induced by oxygen deprivation, and to avoid cerebral palsy resulting from a compromised fetal blood supply.
