CBS Healthwatch stated that Cynthia Crawford had some mighty shocks to get her heart going at Oschner Clinic in New Orleans after she collapsed.
She was placed in an "inlfatable cocoon that sprayed her body with hundreds of cold icy jets of water: plunging her into hyperthermia...
Her cardiologist Dr. Paul McMillan stated that it was "like jumping into the North Sea.."
W hen Crawford woke up a few days later it was without the main damage that she would ahve had .For years doctors have used these cooling techniques to limit damage from brain and spinal cord injuries and even to help with premature babies..
New Yord and some other cities like Sacramento are requiring ambulances to take these patients where they can have cooling for their recovery..what do you think about this?
