January 23, 2007 – Andy Nelson, 58, of Longwood, Florida, recently suffered sudden cardiac arrest (SCA) while mowing his lawn. Paramedics tried to resuscitate him on the way to the hospital. Finally, his heart was shocked back to life, but he remained in a coma. To prevent brain damage, Nelson was treated with mild therapeutic hypothermia using high tech pads filled with cold water. Nelson’s body temperature was lowered for 24 hours, allowing his brain to recuperate slowly. According to a report in the Centre Daily Times (, Nelson and his wife are convinced that cooling made all the difference in his recovery and quality of life.

Mild therapeutic hypothermia is being used more frequently for certain patients. The American Heart Association in 2003 and again in 2005 issued guidelines recommending cooling comatose survivors of cardiac arrest caused by certain irregular heart rhythms known as ventricular tachycardia (VT) and ventricular fibrillation (VF).
