The following is an excert from an article found at http://www.independent.co.uk/news.
Gardell Martin had no pulse and was not breathing when he was discovered by neighbours after falling into a freezing creek in Union County, Pennsylvania.
The 22-month-old boy had gone outside to play with two of his brother on 11 March when he fell into the stream that runs through the family’s garden in the town of Mifflinburg, and was swept away by the strong current.
He was found by a neighbour nearly a quarter of a mile away, caught up in a tree branch.
The ambulance crew who arrived minutes later found no pulse and instigated CPR which continued, unbroken, for 101 minutes in the ambulance, at a local hospital, on a medical helicopter and, finally, in the pediatric wing of the Geisinger Medical Center in Danville.
Gardell was suffering from profound hypothermia when he arrived at Geisinger which apparently worked to his advantage, dramatically slowing his metabolism and giving his organs “some degree of protection from cardiac arrest” according to Dr Frank Maffei, director of pediatric intensive care at the hospital.
Knowing this, he ordered CPR to continue whilst the team slowly warmed the body and, when Gardell reached around 28 degrees, a pulse was detected and he regained consciousness hours later.
His brain also showed no signs that it had been affected by the cardiac arrest.
When a person’s heart stops, it is known as being in ‘cardiac arrest’. Cardiopulmonary resuscitation (CPR) is a combination of techniques, including chest compressions, designed to pump the heart to get blood circulating and deliver oxygen to the brain until definitive treatment can stimulate the heart to start working again.
