The current study, which involved 125 patients, reports the experiences after the revised protocol was implemented in two Wisconsin counties in a collaboration between the CPR Research Group at the University of Arizona's Sarver Heart Center and the Mercy Health System in Wisconsin.
"We think one of the reasons that CPR as directed by international guidelines has not worked well is because it is designed for two entirely different conditions: cardiac arrest and respiratory arrest," said Dr. Ewy. "What is good for one may not be good for the other. Cardiocerebral Resuscitation is designed for cardiac arrest. Sudden unexpected collapse in an adult is almost always due to cardiac arrest. The new approach is not recommended for respiratory arrest, a much less common situation following, for example, drowning or drug overdose."
As a cause of death, out-of-hospital cardiac arrest is second only to all cancer deaths combined, taking the lives of 490,000 Americans every year. Unlike the impression created by TV shows such as "E.R.", the chance of surviving an out-of-hospital cardiac arrest is usually much less than 10 percent. In spite of periodic updates of standardized international guidelines, survival rates have remained more or less unchanged over the last couple of decades. Survival rates are better only if an automated external defibrillator (AED) is available and is used soon after the cardiac arrest.
