Orlando, Fla—Time is a precious commodity
for a person experiencing cardiac arrest.
In the majority of cases, cardiac arrest is caused by ventricular fibrillation,
and survivability drops up to 10% for every minute that elapses until a normal
heart rhythm is reestablished—which usually requires defibrillation.
With the overall survival rate in the United States for out-of-hospital
cardiac arrest at around 5%, emergency medicine researchers are hopeful that
automated external defibrillators (AEDs) can improve outcomes for a condition
claiming hundreds of lives daily. The thinking behind AEDs as a means of boosting
survival is that they can be placed throughout the community and be used quickly
by lay persons.
