A new study, reported in the Journal of the American College of Cardiology, concludes that PAD (Public Access Defibrillation) doubles the chances of survival.
The results (viewable on the abstract on their website here) show…
“Of 13,769 out-of-hospital cardiac arrests, 4,403 (32.0%) received
bystander cardiopulmonary resuscitation but had no AED applied
before EMS arrival, and 289 (2.1%) had an AED applied before
EMS arrival. The AED was applied by health care workers (32%),
lay volunteers (35%), police (26%), or unknown (7%). Overall
survival to hospital discharge was 7%. Survival was 9% (382
of 4,403) with bystander cardiopulmonary resuscitation but no
AED, 24% (69 of 289) with AED application, and 38% (64 of 170)
with AED shock delivered. In multivariable analyses adjusting
for: 1) age and sex; 2) bystander cardiopulmonary resuscitation
performed; 3) location of arrest (public or private); 4) EMS
response interval; 5) arrest witnessed; 6) initial shockable
or not shockable rhythm; and 7) study site, AED application
was associated with greater likelihood of survival (odds ratio:
1.75; 95% confidence interval: 1.23 to 2.50; p < 0.002).
Extrapolating this greater survival from the ROC EMS population
base (21 million) to the population of the U.S. and Canada (330
million), AED application by bystanders seems to save 474 lives/year.
Conclusions: Application of an AED in communities is associated with nearly
a doubling of survival after out-of-hospital cardiac arrest.
These results reinforce the importance of strategically expanding
community-based AED programs.”
With the cost of AEDs dropping, there doesn’t seem to be any excuse left for not having one available in all public locations (airports, churches, malls, gyms, schools, etc…)
Today’s AEDs walk you through (there’s literally a voice that talks to you) what to do and how to do it. They tell you if there’s a problem and whether or not defibrillation is necessary (they will not allow defibrillation if the heart is not in fibrillation so you can’t accidentally shock someone) and some even let you know if you compressions aren’t strong or deep enough.
