It is proven that the chances of successful defibrillation decline at the rate of 7-10% per minute of delay. And here is precisely where AEDs - automated external defibrillators - come into play. These devices correct the abnormal heart rhythm by providing shock waves as required. The importance of AED, however, is not backed up with public understanding. The public does not take AED very seriously, and that is another point of concern. The six articles reviewed here are full of accurate, recent and verified data that give us a deep insight into the use of automated external defibrillators and of course, the alarming decline in first aid skills in laypersons.
The article is a well researched survey that studies the concept of PAD - Public Access Defibrillation - and how it is highly significant in public life. Out-of-hospital cardiac arrests are naturally much higher than in-hospital attacks, and clearly far more dangerous. There are no paramedics, no doctors - just ordinary people and laymen all around. So, the concept of PAD is clearly a life saving one, and this has been well talked about in the article.
The study design and choice of location is immaculate. The area of survey was Seattle and the surrounding King County, Washington.
