Science: Constant Upgrades

Re-evaluation of methodology is one of those things that helps determine whether you're looking at something that has scientists involved or not. If a discovery is made that improves a procedure in a noteable way, it will be adopted, even as the new method is examined for possible flaws or inefficiencies.

And so it is with CPR. The new recommendations are for 30 chest compressions for every 2 breaths instead of the 15/2 ratio currently used. (Note that this is for applying CPR on your own: increase the breath frequency if there is someone there to help you.) There is still a question as to whether cardiopulmonary resuscitation or an automated external defibrillator is a better choice (if one is available). An AED was recently used when Jiri Fischer of the Detroit Red Wings had a seizure with cardiac arrest on the bench during a game against Nashville, and it's low price (about $1500) has many people wondering if they shouldn't be part of every medical supply room in stadiums across North America. They are only if people are trained with them and present to help, but the same is true of CPR.

This is the second major procedural change I can remember since first learning CPR: the "chest thump" was found to be far less effective than compressions, even if the compressions were applied slightly wrong.

Back to class for me, I guess!

I recently published an article on AEDs – here is a quote from it, in case you are interested:

Statistics give us more and more pieces of information that are bound to worry us, to make us react and change something if we can. More and more people and in earlier and earlier stages of their life die of a heart disease. Statistics, only in the US, are extremely alarming:
- Every 30 seconds someone dies because of a heart disease;
- More than 2.500 Americans die daily because of heart diseases;
- Every 20 seconds there is a person dying from a heart attack;
- Each year 6 million people are hospitalized because of a heart disease;
- The number 1 killer is a heart disease.
Although AEDs are not a universal panacea for all heart diseases, nothing else can compete to its major feature, that of actually re-starting the heart after it has been stopped by a sudden cardiac arrest. Under these circumstances is it necessary to ask you why anyone in this world, any family, in any home would hope for having such a device in their first aid locker?

If you feel this helps, please drop by my website for additional information, such as Public Access Defibrillation PAD or additional resources on AED manufacturers such as Philips defibrillators, Zoll AEDs or Cardiac Science AEDs.
