AEDs save lives
A couple of weeks ago I wrote about the difference that CPR can make to survival rates. This week I’d like to turn our attention to Automated External Defibrillators (AED). A paper written by the Resuscitation Council (UK) in June 2014 showed the positive effect that immediate access to an AED can make and this has been confirmed by a Danish study in June 2015 which was presented at this year’s Euroanaesthesia.
The Resuscitation Council analysed 3500 cardiac arrests, they looked at the use of defibrillators by first responders and via public access. The results showed that where defibrillators had been used prior to first responders or the ambulance arriving the chances of survival had increased to 40%. A study published in June 2015 has confirmed this as well. This study was carried out in Denmark, they found that where an AED was used the survival rate was 50% compared to 19% if no AED was used. Where the person had suffered a shockable rhythm the survival was 64% with an AED and 47% without.
These papers show that the use of an AED is a lifesaver; but the Danish study found that they are not deployed often enough. This can be due to call-handlers not knowing where the nearest AED is located or members of the public not being confident enough to use it.
It is not necessary to have had training to use an AED as they are designed to be used by someone who has not been trained. However, I predominantly train health professionals and it is advisable that they have received training. The AEDs analyse the heart rhythm and determine if it is ‘shockable’ then and only then will it charge and allow the user to deliver a shock. You can see a demonstration in the interactive video Lifesaver.
I encourage my practices to register their AED with the local ambulance service so that they know they have one on the premises and to put the standard sign in their window so passers-by will know they have one on-site.
If you would like help to purchase an AED or to arrange training please contact me.
