Well...they're not the panacea you might think.
1, and most important, not all cardiac arrests will respond to a shock, or even to several shocks. Very briefly, there are 4 main heart rhythms we see during cardiac arrest. Only 2 of 4 respond to shocks AT ALL
Go back to my earlier posts....even with an AED on hand, we get back less than 50%. Depending on age and reason for the arrest, sometimes we're down in low double digits.
NOTE: American AEDs will state, shock advised, or shock not advised. (BTW, if there are AEDS in Spain, they're probably talking in Spanish).
2. AEDs In the US are *expensive,* and require regular calibration and servicing. There's a reason why even the most equipped of us out of hospital responders don't invest un personal AEDs.
3. Please remember that there is no one overarching agency that funds Camino maintenance or improvements.
BL. If a group like APoC or the Confraternity of St James were to ask their grant receivers if they wanted an AED, my personal bet is no. But bring the topic up with your local chapter.
