I also serve as a Medical First Responder in the community where I live.
Last week I was toned out to respond to a local church where a person had passed out.
By the time I got there, two people in attendance at the church had determined non-responsiveness, called 911, determined non-normal breathing, begun CPR, retrieved the AED, applied it, and had a living, breathing Cardiac Arrest Survivor on their hands. The victim was transported and now has a pacemaker.
That, my friends, is how we solve the problem of too many dying form SCA's: Available AEDs and people who know how to recognize a Sudden Cardiac Arrest when it happens and what to do!
It's nice not being needed!
