Thanks for your post, Marblehead.

I should have explained ... they have the manikins they need for CPR certification. (All the EMT's are CPR certified.) That was not part of this practice session.)

The reason this "Flat Stanley" is used for AED training with this machine is because it completes the circuit for the training modules. There are 6 different scenarios that require the operator to respond appropriately in order for the shock to be delivered. The CPR simulation is so the operators see that 2 minutes of CPR between evaluations for the need for a shock feels like a long time. (If the first shock doesn't work)
