Thank you for all the replys.
The way it works here in Monmouth, NJ. Is that the BLS squad are volunteer backed up by ALS (Monoc) out of the hospitals.
I did a follow up to find out what happend in this case, so far what I know is that the Internal defib., had shocked the PT 3 times before BLS got there, and once while BLS was there, they requested an ALS assist, the medics then transported the pt to the ER where the internal defib shocked once more. It turns out that the defib was malfunctioning, but I dont know yet exactly what happend in the ER in the way of treatment.
It was interesting that the medics transported, because usually when BLS is on scene and they request an ALS assist, a medic then rides in the BLS rig to the hospital. I guess maybe the medics had special non portable equipment in thier rig that they wanted to use.
