Some of the ER's here in Belgium are already working with this device called "LUCAS" over here, I know at least one ambulance in the area that carries the device on board.
The speed and pressure are adjustable so if you split somebody open I think they need to read the manual again, biggest downpoint in pre hospital use is the high amount of compressed air the device uses (around 30litres a minute)
I witnessed one (sucsesfull) reanimation with this device and it is indeed not a pretty sight, on the other side, I rarely perform CPR without cracking ribs myself.
I Believe in it, and after pumping for 40 minutes last night I wished I had one in the car :twisted:
