Ready for this one ? Any cop, firefighter, bystander, can do a modified jaw thrust if you tell them put your hands here and do this. I don't see why you couldn't roll the patient supine and the person holding stabilization could also to the modified jaw thrust. Truth is while prone, put a long board on his back, roll him and there you go took away an entire step in your care.
This is not even close to complicated. I understand in Canada Paramedic = US EMT right ? because if they are equivalent you didn't belong in the class to begin with.
