WRONG ON A COUPLE OF FRONTS!!
I don't know how it works up north, but we get text messages from the regional ems when there is a call in our district. This text includes, location, kind of call and the applicable codes.
Some of us have application within the phone where we can indicate that we are responding, and a gps that guides us to the location.
BTW, we also use phones to get in touch with medical control while on scene away from the rig.
Is there some distinct reasoning that is being given for non use of phones?
