I would encourage you to take an EMT or First Responder course before you attempt to provide care in the field. Depending on which state you are in you may not be wise to do anything outside of your hospital. Things are different on the side of the road. Although I would agree that your care is better than none, you may be opening yourself up to even more liability than just calling 911. The worst thing to happen in the field is for a hospital nurse or doctor to show up at the scene of an accident. Unless they are trained in prehospital care they are generally in the way. As for the DR. on the scene, they usually shout out orders until they realize that when you are knee deep in loon sh*t (which may happen here in MN) there aren't things like good lighting and temp controlled rooms. Leave prehospital stuff to those trained in prehospital care. I can say that as an EMT and a RN student. I as an EMT wouldn't come into an ER and start providing care if I wasn't trained. PS- I know there are issues between EMT's and Nurses so please dont kill me.
