While the involvement of doctors and paramedics in extrication of trapped patients from cars is limited to medical rather than demolition aspects, it is important for us to understand the general process of extrication.
In particular, the two broad types of extrication are immediate extrication, which is used when patient demise is imminent, and controlled extraction, which is slower but carries less risk. Which of these two techniques the Fire Service use will depend partly on the medical advice they are given after entrapped patients have been assessed.
This paper provides a nice overview of extrication methods.
