Over the years we have attended and instructed at many auto extrication events around the country. When using the reciprocating saw, we have noticed varying skill levels being demonstrated by students and instructors alike. Most of the time, the saw is used at full speed, while the operator tries to hold on, as the tool throws them back and forth at 3000 strokes per minute (SPM), until there is smoke and sparks and the blade goes dull since the teeth melted off.

The purpose of our previous article was to encourage creative thought about a situation that would normally have a straightforward approach. As the MVA was evaluated, however, it became more apparent that the technology contained in the vehicle could make reaching the patients in the vehicle more complicated. It was deliberately designed as a tough “what if” scenario, with very specific circumstances involving a hybrid vehicle. There are several ways to approach the situation that we will discuss in this solution. Many thanks to the very knowledgeable individuals who responded with their intelligent and practical solutions to the Honda Civic Hybrid under-ride MVA scenario article.

Keeping in mind that hybrid vehicles have 4 tires and a steering wheel just like all the other vehicles on the road today, the major difference is its propulsion system. Take a conventional vehicle, add a traction motor and high voltage battery, and you basically have a hybrid. This is over simplified to be sure, but makes the point that extrication procedures will differ little between hybrid and conventional vehicles in most cases. Consider the diagram below. Note the position of the high voltage battery, orange high voltage wires and inverter/traction motor. Can you remove the roof of this vehicle for patient access without encountering the high voltage system?
