Status
Determining the method of extrication can be a very difficult decision. The following four critical factors must be addressed when making this decision.
1) Time necessary to complete the extrication
2) Effects the extrication will have on the patient
3) Effect extrication will have on rescuers
4) Effects (damage) the extrication will have on the equipment involved.
Extrication can be accomplished in three basic ways:
Manipulative extrication, disassembling the machine, or forcing the machine.
This method is the least desirable because it is the least predictable and may cause extensive damage to the expensive machinery and may prove risky to the patient.
Forcing the machine
