What is the first step in the pre-crash sequence during a crash procedure?

The first step in the pre-crash sequence during a crash procedure is to lay the patient flat. This action is critical because it helps to stabilize the patient and minimizes potential movement or injury during the crash. By placing the patient flat, the flight paramedic can ensure that the patient's airway is kept clear and reduces the risk of spinal injuries. This position also aids in the distribution of the forces during a crash, potentially protecting vital organs.

Securing the seatbelt is another important safety measure, but it follows the immediate need to lay the patient flat, as this sets the foundation for further safety protocols. Assume crash position, which involves bracing oneself for impact, is also vital, but laying the patient flat takes precedence to ensure their safety and stability first. Turning off the oxygen is not typically a pre-crash action that addresses the immediate welfare of the patient in the same manner as laying them flat does.
