Which of the following is NOT a strategy to increase your safety while performing CPR in the back of a moving ambulance?

Bracing your head against the wall or roof while performing CPR in a moving ambulance could compromise your stability and ability to effectively perform the chest compressions and ventilations required during CPR. This approach does not enhance safety and may actually increase the risk of injury to both the responder and the patient due to the instability of the moving environment.

In contrast, securing yourself with a seatbelt is a standard safety practice that protects the provider from being thrown around during sudden movements or turns. Positioning the patient flat on a stable surface allows for effective compressions and helps maintain the patient's airway. Working with a partner can also ensure that one person can focus on providing compressions while the other can handle ventilations and manage the situation more effectively. Each of these strategies fosters a safer environment for conducting CPR in challenging conditions.
