What equipment is NOT required for the application of Spinal Motion Restriction (SMR)?

In the context of Spinal Motion Restriction (SMR), the focus is on stabilizing and protecting a patient's spine during transportation to prevent further injury. The correct answer indicates that a breathing apparatus is not a necessary piece of equipment for the application of SMR.

SMR primarily requires equipment that aids in immobilizing the patient's spine and preventing movement that could exacerbate any potential spinal injuries. Essential tools like a long plastic spine board provide a rigid surface for transportation, while a cervical collar helps to stabilize the neck and limit movement. A lateral head support device also contributes to maintaining the patient's head in a neutral position, further preventing spinal movement.

Since SMR is not directly related to the management of airway or breathing issues, a breathing apparatus is not a requisite for this specific procedure. This clarifies that while airway management is important in emergency care, the focus of SMR is solely on spinal immobilization and protection.
