What is the primary purpose of using a rescue tube during a spinal injury rescue?

The primary purpose of using a rescue tube during a spinal injury rescue is to provide buoyancy and support. When a victim has a suspected spinal injury, it is crucial to minimize movement to prevent further injury. The rescue tube helps keep the victim afloat without requiring excessive movement, allowing for safe and stable support while waiting for emergency services or conducting necessary care. By using the tube, the rescuer can maintain the victim's position in the water, alleviating the risk of further aggravation to the spine while ensuring the victim stays above water. This support mechanism is fundamental to managing spinal injury scenarios effectively.
