What is the primary objective of using a rescue tube during a water rescue?

The primary objective of using a rescue tube during a water rescue is to provide flotation support and improve rescue efficiency. Rescue tubes are designed to assist both the rescuer and the victim; they keep the victim afloat, preventing drowning and reducing the likelihood of panic. By allowing the rescuer to maintain buoyancy and stability in the water, the use of a rescue tube enhances the effectiveness of the rescue operation. This provides the rescuer with the ability to maneuver more effectively while also offering the person in distress a means of remaining above the water's surface until they can be brought to safety. Thus, the rescue tube plays a crucial role in both stabilization and support during water rescues, ultimately improving the chances of a successful outcome.
