What is a rescue tube and how is it used?

A rescue tube is a buoyant flotation device specifically designed for lifesaving and rescue situations. Its primary purpose is to provide support to a distressed swimmer or individual in the water, enabling the rescuer to assist them more effectively. The rescue tube is typically made of durable, lightweight materials that keep it afloat, allowing a lifeguard or rescuer to throw it to someone in need of help or to use it to stabilize the person while bringing them back to safety.

This device can also be used as a means of tethering the rescuer to the victim, which helps in maintaining control and ensuring both individuals are safe during the rescue operation. The buoyancy of the tube alleviates the physical strain on the rescuer, making it easier to transport someone who may be panicking or unable to swim.

In contrast, other options like signaling devices, first aid kits, or swimsuits serve very different functions and do not directly relate to the actions taken during a water rescue scenario.
