Under what condition should lifeguards immediately use a backboard?

Using a backboard is crucial in scenarios where there is a suspected spinal injury. This is because the backboard provides the necessary support to maintain the position of the spine, preventing further injury while the patron is being rescued. Spinal injuries can lead to paralysis or other severe complications if not managed correctly; thus, lifeguards are trained to utilize a backboard promptly in such cases to ensure the safety of the individual.

In situations that involve unconsciousness or general distress, other rescue techniques may be more appropriate without the immediate use of a backboard. An unconscious person might need other precautions, but if spinal injury is suspected, the backboard must be prioritized to stabilize the spine during the rescue. Tired swimmers generally require assistance or flotation devices rather than immobilization, and while they may need help, their condition doesn’t warrant the same urgent need for a backboard as a suspected spinal injury.
