When should a lifeguard use the head-tilt, chin-lift maneuver?

The head-tilt, chin-lift maneuver is an essential technique used by lifeguards to ensure an open airway when delivering rescue breaths or performing CPR. By tilting the head back and lifting the chin, the lifeguard helps to move the tongue away from the back of the throat, which can obstruct breathing. This maneuver is crucial in situations where the victim is unconscious or unable to breathe adequately on their own.

In the context of resuscitation efforts, having a clear airway is a primary concern, as it directly affects the effectiveness of the breaths being delivered. This action is not typically associated with assessing injuries, evacuating people from the water, or teaching safety classes, as those scenarios require different approaches and techniques focused on evaluation, safety, and education rather than immediate life-saving maneuvers.
