Where should a rescuer position themselves when performing rescue breathing in the water?

When performing rescue breathing in the water, positioning behind the person's head is critical for several reasons. This position allows the rescuer to maintain control over the airway while delivering breaths effectively. By being behind the individual's head, the rescuer can securely support the victim's neck and keep their head tilted back, which opens the airway and reduces the risk of water entering the lungs during the rescue breaths.

Additionally, this positioning provides a more stable foundation for the rescuer to perform the necessary technique of sealing the mouth around the victim’s mouth or using a rescue mask if available. It also ensures that the rescuer remains in a position of safety, enabling them to react promptly if the victim shows signs of regaining consciousness or if the situation changes rapidly.

In contrast, other positions, such as in front of the person or beside them, may hinder the proper alignment of the airway and can complicate the breathing process. Being underwater near the person's feet would also be ineffective, as it would prevent a clear airway and make it difficult to perform rescue breathing safely.
