When should the head tilt-chin lift method be used for rescue breaths in adults?

The head tilt-chin lift method is used for providing rescue breaths to an adult when head or neck injury is not suspected because this technique helps to open the airway effectively. In an unconscious individual, this method allows the rescuer to lift the chin while slightly tilting the head back, which opens the airway by preventing the tongue from blocking it.

In cases where there is a suspected head or neck injury, this technique could potentially worsen the injury by causing misalignment of the vertebrae, leading to further damage. Therefore, it’s crucial to assess the presence of any such injuries before deciding to use the head tilt-chin lift method.

Using this approach ensures that the airway remains clear for ventilations, facilitating proper rescue breaths and aiding in the resuscitation effort.
