How should you position the victim's head before giving rescue breaths?

Before giving rescue breaths, positioning the victim's head by tilting it back slightly is essential to create an open airway. This slight tilt helps to move the tongue away from the back of the throat, reducing the chance of airway obstruction due to the tongue's natural position in an unconscious person. Properly aligning the airway is critical because it facilitates more effective ventilation and ensures that the breaths you give can reach the lungs without interference.

Additionally, this head tilt, combined with a lift of the chin, is the recommended technique in CPR to optimize the breathing process and improve the chances of successful ventilation. Proper positioning is a fundamental skill to enhance the effectiveness of rescue breathing procedures during CPR, which is vital in helping to restore effective breathing and circulation in an individual who has become unresponsive.
