before giving breaths to the adult, you should open their airway using the head-tilt/chin-lift technique to which position?

Before giving breaths to an adult, you should open their airway using the head-tilt, chin-lift maneuver. This involves placing one hand on the person's forehead and gently tilting their head back while using the other hand to lift the chin forward. This technique moves the tongue away from the back of the throat, preventing airway obstruction and making it easier to deliver rescue breaths effectively. This method is the standard and safest way to open the airway for providing breaths unless there is a suspected spinal injury, in which case alternative methods should be used. After opening the airway, you pinch the nose shut, make a seal over the person's mouth, and give rescue breaths watching for chest rise to confirm airway patency.
