What should you do if the chest doesn't rise and fall when you give the first rescue breath?

• Immediately shift to abdominal thrusts and perform thrusts
• Reposition the victim's head, then use the head tilt chin lift maneuver again to open the airway and give the 2nd rescue breath.
• Sit the guest upright and administer back blows until the object is dislodged
