Rescue breathing (mouth-to-mouth) and chest compressions are used in cardiopulmonary resuscitation (CPR) to temporarily pump enough blood to the brain until specialized treatment is available.
In CPR, chest compressions should come first. Even if you are unable to perform mouth-to-mouth rescue breathing, chest compressions by themselves may still be life-saving. Limit breaks in chest compressions as much as possible until aid arrives.
Breathe for one second into the victim's mouth. Track the rise of the chest.
If the victim's chest lifts, inhale again into their mouth.
If the victim's chest doesn't lift, tilt their head back and bring their chin back down. Then exhale again into the victim's mouth.
