If a person has a completely blocked airway (unable to speak, breathe, or cough) and is conscious:

• Tell someone to call 911.
• Stand behind the victim and wrap your arms around him. Make a fist with one hand and place it thumb side against the victim’s abdomen (above navel and well below lower tip of breastbone).
• Holding your fist with your other hand and keeping your elbows out, press fist into victim’s abdomen with a quick upward thrust.
• Repeat as necessary.
