Knowing what to do when someone is choking is a preparedness skill that lets you clear a blocked airway in the minutes before help arrives. Choking happens when food or a small object lodges in the throat and stops air from reaching the lungs. With the right steps, you can turn a frightening moment at the table into a short, handled one.
You do not need a medical background to learn this. Most choking happens at home, during ordinary meals, with family close by. That means the first responder is usually whoever sits nearest. Emergency crews often need several minutes to arrive. The steps below teach you how to fill that gap with calm, practiced hands.
Start by reading the steps once tonight. Then walk through the hand positions with a family member this weekend. Practice the motions gently, without real force, so your hands already know where to go if you ever need them.
What to Do When Someone Is Choking Starts With the Signs
Picture a Sunday dinner. Someone across the table laughs mid-bite, takes a sharp breath, and suddenly goes quiet. Every head turns. The first step in what to do when someone is choking is deciding which kind of choking you are seeing. Reading the signs correctly tells you whether to coach or to act. Next, you will learn exactly how to act when the airway is fully blocked.
Mild Choking: The Cough Is Working
In mild or partial choking, the person can cough forcefully, speak, or breathe. Air is still moving past the blockage. A strong cough is the best tool the body has for clearing it.
Encourage the person to keep coughing. Stay right beside them and keep your voice calm. Keep your hands ready but off their back while the cough is strong. Back blows or thrusts can interrupt a cough that is already doing the job. Watch closely, because the situation can change. If the cough grows weak or stops, treat it as severe choking and act at once.
Severe Choking: The Airway Is Blocked
Severe choking means little or no air can pass. Look for these signs:
- Hands at the throat. Clutching the throat with one or both hands is the universal choking sign.
- No voice. The person cannot speak, cry, or cough effectively.
- Weak cough. Any cough is faint, silent, or clearly not moving air.
- Strange breathing sounds. You hear high-pitched squeaks, or no sound at all, when they try to breathe.
- Panic. The person looks frightened, stands up suddenly, or reaches out for help.
- Color change. Lips, skin, or nail beds turn blue or gray as oxygen drops.
Ask clearly, 'Are you choking?' If the person nods but cannot speak, act now. Point to one specific person and tell them to call 911 right away. If you are alone with the person, dial 911, put the phone on speaker, and start helping while it rings.
How to Give Back Blows and Abdominal Thrusts
Back blows and abdominal thrusts push air up from the lungs with enough force to pop a stuck object loose. These steps work for a conscious adult or a child over one year old with a severe blockage. Abdominal thrusts are also called the Heimlich maneuver. After the steps, you will learn how to adjust for special situations, and then what to do if the person passes out.
- Ask permission. Say, 'I know first aid. Can I help?' A nod is enough consent, and your calm voice helps the person stay still.
- Get 911 on the way. Have someone else call so your hands stay free for the rescue.
- Get into position for back blows. Stand slightly behind and to the side of the person. Place one hand across their chest for support. Lean them forward so the object moves toward the mouth.
- Give up to 5 back blows. Use the heel of your other hand. Strike firmly between the shoulder blades. Check after each blow to see if the object came out.
- Move behind for abdominal thrusts. Stand directly behind the person and wrap your arms around their waist. For a child, kneel down to their height.
- Place your fist. Make a fist with one hand. Put the thumb side just above the navel and well below the breastbone. Grasp your fist with your other hand.
- Give up to 5 abdominal thrusts. Pull in and up with quick, firm motions. Each thrust acts like a forced cough from below.
- Keep alternating. Repeat 5 back blows and 5 abdominal thrusts. Continue until the object comes out, the person can breathe or cough forcefully, or they become unconscious.
Two Accepted Approaches
You may have learned this a little differently, and that is fine. The American Red Cross teaches the cycle of back blows and abdominal thrusts. The American Heart Association emphasizes abdominal thrusts alone. Both are accepted approaches. Use the one you trained in and repeat it without pausing to second-guess.
Pregnancy and Larger Bodies
If the person is pregnant, or your arms cannot reach around their waist, use chest thrusts instead. Stand behind them and place your fist in the center of the breastbone. Grasp it with your other hand and pull straight back. You keep the same standing position and the same rhythm, so the switch is quick.
If You Are Choking Alone
Call 911 first, even if you cannot speak. An open line lets the dispatcher send help. Then make a fist, place it above your navel, and thrust inward and upward with your other hand. You can also lean over the back of a sturdy chair and press your upper abdomen against it with force.
What to Do If the Person Becomes Unconscious
These steps keep oxygen moving and keep working on the blockage after a person passes out. If back blows and thrusts do not clear the airway, the person may go limp. Your role shifts from thrusts to CPR, and you stay in the rescue until help takes over. After that, you will learn about follow-up care, babies, and prevention.
- Lower the person to the floor. Guide them down gently onto their back. Cradle the head so it does not strike the floor or furniture.
- Confirm help is coming. Make sure 911 has been called. Put the phone on speaker so the dispatcher can coach you through each step. Send someone to get an AED if one is nearby.
- Start chest compressions. Place the heel of one hand in the center of the chest and your other hand on top. Push hard and fast for 30 compressions. Press at least 2 inches deep at a rate of 100 to 120 per minute.
- Look in the mouth. Before giving breaths, open the mouth and look for the object. Remove it only if you can see it and grasp it easily. Keep your fingers out of the throat when you cannot see anything, because blind finger sweeps can push the object deeper.
- Give 2 rescue breaths if trained. Tilt the head back, lift the chin, and breathe into the mouth. If the chest does not rise, reposition the head and go straight back to compressions.
Compressions do double duty. Each push raises pressure inside the chest, which can help force the object out. Check the mouth each time you pause for breaths.
If you have no CPR training, give hands-only CPR. Continuous chest compressions are far better than doing nothing. The dispatcher can count with you and keep your pace steady.
Keep going until the person starts breathing, emergency responders take over, or an AED is ready to use. For the wider set of skills between the call and the ambulance, the Prepper Life guide You Are the First Responder After You Call 911 covers the full picture.
After the Emergency: Special Cases, Follow-Up Care and Prevention
Follow-up care catches hidden injuries, and simple habits lower the odds of a repeat. A successful rescue is a real win. The next steps protect the person afterward and prepare you for the youngest members of your family.
Get a Medical Check
Take anyone who received abdominal thrusts, chest thrusts, or CPR to a doctor. These techniques save lives, and they can also bruise ribs or injure organs inside. Seek care too if the person has a lingering cough, trouble swallowing, or a feeling that something is still stuck. A small piece can remain in the airway even after breathing returns.
Babies Under 1 Year
Infants need a gentler method. Hold the baby face down along your forearm, with the head lower than the chest. Support the jaw with your hand and rest your arm on your thigh. Give 5 firm back blows between the shoulder blades with the heel of your hand. Then turn the baby face up, keeping the head low. Place two fingers on the center of the chest, just below the nipple line, and give 5 chest thrusts. Repeat until the object comes out or help arrives. Use only back blows and chest thrusts on infants. Abdominal thrusts are never used on babies under 1 year.
Choking Risks at the Table
Knowing what to do when someone is choking matters most, and prevention means you need it less often.
- Cut food small. Bite-sized pieces pass through the throat more easily.
- Chew slowly. Thorough chewing turns food soft before it reaches the airway.
- Finish the bite first. Swallow before talking or laughing, since a sharp breath can pull food into the windpipe.
- Limit alcohol. Drinking before and during meals dulls the swallowing reflex.
- Supervise young children. Keep kids seated and watched while they eat.
- Prepare toddler foods with care. Quarter whole grapes, slice hot dogs lengthwise instead of into rounds, and save nuts and hard candy for older children.
The strongest step you can take is a certified first aid and CPR course from the American Red Cross or the American Heart Association. Hands-on practice with an instructor builds the confidence that reading alone cannot.
