Choking is one of the few emergencies where a bystander's quick, correct action often matters more than anything a paramedic can do after arrival. The airway is blocked, oxygen is running out, and the response has to happen in the first minute or two. This guide walks through choking rescue techniques for adults, children, and infants, including what to do if you are the one choking and no one else is nearby. No equipment is required to perform any of these steps, but practicing them hands-on in a certified CPR and First Aid course is the best way to make sure your response is automatic rather than hesitant when it counts.

Step 1: Recognize the Signs of Choking

Choking falls into two categories, and telling them apart determines what you do next. Mild airway obstruction means the person can still move air around the blockage. They may be coughing forcefully, wheezing between coughs, or able to speak a few words. In this case, the airway is still partially open, and a hard, natural cough is often more effective at dislodging the object than anything you could do.

Severe obstruction looks very different. The cough becomes weak or silent, no air moves in or out, and the person cannot speak or cry out. Skin around the lips or fingertips may start to turn bluish (cyanosis) as oxygen levels drop. Many people also display the universal choking sign: one or both hands clutched to the throat. This gesture is widely taught and recognized, so if you see it, take it seriously even if the person hasn't said a word.

The most common mistake bystanders make at this stage is assuming the person is joking, being dramatic, or just having a coughing fit, and waiting to see if it resolves on its own. Choking can look alarming but brief, or it can escalate in seconds. Rather than guessing, ask directly: "Are you choking?" If the person nods or cannot answer, treat it as an emergency and move to the next step immediately. Asking costs you two seconds and removes all doubt.

Step 2: Decide Whether to Intervene

Once you've identified that someone is choking, your next decision is whether to physically intervene or let their own body do the work. If the person is coughing forcefully, speaking, or able to breathe between coughs, do not perform abdominal thrusts. Encourage them to keep coughing, stay close, and watch closely for any change. A strong cough generates more pressure than most rescue maneuvers and is often enough to clear a partial blockage on its own.

The moment that cough weakens, goes silent, or stops producing any sound at all, the situation has shifted to a severe obstruction and you need to act without delay. There is no benefit to waiting longer to "see if it clears up" once air movement has stopped. Begin abdominal thrusts immediately.

At the same time, get emergency services involved. Call 911 yourself if you're alone with the person, using speakerphone so you can keep both hands free to help. If other people are around, point to one person directly and tell them to call 911 while you begin rescue efforts. Do not wait until after you've tried a few thrusts to make the call. Choking can resolve quickly, but it can also require more advanced airway management if your efforts don't work, and EMS needs lead time to arrive. Starting the call and starting the rescue happen in the same moment, not one after the other.

Step 3: Perform Abdominal Thrusts (Heimlich Maneuver) on a Conscious Adult or Child

Abdominal thrusts, commonly known as the Heimlich maneuver, use a sharp upward push under the diaphragm to force trapped air out of the lungs and push the object out of the airway. According to guidelines from organizations such as the American Heart Association and the American Red Cross, the technique for a conscious adult or child (generally over one year old) follows this sequence:

  1. Stand behind the person and wrap both arms around their waist, positioning yourself so you can maintain balance if they suddenly go limp.
  2. Make a fist with one hand and place the thumb side against the person's abdomen, just above the navel and well below the bottom of the ribcage.
  3. Grasp your fist firmly with your other hand.
  4. Deliver quick, sharp thrusts inward and upward, as if trying to lift the person slightly off the ground.
  5. Repeat these thrusts one after another until the object is expelled, the person starts coughing or breathing normally, or the person becomes unresponsive.

For someone who is visibly pregnant or whose size makes it hard to wrap your arms around their abdomen, move your hand position higher, placing your fist against the center of the breastbone instead of the abdomen, and deliver the same upward thrusts as chest thrusts rather than abdominal thrusts. This avoids added pressure on the abdomen while still generating enough force to clear the airway.

If you are shorter than the person choking, or they are seated, adjust your stance and grip as needed but keep the core mechanics the same: fist above the navel, below the ribcage, sharp inward and upward motion. Each thrust should be a distinct, forceful movement rather than a gentle squeeze. Continue without pausing to check for improvement after every single thrust; instead, watch continuously and stop as soon as the airway clears or the person loses consciousness.

Step 4: Modify the Technique for Infants Under One Year

Abdominal thrusts should never be used on infants. Their abdominal organs sit closer to the surface and are more easily injured by the force required to clear an airway obstruction, so current guidelines call for a different combination: back blows paired with chest thrusts.

To perform this technique safely:

  1. Sit or kneel, and position the infant face down along your forearm, supporting their head and jaw with your hand. Their head should be lower than their chest.
  2. Rest your forearm on your thigh for stability, then deliver up to 5 firm back blows between the shoulder blades using the heel of your other hand.
  3. If the object hasn't cleared, turn the infant face up, still supported along your forearm with the head lower than the trunk, and switch your supporting arm to your thigh if needed.
  4. Using two fingers, place them on the center of the infant's breastbone just below the nipple line and deliver up to 5 quick chest thrusts, compressing about 1.5 inches.
  5. Alternate between sets of 5 back blows and 5 chest thrusts, checking the mouth for a visible object after each set, until the object is expelled or the infant becomes unresponsive.

Move deliberately but without delay between back blows and chest thrusts; the entire cycle should flow as one continuous rescue effort. Many parents and childcare providers know the term "Heimlich maneuver" but have never learned this infant-specific version, which is exactly why hands-on practice with a training manikin, offered in courses at Midwest CPR Center, matters so much before you're ever faced with the real thing.

Step 5: Respond If the Person Becomes Unresponsive

If abdominal thrusts, or back blows and chest thrusts for an infant, don't clear the obstruction and the person loses consciousness, lower them carefully to the ground, supporting their head as they go down. At this point the response shifts into CPR, beginning with chest compressions rather than rescue breaths, following current CPR guidance for both adults and infants.

Before attempting to give rescue breaths, open the person's mouth and look inside. If you can see the object, remove it with a finger sweep. Do not perform a blind finger sweep if you cannot see anything, since this can push the object deeper into the airway instead of out. Chest compressions themselves can also help dislodge a foreign object by generating pressure similar to a cough, so don't assume compressions are pointless just because the cause is choking rather than cardiac arrest.

Continue cycles of chest compressions, checking the mouth for the object, and attempting rescue breaths when the airway appears clear, following the same 30:2 ratio used in standard CPR unless you've been trained in a different current protocol. Keep going until the object is expelled and the person starts breathing on their own, EMS personnel arrive and take over, or you are physically unable to continue. If a second trained rescuer is present, switch roles periodically to avoid fatigue, since compression quality drops quickly once you tire. This is one more reason formal CPR training matters: the sequence between checking, compressing, and breathing needs to happen smoothly and without hesitation.

Step 6: Perform Self-Rescue If You Are Choking Alone

If you're choking and no one else is nearby, you can still perform abdominal thrusts on yourself. Make a fist and press the thumb side into your abdomen in the same spot you'd use on someone else: above your navel and below your ribcage. Grasp your fist with your other hand and thrust sharply inward and upward, repeating until the object clears.

If your fist alone isn't generating enough force, use a firm, stable object instead. Bend over the back of a sturdy chair, a countertop edge, or a railing, positioning the edge against the same spot above your navel, and press your body down and forward onto it with quick, deliberate motions to mimic the upward thrust of a standard abdominal thrust. Avoid anything with sharp corners or anything unstable that could tip or slide.

Even while attempting self-rescue, try to call 911 or shout for help before your symptoms worsen and you lose the ability to speak or dial a phone. If you're at work, home, or in public, alerting someone nearby, even with just a gesture toward your throat, means help can arrive or take over if your own attempts don't succeed. Don't wait until you're several thrusts in to consider getting attention; make noise and reach for your phone as soon as you recognize the obstruction is severe.

Step 7: Check the Person and Seek Medical Follow-Up

Once the object has been expelled and the person is breathing and coughing normally, the emergency isn't necessarily over. Abdominal thrusts and chest thrusts, even performed correctly, can cause internal bruising, rib injury, or in rare cases more serious internal harm. For this reason, anyone who has received abdominal thrusts, or an infant who has received back blows and chest thrusts, should be evaluated by a medical professional afterward, even if they seem fully recovered.

In the hours following the event, watch for signs that something wasn't fully resolved: continued coughing, a persistent feeling that something is still stuck, difficulty swallowing, pain when breathing, or any new trouble breathing at all. These can indicate a partial obstruction that wasn't fully cleared, swelling in the airway, or injury from the rescue effort itself. Any of these symptoms warrants a trip to urgent care or an emergency department rather than a wait-and-see approach.

Reading through these steps gives you a mental map of what to do, but choking rescue techniques are physical skills that need to be practiced with your hands, not just understood in theory. Knowing where to place a fist, how much force an infant chest thrust actually requires, and how to move smoothly between back blows and chest thrusts is difficult to internalize from text alone. Enrolling in a certified CPR and First Aid course lets you practice on training manikins under an instructor's guidance, correcting hand placement and thrust technique in real time so the motions become familiar before you ever need them for real.

Building Confidence Before an Emergency Happens

Knowing these choking rescue steps can mean the difference between life and death, but reading about them is only the first part of being prepared. Muscle memory, the kind that lets you act in seconds without pausing to recall the exact hand placement or thrust sequence, only comes from hands-on practice. A certified course also covers how choking response fits alongside CPR and AED use, so you're ready for whatever an emergency actually calls for, not just the scenario you happened to read about.

Don't wait until an emergency happens, equip yourself and your team with life-saving skills today. Schedule your CPR certification class now and gain the confidence to respond when every second counts.
