What to Do Before Giving Breaths to an Unresponsive Choking Person

Before giving breaths to an unresponsive choking person, call emergency services, place the person on a firm flat surface, start CPR with chest compressions, then open the mouth and look for a visible object. If you see a loose object, remove it carefully. If you do not see an object, do not do a blind finger sweep.

This is a serious emergency. A choking person who becomes unresponsive may not be getting enough oxygen, and quick action can save a life.

The key step before giving breaths is to check the mouth for a visible obstruction and remove it only if you can clearly see it and it is loose enough to remove safely.

The Short Answer

If a choking person becomes unresponsive, the response changes from back blows and abdominal thrusts to CPR.

Before giving breaths, you should:

• Call 911 or tell someone else to call
• Lower the person carefully to the ground
• Place them on their back on a firm, flat surface
• Begin CPR, starting with chest compressions
• After compressions, open the airway
• Open the mouth and look for a visible object
• Remove the object only if you can see it and it is loose
• Avoid blind finger sweeps
• Attempt breaths only after checking the mouth and opening the airway

The reason is simple: chest compressions may help move the object upward, but blindly reaching into the mouth can push the object deeper.

Call for Emergency Help First

An unresponsive choking person needs emergency medical help. If another person is nearby, point to them and say clearly, “Call 911 now.” If an automated external defibrillator, or AED, is available, send someone to get it.

If you are alone, call 911 as soon as you can. Put the phone on speaker so the dispatcher can guide you while you continue care.

Do not spend time searching online, driving the person somewhere, or trying many unproven methods. Choking can block oxygen quickly, and emergency responders may need to provide advanced airway care.

If the person is still conscious and choking, first-aid guidance may include back blows and abdominal thrusts for adults and children over 1 year old. But once the person becomes unresponsive, CPR becomes the priority.

For broader emergency context, this guide on reasons to go to the emergency room explains why severe breathing and choking problems should not be delayed.

Place the Person on a Firm, Flat Surface

If the person collapses or becomes unresponsive, carefully lower them to the ground. Try to support the head and neck as you do this, especially if they fell or may have been injured.

Place them on their back on a firm, flat surface. A bed, couch, or soft chair is not ideal for compressions because the body sinks into the surface. The floor is usually better.

Expose the chest enough to place your hands correctly for CPR and to see chest movement when breaths are attempted. If clothing is in the way, move it enough to provide care.

Do not continue abdominal thrusts on an unresponsive person. For an unresponsive choking person, chest compressions are used instead.

If you are not trained in rescue breaths, emergency dispatchers may tell you to perform hands-only CPR until help arrives. Follow their instructions.

Start CPR with Chest Compressions

For an unresponsive choking adult or child, authoritative first-aid guidance says to begin CPR, starting with chest compressions.

Chest compressions are important because they circulate blood and may also help move the stuck object. In choking, compressions can create pressure changes in the chest that may help dislodge the obstruction.

If you are trained in CPR, use the steps you learned in your certified course. For adults, CPR commonly involves cycles of 30 chest compressions followed by 2 rescue breaths. For children and infants, details can differ based on age, number of rescuers, and training level.

If you are not trained, place your hands in the center of the chest and push hard and fast, following dispatcher instructions. Any effective action is better than standing frozen during a life-threatening emergency.

Do not pause for long. Long interruptions reduce the benefit of CPR.

Check the Mouth Before Giving Breaths

After a set of chest compressions, open the person’s mouth and look for the object before attempting breaths.

This step matters because compressions may move the object into the mouth where it can be removed. If the object is now visible and loose, remove it carefully with your finger.

But if you cannot see the object, do not sweep your finger inside the mouth. A blind finger sweep can push the object farther into the airway, damage tissues, trigger vomiting, or make the blockage worse.

The safe rule is:

• If you see a loose object, remove it
• If you do not see an object, do not reach blindly
• If the object looks deeply lodged, do not force it

After checking the mouth, open the airway with the head-tilt, chin-lift method if you are trained and there is no suspected neck injury. Then attempt breaths according to your CPR training.

If the breath does not go in or the chest does not rise, reposition the airway and try again if your training says to do so. Then return to compressions.

Why Blind Finger Sweeps Are Dangerous

Blind finger sweeps are dangerous because you cannot know where the object is or how it is positioned. Reaching into the throat without seeing the object can push it deeper.

This can turn a partial blockage into a complete blockage, or make a complete blockage harder for rescuers to clear. It can also injure the mouth or throat.

That is why Red Cross and MedlinePlus guidance emphasizes removing an object only when it is visible. The object must be seen before you try to remove it.

This is one of the most important details in choking first aid. People often panic and try to dig around in the mouth. Panic is understandable, but it can make the situation worse.

Slow the action down just enough to follow the sequence: compressions, open mouth, look, remove only if visible, open airway, try breaths, then continue CPR.

What If the Breath Does Not Go In?

If you give a breath and the chest does not rise, the airway may still be blocked or the head position may not be correct.

If you are trained, reposition the head and chin, create a better seal, and try another breath according to your CPR training. If the breath still does not go in, return to chest compressions.

After the next set of compressions, check the mouth again before attempting breaths. If you see the object, remove it. If you do not see it, do not sweep.

Continue cycles of CPR, checking for a visible object before breaths, until emergency help arrives, the person starts breathing normally, an AED prompts you to pause, or you are too exhausted to continue.

If the object comes out and the person begins breathing, keep them still and monitor them until emergency help arrives. They still need medical evaluation because choking and first-aid efforts can cause complications.

Adults, Children, and Infants

This article mainly explains the general idea of what to do before breaths in an unresponsive choking person, but age matters.

For adults and children over 1 year old who are conscious and choking, current guidance commonly uses cycles of back blows and abdominal thrusts until the object comes out or the person becomes unresponsive.

For infants, abdominal thrusts are not recommended. Infant choking first aid uses back blows and chest thrusts while the infant is conscious. If the infant becomes unresponsive, infant CPR is used.

Because the steps differ by age, taking a certified first-aid and CPR class is strongly recommended. A class lets you practice hand placement, compression depth, rescue breaths, AED use, and choking response on manikins.

Reading helps, but practice builds confidence.

Common Mistakes to Avoid

One mistake is continuing abdominal thrusts after the person becomes unresponsive. Once the person is unresponsive, begin CPR.

Another mistake is delaying the emergency call. Choking can become fatal quickly. Call for help early.

A third mistake is performing blind finger sweeps. Only remove an object you can actually see.

Other mistakes include giving up too soon, moving the person unnecessarily, attempting to give water, shaking the person, or spending too long trying to make breaths work before returning to compressions.

Do not put food or drink in the person’s mouth. Do not try to force the person to stand. Do not assume they are fine just because the object comes out. Anyone who had severe choking or became unresponsive needs medical attention.

If breathing difficulty continues after the object comes out, read possible signs of difficulty breathing and seek emergency care if warning signs are present.

Why Training Matters

Choking emergencies are frightening because they move fast. Training gives you a sequence to follow when panic wants to take over.

A certified class can teach you how to recognize choking, give back blows, give abdominal thrusts, respond when a person becomes unresponsive, perform CPR, use an AED, and adjust care for adults, children, and infants.

Training also teaches you what not to do. That matters because good intentions can be harmful if the wrong action pushes the object deeper or delays CPR.

If you live with children, care for older adults, work in food service, supervise students, coach sports, teach, babysit, or spend time around people with swallowing problems, first-aid training is especially valuable.

Keep emergency numbers visible, know your location when calling for help, and refresh your CPR training regularly.

Final Thoughts

Before giving breaths to an unresponsive choking person, call emergency services, place the person on a firm flat surface, start CPR with chest compressions, and check the mouth for a visible object before breaths. Remove the object only if you can see it and it is loose.

Do not do blind finger sweeps. Do not delay CPR. Keep going until emergency help arrives or the person starts breathing normally.

The best preparation is hands-on CPR and first-aid training. In a real emergency, that training can help you act quickly, calmly, and safely.
