69c5 Responding to Choking and Breathing Emergencies | Recognizing When Someone Is Choking, and Continuing Support Until Professional Help Takes Over
Choking and breathing emergencies can become life-threatening quickly, so the first task is to recognize whether air is still moving and whether the person can cough, speak, or breathe normally. The correct response depends on the person's condition, the helper's training, local emergency guidance, and whether the person becomes unresponsive.
This section develops practical judgment around effective coughing, severe choking, abnormal breathing, emergency activation, trained choking or CPR instructions, and staying with the person until professional responders can take over.
69c5.1 Recognizing When Someone Is Choking
Choking happens when the airway is blocked and air cannot move normally. A person with a partial blockage may still cough, speak, or make sounds, while severe choking can make speaking, effective coughing, or normal breathing impossible. They may look frightened, clutch the throat, make little or no sound, or begin to turn pale or bluish as oxygen falls.
Ask a responsive person if they are choking and pay attention to whether the cough is strong and air is moving. Do not confuse noisy distress with effective breathing; a weak or silent cough is more concerning. If the person can cough forcefully, encourage that effort and stay ready to act if it becomes ineffective. If they cannot breathe, speak, or cough effectively, get emergency help immediately and use the choking procedure appropriate to your training and local guidance. Rapid recognition matters because a severe airway blockage can worsen within minutes. If the person becomes unresponsive, support them to the ground to reduce injury from falling.
69c5.2 Encouraging Effective Coughing When Air Is Still Moving
When a choking person can still cough forcefully and move air, coughing may be the best way to clear the object. Encourage them to keep coughing and stay close enough to notice any change. Do not give food or drink, reach blindly into the mouth, or use forceful choking maneuvers while the cough remains clearly effective, because unnecessary interference can push an object deeper or cause injury.
Watch for the cough becoming weak or silent, inability to speak, increasing breathing difficulty, exhaustion, or loss of consciousness. These changes mean the obstruction may have become severe and emergency action is needed.
If the person clears the object but continues to cough, has trouble breathing or swallowing, or feels that something remains stuck, medical assessment may still be appropriate. Effective coughing is an active first-aid response, but it requires close observation so that a worsening airway problem is recognized without delay. Do not leave the person alone while the obstruction is still suspected.
69c5.3 Getting Immediate Help for Severe Choking
Severe choking is an emergency. If a person cannot breathe, speak, or cough effectively, call emergency services immediately or direct a specific person nearby to make the call. Begin the recognized choking response that matches the person's age, condition, and your current training, and follow dispatcher instructions when available. Techniques differ for adults, children, infants, pregnant people, and some larger bodies, so a single improvised method is not suitable for everyone.
Do not perform blind finger sweeps inside the mouth; remove an object only if you can clearly see it and can take it out safely. If the person becomes unresponsive, lower them carefully and move to the emergency response for an unconscious casualty, including CPR if trained or instructed. Continue until the airway clears, the person breathes normally, or professional help takes over. Fast activation of trained help is as important as the physical first-aid actions. Watch closely for unconsciousness or worsening breathing difficulty.
69c5.4 Responding When a Person Cannot Breathe Normally
A person who cannot breathe normally may be choking, having a severe asthma attack, severe allergic reaction, heart or lung problem, poisoning, injury, or another emergency. Look for whether the person can speak, how hard they are working to breathe, any unusual sounds, skin color changes, collapse, or reduced alertness. Do not spend valuable time trying to identify the exact diagnosis before seeking help when breathing is severely affected.
Call emergency services and help the person use their own prescribed emergency treatment if they are able and you understand how to assist, such as an inhaler or adrenaline auto-injector. Do not give someone else's medicine. Keep them in a position that makes breathing easier unless they become unconscious. If they stop breathing normally, follow CPR or dispatcher guidance. Severe breathing difficulty can deteriorate rapidly, so the first-aid goal is to support the person and connect them quickly with professional care.
69c5.5 Following Trained Emergency Instructions for Choking or CPR
Choking procedures and CPR are practical skills that are safest when learned through recognized hands-on training. In an emergency, call for professional help and follow instructions from the dispatcher, who can guide actions based on the person's age, responsiveness, and breathing. If you have current training, use the method you were taught rather than mixing steps remembered from different sources.
CPR guidance can change over time and may differ for adults, children, and infants. The same is true for choking techniques. If an unresponsive person is not breathing normally, start the emergency response you are trained or instructed to provide and use an automated external defibrillator if one is available and you know or are guided how to use it. Do not delay action while trying to recall every detail perfectly. Calling early, listening carefully, and following recognized instructions gives the person the best chance of receiving effective support until responders arrive.
69c5.6 Continuing Support Until Professional Help Takes Over
After the immediate choking or breathing action begins, keep supporting the person until they recover normally or trained responders take over. Continue to watch breathing, responsiveness, skin color, and ability to speak. If the person becomes unconscious or stops breathing normally, move immediately to the appropriate emergency response and follow dispatcher or CPR guidance.
Do not leave a recently recovered person alone simply because the frightening moment has passed. Choking maneuvers, a severe breathing episode, or the original obstruction can leave ongoing problems such as chest pain, persistent coughing, swallowing difficulty, wheezing, or a feeling that something remains in the airway. These symptoms deserve medical assessment. When responders arrive, tell them what happened, what actions were taken, whether the person lost consciousness, and what changes you observed. Clear handover allows professional care to continue without losing important information.
