Recognising and Responding to a Choking Emergency
Choking can change from a person coughing over a mouthful of food to a life-threatening airway emergency in a very short time. The first challenge is recognising which situation you are dealing with.
Someone who can still cough effectively may be able to clear the obstruction themselves. Someone who suddenly becomes silent, cannot breathe properly or can no longer produce an effective cough needs immediate help.
The response should be simple enough to remember under pressure: recognise when the cough is no longer effective, use the correct choking sequence for the person’s age, call for emergency help and be ready to move into CPR if they become unresponsive.
Recognise when coughing is still effective
A person with a partial airway obstruction may still be able to speak, breathe and cough. The cough can sound forceful or distressed, but if it remains effective, encourage them to keep coughing and stay close by in case their condition changes.
Do not immediately start back blows or abdominal thrusts while the person is coughing effectively. Their own cough is capable of generating considerable pressure and may clear the obstruction without further intervention.
What matters is watching for deterioration.
A cough that becomes weak, quiet or ineffective changes the situation. The person may stop being able to speak, breathing may become difficult or impossible, and they may appear increasingly distressed. Some people make very little noise despite having a severe obstruction.
If someone suddenly becomes unable to speak or cough, particularly while eating, choking should be considered immediately.
What to do when an adult or child over one is choking
When coughing is no longer effective, give up to five back blows.
Lean the person forwards and deliver firm blows between the shoulder blades with the heel of your hand. Check after each blow rather than automatically giving all five. If the obstruction clears, stop.
If back blows do not clear the airway, give up to five abdominal thrusts.
Stand behind the person and put your arms around the upper part of their abdomen. Make a fist and place it between the navel and the bottom of the breastbone. Grasp your fist with your other hand and pull sharply inwards and upwards.
Again, check after each thrust.
If the obstruction has still not cleared, continue alternating:
- Up to five back blows
- Up to five abdominal thrusts
Call 999 and continue the sequence until the obstruction clears, emergency help takes over or the person becomes unresponsive.
A blind finger sweep should not be used. If an object can be clearly seen in the mouth and removed easily, it can be taken out, but repeatedly putting fingers into the mouth without seeing the obstruction risks pushing it further into the airway.
Do not assume silence means the person is getting better
This is one of the easiest signs to misread.
A person who was coughing loudly and suddenly becomes quiet may not be improving. They may have lost the ability to move enough air to cough or speak.
Look at the whole picture.
Can they answer you? Can they breathe? Is the cough still strong? Are they becoming weak, confused or less responsive?
Choking often happens in noisy environments such as dining rooms, staff areas, restaurants or care settings. The person may also be seated away from whoever first notices them. Recognising the change quickly matters more than waiting for the classic image of somebody clutching their throat.
Choking in an infant needs a different technique
Babies under one year should not receive abdominal thrusts.
If an infant has an ineffective cough and a severe airway obstruction, give up to five back blows.
Support the infant securely with their head lower than their chest and give a firm blow between the shoulder blades. Check whether the obstruction has cleared after each attempt.
If the back blows are unsuccessful, turn the infant onto their back while continuing to support them and give up to five chest thrusts.
Current Resuscitation Council UK paediatric guidance uses a two-thumb encircling technique for these chest thrusts. Both thumbs are placed over the lower half of the breastbone, with the hands encircling and supporting the infant’s chest, and the thrust is delivered more sharply than a normal chest compression.
Continue alternating up to five back blows and up to five chest thrusts while the infant remains conscious and the obstruction remains.
This is an important change from older teaching that used two fingers for infant chest thrusts. Training and local resources should therefore reflect the current 2025 paediatric resuscitation guidance.
What if the person is pregnant?
Abdominal thrusts should not be performed on a pregnant person.
If somebody is pregnant, or if their size makes it impossible to encircle the abdomen effectively, chest thrusts can be used instead.
Stand behind the person as you would for abdominal thrusts, but position your hands higher over the lower end of the breastbone and use sharp inward thrusts.
The principle remains the same: back blows first, followed by an appropriate thrust technique if the obstruction has not cleared.
If an adult becomes unresponsive
If an adult who is choking becomes unresponsive, lower them carefully and begin CPR. Make sure 999 has been called.
Start chest compressions without delaying to repeatedly search the mouth for the obstruction. Each time the airway is opened for rescue breaths, look for a clearly visible object and remove it only if it can be reached easily.
Do not perform blind finger sweeps.
If an AED is available, bring it to the casualty and use it in the normal way. The AED will not remove an airway obstruction, but a person who has become unresponsive and is not breathing normally should receive the usual resuscitation response while emergency help is on its way.
If a child or infant becomes unresponsive
Paediatric resuscitation has important differences.
If an infant or child becomes unconscious during a choking episode, open the airway and attempt five rescue breaths, removing an obstruction only if it is clearly visible and easy to reach.
Then continue with paediatric basic life support according to the level of training of the rescuer.
Healthcare professionals specifically trained in paediatric basic life support may use the full paediatric sequence, while people trained primarily in adult BLS may follow the recognised paediatric modifications.
The important point is that paediatric choking should not simply be treated as a smaller version of the adult response. The initial rescue breaths and age-appropriate techniques matter.
After the obstruction has cleared
Relief when somebody starts breathing or speaking again can make it tempting to treat the incident as finished.
Sometimes it is not.
A person who has needed abdominal thrusts or chest compressions during a choking emergency should be assessed by a healthcare practitioner because these interventions can cause injury.
Further assessment is also sensible if the person continues to experience problems such as:
- Persistent coughing
- Difficulty swallowing
- Chest or abdominal pain
- Breathing difficulty
- A feeling that something remains stuck
- Any deterioration after initially appearing to recover
Someone who became unresponsive or required CPR will already need emergency medical assessment.
In a healthcare or care setting, the incident should also be documented according to local procedures, including what happened, what interventions were required and how the person responded.
Choking can look different in a care setting
Care homes and supported-living services deserve particular attention because some residents have a much higher underlying choking risk.
Swallowing difficulties, neurological disease, dementia, frailty, poor dentition and difficulties maintaining an appropriate eating position can all affect risk. Some residents may also be unable to clearly explain that something is stuck.
The immediate first-aid response remains important, but prevention starts much earlier.
Where a resident has known swallowing difficulties, staff should follow their individual assessment and any agreed food or fluid texture recommendations. Changes to eating, coughing during meals, repeated chest infections or new difficulties swallowing should not simply be accepted as part of ageing.
During an actual choking emergency, however, staff need to recognise quickly whether the resident still has an effective cough and move into the appropriate choking sequence if it becomes ineffective.
Dental settings have their own choking risks
Food is not the only cause of airway obstruction.
Dental practices work with small instruments, restorations and other materials close to the airway. Good clinical precautions reduce the risk of aspiration or choking, but teams still need to know what they would do if an object enters the airway.
The dental chair can also affect positioning and access. If the patient is choking, treatment stops and the team needs enough space to assess them and carry out the appropriate intervention without instruments and equipment remaining in the way.
If the event progresses to unresponsiveness, the response then moves into resuscitation and the practice’s normal emergency arrangements.
Be careful with anti-choking suction devices
Suction-based airway clearance devices are now marketed for use during choking emergencies, but they should not distract from the recognised first-aid sequence.
Resuscitation Council UK reviewed its position again in 2026 and currently makes no recommendation either for or against these devices because there is not enough high-quality evidence about their safety and effectiveness.
The important practical point is that established choking treatment should not be delayed while somebody finds or prepares a specialist device.
Encouraging an effective cough, using back blows and the appropriate thrust technique, and moving promptly to CPR if the casualty becomes unresponsive remain the recognised response.
Practice the transition from choking to CPR
Most people can remember that choking involves back blows and thrusts. The harder part is recognising when one stage of the emergency has become another.
A casualty may start with an effective cough, lose the ability to cough properly, deteriorate despite back blows and thrusts, and then become unresponsive.
Training should make that progression familiar.
For staff whose role includes first response, Basic Life Support and AED training gives learners the opportunity to practise choking management alongside CPR and AED use, rather than treating them as completely separate emergencies.
That physical practice matters. Giving a back blow, positioning an infant safely and moving from airway-obstruction treatment into resuscitation are difficult skills to learn properly from written instructions alone.
Do not make the response more complicated than it needs to be
Choking is frightening partly because there is so little time to stop and think.
A clear sequence helps.
If the person can still cough effectively, encourage them to cough and watch closely. If the cough becomes ineffective, move to back blows and then the correct thrust technique for their age and circumstances. Call for emergency help, keep reassessing and start the appropriate resuscitation response immediately if they become unresponsive.
What changes between an adult, child and infant is important. What does not change is the need to recognise deterioration quickly and act rather than waiting for the obstruction to become complete.
That is what makes choking management worth practising. The aim is not to memorise a long list of instructions. It is to know what you are seeing, what comes next and when the response needs to change.
FAQs About Choking Emergencies
Can someone choke on tablets or medication?
Yes. Tablets and capsules can become lodged in the airway, particularly in people who have swallowing difficulties or other factors that make eating and drinking more difficult. Repeated problems swallowing medication should be raised with an appropriate healthcare professional so the person’s medicines and swallowing needs can be reviewed.
What is the difference between choking and aspiration?
Choking happens when an object or material blocks the airway and prevents normal breathing. Aspiration occurs when food, fluid, saliva or another substance enters the airway or lungs. Aspiration does not always cause a complete blockage, but it can lead to coughing, breathing problems or complications that require clinical assessment.
Should you give someone water if they are choking?
No. Food or drink should not be used to try to push an obstruction down during an active choking episode. The priority is to assess whether the person’s cough is effective and use the recognised choking first-aid response if it becomes ineffective.
What should happen if someone has repeated choking episodes?
Repeated choking should not simply be treated as a series of unrelated incidents. The person may need a review of their swallowing, medicines, eating and drinking arrangements or wider health needs. In health and care settings, concerns should be raised through the appropriate clinical pathway so any underlying risk can be assessed and the care plan updated where necessary.
Can someone choke on soft food?
Yes. Choking is not limited to hard or solid foods. Soft food, poorly chewed food and other material can obstruct the airway, particularly where swallowing is impaired. Any prescribed texture or swallowing recommendations should therefore be followed carefully rather than assuming softer food removes the risk completely.
