Choking – unconscious adult or child over 1 year; First aid – choking – unconscious adult or child over 1 year; CPR – choking – unconscious adult or child over 1 year

Choking is when someone cannot breathe because food, a toy, or other object is blocking the throat or windpipe (airway).

A choking person’s airway may be blocked so that not enough oxygen reaches the lungs. Without oxygen, brain damage can occur in as little as 4 to 6 minutes. Rapid first aid for choking can save a person’s life.

This article discusses choking in adults or children over age 1 who have lost alertness (are unconscious).

Causes

Choking may be caused by:

Eating too fast, not chewing food well, or eating with dentures that do not fit well
Drinking alcohol (even a small amount of alcohol affects awareness)
Being unconscious and breathing in vomit
Breathing in or swallowing small objects (young children)
Injury to the head and face (for example, swelling, bleeding, or a deformity can cause choking)
Swallowing problems caused by a stroke or other brain disorders
Enlarging tonsils or tumors of the neck and throat
Problems with the esophagus (food pipe or swallowing tube)

Symptoms

Symptoms of choking when a person is an unconscious include:

Bluish color to the lips and nails
Inability to breathe

First Aid

Tell someone to call 911 or the local emergency number while you begin first aid and CPR.

If you are alone, shout for help and begin first aid and CPR.

Roll the person onto their back on a hard surface, keeping the back in a straight line while firmly supporting the head and neck. Expose the person’s chest.
Open the person’s mouth with your thumb and index finger, placing your thumb over the tongue and your index finger under the chin. If you can see an object and it is loose, remove it.
If you do not see an object, open the person’s airway by lifting the chin while tilting the head back.
Place your ear close to the person’s mouth and watch for chest movement. Look, listen, and feel for breathing for 5 seconds.
If the person is breathing, give first aid for unconsciousness.
If the person is not breathing, begin rescue breathing. Maintain the head position, close the person’s nostrils by pinching them with your thumb and index finger, and cover the person’s mouth tightly with your mouth. Give two slow, full breaths with a pause in between.
If the person’s chest does not rise, reposition the head and give two more breaths.
If the chest still does not rise, the airway is likely blocked, and you need to start CPR with chest compressions. The compressions may help relieve the blockage.
Do 30 chest compressions, open the person’s mouth to look for an object. If you see the object and it is loose, remove it.
If the object is removed, but the person has no pulse, begin CPR with chest compressions.
If you do not see an object, give two more rescue breaths. If the person’s chest still does not rise, keep going with cycles of chest compressions, checking for an object, and rescue breaths until medical help arrives or the person starts breathing on their own.

If the person starts having convulsions or seizures, give first aid for this problem.

After removing the object that caused the choking, keep the person still and get medical help. Anyone who is choking should have a medical examination. This is because the person can have complications not only from the choking but also from the first aid measures that were taken.

Do Not

Do NOT try to grasp an object that is lodged in the person‘s throat. This may push it farther down the airway. If you can see the object in the mouth, it may be removed.

When to Contact a Medical Professional

Seek medical help right away if someone is found unconscious.

In the days following a choking episode, contact a doctor right away if the person develops:

A cough that doesn’t go away
Pneumonia and fever
Shortness of breath
Wheezing

These could be signs that the object entered the lung instead of being expelled

Prevention

To prevent choking:

Eat slowly and chew food completely.
Do not drink too much alcohol before or during eating.
Keep small objects away from young children.
Make sure dentures fit properly.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

Write when the problem started and how it changed.
Bring old prescriptions, investigation reports, and current medicines.
Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

What is the most likely cause of my symptoms?
Which danger signs mean I should go to hospital quickly?
Which tests are necessary now, and which can wait?
How should I take medicines safely and what side effects should I watch for?
When should I come for follow-up?

Tests to discuss

Vital signs: temperature, pulse, blood pressure, oxygen saturation
Basic physical examination by a clinician

Safe first steps

Avoid heavy lifting, sudden bending, and prolonged bed rest.

Get urgent help if

Back pain with leg weakness, numbness around private area, loss of urine/stool control, fever, cancer history, or major injury needs urgent care.

Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Medicine doctor / pediatrician for children / qualified clinician

Tests to discuss with doctor

Temperature chart and hydration assessment
CBC with platelet count if fever persists or dengue/other infection is possible
Urine test, malaria/dengue tests, chest evaluation, or blood culture only when clinically indicated

Questions to ask

What is the most likely cause of my symptoms?
Which warning signs mean I should go to emergency care?
Which tests are really needed now?
Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?
Do I need antibiotics, or is this more likely viral?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Go to emergency care if you notice:

Severe or rapidly worsening symptoms
Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration

Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.

Step 1
Check danger signs first
If danger signs are present, seek emergency care and do not wait for online information.
Step 2
Record the symptom story
Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.
Step 3
Visit a qualified clinician
A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.
Step 4
Do only useful tests
Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.
Step 5
Follow up and return early if worse
If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips

Take a written symptom diary and all previous prescriptions/test reports.
Do not hide medicines already taken, even herbal or over-the-counter medicines.
Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
