Choking: What To Do
An obstructed airway, and what to do in the first seconds.
Last revised
A complete obstruction kills within minutes, and the response differs by age in a way that matters.
Key takeaways
- Mild: can speak, cough or breathe — encourage coughing
- Severe: cannot speak, cough or breathe — act immediately
- Most useful single change: Encourage coughing while they still can.
- Commonest mistake: Abdominal thrusts on a baby under one.
- See a doctor if any of the signs under "When to get help" below apply to you.
Do
- Encourage coughing while they still can
- Lean them forward for back blows
- Call 999 as soon as the obstruction is severe
Do not
- Abdominal thrusts on a baby under one
- Slapping the back of someone who is coughing effectively

When to get help
Call 999 immediately for severe choking, and start CPR if the person becomes unresponsive. Always seek medical assessment after abdominal thrusts because of the risk of internal injury, and for a persistent cough or a sensation that something is still stuck.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
