About Choking

Food or small objects can cause choking if they get caught in your throat and block your airway. This keeps oxygen from getting to your lungs and brain. If your brain goes without oxygen for more than four minutes, you could have brain damage or die.

Young children are at an especially high risk of choking. They can choke on foods like hot dogs, nuts and grapes, and on small objects like toy pieces and coins. Keep hazards out of their reach and supervise them when they eat.

When someone is choking, quick action can be lifesaving. Learn how to do back blows, the Heimlich maneuver (abdominal thrusts), and CPR.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Choking

58 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
