Overview

By Mayo Clinic Staff

Choking happens when an object lodges in the throat or windpipe blocking the flow of air. In adults, a piece of food is usually to blame. Young children often choke on small objects. Choking is life-threatening. It cuts off oxygen to the brain.

Give first aid as quickly as possible if you or someone else is choking. To prepare yourself for these situations, learn the Heimlich maneuver and CPR in a certified first-aid training course.
