Gags, or choking, occur when an object becomes lodged in the throat, blocking airflow. This can happen with food, small toys, or other items. When choking occurs, the person may struggle to breathe, cough, or make a high-pitched sound. It is a medical emergency that requires immediate attention. To help someone who is choking, the Heimlich maneuver can be performed. This involves applying pressure to the abdomen to expel the object. If the person becomes unconscious, calling emergency services and starting CPR may be necessary. Knowing how to respond can save a life in such situations.
