Choking emergencies occur when an object, often food, blocks the airway, preventing a person from breathing. This can lead to serious complications if not addressed quickly. Signs of choking include difficulty breathing, coughing, or a person clutching their throat. To help someone who is choking, the Heimlich maneuver can be performed. This involves standing behind the person, placing your arms around their waist, and delivering quick upward thrusts to dislodge the object. If the person becomes unconscious, it is essential to call emergency services immediately and begin CPR if trained to do so.
