=== Choking ===
{{See also|Choking#Treatment}}
Choking occurs when a foreign body obstructs the trachea. Rescuers should only intervene in patients who show signs of severe airway obstruction, such as a silent cough, cyanosis, or inability to speak or breathe. If a patient is coughing forcefully, rescuers should not interfere with this process and encourage the patient to keep coughing. If a patient shows signs of severe airway obstruction, anti-choking maneuvers such as back slaps or in the most severe cases [[abdominal thrusts]] should be applied until the obstruction is relieved. If a patient becomes unresponsive he should be lowered to the ground, and the rescuer should call emergency medical services and initiate CPR. When the airway is opened during CPR, the rescuer should look into the mouth for an object causing obstruction, and remove with a finger sweep it if it is evident however many organisations state that the rescuer should not try to remove the foreign object as they might worsen the situation (either pushing it further down the trachea or initiating vomiting).{{citation needed|date=March 2020}}
