What should you do if a foreign object is visible in the airway of an adult or child?

In the situation where a foreign object is visible in the airway of an adult or child, the appropriate action is to perform a finger sweep to remove the obstruction, but only if the object is easily reachable and visible. This technique involves using your fingers to carefully dislodge the object, ensuring that you do not push it further down the airway in an effort to remove it. It is important to approach this with caution and to only attempt it if you can clearly see the object and can safely grasp it.

In cases where the object is not visible or not easily removed, abdominal thrusts would be the action taken for a severe obstruction, while rescue breaths should not be given if the airway is blocked. Additionally, waiting for emergency medical services without trying to clear the airway can lead to life-threatening situations, hence immediate action is necessary when something is lodged in the airway.
