When the airway (wind pipe) is obstructed, such as choking on an object or piece of food. This can also occur when a baby is born and the airway is plugged with mucous.
It is used when a person is choking on food or a swallowed object, which is blocking the airway to the lungs. The Heimlich compression is an effort to dislodge and regurgitate the food or other object from the throat.
An airway that is not blocked. If you can breathe easily, you have an active airway. If you are choking, you do not.
Choking can be explained as an airway obstruction.
The most common cause of airway occlusion (airway obstruction) is choking on foreign objects. This means swallowing an obstructive object or having something lodged in your trachea causing the airway to lose its patency.

^ Please elaborate on the question ^ What happens when someone is choking? A foreign object is trapped in the airway, causing a complete blockage of airflow to or from the lungs. The object needs to be removed immediately or the body could lose oxygen and die. What should one do when choking? The universal sign for choking is both arms crossed over the chest, with hands on the shoulders or neck. The Heimlich maneuver is used to dislodge foreign objects from the airway by quickly pressing on the area a few inches above the belly button, pushing air out of the lungs quickly.
airway obstruction
If an object gets stuck in the right bronchus, choking may occur due to its narrower and more vertical angle compared to the left bronchus. This can lead to more obstruction and difficulty in dislodging the object, making it more likely to cause choking.
Any object that ends up in the airway will become stuck as the airway narrows. Many large objects get stuck just inside the trachea at the vocal cords. For adults, one of the main reasons for choking is chewed that isn't chewed properly (esp. swallowed whole)
An unobstructed airway.
