What can untreated airway obstruction lead to?

How do you clear a blocked windpipe?
A person who cannot speak, cough, or breathe may require the Heimlich maneuver. This procedure, also known as abdominal thrusts, involves forcefully applying pressure to the abdomen to dislodge a blockage in the windpipe.
What sound would a lower airway obstruction produce?
Severe obstruction of the intrathoracic lower airway or upper airways obstruction can be associated with inspiratory wheezes. Asthma and chronic obstructive pulmonary diseases (COPD) patients develop generalized airway obstruction; therefore, wheezes are heard all over the chest.
Can narrowing of airways be reversed?
In asthma, the narrowing is reversible, meaning that with appropriate treatment or on their own, the muscular contractions of the airways stop, inflammation resolves so that the airways widen again, and airflow into and out of the lungs returns to normal.
What happens if your airway is narrow?
Laryngotracheal stenosis, or airway stenosis, is the narrowing of the trachea, often called the windpipe, which connects the nose and mouth to the lungs. This narrowing results in difficulty breathing and can also make cold symptoms worse and impact the voice and the ability to swallow.
How do I widen my airways?

What happens when your windpipe is blocked?

What factors are responsible for airway narrowing in asthma?
Narrowing of the airways is often caused by abnormal sensitivity of cholinergic receptors, which cause the muscles of the airways to contract when they should not. Certain cells in the airways, particularly mast cells , are thought to be responsible for initiating the response.
What does Laryngospasm feel like?
