== Dynamic Compression of the Airways ==

'''Dynamic compression of the airways''' (pronunciation: dy-nam-ic com-pres-sion of the air-ways) is a medical condition that involves the narrowing or obstruction of the [[airways]] during exhalation. This condition is often associated with [[chronic obstructive pulmonary disease]] (COPD) and [[asthma]].

=== Etymology ===

The term "dynamic" comes from the Greek word "dynamikos", which means powerful. "Compression" is derived from the Latin word "compressus", which means press together. "Airways" is a term used in medicine to refer to the tubes that carry air in and out of the lungs.

=== Definition ===

Dynamic compression of the airways is a phenomenon that occurs when the pressure inside the [[bronchi]] and [[bronchioles]] becomes greater than the pressure outside these structures, causing them to collapse and narrow during exhalation. This can lead to difficulty breathing, shortness of breath, and other respiratory symptoms.

=== Causes ===

Dynamic compression of the airways can be caused by several factors, including:

* [[Chronic obstructive pulmonary disease]] (COPD): This is a group of diseases that cause airflow blockage and breathing-related problems. COPD can cause the walls of the airways to become thick and inflamed, leading to dynamic compression.

* [[Asthma]]: This is a condition in which a person's airways become inflamed, narrow and swell, and produce extra mucus, which can make breathing difficult and trigger coughing, wheezing and shortness of breath. Asthma can also cause dynamic compression of the airways.

* [[Bronchiectasis]]: This is a condition that causes damage to the airways, leading to them becoming wider and flabbier than normal, which can lead to dynamic compression.

=== Treatment ===

Treatment for dynamic compression of the airways typically involves managing the underlying condition that is causing the compression. This may include medications to reduce inflammation and open up the airways, pulmonary rehabilitation, and in severe cases, surgery.
