Wheezes are believed to be generated by oscillations or vibrations of nearly closed airway walls. Air passing through a narrowed portion of an airway at high velocity produces decreased gas pressure and flow in the constricted region (according to Bernoulli's principle).
What is wheezing caused by?
Inflammation and narrowing of the airway in any location, from your throat out into your lungs, can result in wheezing. The most common causes of recurrent wheezing are asthma and chronic obstructive pulmonary disease (COPD), which both cause narrowing and spasms (bronchospasms) in the small airways of your lungs.
What are the 3 main causes of wheezing?
Wheezing happens when the airways are tightened, blocked, or inflamed, making a person's breathing sound like whistling or squeaking. Common causes include a cold, asthma, allergies, or more serious conditions, such as chronic obstructive pulmonary disease (COPD).
