Detailed explanation-1: -Wheezing is the shrill whistle or coarse rattle you hear when your airway is partially blocked. It might be blocked because of an allergic reaction, a cold, bronchitis or allergies. Wheezing is also a symptom of asthma, pneumonia, heart failure and more.

Detailed explanation-2: -Wheezing may result from localized or diffuse airway narrowing or obstruction from the level of the larynx to the small bronchi. The airway narrowing may be caused by bronchoconstriction, mucosal edema, external compression, or partial obstruction by a tumor, foreign body, or tenacious secretions.

Detailed explanation-3: -In rare cases, wheezing may be heard both during inspiration and expiration. In severe asthma, no wheeze may be heard as the airflow will be so severely reduced, and chest auscultation will be silent.

Detailed explanation-4: -Inspiratory wheezing often accompanies expiratory wheezing when heard over the lungs, specifically in an acute exacerbation of asthma. When inspiratory wheezing is heard over the neck, this indicates a narrowing in the large, upper airways in the neck.
