Etiology. Wheezing occurs during the prolonged expiratory phase by the rapid passage of air through airways that are narrowed to the point of closure. Children wheeze more often than adults because of physical differences. Infants' and young children's bronchi are small, resulting in higher peripheral airway resistance ...

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 medicine helps with wheezing?
A bronchodilator -- albuterol (Proventil HFA, Ventolin HFA), levalbuterol, (Xopenex) -- to help ease the wheezing as the infection clears. An antibiotic is usually not needed unless you have an underlying chronic lung problem or your doctor suspects a bacterial infection may be present.

1 Wheezes are common occurrences during acute episodes of air- way obstruction but can also be heard in normal subjects during forced expiratory maneuvers.
What is forced expiratory wheeze?
Forced expiratory wheezes are produced by most normal individuals near the end of a maximal expiratory effort and are detected only when expiratory flows are maximal (15). Those data suggest that airway flow limitation is necessary for FEW to occur. However, further studies are needed to verify this important linkage.

Why is the expiratory phase longer than the inspiratory phase?
Question 2. The duration of inspiration is longer than the duration of expiration. The ribs and intercostal muscles filter out the expiratory sound more than the inspiratory sound.
Is inspiratory phase longer than expiratory?
The inspiratory phase lasts longer than the expiratory phase with a ration (I:E) of 2:1. Bronchial Breathing Breath sounds heard close to large air passages have a louder and longer expiratory phase and their energy components extend over a broad frequency range (<200 – 4000 Hz).
What causes prolonged expiratory phase and wheezing?
Respiratory muscles normally relax during exhalation, but during an asthma attack accessory muscles are needed to push air out. This causes a prolonged expiratory phase, and wheezing from turbulent airflow through constricted airways.
