A member asked:

In status asthmaticus, what is the cause of inspiratory wheezing?

Airway constriction: With any asthma attack, the airway is constricted, which increases the flow velocity and causes the noise, which we call wheezing. Of course the real problem is the increased work of breathing and decreased oxygenation. Medications open the airway, decreasing the flow velocity, reducing the noise and allowing you to breath easier.

Wheezing...: Wheezing is caused by air flowing in a partially obstructed bronchial tube. If the tube is completely obstructed, there is no sound and if it is wide open, there is the normal airflow sound.
