If the airway is very reduced, breathing may be silent and not produce a wheezing sound. Your peak expiratory flow rate measures how fast you can exhale. It commonly occurs with conditions like asthma but can have other causes.Įxpiratory wheezing may indicate that your peak expiratory flow rate is reduced. If wheezing is loud enough, you may be able to hear it without using a stethoscope.Įxpiratory wheezing often indicates narrowing in the small airways or a mild blockage in all or part of your airway, known as an airway obstruction.
