Welcome to our website's expiratory wheeze page. On this page we provide a description of expiratory wheezing. We then provide an audio example of an expiratory wheeze. We also provide multiple links to the wheeze lung sound training lessons and reference pages available on this web site.
Expiratory wheeze is a continuous lung sound with a musical quality heard during expiration, although occassionally on inspiration. Wheezes are higher-pitched sounds. They are commonly caused by asthma, reactive airway disease, allergies, bronchitis, COPD, pneumonia, RSV, lung cancer, heart failure or a partial airway obstruction.
Wheezing is more common in children compared to the adult population.
Wheezing during inspiration as well as expiration indicates more severe airway narrowing or obstruction.
While we have many breath sound lessons and quick references on this website. Please use the links below.
Two lessons on wheezing sounds are part of our Basics of Lung Sounds course. We suggest taking the full course (about 15-20 minutes), but the lesson can be used without the full course. Our intermediate lung sounds course has additional types of wheezes: expiratory, monophonic and polyphonic.Basics of Lung Sounds
