Wheezes are a continuous breath sound with a musical tone. They may be either low or high-pitched. low-pitched wheezes have a moaning or snoring sound. High-pitched wheezes can be compared to a squeaking sound. Wheezes may be auscultated over anterior, posterior pr lateral chest walls. Wheezes are more intense over lung areas affected by partial obstructions.




In this case, expiratory wheezes are heard over most of the chest wall. This may indicate widespread airflow obstruction, for example in patients with asthma. Use the slider to the right to reveal the lungs.
