Lesson

For heart sounds listen to the synthetic sound while reviewing this lesson.

Wheezes are adventitious lung sounds that are continuous with a musical quality. Wheezes can be high or low pitched. High pitched wheezes may have an auscultation sound similar to squeaking. Lower pitched wheezes have a snoring or moaning quality.

The proportion of the respiratory cycle occupied by the wheeze roughly corresponds to the degree of airway obstruction.

Wheezes are caused by narrowing of the airways.

The waveform(s) seen above are a chart of sound amplitude (loudness) on the vertical axis against time on the horizontal axis.
