Basics of Lung Sounds Wheeze 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. play pause Position: Chest wall Chestpiece: Diaphragm Maneuver: Seated Waveform Skin and Ribs Blended View Lungs Move slider to reveal lungs Table of Contents 1Vesicular - Normal 2Crackles - Fine (Rales) 3Crackles - Coarse (Rales) 4Wheeze 5Rhonchi - Low Pitched Wheezes 6Bronchial 7Pleural Rubs 8Bronchovesicular Practice Drill
