Which of the following is NOT classified as a normal breath sound?

1. Bronchial

2. Bronchovesicular

3. Vesicular

4. Creaking

The correct answer is: Creaking

The classification of normal breath sounds is essential for effective respiratory assessment. Bronchial, bronchovesicular, and vesicular sounds are all considered normal breath sounds that reflect healthy lung function. Bronchial sounds are typically heard over the trachea and are characterized by a tubular quality. They are loud and high-pitched, with a noticeable pause between inspiration and expiration. Bronchovesicular sounds, found over mainstem bronchi, represent a blend of the two qualities and are of moderate intensity—a sign of air movement through the larger airways. Vesicular sounds occur over most lung fields and are soft, low-pitched, and gentle during inhalation, with no distinct pause between inspiration and expiration, indicating healthy alveolar airflow. In contrast, creaking is not categorized as a normal breath sound. It may indicate the presence of abnormal lung conditions or respiratory issues, such as pleural friction rubs, which arise from inflamed pleurae rubbing together. Recognizing the distinction between normal and abnormal breath sounds is crucial in clinical assessments, as it assists healthcare professionals in identifying potential respiratory problems.
