Study Notes
Normal Breath Sounds
- Three main types: Vesicular, Bronchial (or Tracheal), and Bronchovesicular.
Vesicular Breath Sounds
- Characterized by soft, low-pitched, fine rustling sounds.
- Found predominantly over the lung periphery.
- Louder during inspiration; soft or absent during expiration.
- Most common breath sound; decreased intensity may suggest pneumonia, emphysema, pleural effusion, or atelectasis.
Bronchial or Tracheal Breath Sounds
- Identified by loud, high-pitched, tubular sounds.
- Located over the trachea (suprasternal area) and major bronchi.
- Louder and longer during expiration.
- Detection over the periphery may indicate consolidation or atelectasis.
Bronchovesicular Breath Sounds
- Exhibit moderately pitched sounds.
- Found between the scapulae posteriorly and at the 1st and 2nd intercostal spaces (ICS) anteriorly.
- No pause between inspiration and expiration.
- If present over the periphery, may indicate consolidation (lungs filled with exudate).
Inaudible Breath Sounds
- May signify conditions such as atelectasis or pneumothorax.
