Breath Sounds

Vesicular Normal breath sounds, bilateral (both sides)
Bronchial Normal sounds heard over the trachea or bronchi. These sounds heard over the lung periphery would indicate lung consolidation
Course Crackles A bubbling or crackling sound that can be heard during inspiration or expiration and produced by air flowing through airways containing fluid. Caused by fluid in lower airways that will not clear with coughing.
Rhonchi A bubbling or crackling sound that can be heard during inspiration or expiration and produced by air flowing through airways containing secretions. Caused by secretions in the large main stem that clear or improve with coughing
Fine Crackles Late inspiratory crackles that are heard over the lung periphery. Causes by atelectasis, alveoli ad smaller airways opening.
Wheezing High pitched, musical quality heard on inspiration and/or expiration. Caused by produced air flowing through constricted airways (asthma, bronchitis). If unilateral, foreign body aspiration should be suspected.
Stridor High pitched inspiratory sound heard in the upper airway. Caused by supraglottic swelling (epiglottitis), subglottic swelling (croup or post extubation), and foreign body aspiration. Sign of something life threatening.
Pleural Friction Rub A course, grating, raspy or crunching sound heard over lung periphery (sandpaper). Caused by inflamed surface of the visceral and parietal pleura rubbing together. Has been associated with pleurisy, TB, and lung cancer.
Egophony Patient says "e" and it sounds like "a" Caused by consolidation of the lung tissue
Bronchophony (Whispered Pectoriloquy) Increased intensity or transmission of voice. Caused by consolidation of the lung tissue
