pulm1 breath sounds
| Question | Answer |
|---|---|
| Normal tracheal and bronchial sounds | These are loud and tubular sounds with a high-pitch noted during inspiration and expiration, pausing between the two components. |
| Vesicular breath sounds | These are normal, soft, and low-pitched sounds heard over the more distal airways primarily during inspiration. During expiration the soft sound is diminished and only heard during the beginning of expiration. |
| Abnormal breath sounds | These are sounds that are heard outside of their normal location or phase of respiration. |
| Adventitous breath sounds | These are abnormal breath sounds heard using a stethoscope with inspiration and/or expiration. These sounds can be continuous or discontinuous sounds. |
| Wheeze | These are continuous adventitious breath sounds that are high-pitched and varying in duration. These are usually heard during expiration, but may also be present on inspiration. |
| Wheezes are typically a sign of | airway obstruction from retained secretions or due to bronchoconstriction or bronchospasm with quality similar to whistling. Wheezes found with inspiration occur with movement of air through secretions. |
| Rhonchi | These are continuous adventitious breath sounds that are low-pitched and occur with both inspiration and expiration. Rhonchi are associated with an obstructive process of the larger or more central airways with quality similar to snoring. |
| Stridor | continuous adventitious sound, very high-pitched wheeze that can be heard with inspiration and expiration also indicates upper airway obstruction. stridor that is heard without a stethoscope is an emergency. |
| Crackle (formerly rales) | A discontinuous adventitious sound heard with a stethoscope that “bubbles” or “pops.” Crackles typically represent the movement of fluid or secretions during inspiration (wet crackles) or occur from the sudden opening of closed airways (dry crackles). |
| Crackle (formerly rales) | if they are during the latter half of inspiration they represent atelectasis, fibrosis, pulmonary edema or pleural effusion. Crackles secondary to the movement of secretions are usually low-pitched and can be heard during inspiration and/or expiration. |
| Bronchial breath sounds | These sounds are abnormal breath sounds when heard in locations that vesicular sounds are normally present. Pneumonia may produce these sounds. |
| Decreased or diminished sounds | A less audible sound may indicate severe congestion, emphysema or hypoventilation. |
| Absent breath sounds | may indicate pneumothorax or lung collapse. |
