100
Q

Difference between crackles associated with alveolar fluid vs interstitial lung disease .

A

Egophony

Crackles (or rales) are predominantly heard during inspiration and are considered a sign of alveolar or interstitial lung disease. A variety of diseases cause crackles including pneumonia, pulmonary edema, and any cause of interstitial lung fibrosis. Some clinicians attempt to distinguish between the “wet” crackles of pulmonary edema or pneumonia compared to the “dry” crackles of interstitial lung disease. However, this is not a reliable finding. A better way to differentiate between the alveolar and interstitial causes of crackles is to test for the presence of egophony. When alveolar filling is present, the “EEE” sound will be heard as a “AH” sound; however, in interstitial lung disease the “EEE” sound will be preserved. Whispered pectoriloquy will also be intensified in alveolar filling processes, but not interstitial lung disease.

The lack of breath sounds is important to note, but can be caused by many factors including severe bullous lung disease, emphysema, pneumothorax, or pleural effusion.

101
Q
