In spontaneous pneumomediastinum, the patient appears normal. Patient with pneumomediastinum secondary to an exacerbation of asthma may appear distressed. On physical examination, the most pathognomic sign of pneumomediastinum is Hamman's sign, which is mediastinal crunch or click present on auscultation over the cardiac apex and the left sternal border synchronous with the heartbeat. Subcutaneous emphysema can also be detected in a patient with pneumomediastinum.

Overview

In spontaneous pneumomediastinum, the patient appears normal. Patient with pneumomediastinum secondary to an exacerbation of asthma may appear distressed. On physical examination, the most pathognomic sign of pneumomediastinum is Hamman's sign, which is mediastinal crunch or click present on auscultation over the cardiac apex and the left sternal border synchronous with the heartbeat. Subcutaneous emphysema can also be detected in a patient with pneumomediastinum.

Physical Examination

The patient may present with the physical finding of the primary condition causing pneumomediastinum or precipitating factors including, asthma, COPD, pneumonia, pneumothorax, Boerhaave syndrome, cystic fibrosis, mediastinitis, interstitial lung disease, or ARDS.[1][2][3][4][5]
