What are the findings indicative of tracheobronchial disruption?

The findings indicative of tracheobronchial disruption include subcutaneous emphysema and Hamman's Crunch due to the mechanism of injury and the nature of the resulting pathophysiological changes.

Subcutaneous emphysema occurs when air leaks from the tracheobronchial tree into the soft tissues of the neck and chest, often presenting as swelling and crepitus in these areas. This is a direct consequence of a breach in the airway structures which allows air to escape into surrounding tissues.

Hamman's Crunch is a classic sign that can be heard through a stethoscope and is characterized by a crunching sound that coincides with the heartbeat, akin to a "tooting" sound during respiration. This phenomenon is associated with the presence of air in the mediastinum, often resulting from significant trauma that compromises the integrity of the tracheobronchial system.

Collectively, these findings are critical in diagnosing tracheobronchial injuries, as they signal the presence of significant air leakage and potential airway compromise, necessitating prompt intervention. This makes them key indicators in the assessment of such injuries.
