Tracheobronchomalacia may also occur in people who have normal cartilaginous structure of the trachea, but significant atrophy of the posterior wall, causing significant invagination of the trachea on expiration. In these cases it is more commonly known as excessive dynamic airway collapse (EDAC).
Dynamic compression of the airways results when intrapleural pressure equals or exceeds alveolar pressure, which causes dynamic collapsing of the lung airways. It is termed dynamic given the transpulmonary pressure (alveolar pressure − intrapleural pressure) varies based on factors including lung volume, compliance, resistance, existing pathologies, etc. [1]
Bronchography provides an accurate measurement of the airway lumen with a dynamic and morphological evaluation of the tracheobronchial tree. However, this requires the injection of contrast material within the narrowed airway. Risks include allergic reaction, airway plugging, or complete airway obstruction. [5]
Dynamic Airways' former logo A Dynamic Airways Boeing 767-300ER at JFK Airport Terminal 1, in the former livery, registered N740JM. Dynamic Airways was established by Dynamic Aviation with its first aircraft being a second-hand McDonnell Douglas MD-88 delivered a year before operations started in 2009. [3]
Dynamic airway compression occurs when intrapleural pressure equals or exceeds alveolar pressure, which causes dynamic collapsing of the lung airways. It is termed dynamic given the transpulmonary pressure (alveolar pressure − intrapleural pressure) varies based on factors including lung volume, compliance, resistance, existing pathologies, etc. [6] It occurs during forced expiration when ...

When this becomes severe to the point of stupor or coma (defined as a score on the Glasgow Coma Scale of less than 8), [3] dynamic collapse of the extrinsic muscles of the airway can obstruct the airway, impeding the free flow of air into the lungs. Furthermore, protective airway reflexes such as coughing and swallowing may be diminished or ...
