Tracheobronchomalacia and excessive dynamic airway collapse
Tracheobronchomalacia and excessive dynamic airway collapse MURGU SD, COLT HG. Respirology 2006; 11: 388–406 Abstract: Tracheobronchomalacia and excessive dynamic airway collapse are two separate forms of dynamic central airway obstruction that may or may not coexist. These entities are increasingly recognized as asthma and COPD imitators. The understanding of these disease processes, however, ...
متن کاملTracheobronchomalacia and/or Excessive Dynamic Airway Collapse?
Expiratory airway collapse is defined as more than 50% reduction of the horizontal cross-sectional area at expiration or during coughing and is due to pure tracheobronchomalacia (TBM) or excessive dynamic airway collapse (EDAC) (1). It is not easy to make a clear differentiation between TBM and EDAC. These two conditions are different entities, yet they may be mistaken for each other and they m...
متن کاملTracheobronchomalacia and Excessive Dynamic Airway Collapse.
Tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) are more frequently being recognized as the etiology of multiple types of respiratory complaints from chronic cough to exertional syncope to recurrent infections. Identification of these conditions requires a high suspicion, as well as a thorough history and physical examination. Dynamic computed tomography imaging and bro...
متن کاملUpper Airway Obstruction*
Chronic upper airway obstruction is frequently unrecognized or misdiagnosed as other conditions such as asthma or chronic airflow obstruction (CAO). Clinical features such as stridor may lead to diagnosis or it may initially be suspected from the results of pulmonary function tests (PFTs) ordered for another reason. We will review the physiology and the pulmonary function tests which are necess...
متن کاملEmergency use of the laryngeal mask airway in severe upper airway obstruction caused by supraglottic oedema.
We report two cases of severe upper airway obstruction caused by supraglottic oedema which developed rapidly at the time of anaesthesia. Conventional methods to relieve the obstruction failed and it was only overcome when a laryngeal mask airway (LMA) was inserted and positive pressure applied manually during inspiration. In one case a fibrescope was passed via the LMA and this revealed two cus...
