Abstract Morbid obesity may influence several aspects of airway function. However, the effect of morbid obesity on expiratory tracheal collapse in COPD patients is unknown. We thus prospectively studied 100 COPD patients who underwent full pulmonary function tests (PFTs), 6-minute walk test (6MWT), Saint George's Respiratory Questionnaire (SGRQ), and low-dose CT at total lung capacity and during dynamic exhalation with spirometric monitoring. We examined correlations between percentage dynamic… 

Association Between Expiratory Central Airway Collapse and Respiratory Outcomes Among Smokers.

In a cross-sectional analysis of current and former smokers, the presence of ECAC was associated with worse respiratory quality of life and further studies are needed to assess long-term associations with clinical outcomes.

Paratracheal Paraseptal Emphysema and Expiratory Central Airway Collapse in Smokers

Paratracheal paraseptal emphysema adjacent to the trachea is associated with expiratory central airway collapse, and the identification of this risk factor on inspiratory scans should prompt further evaluation for expiratories centralAirway collapse.

Is intrathoracic tracheal collapsibility correlated to clinical phenotypes and sex in patients with COPD?

Intrathoracic tracheal collapsibility was directly correlated with inspiratory–expiratory volume variation at CT and with forced expiratory volume, and inversely correlated with reduced CT lung density and functional residual capacity, and was not correlated with cough and wheezing.

The case of a 62-year-old woman status post tracheostomy with persistent dyspnea in the supine position is presented and evidence of a previously unidentified pathophysiology: excessive dynamic airway collapse (EDAC) of the lower airway is demonstrated.

Expiratory reactance abnormalities in patients with expiratory dynamic airway collapse: a new application of impulse oscillometry

Data show a new utility of IOS: detecting EDAC in patients with normal lung function, which can be “silent” on breathing tests, but impulse oscillometry can reveal it.

Our Experience on Silicone Y-Stent for Severe COPD Complicated With Expiratory Central Airway Collapse

A study showed significant decrease in mMRC score with stenting for ECAC in severe COPD, and for 2 patients, the authors experienced severe complications during short-term follow-up period after stenting.

Excessive Dynamic Airway Collapse: An Unexpected Contributor to Respiratory Failure in a Surgical Patient

A 43-year-old morbidly obese patient who failed repeated attempts at extubation after elective hysterectomy is described, to discuss the processes of EDAC and TM, describe how this condition contributed to this patient's respiratory failure, and review diagnosis and management options.

Lung Parenchymal and Tracheal CT Morphology: Evaluation before and after Bariatric Surgery.

Dyspnea improved in obese participants after weight reduction, which correlated with less tracheal collapse and air trapping at end-expiration chest CT.

Semiquantitative Chest Computed Tomography Assessment Identifies Expiratory Central Airway Collapse in Symptomatic Military Personnel Deployed to Iraq and Afghanistan

A standardized semiquantitative approach to CT-based assessment of ECAC should improve reliable diagnosis in dyspneic patients and suggest that ECAC is common in symptomatic southwest Asia deployers.



Dynamic expiratory tracheal collapse in COPD: correlation with clinical and physiologic parameters.

Excessive expiratory tracheal collapse is observed in a subset of patients with COPD, but the magnitude of collapse is independent of disease severity and does not correlate significantly with physiologic parameters.

Age and sex dependence of forced expiratory central airway collapse in healthy volunteers.

The influence of age and sex on forced expiratory tracheal collapse should be considered in the diagnostic evaluation of expiratories dynamic airway collapse and/or tracheomalacia.

Respiratory restriction and elevated pleural and esophageal pressures in morbid obesity.

It is concluded that many severely obese supine subjects at relaxation volume have positive P(pl) throughout the chest, which suggests high P(Pl) in such individuals.

Tracheobronchomalacia: comparison between end-expiratory and dynamic expiratory CT for evaluation of central airway collapse.

PURPOSE To compare dynamic expiratory and end-expiratory computed tomography (CT) for depicting central airway collapse in patients with acquired tracheobronchomalacia (TBM). MATERIALS AND METHODS

Obesity and the lung: 5 · Obesity and COPD

It is proposed that, in patients with COPD, reduced oxidative capacity and systemic hypoxia may amplify these disturbances, not only in obese patients but also in subjects with hidden loss of fat-free mass.

The relation of body mass index to asthma, chronic bronchitis, and emphysema.

Patients with emphysema are more likely to be underweight, and patients with CB are morelikely to be obese, however, the temporal relationship between abnormal BMI and the onset of COPD is uncertain.

Tracheal collapsibility in healthy volunteers during forced expiration: assessment with multidetector CT.

Healthy volunteers demonstrate a wide range of forced expiratory tracheal collapse, frequently exceeding the current diagnostic criterion for tracheomalacia.

The metabolic syndrome in patients with chronic bronchitis and COPD: frequency and associated consequences for systemic inflammation and physical inactivity.

Almost one-half of the patients with CB/COPD had coexisting metabolic syndrome, with a slightly lower frequency in patients with severe COPD, which is associated with an increase in the levels of some systemic inflammatory markers and physical inactivity, independent of lung function impairment.

Tracheobronchoplasty for severe tracheobronchomalacia: a prospective outcome analysis.

In experienced hands, surgical central airway stabilization with posterior tracheobronchial splinting using a polypropylene mesh improves respiratory symptoms, health-related quality of life, and functional status in highly selected patients with severe symptomatic TBM.

Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary.

It is recommended that spirometry is required for the clinical diagnosis of COPD to avoid misdiagnosis and to ensure proper evaluation of severity of airflow limitation.
