Small airways disease results in gas trapping and may be seen as areas of low attenuation distal to the site of obstruction. Mosaic attenuation reflects localised areas of gas trapping and suggests heterogeneous distribution of airways disease. It may be seen in both asthma (141) and COPD (142).Oct 17, 2014
What causes small airway disease?, Small airway disease associated with exposure to a specific mineral dust—as from asbestos, aluminum oxide, iron oxide, silicates, or coal—is referred to as pneumoconiosis-associated small airway disease.
Furthermore, Is small airway disease the same as asthma?, Small airway dysfunction increases the risk of uncontrolled disease and predicts increased risk of asthma exacerbations, and is associated with important clinical entities such as nocturnal asthma and asthma related to exercise-induced signs and symptoms.
Finally, What is considered small airway disease?, Small airways disease comprise of a group infectious as well as non-infectious conditions that affect the small airways (i.e. airways that are more peripheral to the main bronchi and proximal bronchioles (4th the 14th generation) – arbitrarily considered to be those with an internal diameter of ≤2 mm 3).
Frequently Asked Question:
Is small airway disease curable?
Currently, there is no cure for or way to reverse COPD. Lifestyle changes, like quitting smoking, and treatment with bronchodilators and inhaled steroids can help expand airways and reduce inflammation. Surgery to remove damaged lung tissue and lung transplantation are options for some patients with severe disease.
Is small airway disease reversible?
Background. Asthma is a common, heterogeneous disorder characterized as a chronic inflammatory disease of the airways with bronchial hyperresponsiveness to a variety of stimuli, and variable airflow limitation that is often reversible either spontaneously or as a result of therapy [1].
What is considered small airway disease?
Small airways disease comprise of a group infectious as well as non-infectious conditions that affect the small airways (i.e. airways that are more peripheral to the main bronchi and proximal bronchioles (4th the 14th generation) – arbitrarily considered to be those with an internal diameter of ≤2 mm 3).
Is small airway disease Asthma?
Small airway dysfunction increases the risk of uncontrolled disease and predicts increased risk of asthma exacerbations, and is associated with important clinical entities such as nocturnal asthma and asthma related to exercise-induced signs and symptoms.
Is small airway disease serious?
Whilst death from small–airway disease is usually due to right-sided heart failure, obstructive respiratory failure and bronchopneumonia also contribute.
Is asthma a small airway disease?
The small airways of the lungs are commonly affected in pediatric and adult asthma. Small airways disease has been related to asthma control, severity, and risk of exacerbation. Diagnosis of small airways disease can be best made through evaluation of surgical lung specimens.
Is small airway disease the same as COPD?
Small airway disease (SAD) is a recognized feature of COPD9,10,11 and has been characterized by pathology, imaging, and physiological studies. The small airways are <2 mm diameter, and there is a dramatic increase in small airway resistance in COPD patients compared to controls12. This article focuses on SAD in COPD.
Is small airway disease curable?
Currently, there is no cure for or way to reverse COPD. Lifestyle changes, like quitting smoking, and treatment with bronchodilators and inhaled steroids can help expand airways and reduce inflammation. Surgery to remove damaged lung tissue and lung transplantation are options for some patients with severe disease.
Is small airway disease progressive?
The term “bronchiolitis obliterans” has been previously used for describing a wide range of histopathological lesions resulting in small airways lumen narrowing, and is still used for describing the clinical syndrome characterised by progressive and poorly reversible airflow limitation under some circumstances (e.g. …

Is there a difference between asthma and reactive airway disease?
D. Sometimes the terms “reactive airway disease” and “asthma” are used interchangeably, but they are not the same thing. Often, the term “reactive airway disease” is used when asthma is suspected, but not yet confirmed. Reactive airway disease in children is a general term that doesn’t indicate a specific diagnosis.

What causes small airway obstruction?
The obstruction of small airways occurs through varied mechanisms, including mucus impaction, reduction in airway diameter from inflammatory infiltrates, smooth muscle hypertrophy, or airway wall thickening. Also, loss of structural airway supports may enhance collapsibility of airways.
