Reactive airway disease (RAD) is an informal label that physicians apply to patients with symptoms similar to those of asthma. [1] An exact definition of the condition does not exist. [ 1 ] [ 2 ] Individuals who are typically labeled as having RAD generally have a history of wheezing, coughing, dyspnea , and production of sputum that may or may ...
Bronchial hyperresponsiveness is a hallmark of asthma but also occurs frequently in people with chronic obstructive pulmonary disease (COPD). [2] In the Lung Health Study, bronchial hyperresponsiveness was present in approximately two-thirds of patients with non-severe COPD, and this predicted lung function decline independently of other ...
Unlike those with sensitizer-induced occupational asthma, subjects with irritant-induced occupational asthma do not develop work-related asthma symptoms after re-exposure to low concentrations of the irritant that initiated the symptoms. [2] Reactive airways dysfunction syndrome (RADS) is a severe form of irritant induced asthma where ...
Airway remodelling, or airway remodeling, is a potential complication of certain endotypes (subtypes) of asthma. It is the sum of changes that occur in the airways of some asthmatic people compared to people without the disease.
Exercise-induced bronchoconstriction can be difficult to diagnose clinically given the lack of specific symptoms [2] and frequent misinterpretation as manifestations of vigorous exercise. There are many mimics that present with similar symptoms, such as vocal cord dysfunction, cardiac arrhythmias, cardiomyopathies, and gastroesophageal reflux ...
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...
If a clinician is concerned that reactive airway disease or asthma may be a component of the illness, a bronchodilator may be administered. [9] Anticholinergic inhalers, such as ipratropium bromide, have a modest short-term effect at best and are not recommended for treatment. [20] [50] [51]
Asthma, chronic bronchitis, bronchiectasis and chronic obstructive pulmonary disease (COPD) are all obstructive lung diseases characterised by airway obstruction. This limits the amount of air that is able to enter alveoli because of constriction of the bronchial tree, due to inflammation.
