Chronic bronchitis tends to affect men more often than women. While the primary risk factor for chronic bronchitis is smoking, there is still a 4–22% chance that non-smokers can get chronic bronchitis. This might suggest other risk factors such as the inhalation of fuels, dusts, fumes and genetic factor. [40]
Air trapping, also called gas trapping, is an abnormal retention of air in the lungs where it is difficult to exhale completely. [1] It is observed in obstructive lung diseases such as asthma , bronchiolitis obliterans syndrome and chronic obstructive pulmonary diseases such as emphysema and chronic bronchitis .
Bronchitis is another common infection that takes place in the lower respiratory tract. It is an inflammation of the bronchial tubes. There are two forms of this infection: acute bronchitis, which is treatable and can go away without treatment, or chronic bronchitis, which comes and goes, but will always affect one's lungs.
Any process that increases the CC by increasing the closing volume (CV) can increase an individual's risk of hypoxemia, as the small airways may collapse during exhalation, leading to air trapping and atelectasis. A mnemonic for factors increasing closing capacity is ACLS-S: Age, Chronic bronchitis, LV failure, Smoking, Surgery.
Bronchitis is defined as inflammation of the bronchi, which can either be acute or chronic. Acute bronchitis is usually caused by viral or bacterial infections. Many sufferers of chronic bronchitis also suffer from chronic obstructive pulmonary disease (COPD), and this is usually associated with smoking or long-term exposure to irritants.
Asthma, bronchiectasis, and chronic obstructive pulmonary disease (COPD) that includes chronic bronchitis, and emphysema, 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.
The percentage of children ages 2-4 diagnosed with a respiratory illness-bacteria grew from 1% to 7.2% between March 31 and Oct. 5, the CDC reported.
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction.Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.
