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]
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.
Bronchorrhea is the production of more than 100 mL per day of watery sputum. [1] Chronic bronchitis is a common cause, but it may also be caused by asthma, [2] pulmonary contusion, [3] bronchiectasis, tuberculosis, cancer, scorpion stings, severe hypothermia and poisoning by organophosphates and other poisons.
Chronic bronchitis is on a spectrum of smoking-related lung disease also known as chronic obstructive pulmonary disease (COPD). Other lung diseases on the spectrum such as emphysema can co-exist with COPD. It accounts for 5% of chronic cough. [16] Chemical irritants, such as cigarette smoke, are a common factor that can lead to chronic cough ...
Additionally, bronchitis is described as either acute or chronic depending on its presentation and is also further described by the causative agent. Acute bronchitis can be defined as acute bacterial or viral infection of the larger airways in healthy patients with no history of recurrent disease. [8]
This can be measured with breathing devices such as a peak flow meter or by spirometry. Most people with COPD have characteristics of emphysema and chronic bronchitis to varying degrees. Asthma being a reversible obstruction of airways is often considered separately, but many COPD patients also have some degree of reversibility in their airways ...
The College Football Playoff bracket is finally set and Caroline Fenton, Jason Fitz & Adam Breneman react to the final rankings and share what things the committee got right and which were wrong.
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production and/or exacerbations) due to abnormalities of the airways (bronchitis ...
