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.
Most commonly emphysema refers to the permanent enlargement of air spaces in the lungs, [5] [6] and is also known as pulmonary emphysema. Emphysema is a lower respiratory tract disease, [ 7 ] characterised by enlarged air-filled spaces in the lungs , that can vary in size and may be very large.
In children, hemoptysis is commonly caused by the presence of a foreign body in the airway. Other common causes include lung cancers and tuberculosis. Less common causes include aspergilloma, bronchiectasis, coccidioidomycosis, pulmonary embolism, pneumonic plague, and cystic fibrosis.
Bronchiectasis without CF is known as non-CF bronchiectasis. Historically, about half of all case of non-CF bronchiectasis were found to be idiopathic , or without a known cause. [ 25 ] However, more recent studies with a more thorough diagnostic work-up have found an etiology in 60 to 90% of patients.
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 or exacerbations) due to abnormalities of the airways (bronchitis ...
For children younger than 15 years old, nasopharyngel catheters or nasal prongs are recommended over a face mask or head box. [26] A Cochrane review in 2014 presented a summary to identify children complaining of severe LRTI, however; further research is required to determine the effectiveness of supplemental oxygen and the best delivery method.
Pfizer's vaccine reduced the risk of symptomatic infection by 80% in children between 6 months and 4 years of age. Moderna's vaccine had an efficacy of 37% in kids 2 to 5 years old, and 51% in ...
When chronic bronchitis occurs together with decreased airflow it is known as chronic obstructive pulmonary disease (COPD). [27] [26] Many people with chronic bronchitis have COPD; however, most people with COPD do not also have chronic bronchitis. [10] [28] Estimates of the number of people with COPD who have chronic bronchitis are 7–40%.
