Diagnosis of obstructive disease requires several factors depending on the exact disease being diagnosed. However one commonality between them is an FEV1/FVC ratio less than 0.7, i.e. the inability to exhale 70% of their breath within one second. [11] Following is an overview of the main obstructive lung diseases.
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.
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 2012, respiratory conditions were the most frequent reasons for hospital stays among children. [31] In the UK, approximately 1 in 7 individuals are affected by some form of chronic lung disease, most commonly chronic obstructive pulmonary disease, which includes asthma, chronic bronchitis and emphysema. [32]
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
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 ...
