Emphysema is any air-filled enlargement in the body's tissues. [5] Most commonly emphysema refers to the permanent enlargement of air spaces (alveoli) 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 ...
Subcutaneous emphysema can result from puncture of parts of the respiratory or gastrointestinal systems. Particularly in the chest and neck, air may become trapped as a result of penetrating trauma (e.g., gunshot wounds or stab wounds) or blunt trauma. Infection (e.g., gas gangrene) can cause gas to be trapped in the subcutaneous tissues.
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 ...
Certain breathing strategies help people with COPD enjoy physical activity. These strategies, primarily pursed-lip breathing and diaphragmatic breathing, move air through their lungs more ...
Barrel chest due to chronic bronchitis and emphysema.. Barrel chest generally refers to a broad, deep chest found on a patient (or other person). A barrel chested person will usually have a naturally large ribcage, very round (i.e., vertically cylindrical) torso, large lung capacity, and can potentially have great upper body strength.
Pneumomediastinum (from Greek pneuma – "air", also known as mediastinal emphysema) [ 1 ] is pneumatosis (abnormal presence of air or other gas) in the mediastinum, the central part of the chest cavity. First described in 1819 by René Laennec, [ 2 ][ 3 ] the condition can result from physical trauma or other situations that lead to air ...
3 million per year [1] Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [1] For those who survive, a decreased quality of life is ...
Chronic respiratory diseases are long-term diseases of the airways and other structures of the lung. They are characterized by a high inflammatory cell recruitment (neutrophil) and/or destructive cycle of infection, (e.g. mediated by Pseudomonas aeruginosa). Some of the most common are asthma, chronic obstructive pulmonary disease, and acute ...
