Centrilobular emphysema, also called centriacinar emphysema, affects the centre of a pulmonary lobule (centrilobular) in the lung, the area around the terminal bronchiole and the first respiratory bronchiole, and can be seen on imaging as an area around the tip of the visible pulmonary artery.
Pulmonary interstitial emphysema is the condition of air escaping overdistended alveoli into the pulmonary interstitium. It is a rare disease that occurs most often in premature infants, even though it is possible to appear in adults. [25] It often presents as a slow deterioration with the need for increased ventilatory support.
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.
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 or exacerbations) due to abnormalities of the airways (bronchitis ...
3D still image of constricted airways as in bronchial asthma Lung tissue affected by emphysema using H&E stain. 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 ...
For optimal management of a pneumonia patient, the following must be assessed: pneumonia severity (including treatment location, e.g., home, hospital or intensive care), identification of causative organism, analgesia of chest pain, the need for supplemental oxygen, physiotherapy, hydration, bronchodilators and possible complications of ...
