Atelectasis is the partial collapse or closure of a lung resulting in reduced or absence in gas exchange. It is usually unilateral, affecting part or all of one lung. [2] It is a condition where the alveoli are deflated down to little or no volume, as distinct from pulmonary consolidation, in which they are filled with liquid.
Atelectasis occurs when distending pressure of the alveolus is overcome by surface tension of fluid within the alveolus. Repeated atelectasis and re-inflation leads to atelectotrauma . Atelectotrauma , atelectrauma , cyclic atelectasis or repeated alveolar collapse and expansion ( RACE ) are medical terms for the damage caused to the lung by ...
Paracicatricial emphysema, also known as irregular emphysema, is seen next to areas of fibrosis (scarring) as large spaces. The scarring is most often a result of silicosis, granulomatous infection, tuberculosis, or pulmonary infarction. It can be difficult to differentiate from the honeycombing of pulmonary fibrosis. [29]
Pulmonary fibrosis creates scar tissue. The scarring is permanent once it has developed. [29] Slowing the progression and prevention depends on the underlying cause: Treatment options for idiopathic pulmonary fibrosis are very limited, since no current treatment has stopped the progression of the disease.
Fibrothorax is a medical condition characterised by severe scarring and fusion of the layers of the pleural space surrounding the lungs resulting in decreased movement of the lung and ribcage. [1] The main symptom of fibrothorax is shortness of breath. There also may be recurrent fluid collections surrounding the lungs.
Peribronchial cuffing, also referred to as peribronchial thickening or bronchial wall thickening, is a radiologic sign which occurs when excess fluid or mucus buildup in the small airway passages of the lung causes localized patches of atelectasis (lung collapse). [1] This causes the area around the bronchus to appear more prominent on an X-ray ...
A group of state attorneys general on Thursday sued to halt Elon Musk's efforts to slash federal spending as head of President Donald Trump's new government efficiency agency, escalating the legal ...
Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate, abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
