To know more or find more such videos please visit https://assimilate.in/ Acute Respiratory Distress Syndrome (ARDS) represents a stereotypical response to various etiologies. It progresses through several stages, beginning with alveolar-capillary damage, followed by a proliferative phase marked by improved lung function and healing, and finally a fibrotic phase signaling the end of the acute disease process. Focused changes on chest radiographs may be visible in patients with direct pulmonary insults. The initial radiograph in non-direct insults may be nonspecific or similar to congestive heart failure with mild effusions. Following that, interstitial pulmonary edema with diffuse infiltrates develops. As the disease progresses, the typical bilateral diffuse alveolar and reticular opacities appear. On a Computed Tomographic (CT) scan of the chest, the most prominent features of ARDS are diffuse consolidation with air bronchograms, bullae, pleural effusions, pneumomediastinum, and pneumothoraxes. Lung cysts of various sizes and numbers may appear later in the disease. A CT scan can detect ARDS complications as well as those related to catheter and tube placement, such as pneumothorax, pneumomediastinum, focal pneumonia, catheter malposition, and pulmonary infarction. Dr. Raymond Dominic Savio, discusses in detail about the pathophysiology and imaging in acute respiratory distress syndrome.
