Atelectasis of the right lower lobe seen on chest X-ray. Clinically significant atelectasis is generally visible on chest X-ray; findings can include lung opacification and/or loss of lung volume. Post-surgical atelectasis will be bibasal in pattern. Chest CT or bronchoscopy may be necessary if the cause of atelectasis is not clinically ...
Generally, the right middle and lower lung lobes are the most common sites affected, due to the larger caliber and more vertical orientation of the right mainstem bronchus. People who aspirate while standing can have bilateral lower lung lobe infiltrates.
In adults, the right lower lobe of the lung is the most common site of recurrent pneumonia in foreign body aspiration. [2] This is due to the fact that the anatomy of the right main bronchus is wider and steeper than that of the left main bronchus, allowing objects to enter more easily than the left side. [2]
Chest x-ray demonstrating severe atelectasis or collapse of the right lung and mediastinal shift towards the right. Atelectasis is the partial collapse of a lung that is reversible. There are numerous etiologies, including post-operative atelectasis, surfactant deficiency, mucus plugging, and foreign body aspiration.
[15] [31] [61] In 1941, the surgeons Tyson and Crandall introduced pleural abrasion for the treatment of pneumothorax. [15] [62] Prior to the advent of anti-tuberculous medications, pneumothoraces were intentionally caused by healthcare providers in people with tuberculosis in an effort to collapse a lobe, or entire lung, around a cavitating ...
A chest X-ray showing right sided (seen on the left of the picture) pulmonary contusion associated with rib fractures and subcutaneous emphysema. Chest X-ray is the most common method used for diagnosis, [37] and may be used to confirm a diagnosis already made using clinical signs. [20] Consolidated areas appear white on an X-ray film. [42]
Crackles are caused by the "popping open" of small airways and alveoli collapsed by fluid, exudate, or lack of aeration during expiration. Crackles can be heard in people who have pneumonia , atelectasis , pulmonary fibrosis , acute bronchitis , bronchiectasis , acute respiratory distress syndrome (ARDS), interstitial lung disease or post ...
Polymicrobial lung abscesses are usually due to aspiration and are located in the posterior segments of the upper lobes or superior segments of the lower lobes. [2] Klebsiella pneumoniae is a common cause of lung abscesses and is usually monomicrobial (caused by a single species of bacteria).
