Contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. [4] A collapsed lung can result when the pleural cavity (the space outside the lung) accumulates blood or air (pneumothorax) or both (hemopneumothorax). These ...
The Berlin Criteria specifies: [4] Timing: onset of respiratory symptoms within one week of an injury/insult. Chest Imaging: either chest x-ray or CT scan, must show bilateral opacities that cannot be fully explained by other conditions such as effusion, lung/lobar collapse, or lung nodules.
Very rarely, both lungs may be affected by a pneumothorax. [6] It is often called a "collapsed lung", although that term may also refer to atelectasis. [1] A primary spontaneous pneumothorax is one that occurs without an apparent cause and in the absence of significant lung disease. [3]
Symptoms of pneumonia in the elderly may vary depending on the type of pneumonia and the overall health of the person. While not all of these may be present, the symptoms of pneumonia in seniors ...

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.
lung injury of acute onset, within 1 week of an apparent clinical insult and with the progression of respiratory symptoms; bilateral opacities on chest imaging (chest radiograph or CT) not explained by other lung pathology (e.g. effusion, lobar/lung collapse, or nodules) respiratory failure not explained by heart failure or volume overload ...
The flail segment moves in the opposite direction to the rest of the chest wall: because of the ambient pressure in comparison to the pressure inside the lungs, it goes in while the rest of the chest is moving out, and vice versa. This so-called "paradoxical breathing" [4] is painful and increases the work involved in breathing.
