In contrast, tension pneumothorax is a medical emergency and may be treated before imaging – especially if there is severe hypoxia, very low blood pressure, or an impaired level of consciousness. In tension pneumothorax, X-rays are sometimes required if there is doubt about the anatomical location of the pneumothorax. [16] [18]
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
An easy to understand example is a traumatic pneumothorax, where air enters the pleural space from outside the body, as occurs with puncture to the chest wall. Similarly, scuba divers ascending while holding their breath with their lungs fully inflated can cause air sacs ( alveoli ) to burst and leak high pressure air into the pleural space.
Potential complications include a pneumothorax, pulmonary contusion, and pneumonia. [2] [1] Rib fractures usually occur from a direct blow to the chest such as during a motor vehicle collision or from a crush injury. [2] [1] Coughing or metastatic cancer may also result in a broken rib. [1] The middle ribs are most commonly fractured.
Lung procedures, like surgery, drainage of fluid with a needle, examination of the lung from the inside with a light and a camera, or mechanical ventilation, also can cause a pneumothorax. The most common symptom is sudden pain in one side of the lung and shortness of breath. A pneumothorax also can put pressure on the lung and cause it to ...
Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...

The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
