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]
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 ...
Complications Pneumothorax Flail chest is a life-threatening medical condition that occurs when a segment of the rib cage breaks due to trauma and becomes detached from the rest of the chest wall .
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 .
Major complications are pneumothorax (3–30%), hemopneumothorax, hemorrhage, hypotension (low blood pressure due to a vasovagal response) and reexpansion pulmonary edema. Minor complications include a dry tap (no fluid return), subcutaneous hematoma or seroma, anxiety, dyspnea and cough (after removing large volume of fluid).
Most people with TBI who die do so within minutes of the injury, due to complications such as pneumothorax and insufficient airway and to other injuries that occurred at the same time. [5] Most late deaths that occur in TBI are attributed to sepsis or multiple organ dysfunction syndrome (MODS). [2]
Left-sided tension pneumothorax. Note the area without lung markings which is air in the pleural space. Also note the tracheal and mediastinal shift from the patient's left to right. Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax.
Chest tube clogging can lead to retained blood around the heart and lungs that can contribute to complications and increase mortality. [11] A common complication after thoracic surgery that arises within 30–50% of patients are air leaks. If a chest tube clogs when there is an air leak the patient will develop a pneumothorax.
