Marked depression of the right hemidiaphragm is noted, and mediastinal shift is to the left side, suggestive of tension pneumothorax. Tension pneumothorax is more likely to occur with trauma involving an opening in the chest wall. Tension pneumothorax most commonly occurs in patients receiving positive-pressure ventilation (with mechanical ventilation or particularly during resuscitation). [QxMD MEDLINE Link].

This chest radiograph shows pneumomediastinum (radiolucency noted around the left heart border) in this patient who had a respiratory and circulatory arrest in the emergency department after experiencing multiple episodes of vomiting and a rigid abdomen. Thus, having personnel trained in emergency assessment of pneumothoraces and having an emergency kit for thoracotomies, intubation, and patient stabilization is essential. [37][38], Ventilator-related tension pneumothorax has been found to have dire outcomes and result in death more frequently. Chest. Civilian spontaneous pneumothorax. 47 (5):415-8. How emergency physicians choose chest tube size for traumatic pneumothorax or hemothorax: a comparison between 28Fr and smaller tube. Pneumothorax is when air collects in between the parietal and viscera pleurae resulting in lung collapse. Numerous techniques exist, and the literature is replete with opinions, but in the first instance relieving the tension, even if not draining the pneumothorax, is life-saving. Sometimes, reliance on history alone may be warranted. Clinical signs of a tension pneumothorax in the ventilated patient are comparably rapid, with arterial and mixed venous peripheral capillary oxygen saturation immediately decreasing 5. Chen JS, Hsu HH, Huang PM, Kuo SW, Lin MW, Chang CC, et al. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Blunt thoracic trauma patiens may have tracheal deviation and deformities of the chest wall may be observed. If a chest tube is malpositioning or becomes plugged, it can cease to function, and the pneumothorax can recur. Presentation is variable and may initially have no symptoms. 5 (3):181-2.

The development of tension pneumothorax in patients who are ventilated will generally be of faster onset with immediate, progressive arterial and mixed venous oxyhemoglobin saturation decline and immediate decline in cardiac output. Advantages of Cardiopulmonary Ultrasound in PostCardiopulmonary Resuscitation Tension Pneumothorax. General Thoracic Surgery. By definition, spontaneous pneumothorax is not associated with trauma or stress. For a general discussion, refer to the pneumothoraxarticle. Duringinspiration, a sizeable high-pressure air collection accumulates in the intrapleural space and is not able to completely exit during expiration. 3. Am Rev Respir Dis. On volume-control ventilation, this is indicated by marked increase in both peak and plateau pressures, with relatively preserved peak and plateau pressure difference. In this situation, the ipsilateral lung will, if normal, collapse completely (although a less than normally compliant lung may remain partially inflated). 1993 Dec. 43 (12):709-22. It is most commonly encountered in the prehospital, emergency department, and intensivetherapyunit (ITU) settings. [QxMD MEDLINE Link]. In cases of tension pneumothorax, immediate decompression is a priority and should not be delayed by imaging. If the patient is stable, then diagnostic imaging (i.e., CXR) can be done prior to treatment. AJR Am J Roentgenol. Mil Med. The timely and accurate evaluation leadsto early interventions decreasing mortality and morbidity. CXR can demonstrate one or more of the following: A chest computed tomography can be done if the diagnosis is unclear on the X-ray. This is a life-threatening emergency that needs urgent management. (2018) Journal of Ultrasound in Medicine. While this is a commonly considered cause of shock in obvious trauma, it can also occur non-traumatically in ventilated patients, or in the setting of occult trauma. 2006 Sep. 28 (3):637-50.

The first-line responders when a patient develops a traumatic or tension pneumothorax vary depending on the situation and underlying etiology.

Signs and symptoms of tension pneumothorax are usually more impressive than those seen with a simple pneumothorax, and clinical interpretation of these is crucial for diagnosing and treating the condition. Needle decompression is done at the second intercostal space in the midclavicular line above the rib with an angio-catheter. 31 (2): 242-4. Zehtabchi S, Rios CL. Kazerooni EA, Gross BH.

In a recent study, 95% of pneumothorax episodes were observed to be iatrogenic; of these, barotrauma secondary to mechanical ventilation resulted in 69.6% of cases, 41.1% of which were tension pneumothoraces. [QxMD MEDLINE Link]. Pleural cavity (or intrapleural) pressure is negative as compared to lung pressure and atmospheric pressure. Severe acute respiratory syndrome complicated by spontaneous pneumothorax. If multiple rib fractures occur along the midlateral (red arrows) or anterior chest wall (blue arrows), a flail chest (dotted black lines) may result, which may result in pneumothorax.

Depending on the depth of a penetrating chest wound, the air will flow into the pleural space either through the chest wall or from the visceral pleura of the tracheobronchial tree. 29 (3):239-42. The most common underlying abnormality in secondary spontaneous pneumothorax is chronic obstructive pulmonary disease (COPD), and cystic fibrosis carries one of the highest associations, with more than 20% reporting spontaneous pneumothorax.
