Sonographic detection of pneumothorax by radiology residents as part of extended focused assessment with sonography for trauma. The incidence of traumatic pneumothorax depends on the size and mechanism of the injury. Pneumothorax can result in tension physiology as well though the hemodynamic compromise from this, when a patient is on mechanical ventilation, is usually quicker than with hemothorax. 1993.

This leads to lung collapse. If on mechanical ventilation, the airway pressure alarms are triggered. Common findings include chest tenderness, ecchymoses, and respiratory distress; hypotension or shock may be present. Pneumothorax is when air collects in between the parietal and viscera pleurae resulting in lung collapse.

It is difficult to determine the actual incidence of tension pneumothorax as by the time trauma patients are transported to trauma centers, they have already received decompressive needle thoracotomies. Symptoms typically include sudden onset of sharp, one-sided chest pain and shortness of breath. Jalota Sahota R, Sayad E. Tension Pneumothorax. [QxMD MEDLINE Link].

[9][10][14][11][15], Before understanding the pathophysiology of tension pneumothorax, it is essential to understand normal lung physiology. The patient was taken immediately to the operating room, where a large rupture of the esophagus was repaired. The initial assessment involves a chest radiograph (CXR) to confirm the diagnosis.[21]. Computed tomography scan demonstrating secondary spontaneous pneumothorax (SSP) from radiation/chemotherapy for lymphoma. Iatrogenic pneumothorax is a traumatic pneumothorax that results from injury to the pleura, with air introduced into the pleural cavity secondary to a diagnostic or therapeutic medical intervention.

Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. This chest radiograph has 2 abnormalities: (1) tension pneumothorax and (2) potentially life-saving intervention delayed while waiting for x-ray results. In the case of trauma, this usually happens outside the hospital or in the emergency department (ED). Findings may be affected by the volume status of the patient.

Central venous catheterization increases the risk of pneumothoraces when placed in the internal jugular or subclavian. 2004 Oct. 128 (4):502-8. If a chest tube is malpositioning or becomes plugged, it can cease to function, and the pneumothorax can recur. Cardiac arrest associated with asystole or pulseless electrical activity (PEA) may ultimately result. J Emerg Med. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. A tension pneumothorax is caused by excessive pressure build up around the lung due to a breach in the lung surface which will admit air into the pleural cavity during inspiration but will not allow any air to escape during expiration.
