Distinguishing Between a Hemothorax and a Pneumothorax Tension pneumothorax is a life-threatening condition that can occur with chest trauma when air is trapped in the pleural cavity leading to a cascading impact including a rapid deterioration of a patient's ability to maintain oxygenation. 21 (3):393-4. The rate of iatrogenic pneumothoraces is increasing in US hospitals as intensive care modalities have increasingly become dependent on positive pressure ventilation and central venous catheters. Diagnosis and management of traumatic and tension pneumothoraces require a high level of cooperation among interprofessional healthcare team members. 2000 Aug. 55 (8):666-71. Mediators Inflamm.

Close radiographic view of a small pneumothorax in a patient with idiopathic pulmonary fibrosis, following video-assisted thoracoscopic surgery (VATS) lung biopsy (same patient as in the previous image). There are two types of pleurodesis: mechanical and chemical. This places pressure on the lung and can lead to its collapse anda shift of the surrounding structures. However, these observations are neither sensitive nor specific for making the diagnosis of pneumothorax or ruling out the possibility of pneumothorax. Radiograph showing subcutaneous emphysema and pneumothorax. The initial assessment involves a chest radiograph (CXR) to confirm the diagnosis.[21]. Traumatic mediastinum, although present in up to 6% of patients, does not portend serious injury. Tracheal deviation is an inconsistent finding.

Pneumothoraces are classified as simple (no shift of mediastinal structures), tension (shift in mediastinal structures present), or open (air passing through an open chest wound). 2006 Sep. 28 (3):637-50. COPD can mimic the appearance of pneumothorax on thoracic ultrasound. O'Rourke JP, Yee ES. [QxMD MEDLINE Link]. If on mechanical ventilation, the airway pressure alarms are triggered.

Needle thoracostomy in the treatment of a tension pneumothorax in trauma patients: what size needle?. 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. Nevertheless, tension pneumothorax should always be a consideration when acute compromise occurs. Ultrasound findings includethe absence of lung sliding and the presence of a lung point. Affected patients may also reveal altered mental status changes, including decreased alertness and/or consciousness (a rare finding). [QxMD MEDLINE Link].
