Barrios C, Tran T, Malinoski D, Lekawa M, Dolich M, Lush S, et al. 2006 Jan. 72 (1):31-4. In severe cases, the increased pressure can alsocompress the heart, the contralateral lung, and the vasculature leading to hemodynamic instability and cardiac arrest in some cases. Chest. 21 (3):393-4. On lung auscultation, decreased or absent breath sounds on the ipsilateral side, reduced tactile fremitus, hyper-resonant percussion sounds, and possible asymmetrical lung expansion are suggestive of pneumothorax. Check for errors and try again. [1][2]It is a severe condition that results when air is trapped in the pleural space under positive pressure, displacing mediastinal structures and compromising cardiopulmonary function.

This chest radiograph has 2 abnormalities: (1) tension pneumothorax and (2) potentially life-saving intervention delayed while waiting for x-ray results. Worsening pneumothorax Positive-pressure ventilation can lead to increased air in the chest cavity without a route of escape, worsening a pneumothorax and possibly leading to a tension pneumothorax. With blunt force trauma, a pneumothorax can occur if a rib fracture or dislocation lacerates the visceral pleura. Zengerink I, Brink PR, Laupland KB, Raber EL, Zygun D, Kortbeek JB. 2006. Pneumothorax, especially tension pneumothorax is fatal; complications that can occur due to pneumothorax and tube thoracostomy are: Diagnosing and managing traumatic and iatrogenic pneumothoraces require multidisciplinary coordination and teamwork. O'Rourke JP, Yee ES. It results in the re-expansion of the collapsed lung. Radiograph depicting a right-sided iatrogenic pneumothorax after transbronchial biopsy.
