2024年11月12日 · Treatment of a tension pneumothorax is an extreme medical emergency when a life can be saved or lost on the basis of correct recognition and rapid decompression.

2024年11月5日 · A tension pneumothorax occurs when there is progressive accumulation of gas within the pleural cavity. This is usually caused by a ball-valve effect with progressive increases in intrapleural air during each expiration.

2024年12月3日 · In tension pneumothorax a check-valve mechanism results in progressive enlargement of the pneumothorax which exerts pressure on the diaphragm and mediastinum, narrowing the superior vena cava and other blood vessels. Obstructed venous return may cause cardiovascular collapse and death.

Chest x-ray demonstrates a large left sided pneumothorax. The lung is almost completely collapsed, and there is shift of the mediastinum towards the right. 2 case questions available

2021年10月30日 · A pneumothorax is seen as a region of lucency (dark) around the edge of the lung. This is difficult to see because the lung itself is black too. They are more easily seen on erect chest x-rays as the free air typically rises up to the apex above the lung, making it …

This case demonstrates the common findings in tension pneumothorax: increased lucency on the side of the pneumothorax; lung edge; absence of lung markings peripherally; mediastinal shift away from the pneumothorax (indicating tension)

A left sided tension pneumothorax, arguably the patient should have never had this X-ray! Thankfully, he underwent needle aspiration immediately after this radiograph was taken and following this, insertion of intercostal chest drain.

COVID-19 patient crashed and required endotracheal intubation for mechanical ventilation. Rapidly developed tension pneumothorax, most likely due to barotrauma. A chest drain was inserted, with expansion of the right lung.

The control x-ray demonstrates the complete regression of the right sided pneumothorax and the signs of a tension mechanism. The chest tube is in an appropriate position, with a small amount of subcutaneous emphysema that developed in the soft tissues adjacent to its insertion point.

A small percentage of pneumothoraces are under tension. These are truly life threatening and merits urgent medical intervention. 2 articles feature images from this case
