A tension pneumothorax is accumulation of air in the pleural cavity under pressure, compressing the lungs and decreases venous return to the heart.

A tension pneumothorax when a lung or chest wall is breached, so that air can penetrate into the pleural space, but not out of it (a one-way valve) develops. As a result, collects air and compresses the lungs and finally shifts the mediastinum, compressing the contralateral lung and increases the intrathoracic pressure enough to reduce the venous return to the heart, triggering a shock. These effects may develop quickly, especially in patients with positive pressure ventilation.

These effects may develop quickly, especially in patients with positive pressure ventilation. Causes include mechanical ventilation (mostly) and simple (uncomplicated) pneumothorax with lung injury, which following penetrating or blunt chest trauma can not be closed or central venous cannulation. Symptoms and signs The symptoms are similar to those at the beginning of a simple pneumothorax (pneumothorax). With increase in intrathoracic pressure, patients develop hypotension, Trachealabweichungen and expansion of the jugular vein. The affected hemithorax is hyperresonant in percussion and often feels somewhat distended, tense and poorly compressible upon palpation of. Diagnosis Clinical Investigation A tension pneumothorax should be diagnosed by clinical findings. Therapy should not be up to confirm serviced by the outstanding exposure. Although a cardiac tamponade may also cause hypotension, expansion of the jugular vein and sometimes shortness of breath, a tension pneumothorax can be clinically distinguished by its unilateral missing Atemung and hyperresonance at percussion. Tips and Risks A tension pneumothorax should be diagnosed and bedside based on clinical findings are immediately treated with Nadeldekompression and / or tube chest tube. Therapy Nadeldekompression and subsequent pleural drainage. The treatment consists in an immediate Nadeldekompression by inserting a large lumen cannula (z. B. 14 or 16 gauge) in the second intercostal space in the midclavicular line is usually emit air. Since Nadeldekompression causes a simple pneumothorax, a chest tube should be carried out immediately afterwards.
