Tension pneumothorax

Last edited: 4/15/2026

Overview

Tension pneumothorax is a life-threatening condition characterized by the accumulation of air under pressure in the pleural space, leading to lung collapse and shifts in mediastinal structures, compromising cardiopulmonary function 2.

Diagnosis

  • Clinical signs include tracheal deviation, decreased breath sounds on the affected side, hyperresonance on percussion, and cyanosis 2.
  • Chest radiography essential for confirming pneumothorax and assessing severity 2.
  • Elevated intrathoracic pressure may be indicated by absent breath sounds and tracheal deviation 2.
  • Management

  • First-line treatment: Needle decompression in the second intercostal space or insertion of a large-bore chest tube in the midaxillary line 2.
  • Alternative device: Use of a new decompression device for effective prehospital and emergency department management, showing high efficacy with minimal complications 2.
  • Monitoring: Continuous monitoring for re-expansion of the lung and complications such as intercostal artery laceration 2.
  • Special Populations

  • No specific data provided in the abstracts regarding management in pregnancy, pediatrics, elderly, or patients with comorbidities 13.
  • Key Recommendations

  • Rapid decompression using needle aspiration or chest tube insertion is critical in managing tension pneumothorax (Evidence: Strong 2).
  • Consider new decompression devices for prehospital and emergency settings due to their effectiveness and ease of use (Evidence: Moderate 2).
  • Monitor for complications post-decompression, particularly focusing on lung re-expansion and potential iatrogenic injuries (Evidence: Expert opinion 2).
