During an arrest with suspected tension pneumothorax, what is the immediate management?

• A. Immediate needle decompression (2nd intercostal space midclavicular line) followed by chest tube placement
• B. Administer high-flow oxygen while delaying procedures
• C. Perform chest X-ray at bedside first
• D. Initiate CPR and wait for definitive therapy

Answer: (A)

Relieve the pressure that is compromising circulation. In a suspected tension pneumothorax during arrest, air trapped in the pleural space builds up pressure that collapses the affected lung and compresses the great veins, sharply reducing venous return to the heart and worsening the arrest. The first, time-critical step is to decompress this tension immediately to restore circulation, then provide definitive chest tube drainage to re-expand the lung and prevent reaccumulation. Needle decompression is performed promptly to relieve the buildup of pressure—commonly done in the second intercostal space at the midclavicular line on the affected side—so blood can start perfusing vital organs again. Once decompression has occurred, a chest tube is placed for ongoing drainage and lung re-expansion as definitive management. Delaying decompression in favor of oxygen alone, delaying procedures, or waiting for imaging are inappropriate because they waste precious seconds and allow the life-threatening pressure to persist, worsening outcomes. CPR remains essential, but it does not substitute for immediately relieving the tension that is choking circulation.
