In suspected tension pneumothorax, what is the first priority in prehospital management?

• A. Administer pain medication.
• B. Perform chest percussion to assess air.
• C. Obtain a chest X-ray.
• D. Provide high-flow oxygen and rapid transport.

Answer: (D)

In suspected tension pneumothorax, the immediate priority is to maximize oxygen delivery and get the patient to definitive care as quickly as possible. Tension pneumothorax can rapidly worsen oxygenation and hemodynamics as air accumulates and compresses the lung and mediastinal structures, reducing venous return. Providing high-flow oxygen supports tissue oxygenation and overall perfusion, while rapid transport ensures access to definitive treatment (such as decompression and chest tube placement) without delay. Other actions like giving pain meds, performing chest percussion to “check air,” or obtaining a chest X-ray in the field do not address the life-threatening physiology and would slow necessary care.
