For suspected tension pneumothorax in the field, which action is recommended?

Relieving trapped air quickly is the priority with a suspected tension pneumothorax. Needle decompression directly vents the pleural space, lowering intrapleural pressure and restoring venous return to the heart, which can reverse the impending circulatory collapse in the field. This urgent intervention buys time before definitive treatment can be applied. Chest tube placement is definitive but requires more time and equipment and is typically done in a setting where the patient can be safely managed after initial decompression. Pericardiocentesis targets cardiac tamponade, not tension pneumothorax. Intubation with positive-pressure ventilation can worsen a tension pneumothorax by increasing intrathoracic pressure, potentially worsening the patient’s condition.
