A 22-year-old man is brought to the emergency department after a motor vehicle collision. He is in severe respiratory distress. Vital signs show a blood pressure of 82/50 mm Hg, pulse of 135/min, and oxygen saturation of 84% on room air. Examination shows distended neck veins, tracheal deviation to the left, and absent breath sounds over the right hemithorax. Arrange the following management steps in the most appropriate chronological order.
- 1Perform immediate needle or finger thoracostomy
- 2Insert a tube thoracostomy
- 3Obtain a portable chest radiograph
- 4Admit to the hospital for continuous monitoring
Answer
The correct sequence is to first perform immediate needle or finger thoracostomy, followed by inserting a tube thoracostomy, then obtaining a portable chest radiograph, and finally admitting the patient for continuous monitoring.
The correct sequence prioritizes immediate life-saving intervention based on clinical diagnosis, followed by definitive stabilization, and then diagnostic confirmation. Tension pneumothorax is recognized clinically by hypotension, jugular venous distention, tracheal deviation, and absent breath sounds. It causes obstructive shock by impairing venous return. The very first step is immediate decompression via needle or finger thoracostomy to restore cardiac output. This is directly followed by a tube thoracostomy (chest tube) for definitive continuous drainage. Only after the patient is hemodynamically stabilized and the chest tube is placed should a portable chest radiograph be obtained to confirm placement and assess the lung. Finally, the patient is admitted for ongoing trauma monitoring.

Key Concept
Tension pneumothorax is a life-threatening clinical diagnosis requiring immediate empirical decompression (needle or finger thoracostomy) followed by definitive chest tube placement, entirely prior to obtaining confirmatory imaging.
