What is the treatment for tension pneumothorax?

• A. Immediate needle decompression at 2nd intercostal space at midclavicular line
• B. Large-bore chest tube insertion in the 5th intercostal space midaxillary line
• C. Administer high-flow oxygen therapy only
• D. Observation and monitoring without intervention

Answer: (A)

The key idea is that tension pneumothorax is a life-threatening emergency that traps air under pressure and compresses the heart and great vessels. The fastest way to reverse that dangerous physiology is to relieve the trapped air immediately with needle decompression. Inserting a large-bore needle into the chest at the second intercostal space along the midclavicular line lets the air escape right away, rapidly improving venous return and blood pressure. This rapid decompression buys time to place a definitive chest tube to re-expand the lung and prevent recurrence. Oxygen helps with overall oxygenation but doesn’t fix the underlying pressure issue, so it isn’t sufficient on its own. Observation is inappropriate because the condition can deteriorate within minutes. While a chest tube is the definitive treatment, it takes longer to set up, and delaying decompression can be fatal.
