What is the standard field needle decompression site for suspected tension pneumothorax in adults?

In a suspected tension pneumothorax, fast relief of trapped air is life-saving. The standard field decompression site is the second intercostal space at the midclavicular line, with a large-bore needle aimed toward the apex of the chest. This location gives the quickest access to the pleural space and venting path for air under pressure, while keeping the entry point away from the heart and most abdominal organs. A large-bore needle is chosen to allow rapid decompression despite the high intrapleural pressures. After decompression, chest tube thoracostomy is performed as definitive management. Other sites are not ideal for immediate decompression: they either don't reach the pleural space reliably, pose greater risk to underlying organs, or are intended for other procedures (for example, subxiphoid access is for pericardiocentesis).
