Needle aspiration at the second intercostal space is performed in cases of a tension pneumothorax. This procedure is vital because a tension pneumothorax occurs when air becomes trapped in the pleural space and exerts pressure on the mediastinum, leading to compromised venous return and reduced cardiac output. Performing a needle decompression allows for the immediate release of the trapped air, which can quickly alleviate the pressure and restore normal respiratory and hemodynamic function.

In contrast, pneumonia, pulmonary embolism, and congenital heart disease do not require needle aspiration at the second intercostal space. Pneumonia is primarily treated with antibiotics and supportive care, while pulmonary embolism often requires anticoagulation or other interventions specific to clot management. Congenital heart disease involves a range of surgical or interventional cardiology approaches to correct structural defects rather than needle aspiration.
