Multiple Choice

What is the preferred site for needle decompression of a tension pneumothorax?

When treating tension pneumothorax, the goal is to vent the pleural space as quickly as possible. The preferred site is the second intercostal space at the midclavicular line, with the needle inserted just above the upper border of the third rib. This targets the apical pleural space for rapid decompression and keeps the needle high enough to avoid the heart on the left side and other structures lower in the chest. Inserting above the rib is important because the intercostal vessels and nerves run along the inferior border of each rib, and going under the rib increases the risk of vascular or nerve injury. Lower or more laterally sites are less effective for rapid apical decompression and may pose additional risks to surrounding organs.
