Needle decompression would be the correct intervention for a pneumothorax, but it would not effectively treat a hemothorax because the caliber of an angiocath would be much too small to effectively drain blood out of the chest — the flow would be so slow that there would be no impact on the tension physiology, even if the proceduralist tried to aspirate it as quickly as possible. This case demonstrates the risk of tension hemothorax as a complication of CVC placement, the value of the physical exam in distinguishing between hemothorax and pneumothorax, and the importance of treating a hemothorax with a large-bore chest tube. Many predisposing factors are strongly linked to atelectasis and pneumothorax.
