Finger Thoracostomy for Tension Pneumothorax.

One of the injuries associated with chest trauma is pneumothorax, a condition where air accumulates between the parietal and visceral pleura in the chest leading to collapse of the lung due to pressure. Left untreated, a tension pneumothorax may develop leading to cardiovascular collapse. This article reviews the development of a tension pneumothorax, discusses the clinical recognition of the diagnosis, and outlines the procedure for performing a finger (or simple) thoracostomy. A simple mnemonic for the procedure is offered as a memory aid to reduce cognitive load for this procedure.
