Quick Answer
A tension pneumothorax in survival situations can be identified by sudden onset of severe chest pain, difficulty breathing, and a feeling of being unable to draw air into the lungs. The victim may also exhibit signs of increased heart rate, decreased blood pressure, and a notable trachea deviation to the opposite side. Immediate action is required to prevent further complications.
Recognizing the Signs
A tension pneumothorax often presents with a sudden and significant increase in respiratory distress, making it crucial to act quickly. The victim may exhibit a noticeable decrease in respiratory rate, a significant increase in heart rate, and a drop in blood pressure. The absence of breath sounds on one side of the chest, often accompanied by a hyper-resonant sound, can also indicate a tension pneumothorax. Additionally, the trachea may be deviated to the opposite side due to the increased pressure in the thoracic cavity.
Performing Needle Decompression
In a survival situation, needle decompression is a critical technique to relieve the pressure buildup in the thoracic cavity. Using a 14-gauge over-the-needle catheter or an IV catheter, insert the needle at the second intercostal space, mid-clavicular line, in the affected side. Rotate the needle 90 degrees to break the skin and then insert the catheter into the chest cavity. Attach a 3-way stopcock to the catheter and connect it to a portable suction device or allow the air to escape slowly. Monitor the needle decompression technique closely to ensure the tension pneumothorax is relieved. A significant decrease in chest pain and improvement in respiratory distress should be observed within a few minutes of decompression.
