One-way chest seals are an alternative to decompression needles for treatment of a tension pneumothorax. In June 2013 USCENTCOM approved the following...
“All open and/ or sucking chestwounds should be treated by immediately applying a vented chest seal to cover the defect. If a vented chest seal is not available, use a non-vented chest seal. Monitor the casualty for the potential development of a subsequent tension pneumothorax. If the casualty develops increasing hypoxia, respiratory distress, or hypotension and a tension pneumothorax is suspected, treat by burping or removing the dressing or by needle decompression”
A pneumothorax is a collapsed lung. Pneumothorax occurs when air leaks into the plural space between your lungs and chest wall.
A tension pneumothorax is the progressive build-up of air within the pleural space usually due to an open wound, caused by a blast injury, gunshot wound, knife stabbing etc. to the chest area. Air enters the pleural cavity and is trapped during exhale; air pressure builds within the thorax higher than external atmospheric pressure which compresses the lung. This compression can place pressure on the heart and lung.

This IFAK contains tools which are designed for quick and intuitive application. If you don't know how to use a decompression needle that doesn’t mean you can’t render aid to someone with a tension pneumothorax. This kit contains a total of 4 chest seals (2 HALO, 1 Asherman w/1-way valve, 1 Vaseline occlusive dressing). The ASHERMAN chest seal is specifically designed to treat an open Pneumothorax and help prevent the onset of a Tension Pneumothorax in open chest injuries. The Asherman seal utilizes a one-way valve which allows air and blood to escape while preventing air from reentering through the wound site.
