The Asherman Chest Seal™ is a proven treatment for open pneumothorax and the prevention of tension pneumothorax in chest injuries from gunshot, stab wounds or other penetrating chest injuries. The unique one-way valve is designed to let air and blood escape, while keeping both out of the pleural cavity.

Features include a circular design with a one-way valve and a special pressure-sensitive adhesive that ensures an effective seal, even over body hair. Its easy-open packaging keeps the ACS™ sterile prior to use. The dressing is 5½" in diameter and is clear, permitting visual monitoring. A gauze pad is included for removing fluids and debris prior to application.
