The SAM Chest Seal Combo Pack includes one vented chest seal and one non-vented chest seal. This allows the responder to deal with both entry and exit wounds in cases of through-penetrating traumatic chest injuries. The valve allows air to flow out of the chest cavity at low resistance while preventing ingress and prevents internal blockage. The domed shape of the valve was designed to prevent obstruction of the air channels from items such as blankets, clothing, and body armor.
