A chest seal is indicated when a patient has penetrating chest trauma from neck to navel, on the front, side or back of the chest. The chest seal doesn't control bleeding inside the chest cavity. Instead, the chest seal prevents air from entering the chest cavity.
The HCVI/MOAS protocol will be to use a non-vented chest seal (an appropriately sized hydrocolloid dressing (2x2, 4x4).
ANY patient with a penetrating chest wound should be CONTINUOUSLY observed for the development of a TENSION PNEUMOTHORAX.
