A soft, sterile dressing made of calcium-sodium-alginate fiber that converts to a firm gel/fiber mat on contact with fluid. It is designed to absorb exudate and control minor bleeding. It may be appropriately used for use on moderately to heavily exuding wounds, including Stage II–IV pressure ulcers, venous ulcers, arterial and diabetic ulcers, donor sites, superficial burn wounds, lacerations and abrasions, traumatic wounds, and postsurgical wound debridement.
