HBOT is an FDA approved treatment for both crush injuries and compartment syndrome. Wounds need oxygen to heal properly. When a person is crushed by an object, the object puts pressure on the body, disrupting the flow of blood and starving the area of oxygen. HBOT floods the area with oxygen, helping to reduce swelling and helping cells and tissue to repair and heal. Sometimes used in conjunction with traditional therapy, hyperbaric oxygen therapy also helps blood vessel and collagen formation, which further improves recovery.
