Hyperbaric Oxygen Therapy, or HBOT, is used as a treatment for difficult wounds that won't heal and that meet specific criteria. This is usually the case 10 to 20 percent of the time. Throughout these treatments, you will be watched to make sure the level of oxygen has increased in the blood near the wound. If the oxygen level is higher, the therapy is most likely helping.
During the treatments, the patient breathes 100 percent oxygen inside a pressurized chamber. This quickly increasing the amount of oxygen in the blood, which is what helps the wound heal. Essentially, HBOT therapy helps heal the wound from the inside out. This can help reduce swelling, fight infection and build new blood vessels. All of this helps the body make healthy tissue. HBOT is also effective in fighting certain types of infections, improving blood circulation, helping to grow new blood vessels, and in treating crush injuries, osteomyelitis, compromised skin grafts and flaps, brown recluse spider bites and diabetic wounds of the legs.
