Hyperbaric Oxygen Therapy (HBOT)

The Hyperbaric Chambers are a part of our Center for Wound Care healing tools. These non- invasive clear acrylic chambers provide 100% oxygen to promote the optimum healing opportunity. While breathing pure oxygen, the patient's blood plasma becomes saturated, carrying 20 to 30 times the normal amount of oxygen to the body's tissue. The ultimate result is the body's natural wound healing mechanisms (which are oxygen dependent) are able to function more efficiently. Continued use of HBOT increases the body's immune and healing response. Our Certified Hyperbaric Technician will educate you with the knowledge to complete this therapy program with the best results. Each hyperbaric chamber has its own TV/VCR and CD player for patients to watch movies or listen to music during treatment. The completely transparent chambers allow patients to see and be seen by the Hyperbaric Technician.

You're a Vital Part of the Program

Much of the success of your treatment depends on you. You must keep your appointments, follow directions carefully and watch your progress closely between visits. And any time you or your family members have questions, our staff is available. In fact, we encourage you to ask questions.

How We Work With Your Doctor

The Center for Wound Care and Hyperbaric Medicine works with your personal doctor, just like any other medical specialist. We'll discuss your treatment program with your doctor and keep him or her updated on your progress, unless instructed otherwise. Remember, you'll need to keep seeing your doctor for routine medical care.
