How Does Hyperbaric Oxygen Therapy Help Stroke Recovery

Hyperbaric Oxygen Therapy (HBOT) is the administration of 100% pure oxygen under greater than normal atmospheric pressure. Although it has only recently gained widespread attention in the United States, HBOT has been used for over 100 years. While it was originally developed for the bends, a diving injury caused by air bubbles in the bloodstream, HBOT’s numerous healing effects have since been recognized. HBOT aids in recovery from so many conditions that it has been described as “a therapy in search of diseases.” By pushing higher levels of oxygen deeper into the body’s systems, HBOT has successfully given life back to a wide variety of patients.

Generally speaking, strokes can be classified as either ischemic or hemorrhagic. Approximately 80% of all strokes are ischemic (Grysiewicz et al., 2008). Current studies have shown that both hemorrhage within the brain and primary ischemia can cause a lack of oxygenation and nutritional supply and a series of neurochemical events that lead to spreading brain damage.1  This inhibits nutrients and blood supply from reaching the damaged parts of the brain and has traditionally made healing limited, if not impossible.

How does Hyperbaric Oxygen Therapy improve patients’ healing? HBOT increases the  dissolved oxygen levels in plasma and can even nourish tissues in the absence of red blood cells.2 HBOT also promotes capillary development throughout the body. These changes bring more oxygen and nutrients to cells in need of healing. Hyperbarics solves one of the root dilemmas of stroke recovery by improving nutrient and oxygen circulation to damaged tissues. This allows patients to focus their efforts on training the body to adapt to its rehabilitated function through programs such as neuro physical therapy and neurofeedback.

Hyperbaric Oxygen Therapy can give stroke patients back their lives by improving strength, endurance, balance, coordination, motor skill, verbal skill, and memory recall. These improvements can provide the patient a greater level of independence than before. Additional benefits of HBOT in stroke patients include: improved oxygenation, reduced intracranial pressure, improved metabolic rate of cerebral tissue, and inhibited post-stroke cell apoptosis and necrosis.

If a stroke has left you or a loved one debilitated with a loss of fine motor skills, inability to walk, or brain imbalance, let Oxford Recovery Center conduct a FREE evaluation of your disorders in order to develop a customized recovery plan. Oxford Recovery Center Integrates Hyperbaric Oxygen Therapy in conjunction with Neuro Physical / Suit Therapies and Neurofeedback Programs to accelerate the development of new motor skills that strengthen muscles and teach the brain and body how to sit, stand and walk again. Call The Oxford Center today at 248-486-3636 to schedule an appointment at their Brighton or Troy, Michigan locations.

HARD VS SOFT CHAMBERS HYPERBARIC OXYGEN THERAPY CHAMBERS

The question is not can you, but is it safe and effective. First of all, you cannot legally put a real hyperbaric oxygen therapy chamber into your home. In addition to the National Fire Protection Association (NFPA-99) regulations and the illegality of medical-grade oxygen purchase, it just would not be safe.

What can you legally put into your home? (This is in the US; Canada does not allow even mild hyperbarics in the home.) The question about what is the difference between hard-sided medical grade hyperbaric oxygen chambers and inflatable hyperbaric chambers (mild/soft hyperbarics) is a common asked question. At The Oxford Center, we use only hard-sided Sechrist chambers. If inflatable bags were an effective treatment modality it would only make sense for us to use them, as the cost would be immensely less expensive for the chamber cost, oxygen (tank, plumbing, corral, and gas), not to mention the extensive NFPA-99 regulations for the build-out. However, hyperbaric oxygen therapy is NOT the same as the mild hyperbarics.

To compare the differences, let’s look at the oxygen in the blood. We measure the changes from arterial blood gases. Arterial oxygen at 2.4 ata 100% oxygen is 1,824 mmHg (normal air pressure is 157mmHg). This refers to how much oxygen is getting into the body, what is making the changes. Compared to using mild/soft chambers, the arterial oxygen at 1.3 ata 24% oxygen is 230 mmHg (normal air pressure is 157mmHg).Now Consider this: If you have a non-rebreather oxygen mask hooked up to an oxygen tank (the oxygen mask you see paramedics use when transporting a patient), the mask can deliver about 55% oxygen. The percentage is used by using the conversion equation (1ATA x 760mmHg x0.55=418mmHg). The moral of the story is that an oxygen mask can deliver a higher amount of oxygen than an inflatable bag so why would you expose yourself to the time and expense for such little benefit.

Let’s examine the reasons why we do NOT use inflatable bags and we do NOT call them hyperbaric oxygen chambers. For a quick comparison:

Hard ChamberSoft Chamber
100% medical grade oxygenAmbient air (approximately 21% oxygen—mostly nitrogen)
Pressurized typically to a max of 3.0 ATA or depth of 66 feet (Some go to 6.0 ATA or 165 feet)Pressurized to a max of 1.3 ATA or depth of 8 feet
Regrow bone and tissue in severely damaged areas of the bodyCannot regrow bone and tissue
Supported by thousands of clinical studies which validate successful healingNo such correlation has been made with soft chambers and healing
Many treatments are recognized for reimbursement by insurance companies and federal governmentNo conditions are reimbursed by insurance companies using soft/mild chambers
Designed to go to therapeutic pressures to achieve healingDesigned to temporarily treat divers and mountain climbers in route to a hard chamber
Kills harmful bacteriaCan promote the undesirable growth of aerobic bacteria
Meets the American Society of Mechanical Engineers, Pressure Vessels for Human Occupancy (“ASME PVHO-1”) standardDoes not meet the “ASME PVHO-1” standard
Loss of electrical power has no effect on pressure and oxygen flowLoss of electrical power and chamber rapidly deflates causing possible barotrauma to patient’s ears and pneumothorax to patient’s lungs
No risk of contaminated or polluted air. A closed system of oxygen is piped in directly from a liquid oxygen tank. The liquid oxygen is converted to a gas on-site and pumpled directly into the individual chamber. There is no outside air contamination.Risk of breathing contaminated or polluted air which can be counterproductive
Designed to heal ischemic tissue or tissue that is restricted from receiving enough oxygen by hyper-oxygenating the body, blood and plasmaNo research shows healing ischemic tissue
Research shows a total of 40 treatmentsSome results may be obtained in the lower pressure air filled chambers, however it will take many, many more sessions and the results often do not hold, or create issues with yeast or bacteria growth
Designed to use enriched gases like 100% oxygenNever designed to be used with enriched gases like 100% oxygen
