What is HBOT?

Hyperbaric Oxygen Therapy

Hyperbaric Oxygen Therapy is a method of administering pure oxygen at greater than atmospheric pressure to a patient in order to improve or correct conditions. Providing pure oxygen in a pressurized chamber we are able to deliver 10-15 times more oxygen than if delivered at sea level or at normal atmospheric pressures.

How

How does HBOT help speed the healing process?

Nature has dictated that healing cannot take place without appropriate oxygen levels in the body’s tissues. In many cases, such as those involving circulatory problems caused by things like diabetes, strokes, anoxic brain injury, and near drowning just to name a few, adequate oxygen cannot reach the injured area and therefore the body’s natural healing process fails to function properly. 

Oxygen given with increased pressure can correct many serious health problems. To provide this increased pressure one must be within a pressurized room, a Hyperbaric Oxygen Chamber. Oxygen, given at normal atmospheric pressure is insufficient to raise tissue oxygen levels significantly above normal. The answer is to deliver oxygen with a slight increase in pressure with a chamber, thereby causing the oxygen to go into solution in the plasma and tissues, raising oxygen levels significantly above that which can be achieved at normal pressure. 

How does HBOT allow more Oxygen to be absorbed into the bloodstream and tissues?

Blood is made up of three main components: white cells that fight infection, red blood cells that carry oxygen, and plasma, the fluid that carries both kinds of cells throughout the body. Under normal circumstances, only the red blood cells carry oxygen. However, because HBOT allows more oxygen into the body under pressure, Oxygen dissolves into all of the body’s fluids, including the plasma, the lymphatic fluids, and the cerebrospinal fluids surrounding the brain and spinal cord. These fluids can carry the extra oxygen even to areas where circulation is poor or blocked, either by trickling past the blockages or by seeping into the affected area. 

This extra oxygen helps in the healing process and enhances the white blood cells’ ability to fight infection. It can promote the development of New Capillaries, the tiny blood vessels that connect arteries to veins. It also helps the body build new connective tissue. In addition, HBOT helps the organs function in a normal manner. 

As we age, we can lose vital lung capacity and the ability to effectively obtain adequate Oxygen. Some disease conditions impair oxygen utilization. In addition, with injuries or conditions where there is swelling or edema, this causes pressure within the tissue, which cuts off circulation flow. 

For years, conventional medicine thought of HBOT only as a treatment for decompression sickness........ 

However, this is about to change the scope of medicine as never before. The Use of HBOT is becoming increasingly common in general practice as more doctors become acquainted with new applications. Doctors now realize that HBOT has other uses, including the treatment of non-healing wounds, Carbon Monoxide poisoning, various infections, damage caused by radiation treatments, near- drowning, near-hanging, brain and nerve disorders, cardiovascular disorders; and some digestive system disorders. 

It is important to realize that, in most cases, HBOT is best used when combined with other treatments such as physical therapy and or surgery. 

In the USA, the situation stands in marked contrast with many other countries, where HBOT is used for a much wider range of conditions. Multiple Sclerosis patients have banded together in Britain to create their own network of Hyperbaric Chambers. Centers in China treat more than 100,000 patients each year for a multitude of medical conditions.

Why is Oxygen so important?

Oxygen is a colorless, odorless gas that makes up about 21 percent of the atmosphere. It is essential to life for two reasons:

  • Oxygen is one of the body’s basic building blocks. All of the body’s major components, water, protein, carbohydrate, and fat contain oxygen.

  • Oxygen helps bring about certain chemical reactions within the body that result in energy production. Energy is needed for functions such as circulation, respiration, and digestion. Energy is also used to maintain a constant body temperature.

If the body is totally deprived of Oxygen, death results within minutes. A diminished supply of oxygen causes multiple symptoms, some of which are mental disturbances, shortness of breath, and rapid pulse, a fall in blood pressure and cyanosis, a blueness of the skin and mucous membranes. This results in a marked reduction in all bodily functions. This condition is known as hypoxia, or under-oxygenation of the tissues.

Oxygen, The new Growth Factor?

In recent years, our understanding of the intercellular communication of healing has increased considerably. Cells within a wound receive a myriad of signals from their environment, the sum of which governs the activity of a cell. The term "cytokine" is applied to those substances which function as cellular signals. Growth factors are a subclass of cytokines that specifically stimulate the proliferation of cells. This stimulation may occur through several different mechanisms. For example, some growth factors have activities that attract fibroblasts and inflammatory cells, some act as mitogens, stimulating cell division, and some effect the production and degradation of the extra-cellular matrix. All of these phenomenons are the result of a cytokine (growth factor) signaling the cell nucleus to produce proteins, which account for the observed activities. A clear understanding of growth factor physiology carries the promise of clinical advances in wound management. Currently one cytokine, Platelet Derived Growth Factor, is in clinical use for the management of problem wounds. As our knowledge of these substances expands, other growth factors will be added to our clinical armamentarium for the management of non-healing wounds. 

Non-healing wounds can also be managed by optimizing the metabolic requirements of healing e.g. protein, trace elements, and oxygen. The most frequent common denominator in non-healing wounds is inadequate tissue oxygenation, which impairs healing and host defenses. Correction of such hypoxia by means of revascularization or hyperbaric oxygen therapy results in healing for most patients. Conventional wisdom suggests that oxygen is just a metabolite and therefore healing, in these circumstances, is simply a reflection of having sufficient oxygen to meet the energy demands of wound repair. However, some exciting evidence is now emerging to suggest that oxygen serves a dual role as both a metabolite and a growth factor. The conceptualization of oxygen as a growth factor has considerable relevance to the field of hyperbaric oxygen therapy. 

The idea of oxygen acting as a cell signal has already been established in the setting of hypoxia. As an example, gene expression for erythro-protein production is largely proportional to the pO2 level in the kidney. It has been proposed that cells in a non-healing wound may respond to hyperbaric therapy because the supra-physiologic elevation of tissue oxygen serves as a trigger signaling that enough oxygen is in the environment to proceed with normal healing. Subsequent daily exposure to the threshold oxygen level reinforces this signal and results in gene expression of the protein building blocks required for healing. Teleologically, it makes sense for cells to conserve resources until the environmental signals are strong enough and consistent enough to activate the cell nucleus and begin the healing process.

Two separate groups of investigators have published findings that support this concept of oxygen as a growth factor. Following a single one-hour exposure to hyperbaric oxygen, Hehenberger, et al. (1997) demonstrated a dose dependent stimulation of normal in vitro fibroblasts with a peak increase in cell proliferation at 2.5 ATA O2. The dose-dependent effect of a single 1-hour exposure to oxygen suggests a pharmacologic effect of oxygen on cells, as opposed to an increased metabolic availability of oxygen. These findings suggest, therefore, that a single brief exposure to hyperbaric oxygen on a daily basis provides a strong initiating signal for the intracellular events that culminate in cell proliferation, while sustained hyperoxia has the opposite effect. 

In a study of in vitro fibroblast proliferation using tritium labeled thymidine, Tompach, et al., found that a single dose of HBO (2.4 ATA for 120 minutes) produced a sustained stimulation of fibroblasts for 72 hours. If a second exposure to HBO was given on the same day there was no additional increase in cell proliferation. Similarly, cultured endothelial cells remained stimulated for 72 hours following a single 15-minute exposure to HBO. Again, these findings suggest that we must reconsider oxygen as being more than just a metabolite. 

This new paradigm of oxygen as a growth factor is consistent with the clinical observation that a BID dosing of HBO appears to offer no clear benefit over a QD dosing schedule for the treatment of chronic wounds. As our understanding of oxygen physiology increases, we will be in a better position to determine the optimal dosing of oxygen in both its metabolic and stimulatory roles.

This Month's Tip

Diabetes is a growing epidemic in the United States. An estimated 14.6 million Americans have been diagnosed with diabetes, and another 6.2 million people are unaware that they even have the disease, according to the American Diabetes Association. What's more, 54 million Americans have prediabetes, a condition in which blood sugar levels are higher than normal, but not yet high enough to become diabetes.

Preventing and managing diabetes is completely within your control. "Lifestyle changes can have a major impact on diabetes," says Tracy L. Breen, MD, Clinical Director of the Mount Sinai Diabetes Program and Assistant Professor of Medicine in the Department of Endocrine, Diabetes, and Bone Diseases at Mount Sinai. "You can do a lot to offset the progression of diabetes by watching your weight, eating right, and exercising, such as walking for 30 minutes, five times a week."
