Hyperbaric Oxygen: So how does it work ?

I thought a little more technical inside wouldn't hurt, so here is what I found on one of the
chamber manufacturer's home page:

"Hyperbaric chambers, used in hyperbaric therapy (HBOT), are any number of enclosures, which can be pressurized to allow a person inside to experience higher atmospheric pressures than the normal environmental pressures.  For example, a treatment at an elevation of 12,000 feet above sea level using a 4 psi (1.27 ATA) can simulate a decent of ~5,843 feet to 6,157 feet above sea level.

At higher elevations, the barometric pressure is lower.  This decrease of pressure also decreases the oxygenation of blood, and is known as anoxia—where molecules of oxygen exert less pressure on the walls of the alveoli (Dalton’s Law). Hyperbaric Oxygen Therapy (HBOT) follows this law.

How does hyperbaric oxygen therapy (HBOT) work?

Hyperbaria - Increased atmospheric pressure as a means of increasing
oxygen uptake without an enriched oxygen source
Hyperoxia - Increased total oxygen content

Hyperbaria is based on the concept of the relationship of gas pressure and uptake in liquids (blood, plasma and tissues).  Henry’s Law states that “a gas is dissolved by a liquid in direct proportion to its partial pressure.”  For example, at sea level, atmospheric pressure is 760 mm Hg, the oxygen concentration is 21% and the body’s oxygen content or partial pressure, pO2, in blood and plasma is ~ 40 mm Hg.

Red blood cells have a limitation as to how much oxygen can bind with hemoglobin.  The plasma portion of the blood typically has about a 3% oxygen concentration.

By placing someone in a 3 psi pressure hyperbaric environment, the increase in atmospheric pressure at sea level goes from 760 mm Hg to 915 mm Hg.  This increase in gas pressure, increases the partial pressure of the oxygen gas and thus forces more oxygen to be dissolved in the plasma.  This saturation of oxygen in the blood, due to the Hyperbaric Oxygen Therapy or HBOT, allows the extra oxygen to be diffused or transported to the surrounding body tissues.  Thus, oxygen transport by plasma is significantly increased under hyperbaric therapy (HBOT).  At three atmospheres pressure, enough oxygen can be dissolved in the plasma to support the oxygen demands of the body at rest in the absence of hemoglobin!

Hyperbaric Oxygen Therapy (HBOT) is designed to boost the supply of oxygen to ischemic tissue or to diseased tissues that respond to increased oxygen levels.  Increasing the volume of oxygen dissolved in the blood plasma, that is brought about by hyperbaric therapy (HBOT), produces five basic effects:

    * Reduction of volume of gas bubbles in the blood
    * Vasoconstriction, which reduces edema and secondary hypoxia
    * Restoration of aerobic metabolism to ischemic tissue
    * Detoxification of poisoned tissues
    * Enhanced phagocytosis

Henry’s Law- Henry’s law states that for a gas-liquid interface the amount of the gas that dissolves in the liquid is proportional to its partial pressure.  So Henry’s law helps to predict how much gas will be dissolved in the liquid.  The actual amount also depends on the solubility of the gas as well as its partial pressure.

Dalton’s Law-John Dalton observed that the total pressure of a gas mixture was the sum of the pressures of each of the gases if they were to exist on their own."

This is another success story I came across. I can really relate to
this one.


"The past year has been an amazing journey from stress and poor
health to energy and a new sense of well-being.

When I began working with this wellness center, I was disabled
by my inability to think straight, to concentrate or to recall simple
words and facts. Stress, poor nutrition, lack of exercise and
an overabundance of chemicals in my life and diet had contributed
to my ill health. I followed the program they recommended
religiously and now feel like a new person ! A very important
milestone was reached recently when I managed to take myself off
of antidepressants. During that process I went to them in desperation
feeling as though I was relapsing into confusion and depression.
They immediately recommended an injection for stress and had me
spend some time relaxing in the hyperbaric oxygen chamber.
On my way home I realized that I had the energy to seek out a piece
of music I had been wanting to play for months. Unable to find the
chart in stores, I purchased the CD and spent the rest of that
afternoon and the next morning doing something I haven’t been
able to do in two years. I patiently and methodically listened to the
music on the CD and created a very complete chart from which I
could play the melody, harmony/chords and bass line.
This may sound easy to many musicians, but I had feared this
level of concentration was lost to me forever. The whole process was
enjoyable and invigorating. I know the Chamber helped bring me
to that place and I thought you’d like to hear about it. Thanks.
V.S., Los Angeles"

This really matches my own experiences about increased focus and
concentration. I do 3 treatments a week myself and I can tell
the increase in energy.
Until next week :)
