Heart Benefits of HBOT therapy

I am relatively new to RSD/CRPS I. That being stated, I research this disease to understand what I can do to heal/help myself..be it knowledge, pt, etc.

I believe a discourse of this subject is best weighed out on an individual basis; specifically, on a case by case basis. Each of us are individuals thus one treatment for one may not be good for another.

I found this article to be beneficial to the HBOT discussion:

http://www.rsds.org/3/research/hbot_mcadamshtm.htm

I hope this broadens the discussion on HBOT therapy, whereas a decision can be made with all sides being discussed.

Default Here you go Dew and Numb

There are always many sides to one issue as you stated earlier Dew. But, here is an link I think will explain more in detail and easy to follow:
http://www.vet.utk.edu/vhms/pdf/Free...genSpecies.pdf
The Physiology of Hyperbaric Oxygen Therapy
Free Radicals and Reactive Oxygen Species
I. Introduction – Definition, Source, function and Purpose
A. Definition of free radicals and reactive oxygen species (ROS).
1. Reactive oxygen species (ROS) are highly reactive ions and
“free radicals” (chemicals containing atoms with an
unpaired electron in its outer orbit) involving oxygen
molecules.
2. “Free radicals” are present that do not contain oxygen, but
ROS refers to free radicals containing oxygen molecules.
3. Characteristics:
a. Short lived
b. Unstable
c. React with other molecules to achieve stability
B. Source of ROS’s
1. Byproduct of cellular respiration (presence of redox cycling
compounds).
2. Synthesized by enzyme systems – phagocytic cells,
neutrophils and macrophage (NADPH oxidase,
myeloperoxidases).
3. Exposure to ionizing radiation
4. Smoking, herbicides, pesticides, fried foods, etc.
5. Production:
a. Chain reaction, a free radical steals an electron from
a nearby compound forming a new free radical.
Free radicals may steal electrons from cellular
structures or molecules.
b. By normal cellular respiration – electron transport
system – often oxygen is the terminal electron
acceptor in the cell mitochondria �� ROS
c. Figure on production of common free radical
species.
2
C. Function and purpose
1. Necessary for production of some hormones (thyroxine).
2. Generated to kill some types of bacteria and engulfed
pathogens.
3. Normal cell functions and cell signaling.
4. A balance:
a. Free radicals generated by normal processes do
become harmful if inadequate anti-oxidant defenses
are present. A balance between production and
removal/inactivation is required.
b. When free radicals are present in excess of the
defense mechanism’s ability to control them is
when damage may occur.
c. Anti-oxidants – compounds which will provide
electrons to free radicals to neutralize them. The
compounds are able to accommodate the loss of an
electron without becoming reactive.
d. Anti-oxidants: Vitamin E, SOD, catalase,
glutathione peroxidase, Vitamin C, beta-carotene,
coenzyme Q.
D. Free radicals in disease. Excessive free radical production has
been involved in the occurrence in several disease processes.
1. drug toxicities
2. inflammation
3. aging
4. fibrosis
5. carcinogenesis
6. lipid peroxidation cellular membranes
7. implicated in several specific diseases
a. atherosclerosis
b. degenerative neurologic disease
c. reperfusion injury
8. oxygen toxicity
Triplet Oxygen Superoxide anion Hydrogen peroxide Hydroxyl radical Water
+e- +e- +e- +e-
3O2 ----------> • O2
- ---------- > H2O2 ---------> •OH ------------> H2O
+H+ +H+ +H+ +H+

II. Reactive Oxygen Species
A. Individual species
1. Superoxide anion
a. • O2
-
2. Hydroxyl radical
a. • OH
3. Hydrogen peroxide
a. H2O2
4. Nitric oxide
a. • NO
5. Hypochlorite ion
a. OCl-
6. Ozone
a. O3
7. Thiyl radicals
a. RS •
8. Carbon centered radicals
a. • O2CCl3

III. HBOT and ROS’s
A. ROS affects depend on;
1. balance with anti-oxidant production
2. physical condition of the patient
3. concentration, frequency and duration of hyperbaric
oxygen exposure.
B. Exposure limits
1. 2.5 ATA and less �� no significant increase in ROS
production.
2. Frequency and duration of treatment that might
significantly increase ROS production in horses is not
known.
a. The limits of accumulative or acute exposure to
hyperbaric oxygen have not be established.
C. HBOT and benefits of ROS production
1. Enhancement of antimicrobial effects of cellular immunity
especially in hypoxic environments.
2. Some evidence exists that indicating that HBOT may
actually decrease lipid peroxidation in cell membranes.
4
IV. Facts about free radicals, ROS, and hyperbaric oxygen therapy.
A. Hyperbaric oxygen therapy using pressures at or less than 2.5
ATA do not significantly increase ROS in the presence of normal
anti-oxidant defenses.
B. The detrimental effects of ROS is seen when there is an
imbalance between ROS production and the bodies anti-oxidant
production or availability.
C. ROS are generally a family of compounds that are short lived,
unstable and highly reactive and will react with cellular
molecules to achieve stability.
D. A certain amount of ROS are produced by normal cell
respiratory functions through the electron transport system.
E. ROS and free radicals have an important role in the oxidative
killing of micro-organisms.
F. A variety of anti-oxidants are either produced by the body or
provided by dietary absorption for use in maintaining the balance
between ROS and anti-oxidant defenses.

Default By the Way

1.5ata to 2.4ata is the general protcol for HBOT for RSD/CRPS. I usually dive at 1.8ata. I also have a antioxidant rich diet and take antioxidant suppliments ie:vitamin e, grapeseed extract and pine bark. I juice daily and eat plenty of raw veggies. Oh, you can also have damage from too much antioxidants.....moderation is key here on the suppliments. Also, aging increases OFR, diet, medicines and environment. HBOT is a personally choice, just as pharmacueticals are. It is cost prohibited and I think THAT is the shame. Just my 2cents worth. Di
