Hyperbaric Oxygen Therapy – “HBOT”
An established and respected procedure in medical science worldwide.
HBOT is administered to patients, both humans and animals, within a closed, pressurised and manipulated environment, wherein the atmosphere (breathing air):
A) is kept very rich in oxygen (far more than the normal of 21% and up to 100% pure).
B) is kept pressurised to between 1.5 and 3 times normal atmospheric pressure.
(usually calibrated as 1.5 to 3 bar. Normal air pressure is measured as 1 atmosphere or about 1 bar).
C) carbondioxide and other noxiousgases are kept within defined limits.
Just being in such a pressurised oxygen rich environment for a period of time that can be as short as 30 minutes or up to many hours, has been proven to be very therapeutic (now even considered a cosmetic aid). However the true therapeutic values of HBOT are for patients, human or animal, who are undergoing various medical treatments or surgical procedures (whilst in an HBOT environment).
HBOT – How does work ?
The normal air (gases) breathed by living creatures, contains circa 78% nitrogen and just under 21% oxygen. The remaining 1% or so is made up of trace gases, such as carbon dioxide, argon, krypton, methane, neon, helium and hydrogen etc etc, together with water valour.
Red blood cells contain ‘haemoglobin’ which absorbs (takes up) oxygen from the lungs, transporting it in a dissolved form to all parts of the body. At normal atmospheric pressure, even rapid or deep breathing hardly increases the amount of oxygen carried by the bloodstream. And even breathing pure oxygen only slightly increases the oxygen content.
However, breathing while in a pressurised environment which is very oxygen rich, greatly enhances the oxygen-carrying ability of the blood due to oxygen being infused into the plasma as well as being carried by the red blood cells.
HBOT – Why does it enhance and accelerate healing ?
An abundant oxygen supply greatly stimulates the growth in bone and soft tissue of new blood vessels, which during and after medical treatments and surgical procedures, allows an increase in oxygen-rich blood reaching the damaged or infected parts of the body.
There is a decrease in swelling and/or inflammation, allowing more blood and therefore more oxygen to flow more freely to the effected areas.
A high oxygen level increases the ability of the white blood cells to kill bacteria in infected tissues. Anaerobic bacteria are killed directly by the high level of oxygen reaching infected tissues, even if normal circulation has been affected.
