Hains,

Welcome to NeuroTalk. HBOT has been discussed at length in this forum. There is a clinical study currently taking place for PCS patients and HBOT. A few have been able to enroll in it. I see you have found Dr Harch's web site.

Dr Harch claims to use 100% oxygen but that is only possible with a mask. Most HBOT patients do not tolerate masks very well. The studies published to date show little difference between 100% oxygen and normal oxygen levels (21%) and little difference between 1.25 or 1.5 atmospheres and higher pressures except higher pressure can cause latent side effects.

Your points : First HBOT does not decrease the size of oxygen molecules. The molecules are closer together (crowded) but each molecule is always the same size.

BHOT works on a few principles. Gas pressure (partial pressure) across a membrane and the breaking of the binding of some gaseous molecules that displace other gaseous molecules. HBOT is needed to displace CO (carbon monoxide) molecules with O2 molecules.

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.

Research suggest that HBOT increases capillary growth. It does not increase oxygen saturation in the blood by any substantial level ( spO2 is usually 97 to 98% at one atmosphere)

From what I know, chelation might be a way to remove calcium. But, forcefully removing calcium would risk calcium that is important like in bones. Or, better balancing of the calcium interacting elements might do the job better. Anti-oxidants help the tissues maintain balance better.

Could this calcium buildup be due to ineffective glymph functions ? Improving glymph function would help.

Many with PCS get stuck on a single narrow concept as their primary issue. That is rarely the case.

Are you still struggling with some symptoms that defy your understanding ?
