Being mercury toxic is also a BIG cause of oxidative stress which is an important reason that mercury toxic children and adults benefit from supplements.

Well, doesn't the phase " when supplementation was used " actually point to the idea that supplementation is NEEDED? Now, I'm not going to tell you that increased oxidative stress (from HBOT) is the ONLY reason that they might want supplementation -- but it seems really likely that they were, if fact, intentionally addressing oxidative stress. If I'm correct, what you've said really differs from " HBOT doesn't cause oxidative stress " . It's closer to " HBOT does cause oxidative stress, but it can be effectively mitigated by......

Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 > Unless they filled the chamber with pure oxygen, you can do better at room pressure with a mask than you can in an air filled chamber at less than 5 ATA. Andy, It think your comment here is giving a conclusion that would be helpful to break into parts a bit. Pressure alone results in oxygen being distributed in the body much better. I have forgotten the ATA at which there is an essential change, but at some level of pressure (a level that is considered fairly low pressure for HBOT), oxygen is carried by more aspects of blood and by lymph, and thus actually reaches many areas where it may not get carried just by red blood cells (which carry oxygen at " normal " levels of pressure). I can see it has been far too long since I've talked about this, I am not remembering half of what I want to say. Anyway, I expect that you know this, Andy, and that you still think that pure oxygen, with a mask, at normal pressure, would " do better " . I think 5 ATA is enough to greatly increase the efficiency of oxygen use/distribution. But, I don't remember the number. Ug. My addition to the conversation, which I hope may be useful for those trying to understand HBOT (and/or trying to make sense of what you said) is that HBOT generally refers to using more oxygen AND being under more pressure. EACH OF THEM results in more oxygen being available -- and BOTH TOGETHER is much more effective than either alone. What kind of mask also matters.

But, I don't remember the number. Ug. Ummm.... this is the part where the HBOT " used car salesmen " depend on the scientific illiteracy of most people so as to sell unnecessarily expensive service. Do you ever remember hearing about " partial pressure? " Which is to say, the pressure of the oxygen at ambient pressure is 0.21 ATA, the pressure of the nitrogen is 0.78 ATA and the pressure of the argon, neon, CO2, etc. is 0.01 ATA? The TOTAL pressure is 1 ATA of air, which is 0.21 ata of O2 + 0.78 ata of N2 + 0.01 ata of other stuff. The partial pressure of oxygen is what matters in your discussion here, the total pressure is irrelevant. Thus air at 5 ATA is equivalent to pure oxygen at 1 ATA. The oxygen carrying capacity of red blood cells (for those with normal lung and heart function) gets pretty fully saturated at near ambient conditions - that is, much above 0.21 ATA of oxygen. The oxygen carrying capacity of lymph, blood plasma, etc. is a linear function of pressure. At about 2.5 ATA of oxygen partial pressure in people with normal circulation and lung function it becomes equal to what the red blood cells are supposed to be doing. So if you just put on an oxygen mask at room pressure you increase 'normal' oxygen distirbution 40%, and in areas having a hard time getting the oxygen from red blood cells, you increase it far more. Many people who respond positively to HBOT also respond positively to just breathing straight oxygen through a mask, which is far easier and cheaper to arrange. Also one can REALLY get things going by doing exercise while breathing it through a mask so as to turn up the metabolism while extra oxygen is available. > My addition to the conversation, which I hope may be useful for > those trying to understand HBOT (and/or trying to make sense of > what you said) is that HBOT generally refers to using more > oxygen AND being under more pressure.

Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 ===> I realize that people who like to play gin rummy with pubmed abstracts can find one on any side of any issue. This fact alone makes it clear many of them are not correct. ---- In my view, this is due to the nature of the study of an open system having a vast number of independent variables. It's clearly an art form using a scienfitic methodology. But, I like your colorful metaphor ===> I am familiar with Dr. ' work, I do not believe any numbers about thiol species levels that come out of her lab. Even if they are accurate, GSSG is not the right measure of oxidative stress except while it is happening - unless blood was drawn in the HBOT chamber, this result is meaningless even if I accepted the measurement as accurate. ---- Perhaps it's the best one can do while dealing with live patient. ====> Actual facts are that HBOT makes about half of autistic kids temporarily better and about half temporarily worse. ---- I completely agree with you on this point, based on personal experiences mentioned in an earlier post. While heavy metal toxicty may be at the root of several sub, leads to a much more pervasive and confounding medical problem.

Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 Hi Andy, Well, this is interesting, since I read your comments as mostly saying what I said. [i said:] > > Pressure alone results in oxygen being distributed in the body > > much better. I have forgotten the ATA at which there is an > > essential change, but at some level of pressure (a level that > > is considered fairly low pressure for HBOT), oxygen is carried > > by more aspects of blood and by lymph, and thus actually > > reaches many areas where it may not get carried just by red > > blood cells (which carry oxygen at " normal " levels of pressure). [You said:] > The oxygen carrying capacity of red blood cells (for those with normal lung and heart function) gets pretty fully saturated at near ambient conditions - that is, much above 0.21 ATA of oxygen. Right, just the red blood cells are carrying oxygen at normal pressure [ambient conditions]. > > The oxygen carrying capacity of lymph, blood plasma, etc. is a linear function of pressure. At about 2.5 ATA of oxygen partial pressure in people with normal circulation and lung function it becomes equal to what the red blood cells are supposed to be doing. Right, like I said, PRESSURE results in oxygen being carried by additional mechanisms -- ncluding plasma, lymph and cerebrospinal fluid. (I looked it up, thus I remembered cerebrospinal fluid). [you said:] > So if you just put on an oxygen mask at room pressure you increase 'normal' oxygen distirbution 40%, and in areas having a hard time getting the oxygen from red blood cells, you increase it far more. um, yes, if " normal " means " via red blood cells " . And the 40% ONLY applies if 100% means 100% of what red blood cells can do -- so it can also be misleading, depending on how someone reads numbers. And, yes, in areas where the red blood cells are not reaching, you are increasing " normal " distribution a whole nother way, not comparable to the " 100% " or the " 40% " . [you said:] > Many people who respond positively to HBOT also respond positively to just breathing straight oxygen through a mask, which is far easier and cheaper to arrange. Also one can REALLY get things going by doing exercise while breathing it through a mask so as to turn up the metabolism while extra oxygen is available. That may be -- anything you would recommend reading that points to this? Obviously studies of HBOT can't be used to figure this out. And the specific case of the child who was being discussed here was use of both pressure and [higher levels of] oxygen. (People generally say " pure oxygen " even though the levels used vary, in part depending on type of mask, etc.) [i said:] > > My addition to the conversation, which I hope may be useful for > > those trying to understand HBOT (and/or trying to make sense of > > what you said) is that HBOT generally refers to using more > > oxygen AND being under more pressure. EACH OF THEM results in > > more oxygen being available -- and BOTH TOGETHER is much more > > effective than either alone. [you said:] > This is not correct and is the part of the sales pitch " HBOT salesmen " may use that could either be characterized as wilfully and negligently ignorant, or as fraudulent, depending on whether the salesman has any real technical knowledge. However without adequate technical knowledge on the part of the listener it is easy to get drawn into this. And, which part did you think was so deeply misleading? Perhaps you object to my use of " more effective " since there may be individuals for whom oxygen would have been effective? Even if that is true, HBOT (oxygen + pressure) is still a more effective way to distribute oxygen, and it is extremely likely that many people who benefit would NOT (similarly) benefit from oxygen alone. Which means that I think " more effective " is accurate, even though I don't mean that every individual will benefit from HBOT or that HBOT is " more effective " than breathing oxygen at normal pressure for changing some condition in some person or for improving all conditions or any other specific thing. I would guess that for most of the things that HBOT is generally accepted as useful that there's not adequate information to say to what degree [normal pressure + oxygen] would help -- and thus (I would guess) that there is no way to quantify how many of the people who are helped by HBOT that could have been helped by " just " breathing pure oxygen (without pressure). I'm sure you have some reason for saying it is " many " who are helped by HBOT who WOULD have been helped by oxygen w/o pressure. In most cases people don't use these therapies in ways that lead to any hope of concluding whether oxygen at normal pressure would have worked -- the limitations of life not providing a control group, let alone control groups for each variable.

This is generally a true statement in all fields of research on everything. This is why a lot of the 'playing gin rummy with pubmed abstracts' that goes on is so silly. This is why there are 2 key things to pay attention to - the people doing the study (are they generally ethical in reporting as best they can what happened when you look at the sum total of their work, and are they generally competent in actually getting the right answer), and whether the study hangs together in light of generally well known OTHER science that is well enough accepted that the politics has probably been massaged out of it by now.

In the case of HBOT, Rossignol has probably done some decent first-cut studies. One of the reasons that I trust them is that though he obviously wanted to show gains, he couldn't because he listened to his data. The placebo effects were huge, and that's a big warning sign to me for all parent reported data for ASD treatments. Still, I'm willing to keep an open mind to see if he (or others) can find something further on. There are plenty of positive parent reported effects for HBOT in forums though... are they all wrong?? I can't say. By that same standard though, (as you know), it worries me that there aren't any ALA or ALA+DMSA studies based on your protocol that are close to happening. [Probably due to the Strupp and Aposhian results.] We seem to have no good idea of the placebo effects or potential detriments to this approach. Why we can't find *one* good, capable body and petition/push them to do such a study is beyond me, and it gives me great pause when people suggest that there's no value in that ... I'm no expert, but the latter just doesn't strike me as science.... and I don't see how it offers a way forward to further improving treatment for our kids and those that follow. Also, w/o at least some studies to draw on, you couldn't have pulled together what you did that seems to be helping many adults and kids with metals issues. Why then are studies now seen as useless to confirm that what we're doing is universally good for our kids? Quote Link to comment Share on other sites More sharing options...

Guest guest Posted March 31, 2009 Report Share Posted March 31, 2009 Hi mildcasedad, You may be interested to know that there was a study PLANNED at one time that would have included [something in the general neighborhood of Andy's protocol -- at least the dose timing] and [something more like DAN's dose timing]. I don't remember much else -- but then, I think many of the details were not really announced, I don't recall how much detail was included... little bits of it still come back though as I think about it. This was several years ago -- maybe about 2001 or so?? And the whole thing got scrapped. best, Moria > > > > > In the case of HBOT, I expect there is precious little money > > > from any " independent " source. > > > > This is generally a true statement in all fields of research on everything. > > > > This is why a lot of the 'playing gin rummy with pubmed abstracts' that goes on is so silly. > > > > This is why there are 2 key things to pay attention to - the people doing the study (are they generally ethical in reporting as best they can what happened when you look at the sum total of their work, and are they generally competent in actually getting the right answer), and whether the study hangs together in light of generally well known OTHER science that is well enough accepted that the politics has probably been massaged out of it by now. > > In the case of HBOT, Rossignol has probably done some decent first-cut studies.

Guest guest Posted April 1, 2009 Report Share Posted April 1, 2009 After all these years id like to say, still have a lot of respect for the veterans for hanging in there. Mostly guys like Andy. Sticking around too, putting up with trollish behaviors. At best continuing to answer the Q's regardless of the validity of the confrontation. I'm forever grateful in what he has said, warned and cautioned against. …….. Mostly correcting the dangerous advice etc… I think we are all grateful to be able to come at least to this forum and hear constructive debates. (Possibly hear the other side to a story.) IMO Topics like this we can always learn from In fact if it's done with respect in all honesty. Again .If it wasn't for this group (which taught me to become an independent thinker) … IM not sure where kiddo would be today. Anyway for many years I have relied not only on some of the info of these groups but also much of parental testimony. But today I'm not sure of that. Guess we still have to separate the " wheat " from the " chaff " as with all info. Now we need more to use more discernment. In EVERYTHING we read. On these groups Either that is the pattern lately of finally my eyes have been opened after reading diligently for over 8 years. Today id say. Don't believe every thing you READ /hear and mostly posted on these boards. HALF of it is NOT true the other half MAY be true. But that you CANT validate either can ya? So where does that leave us all? Just like the 50% who do not get better and get worse, as there is no merit in with that statement either. So where does that leave us again ? Maybe another thread like this one that was prob was a set up from the get go . Who knows these are all old arguments aren't they. Let me know when you have the " real " answer. Did ya ever notice the parents who comment about all the negative effects and all the regressions are in fact ones who have never done the therapy? Did ya ever notice lots of parents who desperately need help for a friend leads to some crazy thread like this one? Bottom line. Some of the stuff is true some of the stuff is the farthest from the truth. Some of the parents are real parents with autistic children But some posts are from a psychotic individual that has nothing other to do than make you read all their garbage, cause division, debunk biomed and keep the same old controversial subjects flamed kindled. IMO do your research make and educated choice but The ONLY way you know what is true or not is to see it with your own eyes.

Guest guest Posted April 1, 2009 Report Share Posted April 1, 2009 Hi Moria, As a diver, I can confirm that what Andy says is considered true from an _oxygen_ _delivery_ standpoint.... [Trying to keep this simple.... Partial Pressure is not the same thing as the atmospheric pressure that the hbot tanks provide, but rather the pressures of the different components of a gas (e.g. air) in a liquid (i.e. blood) at the local level, esp. when under water/pressure for divers. What Andy's talking is what physicists and divers call Dalton's law.. http://en.wikipedia.org/wiki/Dalton%27s_law_of_partial_pressure and http://en.wikipedia.org/wiki/Diving_physics#Laws_of_physics_for_diving In brief ... " Dalton's law - in mixtures of breathing gases the concentration of the individual components of the gas mix is measured by partial pressure[2]. Partial pressure is a useful measure for expressing limits for avoiding nitrogen narcosis and oxygen toxicity. " The latter happens when too much oxygen is being delivered... that's what all that is really about.] You _can_ get the same oxygen delivery effects as HBOT from breathing a different mix of gas (at 1 ATM == sea-level with no HBOT tank) with more oxygen in it than the 21% that air has and for a few hours (in adults). Even higher oxygen percentages are pretty safe. Getting tanks with air or different gas mixes is likely a bit trickier than getting an HBOT chamber, and that's my guess as to why that isn't being done more. Dive shops aren't even supposed to give you compressed air w/o seeing your diving license, and more certification is required for higher oxygen mixes. Medical oxygen delivery companies might be of more help, but I'd guess they're similarly restricted (but might bend the rules or not be as strict in checking??). [it's also possible mix oxygen gases yourself but that takes a bit of work, knowledge, and lots of safety.] Hyperbaric chambers were normally used to help get the gas bubbles out of divers by using the pressure to shrink them if possible (after pretty serious accidents), and nothing more.... Of course, the other thing that hyperbaric chambers do that a simple tank and (diving) regulator won't is provide more atmospheric pressure that compresses body parts (just like a cat sitting on your stomach). Offhand, I can't see the brain being as influenced by pressure since it's encased in the skull, but the rest of the body doesn't have that. Most of what I see being talked about by Neubrander, Rossignol, etc are the positive effects of _oxygen_ using HBOT. Though the effects of oxygen on the body are much better understood that those of _pressure_, it is possible that the pressure is also helping in ways that aren't as well known. To my current understanding, benefits from pressure rather than oxygen content are probably more conjecture at this point. When we considered HBOT, we didn't see many effects that chelation/biomed improvement wouldn't probably address eventually, and many reports of HBOT effects seemed to be temporary ones to us. Still there are plenty of reports from forums and friends that suggest benefits and are hard to dismiss. [You only hope that those aren't the strong placebo affects seen by Rossignol in his HBOT studies, but that's true of every ASD treatment and nearly all of our " research " is just based on parent reports which aren't fully reliable.] I have an pretty open mind about HBOT, but given the above it hasn't made it to the top of our list according to our own cost/benefit analysis. Your mileage may vary. Best wishes. > > Hi Andy, > > Well, this is interesting, since I read your comments as > mostly saying what I said. > > [i said:] > > > Pressure alone results in oxygen being distributed in the body > > > much better.

The child had a grand mal seizure at 20 treatments and required hospitalization - the little child even broke a tooth. > > --penumbra > Quote Link to comment Share on other sites More sharing options...
