Chronic Hyperventilation Syndrome and Jennifer's asthma
Question:
The outrageous allegations made by CBI on this news group, suggesting that I am deliberately trying to deceive the readers on this group are patently false and clearly intended to discredit the Buteyko movement of which I am a vocal advocate. not at all Peter…they are patently true and given even more proof by your own misleading post, whether mistaken or dishonest…I still haven’t made up my mind whether you are a fool or a fraud…
My impression is the latter. I think he has let fervent believe and hope cloud his judgement. – Hide quoted text — Show quoted text – From Sher, assistant clinical professor of medicine and pediatrics, Case Western reserve school of medicine. Cleveland , Ohio (Ref 2:) " The acute form of HVS, which represents 1% of patients with the syndrome, is readily diagnosed because of its characteristic presentation, including carpopedal spasm, extreme anxiety, impressive hyperpnea, tetany and parasthesias. The chronic form may present with bizarre and often unrelated symptoms that may affect any organ system. The prevalence is reported between 6% to 11% depending on the patient population." [And just in case you are speed reading Chris, 1% of HVS is ACUTE and that means 99% is CHRONIC] would the chronic form be somebody who has chronic episodes of acute hyperventilation?…that’s how it reads to me…in other words there are three options ordinary HVS, acute HVS and chronic acute HVS…the latter being somebody who has acute HVS frequently…it doesn’t seem to imply the existence of a low level chronic HVS at all
Exactly my interpretation. — CBI, M.D.

I have asthma and my name is Jennifer. How can I learn more about HVS

– Hide quoted text — Show quoted text – The outrageous allegations made by CBI on this news group, suggesting that I am deliberately trying to deceive the readers on this group are patently false and clearly intended to discredit the Buteyko movement of which I am a vocal advocate. The dishonesty he has demonstrated is all the more despicable considering that doctors automatically have a credibility advantage by virtue of their position. He has blatantly abused that position and I’m now going to expose it. Chris knows full well that the average reader on this news group is not going to check on the references, but will simply take his word for it, because after all he is a doctor and people expect doctors to be honest. It makes them feel insecure to think they can’t trust their doctor. I have used the medical literature to make specific points to demonstrate that Buteyko’s theory has a basis in medical literature. But I have no doubt that even the hyperventilationists would be surprised at the results achievable with Buteyko’s treatment. I’m sure none of them would have expected that asthma could be reversed by reversing chronic hyperventilation as universally as the anecdotal evidence suggests. At the center of our dispute is the question of whether or not chronic hyperventilation syndrome actually exists in the community. My position has consistently been as follows: 1. The condition does exist in the community 2. It is associated with a large number of bizarre symptoms 3. It is very poorly understood by most of the medical community 4. The anecdotal evidence brought about by Buteyko’s treatment supported by the Brisbane clinical trial findings suggest that even the small section of the medical community who understand the disorder have understated its significance. CBI contends that chronic hyperventilation does not even exist and that I have deliberately misrepresented the literature. He recognises only that the acute form of the disorder exists and can trigger asthma attacks.
At least he has finally stopped misquoting me. To follow the ensuing argument it is importent to realize that for a long time there has been a hyperventilation syndrome known in psychiatry. It is a form of panic attack. It used to be considered that it was always acute and self limiting. The old fashioned treatment was to breath into a paper bag. More recently people have come to understand that while the respiratory component is acute and short lived the effects of the anxiety disorder can persist and cause longer lasting symptoms, hence the term chronic hyperventilation syndrome. There is no data to suggest that the respiratory component is chronically abnormal. It has nothing to do with the coincidentally (?) named disorder sited by Buteyko supporters. I’m now going to quote *verbatim* from the literature, most of which I have been referencing for a very long time. I will omit Nixon’s very substantial and outstanding contribution.
For good reason. Everytime you reference him someone brings up the rather annoying fact that he has been exposed as a fraud. From Cluff (Ref 1): "Hyperventilation or (over breathing) is a perfectly normal reaction to stress, and a large proportion of people have at some time experienced some of its effects, eg. the racing heart, weak knees and ‘butterflies’ in the stomach so often felt before examinations. But these symptoms normally disappear once the stressful situation is over".
Did you read the part about the symptoms being related to acute episodes of stress, not chronic? I would also point out that the referenced article is a "discussion paper," i.e. no new data presented. Ruff does not appear to have any other publications indexed on medline on any topic . "Between one-half and two thirds of patients over breathe consistently, so that the PCO2 is continuously below the normal range (36-44mmHg = 4.8-6.0 kPa), a condition of respiratory alkalosis, or hypocarbia." [Did you pick up on that Chris? The word is *consistently*]
He said consistently, i.e. every time they have an acute episode of stress. He has said nothing about the chronic baseline state. Since the paper is not an original research paper it might be interesting to know what he was quoting and look at the original data. Since it was published before 1984 I doubt the data shows chronically lowered pCO2’s or you would have brought it up by now. From Sher, assistant clinical professor of medicine and pediatrics, Case Western reserve school of medicine. Cleveland , Ohio (Ref 2:) " The acute form of HVS, which represents 1% of patients with the syndrome, is readily diagnosed because of its characteristic presentation, including carpopedal spasm, extreme anxiety, impressive hyperpnea, tetany and parasthesias. The chronic form may present with bizarre and often unrelated symptoms that may affect any organ system. The prevalence is reported between 6% to 11% depending on the patient population." [And just in case you are speed reading Chris, 1% of HVS is ACUTE and that means 99% is CHRONIC]
Yes, but by HVS he means anxiety. When he refers to chronic HVS he is refering to chronic anxiety and the seemingly unrelated somatic complaints that can accompany it. Even if you dispute what the author meant, he still has not presented data supporting chronic hypeventilation. Again, you are confusing psychiatric terms with physiologic ones. "Hyperventilation is known to cause asthma and may further reinforce symptoms of HVS. In such a setting HVS and asthma may feed back upon themselves"
Translation: Panic/anxiety and exersize can trigger asthma. Still no data on respiration. "Hyperventilation syndrome (HVS) is a fairly common and occasionally disabling condition that in its chronic form may be extremely difficult to diagnose." "In summary, HVS is a common though often unrecognised disorder" [Note, Chris, Chronic Hyperventilation is often unrecognized!!!!!!!]
No, Chronic hyperventialtion syndrome, which in the psychiatric literature refers to chronically recurring episodes of panic, is often missed. Still no data on respiration. Here’s one I haven’t used before from Malmberg: (Ref 3) "When hyperventilation occurs chronically or in recurrent episodes and is associated with somatic (respiratory, neurological, intestinal) or psychological (anxiety) symptoms, the clinical entity is called hyperventilation syndrome (HVS)" [Note Chris, only when it is chronic or recurrent is it called HVS] "The correct diagnosis of HVS is of great clinical importance since at least 5-10% of general medical outpatients have been reported to suffer from this syndrome and, due to a variety of somatic symptoms, the risks of misdiagnosis are considered to be high."
This is the start of the referenced article. "BACKGROUNDHyperventilation syndrome (HVS) is a common disorder which is difficult to diagnose because of somatic symptoms and its episodic nature. In previous studies respiratory alkalosis in arterial blood was often found during orthostatic tests in patients with HVS. The purpose of this study was to assess these orthostatic changes by non-invasive pulmonary gas exchange measurements and to evaluate whether these responses discriminate patients with HVS from healthy subjects." You will note that the author states the disorder is episodic, i.e. not chronic. This was a study to see if they could provoke hyperventilation by inducing orthostatic changes in susceptible people. It is also noted that before the provocation, while at rest, the parameters were the same between the two groups. In other words, there are only acute differences during the test, there were no differences at other times. Please accept this as one of the requested examples of literature you have intentionally misrepresented. You quoted a passage about CHVS and stated that it supports your contentions when, in fact, the author clearly states that the measurable abnormalities (overbreathing) are episodic. Or did you just not read it carefully? And Gardner: (Ref. 4) "Hyperventilation is a confused and poorly documented subject and the publication of this paper provides an opportunity to review some of the particularly controversial aspects of this subject." [The whole paper deals with just how confused the subject is]
This is an editorial in the same issue of Thorax as ref #3. There is no abstract and I have no access without paying $25 or going to the library at the hospital, which I am not committed enough to this argument to do. The quote you have given does not make any statement one way or the other. You don’t really expect me to just take your word for it do you? – Hide quoted text — Show quoted text – And here, once again, is the list of symptoms that have been attributed to Hyperventilation Syndrome. This time I have not referred to Nixon’s papers and indicated precisely which reference the information was derived from. Incidentally, Professor Nixon has had papers published long after the notorious court case. He is obviously still being taken seriously.

if anyone finds Peter Kold at all convincing but has so far not bothered to check the arguments in detail, please try to find the time and concentration to go through the whole of this post…I’ve tried as far as I am able to explain why his use of medical references is misleading…I’ve tried to steer clear of jargon The outrageous allegations made by CBI on this news group, suggesting that I am deliberately trying to deceive the readers on this group are patently false and clearly intended to discredit the Buteyko movement of which I am a vocal advocate.
not at all Peter…they are patently true and given even more proof by your own misleading post, whether mistaken or dishonest…I still haven’t made up my mind whether you are a fool or a fraud…but given the number of times you have contradicted yourself, the number of times that you have totally misinterpreted medical references, and the number of times you have quoted selectively out of context, the one thing certain is that you are NOT telling the truth The dishonesty he has demonstrated is all the more despicable considering that doctors automatically have a credibility advantage by virtue of their position. He has blatantly abused that position and I
