Guest guest Posted September 5, 2003 Report Share Posted September 5, 2003 , I will try to do a little more work on this next week. But, remember, O2 toxicity cannot be calc'd by number of treatments at the clinic. It comes about as patients obtain more sessions with more O2, and their own predispositions. Thus, you can give 8000 treatments by giving 40 treatments to 200 patients and it really would not mean much. If the 8000 came about by giving 200 treatments to 40 patients, then that is a relevant track record. I am personally certain it exists though. had an issue with it once before and I have been cautious ever since.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 Yes O2 toxicity is very possible. After about 50 treatments the first time Kaltyn began to get very agitated as I have said on here several times. I didn't realize at the time and continued to 72 treatments at this time she was so agitated that we were not getting sleep. Now we didn't understand she was so much better and we were so happy we over looked the obvious. She was getting sick from to much. It wasn't till we got her home about 10 to 15 day's into it she began to calm down and our lives was outstanding. This has been the case with many. I know another parent that takes her child for HBOT now she goes for a block of 40 but if at any time the child becomes severely agitated she stops takes the child home waits several months and starts back up.I have a chamber here at home and I don't treat her everyday. I have found that 5 to 20 treatments every 2 months is better for her. We usally get about 20 to 25 every 2 months hope this help's.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 Ed, many of our clients have now had over 150 sessions without any problems and some have had over 300 (not all here, of course). We always require a break between series of treatments. We need to make certain we know what toxicity is. There is a major difference between toxicity and sensitivity. thanks Hartsoe www.miraclemountain.org Re: [MedicaidforHDOT] hbot toxicity > , > > I will try to do a little more work on this next week.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 Darin, Agitation is not just a sign or indication of Oxygen Toxicity. If it were half of the kids would not be treated with hbot. It is a sign of stress and exhaustion and being aggravated at having to continue to go through the same routine. They learn very fast how to get response. We need to keep our definitions clear. It takes a much clearer combination of symptoms to diagnose Oxygen toxicity. That is what technicians and medical professionals in hyperbarics are trained for. In one 20 year study report by EC & Myers RAM (Undersea Biomedical Res. 19 (Suppl.):109) central nervous system oxygen toxicity (0.7%) occurred ONLY in critically ill patients who were unconscious and ventilator dependent. I cannot find any discussion of the existance of toxicity at treatments under 2 ata and, in fact, most texts refer to the possibility of it happening at treatments over 2 ata. I think parents have enough to worry about without fears being instilled into them which do not exist. If there are sensitivity issues which I have not seen to my knowledge, parents will probably recognize them. And Oxygen toxicity is not a permanent or lasting effect. Oxygen sensitivity or tolerance can be affected by certain issues, such as drugs or certain high hormone levels (Adrenocortical) and can even be a sign of CO2 inhalation which is one of my concerns with in home use of chambers. Insulin as well as a deficiency in Vit. E can also increase sensitivity levels. I just recieved a report of another facility stating clearly they have never seen a case of toxicity in treating below 2 ata. And they do a large number of children with brain injury. That is the reason I am asking for comments and reports from HBOT facilities. It needs to be from a trained eye and not be mistaken as toxicity when it is probably some of the other related issues including stress, agitation, etc. Hartsoe www.miraclemountain.org Re: [MedicaidforHDOT] hbot toxicity > Yes O2 toxicity is very possible.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 , I think you hit one of the key issues - good breaks. Also (speculating) maybe your " mountain air " gives them better recuperation because it is a higher altitude?! One more reason for families to visit your center. Personally, I still disagree on the symantics of sensitivity and toxicity...... not withstanding all of Dr. Foijels efforts to educate me (see my last post on that subject several months ago.) Either way (tox. / sens.) something physiologically negative is going on for that patient in response to HBOT without enough rest. On the extreme side O2 toxicity is well illustrated at the metabolic and subcellular level in Jain's textbook in cases where normal patients are given O2 at very high pressures for extended sessions.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 Actually it is my understanding that agitation is the first sign of toxicity. My daughter has gotten to that point with too many treatments, in her first block. Her other symptoms were pale skin, moody, tired and she told me an upset stomach. How many kids can communicate these symptoms? We really backed off and are now doing more then a few months between. It is something for parents to be really be concerned with. My daughter lost weight too, and this was upsetting. As far as symptoms go, it really is the parents who know the child well who will be able to spot these negative changes. As an example, so many people say my daughter looks tired. Well they have no idea she always looks tired because of low tone. I am the one who can judge true exhaustion or tell the difference between being overwhelmed sensory wise, or lack of sleep, etc. So until there is something definitive, I would trust parents input much more then an operator who has no history with the child and spends a few minutes a day observing. So what exactly are the symptoms of oxygen toxicity, other then what I have described above? I am curious to know...thanks >Darin, >Agitation is not just a sign or indication of Oxygen Toxicity. If it were >half of the kids would not be treated with hbot. It is a sign of stress and >exhaustion and being aggravated at having to continue to go through the same >routine.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 I am confused too. I thought that air nearer sea level (we are in FL) contained more oxygen than air in higher elevations, such as the Rocky Mtns. Wouldn't it be better to recuperate at an elevation at sea level, with higher oxygen levels? Sheri, Rex's mom.

Guest guest Posted September 6, 2003 Report Share Posted September 6, 2003 Sheri, Again, this is only speculation, but if the issue of O2 sensitvity / toxicity is the effects of too much O2...... then the solution could be to more rapidly deplete the system of the excess O2 and let it readjust. Being at a higher altitude could possibly accomplish that better than sea level. Note this is only logical metabolic speculation. I know of no studies or research on these specifics.

Guest guest Posted September 7, 2003 Report Share Posted September 7, 2003 Greetings, The ocean waves and the winds create ozone, the natural oxygenation of the earth. And in the mountains esp. where is have a saturation of it because instead of being dry, as it is out west in the Sierras and Rockies, they are full of condensation. The western mountains are dryer because of their higher altitude and distance from the ocean. If you go to the Ozarks in AR and MO you see and experience the same thing. That's just a novice explanation of the effect. I'm sure there is someone out there that will use scientific explanations for it. Dr. , are you out there?

Guest guest Posted September 8, 2003 Report Share Posted September 8, 2003 We are fast approaching 750 treatments. We try not to go out of town for more than a couple of days at a time as we find if we miss too many it is like starting over. To make this clearer; it takes Eddie about 32 treatments to show improvement, therefore, every time we take a break we see nothing for 32 or more days. We try never to break for more than 3 days at a time at the most. He has never showed any signs of toxicity. Yes, he gets agitated, mad, cranky, doesn't always sleep well, gets colds, and gets sick, He's a kid. All I know is that the more we do the better he gets. And better is my goal. If we stopped now I am sure he would stay the way he is. It's not good enough and he gets older everyday. Time is my emeny. We also did 350 in a row (meaning no breaks) with my 3 year old nephew and he showed no signs of toxicity. In fact, he is completely well. Stay below 1.75. Love to all, Rose [MedicaidforHDOT] hbot toxicity > This is to any and all hyperbaric facilities who treat brain injury at 1.75 ata or below. Can you document a single case of oxygen toxicity at these pressures. Dr. Harch makes claims of oxygen toxicity. We have done almost 9000 treatments since April 2003 without a single case. There may have been a possibility of an issue to oxygen sensitivity but I don't think so. In the beginning when we were treating 7 days a week, stress and exhaustion created some problems but after we went to 6 days with a more relaxful atmosphere, it was no longer a problem. > > I would like to hear your comments.

Oxygen toxicity can be a serious issue and should not be used to scare people unless it can be documented. If it can be documented at these low pressures we need to do so and let the consumer know with proper advice on what to do. Protocols need to be changed to once a day or whatever it takes.

Guest guest Posted September 8, 2003 Report Share Posted September 8, 2003 While I know that is asking for info regarding treatment at 2 ata or less, this discussion brings to mind a question I've had for some time but never had answered. It is my understanding that in acute situations such as carbon monoxide poisoning or a diving accident, individuals can be treated at signficantly higher pressures than 2 ata and for fairly extended periods of time. Do these individuals exhibit toxicity issues? It would seem to me that if there is any concern that toxicity can develop at less than 2 ata, then it would be a really serious concern in acute situations. OTOH, perhaps it is more important that the poisoning or whatever condition be treated, even if there are risks of toxicity. Perhaps the possibility of toxicity is the lesser of the evils? If someone can shed light on this for me, I'd appreciate it. Lynn > > > >This is to any and all hyperbaric facilities who treat brain injury at > > > >1.75 ata or below.

Guest guest Posted September 8, 2003 Report Share Posted September 8, 2003 While toxicity can take place in anyone and at any pressure, the general rule of thumb is that patients that have had to adapt to low oxygen tensions over time, such as individuals with COPD or Sickle Cell Disease, are much more likely to have toxicity issues than the average man on the street.

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Dear friends, Dr Harch is talking about the fact that Hyperbaric Oxygen is an immune suppressant as well as an immune enhancement, Doing HBOT twice daily for certain people can at a certain number ( upper end) cause the patient to have a little free Radical activity, and therefore some people develop a cold, that is why you need to watch children., If towards the end of the 40 they become lethargic or have a running nose, you need to take a couple of days off, then resume. Here is what I usually do, I give patients Sunday and weds off, and if they have a time frame that they must return home or a limited amount of time. We will do two on Saturday, then a full 24 hours off on Sunday, One on Monday, Two on Tuesday and a full 24 hours off on Weds, One on Thursday, one on Friday, then two on Saturday and so on..... I arrange it to fit the needs of the people because no two patients are alike as you well know, However in the last ten years I have never had even a hint of a problem. there again we have them take a vitamin E after the last treatment of the day. I watch carefully, not to mistake this for a personality change. Quote Link to comment Share on other sites More sharing options...

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Dear : It was most helpful for you to write what you are doing with the protocols for your patients. It is so important to get and to keep and open and candid dialogue on the protocols for HBOT. Both on the national level and at the international level. I have tried without success to find out what the military research has been regarding the milder portable chambers. I was told last week that the Navy has put in an order for 53 of the hyperlites madein the U.K. It would be ever so helpful if we could get the international hyperbaric community to exchange info on what their research is finding. Perhaps the two associations will turn up some of the findings from the international as well as the national community in all types of chambers. Meanwhile thanks for all the valuable info you posted on the subject of toxicity or lack of it with respect to your own experience.

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Yes and no, we have a 54 " dual lock, multi place chamber made of steel. As far as O2 is concerned, my son's doctor is wonderful. He is amazed and impressed with his improvement and therefore supports us fully. (gives us a script). We use liquid medical grade O2 because it cost less. We compress with air and breath O2 via hood or mask. Both my husband and myself went to Hyperbarics International in Key Largo, Fl to be trained.

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Dear Ed, two months ago you ended a posting with these words: > Personally, I feel sensitivity is a better term, because we are only > discussing this in a safe therapeutic range. But, everyone in HBOT > discusses it as toxicity, so I use their language. > > Maybe this is one bad habit I can break! > We tried to refine this discussion, but to little avail, it seems... Let's tackle it again: There is overdose and there is sensitivity, -two different entities-, that may coexist. 'Overdose' is an excessive dose or too many doses ( a function of mass and biochemical work), while 'sensitivity' denotes the exquisite reactivity of an injured biological system to an otherwise innocuous dose of a substance (a bio-pathological reaction of the body). Does overdose happen in the correct hyperbaric protocol for a chronic neurological conditions? No, by definition. May sensitivity appear there? Yes, as injuries or their scars or effects may subsist for years, and eventual unrelated diseases or untoward metabolic incidents may complicate the scenario. Does sensitivity occur in the acute neurological patient? It usually does. Sensitivity is a sign of impairment of the defence mechanisms against hyperoxia, or some exaggerated vasoconstrictive reaction, as Dr. explained. The blood-brain barrier, a function of the glia, is also involved. Care should be exerted to differenciate those sensitivity symptoms from tiredness, excitment, or from developments of the basic condition. We are dealing with complex, auto-regulative, semi-open systems. As the distribution and metabolization of oxygen is dependent on several factors (temperature, pressure, local vasodilatation, blood rheology, target organ, oxygen use at cellular levels, autonomic nervous regulation etc.), and its level of availability ultimately regulates them, it may not be easy to accurately adscribe symptoms without taking those factors into account. 'Toxicity' applies to the effects of substances poisonous at a usual dose. Oxygen is not such a substance. Oxygen toxicity is both an unfortunate and illegitimate term. Gerschman (from Argentina) was the first scientist to propose that free radical intermediates (superoxide anions, hydrogen peroxide, hydroperoxy and hydroxyl radicals, and singlet oxygen) were responsible for the so-called oxygen toxicity, during excessive exposure, -in terms of pressure/ O2 concentration and time-, specially if the anti-ROS protective mechanisms are impaired (SOD, catalase, etc.). It should be taken into account that hypoxia will also generate deleterious free radicals, where a generous but graduated supply of oxygen will be the cure. Although clinical hyperbaric oxygen dosage is always a relatively high dose, comparing to natural conditions, a healthy, auto-regulating body can take it without problems, within empyrically established limits. Tired, hungry, ill, stressed, intoxicated, inflammed, edematose or otherwise affected patients cannot be deemed healthy, though. Shorter courses, lower frequency, and breaks may be necessary, as oxygen may elicit side-effects in sensitive, pre-affected individuals. Brain injured persons display these effects much earlier, at lower levels, meeker pressures, diminished concentrations, and if oftenness were excessive. With all due respect, recourse to the authority of a single distiguished practitioner, or a decontextualized quotation from a book will not take us any further. Only the acknowledgment of the factors at work could prompt us to foresee any side effect, and to correct an erroneous dosage, before it provokes any damage. Another problem may be the difficulty of identifying overdose symptoms in a stable condition that becomes dynamic as a result of treatment, or that dwindles as a result of coexistent conditions, lack of rest, stress, etc.. It may not be easy to differenciate a symptom from a result, or a result from a natural development, either. Mountain air is scant in oxygen and other gases. Gauge pressure/oxygen concentration must be corrected for the lower barometric pressure. Several days at altitude elicit an increase in red blood cells count, and other acclimatization mechanisms, that may last for several weeks. Hyper and hypobarics may be concurrent to the same end, for disparate reasons, but it depends on the occasion. How high are you located, ? Moderate altitudes can modify some therapeutic effects. " Rehabilitation of hypoxemic patients with COPD at low altitude at the Dead Sea, the lowest place on earth " MR Kramer, C Springer, N Berkman, M Glazer, M Bublil, E Bar-Yishay and S Godfrey Pulmonary Institute, Hadassah University Hospital, Ein Kerem, Hebrew University, Jerusalem, Israel. The discussion may be meaningless, if all known variables are not quantified and seriously taken into account. German research has established 1.5 ATA/100% as the optimal neurological dose, and a Russian school advocates much less (1.2ATA/30%/30 min/qd/4 sessions), if the patient has been brain injured in any way. They use several paraclinical parameters to assess treatment outcomes. Best regards, as always. Ignacio Ignacio FOJGEL, m.d.

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Dear Lynn, brain injuries impair the blood brain barrier, and the vascular and tissue protective mechanisms against oxidative effects. Carbon monoxide can damage CNS organs and structures, induce coma, etc.. In this scenario, excessive oxygen cannot but damage further. Spasticity ensues more rapidly after high pressures and concentrations, and degradations of the condition are more difficult to treat or become fixed. Certain symptoms are expected in any brain injury, and some of those can be confused with the ensuing oxygen sensitivity (some people call it toxicity, blaming innocent oxygen...). Monoxide is considered the main foe, and free radical damage by excess oxygen is not given the proper attention, so USN Table 5 is usual protocol. You are right: individuals can be, -and are- thus treated, but should they? I do not believe it conducive to an optimal treatment. Best regards.

Guest guest Posted September 9, 2003 Report Share Posted September 9, 2003 Dear , Chronic Altitude Sickness is another model for your concept. Those chronic patients show free radicals damage from hypoxia. CAS adds reactive polycytemia and blood hyperviscocity, etc.. Nonetheless, acute carbon monoxide intoxication with CNS injury, as any other acute brain injury, is excedingly more likely to have those issues.
