Guest guest Posted May 7, 2003 Report Share Posted May 7, 2003 To complement your post on the Partial Pressure issue, I accept that you are correct in the sense that in order to obtain an exact absolute figure it is necessary to take into account the partial pressure of water vapor and the partial pressure of the exhaled Carbon Dioxide. And the complete and long formula you posted is correct too, but that really is good and useful only for academic discussions. For a common non technical person,as a parent looking for a solution for his kid,in general we could say, it is even very difficult, not to say impossible, to resolve that formula. What really I have expressed always ( and maybe it is my fault that I did not clear my point of view ) is that I work with the Oxygen partial pressure in the atmosphere inside the chamber, it is easier to calculate and understand. Remember what Einstein said a long time ago: & #8220;everything is relative, all depends on which side is the observer & #8220; For a parent is easier to understand the relative increase in Oxygen partial pressure, from plain air to the Oxygen enriched environment inside the chamber. So on the long both of us were correct, we just & #8220;were observers on different sides of the issue & #8220;, and the real fact is that the Oxyhealth or any type of Gamow chamber, works, and works well, it is just plain high school physics. Any way , any increase in applied pressure or concentration of Oxygen inside the Chamber, will result in an increase of the real final alveolar partial pressure ( whatever it will be, it does not matter ), and also at the end of the Oxygen cascade inside the body when the Oxygen reaches the mitochondria at cell level ( really the final burners of the Oxygen ) it will be increased too, as Dr. from England and Dr. Ignacio Fojgel from Argentina explained so well on their posts,. and a & #8220;small increase of 50% in the plasma Oxygen concentration is a very significant increase & #8220; not to say of a 600% increase. And that is the real reason why the Oxyhealth low pressure chambers, or similar, are showing positive results, as in the McGill CP study, and as Dr. Fojgel said & #8220; a repeated minute increase of cellular oxygen ( twenty sessions at l.3 ATA with plain air ), over the threshold may be a better explanation & #8220; of the results, not & #8220;the excitement of parents and patients may have been only a microscopic fraction of the cause & #8220;. I have been able to see along my twelve years of direct HDO experience, many times unbelievable results with small increases of pressure as low as twelve ( 12 ) inches of water column, that translated to PSI means an increase of pressure of less than one third of a pound per square inch. The most probably is that you will not believe that, but that is a real fact and the real truth. If you want to come some time down here and convince yourself, you will be able to appreciate direct and objectively how the body reacts to very small increases of applied pressure. Maybe as Dr. Fojgel said in one of his posts several days ago: & #8220; the fact that 1.3 ( ATA ) of plain air has been shown to be active treatment, and not placebo at all, should put all us to re-think our concepts, and perhaps lower our pressures. The best treatment should be the minimal active pressure for the specific condition. & #8220; Sincerely, Arturo ez-Restrepo, M.H. e-mail: < armarlife @hotmail.com > Quote Link to comment Share on other sites More sharing options...
