Clinical Trials of Buteyko Respiration Technique for Asthma

Breathing techniques and respiration devices become more and more popular among asthmatics and people with other respiratory problems. Among the known breathing techniques is the Buteyko breathing method, which had six randomised controlled trials in western countries.

The results were remarkable: twice less steroids, 3-10 times less reliever medication, better quality of life and less asthma symptoms, but unchanged bronchial responsiveness or lung function results after several months of breathing exercises. Meanwhile, all these studies had a major methodological flaw, which I am going to consider here.

Dr. K. Buteyko made the following clinical statements:
– Sick people, asthmatics including, breathe more air at rest than the minuscule medical norm (chronic hyperventilation). Overbreathing reduces tissue oxygenation and strengthens the desire to breathe even more.
– If they normalize their breathing pattern, then they will not require medication and will not experience their symptoms.
– The Buteyko Table of Health Zones relates breathing parameters of sick people, regardless of the name of the disease, with their current health state. This table describes parameters that reflect normal breathing (8 breaths/min for breathing frequency at rest, 6.5 percent for alveolar CO2 content, 60 seconds for stress-free breath holding time after usual exhalation, etc.). These parameters correspond to normal health and absence of asthma and many other chronic diseases since normal breathing improves body oxygenation.
– Someone has mastered the Buteyko breathing method, if his breathing parameters are normal.

Dr KP Buteyko never made claims that a particular Buteyko practitioner could achieve a particular result in relation to some group of asthmatics. Let us apply these Buteykos claims to available scientific data and the results of these randomised controlled trials.

First of all, hundreds of scientific research publications have shown that hyperventilation DIMINISHES oxygen content in body tissues.

Do asthmatics breathe much more air than the medical norm? A typical respiratory minute ventilation for an average asthmatic is about 12-15 L of air in one minute at rest (5 publications are available on my website), while the medical norm is only 6 L/min. Therefore, asthmatics breathe at rest about 2-2.5 times more air than the physiological standard.

Did asthmatics improve their breath parameters during these randomised controlled trials of the Buteyko breathing method? During the most impressive study (Bowler et al, 1998), in 3 months, use of relievers was reduced by 96 percent (25 times less ventolin) and preventers or inhaled steroids by 50%. Respiratory minute volume decreased from their initial 14 L/min to 9.6 L/min, but the physiological norm is only 6 L/min, while Dr. Buteykos hard standard is 4 L/min at rest for a 70-kg man. Hence, during their best shot, the participated asthmatics got only about a half way towards the standard. Consequently, there were a very few asthmatics, if any, who normalized their breath during these trials. They continued to hyperventilate.

The assumption of the medical doctors, who conducted these randomised controlled trials, was that a Buteyko teacher taught the Buteyko breathing method and a controlled group “learned” the method. This is easy to see from the titles, which usually say about a “trial of the Buteyko method”. How could they study the method, if no one learned it?

From a practical view, since I taught the Buteyko method to hundreds of people, the key difficulty during these randomised controlled trials were the following. The participants were mainly limited to practicing breathing exercises (e.g., 40-70 min per day). They could not use the versatile arsenal of life-style addressing tools of the Buteyko method. Breathing normalization process requires 24/7 control of breathing including:
– nasal breathing all the time (hence, it is necessary then to seal ones mouth with a surgical tape, if the mouth is usually dry in the morning; and someone will never solve their problems with asthma, if mouth breathing occurs during each night
– physical exercise (no less than 2 hours daily with only nasal breathing, in and out, otherwise exercise is more or less ineffective for most, especially sick people)
– prevention of sleeping on ones back (we breathe about two times more air, when we sleep on our backs at night)
– and various other lifestyle-related factors so that ones basal breathing pattern is restored back to our physiological standard.

Even more successful results have been discovered after application of the Frolov Breathing Device during recent clinical trails in Russia (under review and to be published in 2011).

Dental implants the most appreciated solution to the missing teeth problem

Though the world of dentistry came out with a number of solutions like bridges and dentures for the missing teeth problem in the beginning of the 19th century, people were unsatisfied with the results that they got from them. The removable dentures were more inconvenient because of the reason that they need to be removed in the night for cleaning. People used to face problems like eating and talking comfortably too.

The world of dentistry and the experienced dentists of it were also aware of the fact and were in search of a process, which would help the missing teeth patients in getting replaceable teeth that would be more natural and functional like the original teeth. Finally, the day came in the early 1960s, when a group of dentists came out with a solution to the missing teeth dilemma naming it, Teeth Implantation. It was a more appreciated solution than the earlier ones as it does not required too much time and was more advanced. It was explained that in dental implants, a prosthetic or artificial tooth will be fitted into the jawbone, where its performance will be almost equal to the natural teeth. The most valuable part of it was that it also provided a natural appearance, where people could smile confidently without hiding their teeth.

Today, the dental implant procedure is no more a new discovery. Every year, hundreds of implants are successfully done in institutions like Implant Solutions in Chicago. The experienced implant surgeons here suggest this procedure to be the most secured and best solution to the missing teeth problem. The total procedure of dental implants is carried out in two phases, ; the surgical phase and the restorative phase.

At Implant Solutions, whenever a patient comes with a missing teeth problem, the doctors take a 3D picture of their jaw and then decide on what type of dental implant should be placed on that particular patient. It is however, not one single doctor who carries out the entire procedure. Usually, the surgical phase is performed by an oral surgeon while a prosthodontist carries out the restorative phase. It is the total team of doctors that makes sure you get the best possible replacement for your missing teeth.

Though the dental implant procedure has a fantastic past record which states that more than 90% of the cases have been successfully completed, it is very important for every patient to select the right team doctors for his dental implants. Implant Solutions is however one of the best in the business and provides some of the most experienced doctors in Chicago. While looking for an implant surgeon, one should always consider the qualification and experience of each of the doctors in the team. Its even better to get more information about the doctors by asking them questions like: –

How many dental implants have you placed?
Where have you done your training for surgical or restorative procedures?
Will you let us see the book references or testimonials from the earlier patients?
How long has it been since you are working in this dental practice?

As soon as you get your answers, you will be able to make a decision as to which route to choose. If the answers satisfy you, you can enquire more about the total cost and the total time-length of the procedure. Its better if you do not keep any questions in your mind.

Once you have decided to undergo a dental implant and have chosen your team of doctors, you can be care free about your operation. The oral surgeons will make sure they explain to you all about the total procedure including your diet chart during your restorative stage. They will also tell you, after looking at your condition whether you can attend work or not. The doctors will take care that they give you all the necessary information you need to know.
