Clinical Trials Investigating the Buteyko Method
There are countless clinical trials that have investigated the Buteyko Method as a treatment for a wide range of health concerns including asthma, dysfunctional breathing, sleep apnea and more.
This includes studies in collaboration with Buteyko Clinic CEO and Director of Education, Patrick McKeown. The Buteyko clinical trials showed positive results including improved asthma control, improved lung function and reduced need for asthma medication. Links to each of the studies conducted on the Buteyko Breathing Method for asthma are available below.
1. Breathing Re-Education and Phenotypes of Sleep Apnea: A Review
1. Breathing Re-Education and Phenotypes of Sleep Apnea: A Review
This review examines the four phenotypes of OSAHS and looks at how these can be targeted using breathing re-education from three dimensions of functional breathing – biomechanical, biochemical and resonant frequency. The review concluded that breathing re-education and myofunctional therapy could be helpful for individuals across all four phenotypes of OSAHS.

6. Buteyko Breathing Technique for Exertion-Induced Paradoxical Vocal Fold Motion (EI-PVFM)
The purpose of this study was to determine the effectiveness of the Buteyko Breathing Technique in lessening dyspnea in patients with one form of Paradoxical Vocal Fold Motion (PVFM), exertion-induced PVFM (EI-PVFM), concomitant with hyperventilation. The findings were post-treatment decreases in dyspnea severity, RTMV and HR, in addition to increases in ETCO2. There were also decreases in RTMV and dyspnea which remained after correction for alpha inflation. Therefore, the Buteyko Breathing Method could be useful for individuals with hyperventilation and EI-PVFM. Katz, D et al, 2019. Epub. Volume 35, Issue 1, pp. 40-51.

7. Asthma – A Disease of How We Breathe: Role of Breathing Exercises and Pranayam
To describe the role of breathing exercises in managing childhood asthma, the authors conducted an updated literature search and discovered relevant literature. They discovered breathing exercises are typically multi-component packaged interventions and modify the pattern of breathing to lessen hyperventilation resulting in normalisation of CO2 levels and reduction of bronchospasm, leading to breathlessness. They discovered 10 clinical trials on the topic and found incorporating breathing exercises could improve asthma and quality of life but it must be further researched. Sankar, J, Das, R, 2017.

The objectives of this review were to determine whether breathing exercises in people with dysfunctional breathing/hyperventilation syndrome have beneficial effects as measured by quality of life and to discover if there are any adverse effects of breathing methods for these patients. The results of this review were unable to inform clinical practice as a result of only one small, poorly reported RCT. They did not find any credible evidence regarding the effectiveness of breathing exercises in easing the symptoms for these issues. The authors state that since breathing exercises are used regularly to treat these health concerns, there is a dire need for further research. Jones, M, Harvey, A, Marston, L, O’Connell, N, 2013.

The goal of this randomized controlled trial was to test whether the placebo or nonspecific enhancement of well-being brought about by a health-promoting behaviour was a result of the response expectancy theory or the motivational concordance theory. A total of 57 participants completed a breathing exercise – the Buteyko Method over a 4-day period. The results remained consistent with the hypothesis that placebo effects in therapeutic contexts are mediated through the affective consequences of performing a motivated ritual.

26. Investigating the Claims of Konstantin Buteyko, M.D., Ph.D.: The Relationship of Breath Holding Time to End Tidal CO2 and Other Proposed Measures of Dysfunctional Breathing
This comparative study tests Buteyko’s claims and explores the relationship between end-tidal carbon dioxide (ETCO) and BHT in addition to dysfunctional breathing, including the Nijmegen questionnaire, the Self Evaluation of Breathing Questionnaire, and thoracic dominant breathing pattern. The findings showed while BHT does not predict resting ETCO, it does correlate with breathing patterns in participants with abnormal spirometry. It is proposed that altered breathing pattern could assist in breathing symptoms like dyspnea. In addition, breathing therapies like the Buteyko Breathing Method could influence symptoms by enhancing the efficiency of the biomechanics of breathing. Courtney, R, Cohen, M, 2007.

Jill McGowan was convinced the Buteyko Breathing Method could reduce the medication needs of individuals with asthma. So, she gave up her nursing job and sold her belongings to finance her research. Training was found to require five 90-minute sessions. The 30-minute exercise program must be repeated six times per day at first. This paper concludes that this method could have a significant impact on asthma management and potentially result in huge savings on cost. Millar, B. (2006) Nurs Strand. Volume 20, Issue 31.

The aim of this survey was to estimate how prevalent dysfunctional breathing is in adults with asthma and how it is treated. The survey included a postal questionnaire survey and 7033 patients between 17-65 with diagnosed asthma who were receiving treatment. The survey found around one third of women and one fifth of men with asthma may have dysfunctional breathing. It also suggested further studies are needed to confirm the validity of this screening tool and results and that these prevalences may suggest scope for therapeutic intervention and could explain the success of the Buteyko Breathing Method in treating asthma to date.

35. The Effects of Carbon Dioxide on Exercise-Induced Asthma: An Unlikely Explanation for the Effects of Buteyko Breathing Training
The goal of this Buteyko clinical trial was to examine the effect of breathing 3% carbon dioxide on exercise-induced asthma, as a raised airway CO2 level is claimed to mediate the effects of the Buteyko Breathing Method. The study concluded breathing 3% CO2 during exercise does not prevent exercise-induced asthma. The shape of the FEV1 response curve after 3% CO2 suggests that a greater degree of exercise-induced asthma was opposed by a direct relaxant effect of CO2 on the airway. It also suggests that increased airway CO2 by itself is likely not a mechanism for the reported benefits of BBT, however, further study of the effects of hypoventilation in asthma should be investigated.
