Buteyko Clinic International (BCI) is a global breathing education organisation that trains individuals and healthcare professionals in the Buteyko Method — a clinically studied approach to functional breathing developed by Russian doctor Konstantin Buteyko. The clinic is led by Patrick McKeown, who trained directly under Professor Buteyko and is the author of ten books on breathing, including The Oxygen Advantage.
BCI offers a library of self-paced online courses aimed at everyday issues such as anxiety and stress, sleep and snoring, asthma and respiratory health, and menopause, alongside a longer online instructor certification for those who want to teach the method professionally. All programs are built around the same core Buteyko principles: nasal breathing, slowing the breath, and improving tolerance to carbon dioxide.
The organisation positions itself as the largest Buteyko training body worldwide, with a network of certified instructors and a focus on science-backed, practical techniques for daily use.
