Abstract

Dysfunctional breathing, defined as an alteration in the normal pattern of breathing [1, 2], is recognised to be an important differential diagnosis for individuals with “unexplained” dyspnoea. It is estimated that dysfunctional breathing is present in up to 10% of the general population [3] and is a prevalent comorbid finding in individuals with airways disease, acting to amplify symptom burden and to confound accurate assessment of disease control [1, 3, 4].
