What is the Nijmegen Questionnaire?
The Nijmegen Questionnaire was introduced over 30 years ago as a screening tool to detect patients with hyperventilation complaints that could benefit from breathing regulation through capnographic feedback [1].
Is the Nijmegen Questionnaire still relevant in the diagnosis of hyperventilation syndrome?
The diagnosis of hyperventilation syndrome (HVS) was questioned and slowly disappeared. Nevertheless, the Nijmegen Questionnaire has remained in use and we have noticed even a recent increase in studies in clinical medicine as well as requests for permission to use the Nijmegen Questionnaire in new studies.
Does breathing regulation normalise the Nijmegen Questionnaire?
Secondly, when breathing regulation is able to solve the problem that caused the high Nijmegen Questionnaire score, the score does indeed normalise to around 12. In other studies of individual breathing regulation of patients without comorbidity, normalisation of Nijmegen Questionnaire values post-treatment was also found [ 12, 22 ].

What is the Nijmegen breathing test?
The Nijmegen Breathing Test is an easy and reliable method used in breathing clinics and research around the world to help people identify breathing dysfunctions. Why? Because dysfunctions such as Hyperventilation Syndrome (HVS), are more common than you think and 1 in 10 people have HVS.
Does a high Nijmegen Questionnaire score indicate hyperventilation syndrome?
Neither study attempted to differentiate “hyperventilation” complaints from anxiety disorder or other stress-or anxiety-related problems, nor has this been done in later studies. Thus, a high Nijmegen Questionnaire score does not indicate a specific syndrome.
