“…The Nijmegen questionnaire has recently been validated in asthmatics with a single study. The approximate prevalence of HVS in asthmatics was found to be 34% [13]. As many of the symptoms described in the Nijmegen questionnaire will occur in asthma the true prevalence of HVS in asthmatics is likely to be overestimated.…”

Dysfunctional breathing: a review of the literature and proposal for classification

et al. 2016

Dysfunctional breathing is a term describing breathing disorders where chronic changes in breathing pattern result in dyspnoea and other symptoms in the absence or in excess of the magnitude of physiological respiratory or cardiac disease. We reviewed the literature and propose a classification system for the common dysfunctional breathing patterns described. The literature was searched using the terms: dysfunctional breathing, hyperventilation, Nijmegen questionnaire and thoraco-abdominal asynchrony. We have summarised the presentation, assessment and treatment of dysfunctional breathing, and propose that the following system be used for classification. 1) Hyperventilation syndrome: associated with symptoms both related to respiratory alkalosis and independent of hypocapnia. 2) Periodic deep sighing: frequent sighing with an irregular breathing pattern. 3) Thoracic dominant breathing: can often manifest in somatic disease, if occurring without disease it may be considered dysfunctional and results in dyspnoea. 4) Forced abdominal expiration: these patients utilise inappropriate and excessive abdominal muscle contraction to aid expiration. 5) Thoraco-abdominal asynchrony: where there is delay between rib cage and abdominal contraction resulting in ineffective breathing mechanics.This review highlights the common abnormalities, current diagnostic methods and therapeutic implications in dysfunctional breathing. Future work should aim to further investigate the prevalence, clinical associations and treatment of these presentations. @ERSpublications A review of common abnormalities, current diagnostic methods and therapeutic implications in dysfunctional breathing http://ow.ly/ZTzK6

“…They overlap with symptoms of panic disorder but only a subgroup of patients with high scores on the Nijmegen Questionnaire have been actually diagnosed as having panic disorder [7]. Many asthmatics have an elevated Nijmegen Questionnaire score [9, 10], which corresponds with poor asthma control [9, 11]. Breathing pattern disorder is also related to the Nijmegen Questionnaire score [12].…”

“…Breathing pattern disorder is also related to the Nijmegen Questionnaire score [12]. The relationship with hypocapnia is variable and often too weak to call the Nijmegen Questionnaire score a measure of hyperventilation [9, 13]. Thus, we prefer to describe the Nijmegen Questionnaire score a measure of “functional respiratory complaints”.…”

“…Multicomponent assessment is required. In the clinical evaluation of the presence of dysfunctional breathing, therefore, objective criteria, derived from the somatic functions of breathing, play an important role [9, 20]. It seems desirable, therefore, to use at least two kinds of criteria, subjective and objective, to assess dysfunctional breathing.…”

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]. It was validated against the Hyperventilation Provocation Test [2], on the assumption at the time that hypocapnia was causally related to complaints. In later studies, the correlation between Nijmegen Questionnaire scores and carbon dioxide tensions appeared highly variable. 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. We would like to formally declare here that the Nijmegen Questionnaire is not copyrighted and is free to use. It has been or will be translated, as far as we know, into Greek, Farsi, Finnish, Norwegian, Swedish, Spanish, Filipino and Chinese. However, the validity of the Nijmegen Questionnaire is often a point of discussion and we would like to make a few comments on that issue [3].

“…Many patients who have a confirmed diagnosis of asthma can score highly on the Nijmegen questionnaire [2, 14], which may relate to poor asthma control. While this reduces the utility of the questionnaire, it is still a very useful way of finding out about the frequency of symptoms the patient experiences, but this must only be part of the investigation process rather than the whole content.…”

Dyspnoea, hyperventilation and functional cough: a guide to which tests help sort them out

Dyspnoea is a multifactorial symptom, defined by the American Thoracic Society as “a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity” [1]. Dyspnoea is caused by a wide range of conditions, ranging from asthma to pulmonary embolism, and including such nonrespiratory factors such as diabetic ketoacidosis. A patient with asthma who is aware of an increase in the muscular work of breathing during an attack, another patient with a pneumothorax experiencing increased efferent nerve stimulation from pulmonary stretch receptors and a third patient with type 1 respiratory failure would all describe themselves as “breathless”, but for very different physiological reasons. Identifying the exact source of the patient’s symptoms can be a lengthy process.
