“…7 Questions are scored on a scale of 0-6 with lower numbers representing better control of symptoms. The presence or absence of other co-morbidities commonly found in asthma were assessed by validated questionnaires: the Nijmegen questionnaire was used to quantify levels of hyperventilation with a value of >23 suggestive of hyperventilation 8 and a gastro-oesophageal reflux score was used to assess levels of reflux experienced by the patients, again with higher scores indicating higher levels of reflux. 9 …”

Simply breathing via a mouthpiece and pneumotachograph made end-tidal CO 2 fractional concentration (FET,CO 2 ) decrease progressively both in hyperventilators and in patients with anxiety disorders, but not in normals. At the start of the measurement the FET,CO 2 was not different between patients and healthy subjects. In patients ≤28 yrs, the decrease of FET,CO 2 resulted from a higher tidal volume, and in patients ≥29 years from an increase in frequency. After voluntary hyperventilation, the recovery of FET,CO 2 was delayed in patients, due to a slower normalization of respiratory frequency in females and in older males, and of tidal volume in younger males, and also due to less frequent end-expiratory pauses. When breathing was recorded first by means of inductive plethysmography (Respitrace), the progressive decline of FET,CO 2 seen in patients was not observed: from the onset of the recording, FET,CO 2 was reduced in patients. It did not change further when, immediately afterwards, the subject switched to mouthpiece breathing.The finding that breathing through a mouthpiece induces hyperventilation in patients and that recovery of FET,CO 2 is delayed after voluntary hyperventilation, suggests that the respiratory control system is less resistant to challenges (mouthpiece or voluntary hyperventilation) in those patients. On the other hand, the lower values of FET,CO 2 measured during recording by means of a Respitrace probably result from a challenge, prior to the recordings, induced by the fitting of the measuring device to the patient. This unsteadiness of breathing characterizes patients with hyperventilation syndrome and those with anxiety disorders, but is not sufficiently sensitive to be used for individual diagnosis.

“…Each patient had a clinical diagnosis of DB following a positive Nijmegen score [4,23] (score >23). Patients with metastatic disease, osteoporotic disease, respiratory infection or DB as a consequence of asthma or cardiac disease were excluded from the study.…”
