How effective are breathing exercises for dysfunctional breathing/hyperventilation syndrome (DB/HVS) in adults?
Quality of life was not an outcome measure in this single trial involving 45 patients, and no numerical data or statistical analysis was presented. No information could be extracted from the paper regarding the size of the treatment effects.
DB/HVS is a breathing problem that involves breathing too deeply and/or too rapidly. There are many possible causes of DB/HVS and if left untreated it can lead to a variety of unpleasant symptoms, such as breathlessness, dizziness, tremor, paraesthesia and chest pain. DB/HVS has an estimated prevalence of 9.5% in the general adult population. There is little consensus regarding the most effective management of this patient group
