Capnometry Assisted Respiratory Training

Traditional breathing retraining encourages slow breathing, which is likely to lead to compensatory deep breathing, exacerbating hyperventilation and intensifying hypocapnic symptoms. Dysfunctional breathing, primarily in the form of hyperventilation, has been reported to play a major role for some people with anxiety and panic disorders. Capnographic feedback uses a capnometer to assist people in becoming aware of the impact dysfunctional breathing has on their symptoms and aid them in learning balanced, healthy breathing patterns.  Capnometry assisted respiratory training differs substantially from traditional breathing retraining, as it assures accurate assessment and correction of respiratory physiology.

In contrast to traditional breathing retraining, capnometry guided respiratory training uses immediate feedback of exhaled CO2 to teach people to raise their levels of CO2, correct dysfunctional respiratory patterns, and gain control over associated panic symptoms (eg, shortness of breath, dizziness). This method has been shown to improve panic symptoms in part through reducing hypocapnic breathing. The aim is physiological stabilization by inducing reflexive, brainstem–driven breathing regardless of the context.
