The Capnotrainer is a non-invasive biofeedback assessment tool that provides information about breathing physiology by showing the partial pressure of carbon dioxide in exhaled air. Changes in breathing patterns are a learned behavior that can be triggered by a stressful situation or cause a wide variety of symptoms, including chronic pain, muscle tension and headaches. Normal breathing mechanics play a key role in posture and spinal stabilization. The capnotrainer can help patients to understand and experience the correct rate of breathing as well as experience the sensations associated
with restoring normal carbon dioxide levels.
