ReOxy Therapy in the Rehabilitation of Chronic Low Back Pain Patients With Comorbidity

"ReOxy therapy is a protocol which employs passive (the patient is at rest), short (up to 10 min) mild normobaric hypoxic exposures alternated with similar duration intervals of breathing hyperoxia (up to 5 min). The gas mixtures are supplied to a patient via facial mask on continued measuring of oxygenation status of the patients, lasting about 45 min in total per treatment session.~The hypoxic load will be individually adjusted, based on the results of a preliminary hypoxic test. The patient inhales air with low oxygen content (10-14%) at atmospheric pressure in a continuous mode through a mask withing 10-min.~During the ReOxy - treatment session, the software automatically adjusts the gas mixture switching, based on changes in physiological parameters (blood oxygen saturation and heart rate) in response to hypoxic and hyperoxic impact (biofeedback control)."

Placebo treatment with 'sham' ambient air breathing to simulate ReOxy-therapy sessions. Placebo-mode breathing set visually similar to standard breathing set but have a mask with open intake valve. The masks are chosen in a way to provide maximum degree of similarity to reduce the risk of unblinding on the patient-side.
