Brief Summary

The aim of the research project was to investigate the effects of hyperbaric oxygen (HBO) treatment on the redox equilibrium in individuals with different pathological conditions. Both hyperbaric oxygenation and the pathological condition are associated with redox imbalance (oxidative stress), however, HBO is successfully used in the treatment of chronic wounds, e.g., diabetic foot syndrome, as well as in sudden and acute hearing loss, e.g., acute acoustic trauma or idiopathic sudden sensorineural hearing loss.

Study Arms (2)

Patients

EXPERIMENTAL

Hyperbaric oxygen (HBO) therapy.

Procedure: Hyperbaric Oxygen Therapy

Controls

NO INTERVENTION

Healthy individuals that never treated with HBO therapy.

Interventions

HBO session includes three 20-minute inhalations of pure oxygen in a hyperbaric chamber utilizing specially fitted face masks for each patient. The session is conducted as follows: 10 minutes compression of up to 2.5 atm (0.25 MPa), inhalation of 100% oxygen for 20 minutes, a 5-minute break in the chamber without the mask (oxygen concentration up to 23%, constant temperature (room) and humidity), again 20 minutes inhalation of 100% oxygen, another 5-minute break (the same condition), the last 20 minutes inhalation of 100% oxygen, and finally a 10-minute decompression. The total duration of the session was 90 minutes.
