Effects of an Early Detection System for Barotrauma During Hyperbaric Oxygen Therapy

Introduction: Although hyperbaric oxygen therapy is required in disasters or emergency situations, barotrauma, which the most common complication, continues to occur. If barotrauma occurs during treatment, treatment stopped, and there no proper preventive method for this. Therefore, authors evaluated degree of prevention by applying a tympanometry-based anti-barotrauma device (ABT). Method: The candidates clinical trial are adults between ages 18 65 who correspond academic indications therapy. In prospective parallel design, were placed test group control group. Simple randomization one-sided blinding applied. medical staff directly observed severity middle ear through video otoscope. number interruptions completions along with findings from otoscope observation (Grade 0~5) such as level pain (pain scale value) collected at three university hospitals. Results: When ABT was applied, it possible prevent earlier than traditional observation. However, since application requires patient's voluntary cooperation, difficult if patient has reduced consciousness unable follow instructions staff. Conclusion: Applying an appropriate early detection barotrauma. order be applicable patients difficulty automatic intrinsic pressure reduction system should developed.
