Treatment Methodology:
The procedure involves the individual sitting within a compact, sealed chamber where the air pressure is elevated to threefold the standard atmospheric pressure for a duration of 60 to 120 minutes. A typical treatment regimen consists of 20 to 40 such sessions.

Considerations and Potential Risks:
The treatment carries certain risks, including the potential for damage to the ears, sinuses, and lungs due to the increased pressure. Other concerns include a temporary exacerbation of myopia, the possibility of claustrophobia, and the risk of oxygen poisoning. Additionally, the cost could be a significant factor, as the treatment is typically accessible only through private healthcare providers.

Research Overview:
The efficacy of this treatment has been the subject of research, including an analysis conducted by the Cochrane Collaboration.

Research Conclusions:
The available research was unable to conclusively determine the impact of this treatment on tinnitus improvement. Specifically, the studies reviewed did not demonstrate significant benefits for individuals experiencing chronic tinnitus, defined as tinnitus persisting for more than six months.
