How does the hyperbaric chamber work?

A hyperbaric chamber is a device that, through special conditions created inside the chamber, allows the person inside to breathe pure, concentrated oxygen while increasing the pressure in the body. The use of such a device makes it easier for oxygen to reach hard-to-reach areas of the body. Increasing oxygen levels in the body has many benefits.

Note that the treatment should be performed at least several times for the effects to be visible.
