The Hyberbaric Chamber is a physiotherapy instrument consisting of a steel drum which serves to shut people and to produce a higher atmospheric pressure that what we usually have and provide pure oxygen to breathe. It's basis is that our body needs a certain amount of this gas to keep working. In some diseases and accidents, we don't irrigated oxygen throughout the body. The purpose of the camera is to add more pressure on the blood plasma so the fluid is dissolved and can reach places it normally don't reach.
Its mechanism is derived from the physical laws of gas diffusion in the tissues under increased atmospheric pressure, which are Boyle's law and Henry's Law, and pharmacological principles of oxygen. Hyperbaric chambers (hyper = more, baro = pressure) may be called the most developed stage of the first diving suits, which operated under the same physical principles to avoid decompression sickness when divers down to great depths.
