The human body accumulates inert gasses when exposed to higher pressures than
environmental pressure, which in a decrement of the pressure, or decompression, will
expand and form bubbles inside several body tissues. The concentration of inert gasses
depends on pressure and time exposed to the pressure. The more inert gas accumulated
the more time the person has to expend at ascension to get rid of the access.
Professional divers spend lots of time disposing gasses out of their body on their way
up, as they spend lots of time at great depths. What makes the job of the team longer to
accomplish and more expensive to do.
By controlling the proportions of the gas breathed by the diver, we can reduce the
concentration of gasses in blood. Resulting in a safer and faster ascension. The solution
proposed in this document, is a dynamic control of the proportions of a breathing mix
(Oxygen/Nitrogen) used in the actuality. By tuning the proportions of the mix according
to the divers needs, the accumulation of inert gasses is reduced, which leads to an
improvement of the waiting time the divers have to wait before exiting the water, in
addition to their safety.
Instead of sticking to a fix proportion, as it’s done in the traditional diving, the mix will
adapt every moment to the depth of the diver. The automatization of the breathing gas
supply will reduce the human fault accident common at the sector. And will help at the
task of monetarizing the decompression of the diver at ascension. The expected result
is a much faster and safer ascension, what will trim down the time professional works
takes to accomplish, making the diving team more competitive and cheap. |
