Graphic relative to intraocular blood pressure.
Graphic relative to mean perfusion pressure.
Another goal of our project was to give us an idea of the way to
acquire and to properly work with biological signs.
Opportunity to appreciate one of the many possible areas of interest of our
degree and ended up having a clarifying experience about that.
Idea of the mechanisms behind the working way of several of our
main systems and a good introduction to the eye and nervous system’s
physiology.
This is specially important since we realized it is sometimes hard to
analyze data due to the lack of signal, problems with the software
and/or hardware or even a slight movement of the patient, which can
all generate inconclusive data in our case, for example.
At the end of our work we have
some topics to meditate on, like:
1.Having ended up with some results
that differ from the gathered data of
some other studies.
2.Although these results vary, the
main goal of the research ended up as
expected and as supported by other
recognized studies.
After this, we hope our
project can combine with
others and be helpful for
the institution we have
been working with and,
more important than that,
for us, THE PEOPLE.
