 St. Matt's DEEP Page


As you know, we conducted an experiment in which we found out how the
pressure at different depths differs. We used Henry's Law to back up
our experiment. Henry's Law states that the gasses in our lungs, mostly
Nitrogen, can be dissolved into a liquid. This amount of gas molecules
is proportional to the pressure of the gasses. When the gas is under
high pressure, more of the gas will be dissolved into a liquid. When
this happens, the gasses from a divers lungs gets forced into the
bloodstream. As the diver goes deeper into the water, there is more
pressure being put on the lungs causing more Nitrogen to be forced into
the bloodstream. If the diver surfaces too quickly, bubbles will form
in the bloodstream. These bubbles can block capillaries and cause blood
to stop flowing. Blood can also be stopped flowing to the brain and
heart causing death. The bubbles of Nitrogen in the bloodstream cause a
lot of pain, this immense amount of pain makes the diver bend over.
This is why this condition is called "The Bends."
The only way to cure "The Bends" is to put the diver in a decompression
chamber and neutralize the pressure on their body. The diver just went
from a very high pressure in the water to a very low pressure in the
water by ascending. So the chamber is under very high pressure. Then
doctors lower the pressure in the chamber very slowly so the diver can
get used to a new amount of pressure. It can take up to twelve to
fourteen days to complete this procedure. But when it is all done, the
diver is fine with a normal amount of pressure just like everyone else.
