Explanation
The most important of which is an epileptic-like
convulsion which can cause a diver to drown.
Central nervous system toxicity limit fraction.
See Tissue group
Decompression sickness/illness. Any of a variety of
maladies resulting either directly or indirectly from the
formation of nitrogen or helium bubbles in tissues or
body fluids, as a result of inadequately controlled
decompression.
Time spent at a decompression stop, or range, before
surfacing, to allow absorbed nitrogen to escape
naturally from tissues.
On a decompression dive, the depth range between the
floor and the ceiling within which a diver must stop for
some time during ascent.
A group of repetitive dives between which the dive
computer indicates some nitrogen loading is present.
When nitrogen loading reaches zero the dive computer
deactivates.
Elapsed time between leaving the surface to descend,
and returning to the surface at the end of a dive.
The deepest depth during a decompression dive where
it is recommended to stop for an effective
decompression.
Helium percentage or helium fraction in the breathing
gas.
Maximum operating depth of a breathing gas is the
depth at which the partial pressure of oxygen (pO
the gas mix exceeds a safe limit.
A single or repetitive dive that includes time spent at
various depths and therefore has no decompression
limits that are not determined solely by the maximum
depth reached.
In sports diving, refers to any mix with a higher fraction
of oxygen than standard air.
No decompression stop time. The maximum amount of
time a diver may remain at a particular depth without
