Warning: This is an approximation based on the
dive profile, which itself is an approximation only. Do not bet your
life on this kind of information: There is absolutely
no way to for either programs or dive computers to know the exact
nitrogen load of any tissue. In addition your body may not be
able to remove the nitrogen with the same speed every day.
On the other hand the values used in these approximations seem to be
fairly conservative.
Showing tissue load in percent of the acceptable surface load:
(Postscript)
This picture was generated by mosquitograph --load-surface-% file_name.dive
0% margin is the nitrogen saturation when breathing normal air at the
surface. 100% is the critical borderline for the nitrogen saturation
at the surface level. One should try to stay way below that
border, say at 75% or so.
See the warning above.
This is like the graph above, but 100% is the borderline for the current depth at any time.
See the warning above.
Showing decompression ceilings:
(Postscript)
This picture was generated by mosquitograph -C 0.75 file_name.dive
and shows the minimum depth a diver should no cross at any given time.
This ceiling is an approximation, based on approximations, and need
not be correct
(see this warning).
The example above does use a safety margin of 25%, though, and should
be pretty much on the safe side.
Showing load, continued:
(Postscript)
(Postscript)
These picture were generated by mosquitograph -lc file_name[12].dive
and shows a two dives with only a very short surface interval
between them. Therefore the second dive starts with a higher tissue
load.
Note that the program would need the profiles of all dives since the last complete desaturation to do this perfectly.
