The determination between work and rest is, as engineers are fond of saying,
an 'implementation issue', but it would not be difficult. In it's simplest
form we have the software tell the user to take the first reading at rest,
and the next reading doing an exercise.
The procedure would be done immediately after the dive, and at predetermined
intervals to sniff out latent bubbling.
No direct correlation between bubbles and DCS will be made. The goals of this
sport diving 'tool' would be two-fold:
(1) To alert them to the possible need for recompression treatment, or at
least some IWR, O2, etc.
(2) To provide a general gauge on the efficiency of decompression procedures,
In other words, if you're consistently getting a little bubbling after
a dive, you could select a more conservative deco model, or pad stops,
or use more O2, and then see if this reduces the bubbles.
