Recently, I had a long talk with an Italian instructor (ciao,
Giancarlo, come estai?), who is qualified to use an oxygen
fully-closed circuit rebreather (when he became an instructor, the
FIAS required competence in using a rebreather - the requirement has
since been dropped).
Naturally, one obvious use for such a thing would be to degas with
pure oxygen on surface intervals, and why not, during the last stop.
He strongly warned me against it, for you would be degassing
nitrogen (and/or whatever) into the counterlung bag, and you'd have
to manually purge the system every so often, to the point of making
the practice dangerous, for soon you'd be breathing no O2...
Note that this would presumably would not be an issue with a
semi-closed rebreather, but I won't go further into it, the closer
I've been to a rebreather was an old biomarine unit in a museum
display case...
- -------- Vive le Quebec Libre! (C. De Gaulle, Montreal, 1967) -------- -
.... is english Canada's continued debasement of quebecers reputations and
the all-too willing nature of the English media to portray [Qu=E9bec] as=
a
crumbling banana republic. It amounts to one of the grossest and longest-
standing libels of a people in this country's history - and there are no
journalists in english Canada trying to do anything about it.
