Given that we understand so little about the relationship between
decompression and bends symptoms, I'd say that any response to this
situation (unanticipated truncation of planned deco profile) is necessarily
"seat of the pants".  My particular "seat of the pants" approach would be be
get back underwater ASAP, return to depth at which ceiling was violated plus
20 feet or so, then I would do something on the order of 120%-150% of the
time at each stop depth that I had omitted.  If return to the water is
delayed for any length of time (5-ish minutes or more), I would lie
horizontally and relax while others did whatever is necessary to allow me to
return underwater.  If possible, I would be guzzling fresh water during this
period and, if available, would be breathing O2. Of course, if O2 was
available, I'd probably opt to get back U/W with it.  Even if I felt the
need to return to a depth greater than about 20-25 feet, I would be
breathing the O2 at 20-25 feet while waiting for the support folks got me a
mix that I would breathe deeper.  All of this, of course, is contingent upon
specifics...

Aloha,
Rich
