Whilst I agree with most of your flow chart there are a few points to consider. Having first hand experience of two o2 convulsion rescues (both sucsessfull)I feel I have some insight as to what goes on.

The diver is very likely to convulse more than once.
there needs to be some awareness of the "off-effect"
removing the diver from high o2 may not stop the convulsions, it may trigger more
It is highly likely that the diver will stop breathing
it is POSSIBLE that the heart may stop of stutter
the diver will become uncounsious for at least 30-50mins (in my experience)
some haulcinations may take place whilst in a semi concoius state
the risk of embolism is VERY high especially if the diver convulses a second (or third time whilst ascending
the second phase of the convulsoin is very difficult to spot.

hope this helps. my opinion is you should get the victim to the surface ASAP you can unbend a diver but you cant undead one!!
