It appears that the consensus opinion is: gas them!

Providing 100% normobaric O2 will has many beneficial effects:
1.  Increased offgas rate
2.  Bubble size reduction
3.  Increase O2'nation of any areas w/ compromised circulation
4.  Possibly reduce edema.

Thus it should not be withheld from a suspected DCI victim.  Should px 
convulse, discontinue O2 till seizures subside (like a grand mal 
seizure it is self-limiting & should B handled like a grand mal 
seizure).

Once seizure has subsided, O2 may be resumed.

Victim will not be denied chamber treatment, although the history of 
gases the victim was exposed 2 will be considered when determining 
protocol.
