Rescue of an O2 toxicity victim

I've read all post I can find on the subject but couldn't find a definitive recommendation.

Can anyone give an answer and state the underlying reasons for each step of the procedure?

thanks

Thanks for the link...

Would it be better to bring convulsing victim up immediately? Of course taking into account the rescuer's safety. To limit aspiration of water.

or

Would it be more prudent to wait till the convulsions have stopped to lower the chance of AGE? Will the glottis be definitely closed in seizure episodes?

Any more information will be appreciated.

Successful rescues have been accomplished using both methods.
FEW successful rescues have been accomplished using either method.
Costeau performed a self-rescue using a direct ascent, but I would assume that if he was self-aware enough to ascend that he would also have been self-aware enough to not have a locked glottis.

No, the glottis is not guaranteed to be locked during convulsion, but how are you going to know?

Tox is nasty. To be blunt, unless the toxing diver is using a FFM, I would expect a fatality and be extremely happy with anything better.

Successful rescues have been accomplished using both methods..

This report of GUE training class describes a successful rescue of a diver that tox'd while breathing a tank with 50% O2 rather than the expected 30/30 at a depth of 36m (ppO2 of 2.3).

About 19 minutes into the dive, the student convulsed at depth for 2 minutes, and then again for a minute at 17 meters.
