hi Mark,
I really appreciate your comments. A lot of good things

In the situation of C02 the diver will be so narked that a competent diver may be able to see signs that all is not well, before the hit takes full effect.
A CO2 hit could happen at shallow depth as well (so no sign of narcosis). I had a bad CO2 in a shallow cave during a very long dive. I hardly think that anybody could have noticed anything before I actualy switched to OC and fixed the problem by myself.

02 convulsions are a massive problem for any diver 0c or CCR unless the diver is using a full face mask or a gaged regulator. From what i understand of 02 hits a solo diver still wouldn't survive this despite the gag or ffm.
If the airway is well protected, why not? the convulsing diver has obviously to be brought back to the surface at one point, but this could wait for a while...

Big improvements in pp02 monitoring equipment (starting with the cells). Cheaply available (preferably on unit) cell testing equipment that can take a cell through air and up to 2.0pp02 on dry land. A c02 analisor on the CCR would help a lot as well.
Very true! We're all waiting for that.

I will run the dive well inside CNS limits possably dropping the set point on deeper dives. Dropping the set point also gives more time to react to solenoid issues should they occur.
Very good point (to be included in the next version of the article!)

I run solo bailout on all dives now so that doesn't make any difference however it is more likely i would bailout to OC on a solo dive than on a buddy dive. On a buddy dive id alert my buddy to a problem and probably try and fly the unit out.
Why flying manually when you are with a buddy and not when you are on you own?
Thanks for sharing your experience
Cheers
