I still keep seeing this word IF apearing. Nowhere has it been shown that victims wouldnt start breathing again.

I think this is very important that we once and for all dispell this myth one way or another. (Especially for those that wear FFM)

IS THERE ANY EVIDENCE THAT A FFM WEARING DIVER WOULD NOT START BREATHING AGAIN UNAIDED? Everything I have read suggests they would.

If I convulse whilst wearing a FFM Id hate to die of AGE or masses of missed deco because someone dragged me to the surface when there was no need to. Sure I may be combative or confused for quiet some time but isnt it worth trying?

I am obviously not talking about blowing a meer 30mins of deco here.

With a FFM diver wouldnt it be best to;

a) wait for the convulsion to stop,
b) ascend slowly and await for the divers breathing response to kick in,
c) try to do as much deco as possible

If this is too difficult due to a combative diver or other factors fine - but surely its worth a try rather than having a blanket - ascend imediately forget deco policy. If we have a buddy take a CO2 hit during a dive we dont just bolt for the surface even if they are uncooperative/unresponsive some effort is made to do deco if possible.

Its very easy for the USN to say bring a toxing FFM diver straight to the surface when they have a staffed chamber on the boat where they can be recompressed!

Exactly. That's how I hope anyone with an intact loop, FFM/gag or otherwise, would be treated.

I phoned our local chamber and they had never heard of breathing not re-starting. I have never heard of any cases at all where breathing hadn't restarted except the two that Dave T mentioned, and who's to say whether or not that was as a result of inhaled water rather than the tox itself?

I have got a mantabite/gag combo. I am assuming that if I tox, I will at some stage recover. If I can't self-rescue, I am hoping that some kind soul will come and find me (I have 3 hours guaranteed by AP for you to do this, so please do try...

) and bring me up, breathing, and doing my deco for me. I am assuming that my PO2 will have remained very high, so although I may multi-tox, my actual deco will be less than my VR£ says.

Please don't screw up all my hard work by launching me like a Polaris at the boat! Adding concussion and DCS to my problems won't help...
