What you are watching is obviously a drill. The 1,2,3,4 is merely me demonstrating to the students the steps I expect when they are demonstrating the drill to me. It has nothing to do with rescuing the diver.  

 

The reality of the situation is that you will need to make decisions based on the situation you are in. In other words, if the diver is toxing or ceasing, you are better off not ascending but rather waiting a few minutes for the hard convulsions to stop prior to ascending. This will reduce the risk of Lung Over Expansion injuries. In the true case of a Toxing Diver Rescue, the risk is not O2 anymore, but the drowning or near drowning that may occur if the diver inhales water once the convulsions stop. So the regulator is actually just a plug to prevent the diver form inhaling water, hence the reason we purge, therefore we don't really care what gas is in the regulator. Truth is the diver will take a long time to recover from the tox, which hopefully you will no longer be underwater.

Thanks for the reply AG

Its a lot clearer now and I understand why you would wait until to convulsion has finish you would not want to try and ascend with a violently moving casualty.
