 Imported post
All,
I was approached by one of my club's dive leaders last night with a question about saw tooth dive profiles. He was trying to explain to a trainee dive leader why a dive in Capernwray which went to 18m, then to 6, then to 18 again and then up to 10 (and could have gone back to 14 if the DL had not have stopped him), was a bad idea.
The reply to the inevitable chat afterwards was "O.K, that's fine, but why"? The DL concerned was therefore asking me.
I tried to explain it in terms of constantly changing pressure gradients and tissue supersaturation. I had to conceive in the end that I was unsure and would find out.
I know there are some pretty clued up people who post in this section. Is there any medical evidence that saw tooth dive profiles are provocative? What is the physiology behind this?
I would be very interested to know, as would one of our DLs and he will gladly pass it on to the trainee concerned!
