    There seem to be two schools of thought in freediving medicine circles that a samba is either caused by oxygen lack or CO2 build-up. As a rebreather diver, and hence properly neurotic about CO2, I tend to favour the latter but I'm a physicist not a biologist. The test for me has always been the fact that I have run my blood hemoglobin down to blue and not blacked out but never seen blue lips on a sambaing freediver. I just can't see how they are low on oxygen at that point. The fact that all you have to do is grab them and they come round also perplexes me. It should be getting worse with the delay which ever it is but it gets better.

    Your point on CO2 tolerance. Yes it is a key trick freediving but it is the thing that will kill us as in the limit we samba and need support.

    Where do you want to come with these two post? I have two black out's and both happend when I was pushing myself a bit to far and I DONT BLACK FOR FUN.

    Freediving is fun and there is alot of security behind it. We have support divers that knows exactly what to do in case of an emergency.

    Edvin, your posts make it seem like you black out often just to do it and that is where I see the humor. I will go away now, seeing you are trying to have an adult conversation.

    Old thread, new addition

    I know this is an old thread but we have just received permission from the South Pacific Underwater Medicine Society (SPUMS) to include their journal in our Repository. The addition of their collection is huge since it covers well over 30 years of scientific work. The early issues are more of a newsletter format and it later progressed to the amazing medical journal that exists today. Anyway... I added this paper last night and thought it added an interesting point of view for this thread (though not exactly what is being discussed, just interesting...).
