I read an article (cant find it now) that said people have been able to hold their breath for up to 15 minutes using a special technique. I believe the technique went like this : 20 deep breaths breathing normal air, then 20 breaths using 100% O2.
I cant find the article, so heres my questions. Does anyone know why this technique would increase breath-hold time? Is it possible for blood to become super saturated with oxygen?
I know its recommended that free-divers do not breath nitrox or pure O2 before diving. Why?
