A blackout at 17 meters
A blackout at 17 meters depth. More info:
http://www.freediving.biz/features/ga...
Freedivers safety was ensured by lanyard, anti ballast system, meeting freedivers and doctor at surface. No lasting injuries was experienced.
From the comments below:
"brain damage", "brain sought oxygen", "involuntarily open mouth", Water in lungs".
Why do people talk about things they seem to know very little about.
Competition freediving use to be a 0% fatality sport. One person died 2013 in Bahamas during a competition.
People black out occasionally under water during competition dives. In none of these cases has water entered lungs or brain damage occurred.
Water enter lungs when freediver laryngospasm lets go fo the body (when epiglottis opens, which does not happen directly at BO).
When a freediver BO´s there can be as much as 50% of oxygen left in the system. The remaining O2 iconcentrated to the brain. Most brain functions are still active during a BO like this. There is no active body control, no seeing, but she hears and feels. BO´s are often accompanied by dreaming. This one was a deep BO´in double sense. It was at 17 meters it took a long time for her to be aware again. She had no injuries from this accident, she moved on to become top 5 in the world some years later.
