AIDA Freediving World Championship 2022 - Marianna Gillespie CWT 104 black out 

You are right my friend, when I got introduced to him I was surprised because I felt a man of that talent should be well known and appreciated.

I would blame myself if I hear about an opportunity like this and I let it waste, please I am interested how can I do business with him.

😂

Absolutely. I was shown this video in my first free diving lesson. It was educational and eye opening.

Or you don't wake up 🤦‍♂️

What causes it?

@@drknow1997 I had my menstruation that day, my blood pressure got so low. 😅

@@drknow1997 it's when you dive, then get turned around and think your going back up but you just keep diving deeper, then realize how far away you are from the surface. Lol.

@Dr Know Shallow water blackout. She's been using up the O2 in her lungs, but when deep, due to pressure, that O2 partial pressure in the lungs is still a lot higher than in air at sea level. But as she approaches the surface, that supplementary pressure falls to near zero and the O2 partial pressure in the lungs plummets, and it can no longer oxygenate the blood.

She is not Okay! She is a wreck.

Ik but in my opinion she did spend quite a bit of time slowly swimming to get the tag and that’s what caused her to blackout

"She's okay"???! She was dead and they brought her back. She will never be "Okay". Like a fighter in a boxing ring, the referee has a job to save the fighter from continuing. ALL those "Safety divers" failed in their job by not intervening much, much earlier. She should sue every single one of them. The lot are a bunch of sod.

@@donemigholzjr.7344 No, she was not dead! Blackout occurs when oxygen partial pressure reaches one-tenth of an atmosphere. Brain damage does not occur until one-twentieth of an atmosphere partial pressure. Many freedivers have blacked out, and as long as they are brought to the surface and they resume breathing within a few minutes, there's no damage done. It's actually rather common among competitive freedivers, and occasionally among spear-fishers. A knockout in boxing is very different. That's caused by physical damage to the brain. I guarantee you she will not be suing the safety divers. She'll be thanking them. They did their job exactly as they were supposed to. Note that in the video, the safety diver grabs her the moment she drops her arms, and within 2 or 3 seconds of the first indication of trouble. And that she's fine afterwards. I was in a freediving class where two of the students came into the class saying "Fifty meters or blackout!" They were determined to get to 50 meters or black out trying. Both made it, BTW. As long as the safety divers know what they're doing, as they did in this video, a blackout will not result in permanent damage. Though I would not recommend doing it on purpose! Where people die is when they don't have trained safety people.

@@johnhornsby1771 Freedivers swim slowly to conserve oxygen. Below a certain point you become negatively buoyant due to the compression of the air in your lungs. At this point a freediver stops kicking and just lets themself sink. This gets them down with the least consumption of oxygen. You'll see this in every video of deep freediving. Blackout occurs most often in the last 15 feet coming back up, because as the pressure drops and the air in the lungs expands, the partial pressure of oxygen drops along with it. This is called "shallow water blackout." Sooner or later it happens to many, if not most, high-level competitive freedivers and some spear-fishers.

Thats what they are trained for. He was going his job.

Yes. Maybe his job. The point is he did extremely well.

Great beach

Tom Cruise can hold his breath for over 6 hours.

Right?! I didn’t even know this sport existed. Wow.

Seems like a hassle, usually you would hold on to a weight to h9 deep in free diving. This seems excessively dangerous as was demonstrated here.

Да. Это вам не на Эверест лазить 😁

@@ALLinHerMovementsme either! I watched “The Deepest Breath” on Netflix so now I’ve been trying to find out more about it!

She didn't drown she blacked out. Just need to get her to the surface and her head out of the water asap until she regains consciousness.

I would not do this…

That first safety diver had mechanical propeller help to get there and back. But they are still impressive.

They are also elite free divers.

Im a diver and this video made me shit myself. Also, the mask the man on the boat was holding up to her face is a BVM with a one way valve, he was not squeezing the bag to provide blow by oxygen and was therefore actually suffocating her while she was profoundly hypoxic status post loss of consciousness. This comment is actually a PSA for all healthcare providers if providing blowby O2 with a BVM.

Audrey mestre was a complete different accident. She was 150 meters + below the water

You can see unprofessionalism of safety team in 2018 cmas wc, Ramon Carreno.

Здравствуйте. Служба Спасения сначала аквалангист. Ей оказана грамотная скорая помощь именно верного характера. Где вы видите нападение ?

☝️

нет т. к. словила блекаут

No, she didn't win gold. You get disqualified if you black out, or if you come close enough to black out that you can't competently complete the survace protocols (remove goggles, make ok sign, say 'I'm ok' to the judges, keep head above water until the time limit has passed).

انا من مغرب شعب بيرو طيب كانت زارتنا عائلة من بيرو في مغرب و عزمناهم عندنا في بيت عائلة من اب و ام و بنتين ولكن للئسف لم نبقى نتاوصل

맞아요 프리다이버 기욤 네리도 천사라고 했는데 공감합니다

I was wondering this too! And what exactly made her pass out? Did she swim up too fast? Or just simply lack of oxygen?

Great question. Firstly, it's very rare that a competitor blacks out at significant depth. The reason is that being at depth is like the opposite of being on Everest - you have more oxygen than normal in your blood because of the pressure. However, because you burn a lot of that oxygen while you're at depth, when you return to normal pressure, suddenly your body finds itself with very little oxygen. For this reason, almsot all blackouts happen close to the surface. This is thought to be a natural saftey mechanism of the body, and despite being unconcious, the body can sense when the face is exposed to air again and blacked-out divers usually start breathing again by themselves once on the surface (the rescuers in the video give safety breaths to strengthen the signal to the diver that she is back on the surface). Now, to answer your question, if someone does black out deeper down, the people monitoring will see it on the video and the diver can be pulled up by the rope they are clipped onto. Blacking out at depth is still much more dangerous than blacking out at the surface, because it usually only happens when the diver suffers an injury (e.g. from their lungs being squashed by the pressure), and the diver is much less likely to wake up by themselves. But as mentioned, it's very rare.

@@michaelmccluskey2044 thank you so much for such a detailed explanation!

@@maloneandsloan2137 Здравствуйте уважаемый друг. При погружении на глубины , в любой воде , задерживает человек дыхание . В следствии остановки дыхания - легкие не получают кислород. Воздух атмосферный имеет 73% кислорода в обычных условиях. Организм потребляет из воздуха кислород и выдыхает на 1% менее. Следует постояно дышать. Человек погружаеться под воду ! - происходит задержка дыхания на продолжительное время. Недостаток кислорода в крови - ведет к голоданию в теле и головном мозге. За ориентацию в пространстве человека - отвечает функция головного мозга - можечок.Недополучая кислород - перестает ориентировать человека в пространстве. Дизориентация человека в воде - мгновенное отключение сознания. Каждый аквалангист Советского Союза , кто имел право на погружение под воду с аквалангом - прозодил Курсы ДОСААФ. И только после получения Документа Аквалангиста - имел право самостоятельного погружения.

@@michaelmccluskey2044 Здравствуй друг альпинист !. Вы четко осознаете свой ответ ? Пожалуйста ! - если вы нормальный человек и здесь текст не искажен ваш !- задумайтесь о написанном вами. Как инструктор ранее по подводному погружений в легко - водолазном снаряжении отвечу на ваше, здесь " горе - разьяснение ". При уходе человека на глубину!.- происходит расход кислорода в организме. Давление воды сжимает тело. Обязательным считаеться постоянно выпускать воздух. Мелкими порциями на всем протяжении дистанции..Содержание углекислоты уменьшая. При гипервентиляции на поверхности , до погружения в воду, - создаеться переизбыток кислорода и проявляеться головокружение. Можечок человека ! - отвечает за ориентацию в пространстве. Его нельзя переохлаждать. Второе - головной мозг человека , при долгом нахождении в воде и тем - более на глубине недополучает кислород. Легкие имеют свойства работы в постоянстве для обеспечения тела человека воздухом строгой пропорции - 73% - кислород и 27% - углекислый газ. Как к примеру КИП-10. Это спасательный аппарат для всех судов СССР. Где в регенерации воздуха имеются гранулы в литровой капсуле. Где при поступлении углекислого газа - поглощение его гранулами, и на выходе - 73% - кислорода.

The bends happens when you breath compressed air at depth which expands on the way up.

This is freediving which is basically you have same amount of air in your lung at first start and when going up to surface.. it is not like scuba diving.

Technically it's not because of breathing compressed air at depth, it's spending significant time with air at that pressure in your system. The bends is caused by dissolved gases emerging in the bloodstream as bubbles when the high pressure is released, just like undoing the cap of a Coke bottle causes it to fizz. A free dive is a pretty short (though extremely tough) ordeal and the air in the lungs doesn't have enough time to dissolve into the blood. The analogy would be undoing the Coke bottle, then tightening it again and releasing it just 2 seconds later.

It’s entirely possible to get the bends in freediving. If you don’t spend enough time between dives breathing on the surface, if you do too many deep dives (40m+) or if you spend too long at depth, nitrogen builds up in the blood and that’s what will cause the bends. That’s why taking a freediving course is so important! Safety should always be your number one priority in freediving!

Do you mean the part where she almost died doing something stupid? But was rescued by others enabling her stupid behavior?

​@@FinnMcRiangabrathat's just how extreme sports are, not for me but definitely for them and that's ok lmao

@@crazygur1y You are laughing at someone dying but claim indifference? There is something wrong with your though processes.

@@FinnMcRiangabra That is your opinion. what are you doing watching stupid videos then?

​@@FinnMcRiangabraman shut up lol.

Natalia Molchánova #1 for ever!

Pudieran dar alguna clase por video para aprender un poco

I misunderstood your message, or are you saying you dive 100 m without training?

@@alamos8 Oops, a typo. 100 feet! Slight difference.

@@fredread9216 haha, yeah, units make a big difference:) You would have potentially been a worl record man

Meni nije jasno sta te ovde oduševljava jer ovde rizikuje život za šta.Sta je svrha.

Не рекомендую погружение на 25 метров. Вы входите на 25 и 25 метров выхода на поверхность. Итого 50 метров.Вам надо найти добычу и сделать точный выстрел. При идеальных условиях - крайне - тяжело. Помните об отключении головного мозга внезапно на глубине. Как ранее Инструктор Подводного погружения в легко-водолазном снаряжении - предупреждаю об опасности. Можечок перестает функционировать и отключение головного мозга на глубине ведет к гибели.
