Is it physically possible to hold a breath that long?

and live?

David Blaine sets new record on Oprah. 17 min 4 secs.

I'm skeptical.
 

Discussion

Physics news on Phys.org
If he wasn't known for his magic and his illusions, I would have less doubt.

17 min is a long time.
I've read up and it sure as hell seems legit, but I , ... damn that's a long time.

I was very doubtful at first, also because he is a magician. But it seems that this is not his first attempt at all. Besides, you must realize that he took pure oxigen for about half an hour before. So this does not compare to other records without such pure oxygen taking, which are limited to less than 8 minutes (different world record).
 
This audio clip is really interesting, it's Penn and Chris Angel discussing Blaine.

sadly the link leads to nothing connected to Blaine or I missed it.

got it
Thank you. long listen. I tried to hold my breath. :)

Stupid retard! hehehe said with respect. LOL
Slightly off the topic, but nice background to the person.
I like his street stuff but

can a human do this? Is it real or illusion? 17 min is a very long time.
 
Well, several people have mananged more than 16 minutes in the past (mostly free divers, they tend to be very good at holding their breath), so 17 minutes is presumably also possible.
My guess is that someone will break this record within the next few months.
 
It is difficult to fake something if there are observers with you on the stage. Anyway, Blaine is known for doing real stunts. I believe he did this. Here's a link that discusses it: http://www.time.com/time/health/article/0,8599,1736834,00.html
 
People, if you have a thin tube threaded up your anus and and up your digestive tract and pushed down into your lungs, you can probably stay underwater for a very long time, as long as you're getting a steady supply of oxygen. I suspect trickery, not physical capability.
 
Considering that 5 min without breathing is the generally accepted cut off for high risk of brain death, 17 min without some trick seems highly implausible. David Blaine is a well-known illusionist, so there probably is some sort of trick to this (though I'm giving a big "ICK" to turbo's suggestion :smile:). I tried watching for any signs of movement in the video clip, but it was rather short to determine (how many times did he raise his arms? I'm wondering if that was a cover for taking a breath).

Can those claiming that others have reached 16 min before support that with any sort of credible reference?
 
i once held my breath for 30 seconds in our local swimming pool...so maybe he did do it...YEH GO DAVID GO DAVID!

I am not sure how credible it is, but one example:
http://www.apneamania.com/code/worldrec_main.asp?typeID=spr&specID=amap

The discipline is known as "static apnea with pure oxygen". I saw a documentary about the former world record holder, Peter Colat, on Discovery a while back (at least I think it was him). Note that most of these guys are not "normal", their ability to hold their breath being a combination of genetics and a lot of training; meaning it is hard to say what is really plausible.
The record is without oxygen is over 9 minutes which for normal people would probably cause permanent brain damage.

For the record: In my view these guys are all crazy.

Edit: Using Google Scholar I found this paper (free access)

Crazy ! hehehe - sure, for a given value of crazy.

So, some say fake, some say plausible.

Can a definitive answer be determined?
Does illusion fake out physiology? And the World record people?

I didn't watch. I figured cameras would be nothing more than adding to the illusion.
Or stunt.
but what was it?

You raise an interesting point there MB. Okay, I am going to make an attempt to be a biologist, but forgive me if it goes horribly wrong! :blushing:

Would inhaling pure oxygen for half an hour alter the concentration of haemoglobin in the blood, or is this too short a period, maybe I am missing the point of the pure oxygen!? If so then would this not increase his ability to hold his breath? Surely training at high altitudes, which is known to increase the haemoglobin concentration also play a vital role in holding your breath? Is this not what some top athletes do?

Anyway, that aside, I have sound an interesting link. It goes over how to hold your breath for long times, using Blaine as an example. it also says that it is not uncommon for people to hold their breath over the 5 minutes you have said!

That isn't true at all. The "5 minute" figure is in reference to the oxygen supply being cut off from the brain, such as when the heart stops beating. Just because someone is holding their breath doesn't mean their brain is being deprived of oxygen. If that were true, you'd pass out within 2 or 3 seconds of holding your breath.

I'd say that 17 minutes is certainly possible, and every bit as impressive.

No, it's not from when the heart stops beating, but from when breathing ceases...for example, time underwater in a drowning case. Granted, there may be some leeway for air in the lungs vs lungs depleted of air, but it does not require the heart be stopped.

As I already posted, if someone has credible evidence from a source other than an illusionist that it's possible to hold one's breath that long and survive, they need to provide it, otherwise the default is that it is an illusion. If you ask me, his hair doesn't even look wet upon emerging from the water (at least not until he tips his head back an extra time to wet it on the surface water). For all we know, that sphere he was in was designed to disort and hide the fact that he was in an air pocket in the middle.
 
Moonbear said:

You can't be serious. If the heart isn't beating, how do you expect oxygenated blood to reach the brain?
 
Holocene said:

Of course if the heart isn't beating, oxygenated blood isn't reaching the brain...that's not the point I was making. You were arguing that the heart not beating is the requirement...I'm pointing out that NOT BREATHING is sufficient, it doesn't require going so far as the heart not beating. If the heart is not beating, it's a given that breathing is not occurring, but the converse is not true. One can cease breathing while the heart continues to beat, yet the blood is not being oxygenated, so while blood is reaching the brain, oxygen is not.

I think that what happens when you inhale pure oxygen for a certain time is that you saturate all of your tissues with oxygen. It might be that the stock of oxygen so accumulated can slowly get back in the blood during the dive.

I can assure you that breathing pure oxygen for a few minutes really gives you the ability to hold your breath "comfortably" for a longer time than usual, as long ago I tried this. As to whether this is just a suppression of your urge to breathe, or gives you the ability to keep it out any longer, I don't know.

Also, the problem I have with this kind of stunt, is: where does the CO2 go ?
 
I strongly doubt that he legitimately held his breath for over 17 minutes. Navy Seals cannot come close to 17 minutes and they have incredibly rigorous training.

Maybe he used something like perfluorodecalin. (look for images and you can find a mouse breathing in the liquid)

Honestly, 17 minutes is way too long and we have to remember that he is a magician.

I know what youre referring to, I've seen that video of the mouse on the Science channel :) The thing about that however is that I remember the mouse having to take rather strong breaths to force the liquid into and out of its lungs. If that was the case here wouldn't we see his diaphragm working extra hard?

Chris Angel says it's fake. Claims he did the trick several years ago and "held" his breath for 24hrs.

Chris Angel. :rolleyes:

He's the one that is fake. Full of camera tricks and actors. :rolleyes: So obvious half of the time. :rolleyes:

Sounds like you're trying to downplay the stunt. Even with a half hour worth of pure oxygen, I'd like to see an average person hold their breath for more than 5 minutes, which I know won't happen. Nevermind 17 minutes! Please. :rolleyes:
 
I would love to see a poll on this. How long can you hold your breath? But I don't know how to create one. Anyone?
 
Slow Down, There

if an average person merely hyperventilates for a few minutes, blowing off CO2 and hyperoxygenating their blood (although the accumulation of CO2 is the vital factor here), they will find they can EASILY hold their breath for five minutes, or a little more--- and that's with no pure oxygen at all!

I was only skeptical. We have a very diverse group here and the hope was that someone
would know something about the topic.

It's not an issue worth arguing about my friends.
It's just an illusion or a stunt. And a pretty good one too, either way. :)
