after 60 meters you need helium and nitrogen, so thats why he has so many tanks

@grig24x You mean after 56, because the partial pressure of oxygen reaches 1.4 at which stage it then becomes toxic and can result in CNS toxicity leading to convulsions.

@wootlegion breathing 21% oxygen is toxic at 56m or deeper.

@whielyex the body is 70% water which we all no cannot be compressed.

@LilBailz69 Sorry, but no. The nitrogen becomes a powerful drug at that depth, not the oxygen. In fact, the tanks have more oxy than at the surface

@LilBailz69 i mean 60 feet. lol

@wootlegion Sorry, but no. have you ever heard of oxygen toxicity?maybe look it up to get an idea of why your wrong.but basicly heres a run down….oxygen makes up roughly 21% of our ‘air’ and is also one of the most plentiful elements in the atmosphere,our bodies need oxygen during metabolism.because of this it generally isnt a concern,when it comes to decompression.HOWEVER there is still the chance of oxygen toxicity, which, you’d generally hear of in one of two forms.one of which being

@wootlegion pulmonary oxygen toxicity,which results from a lengthy exposure to a PO2 greater than 0.5 bar/ata (we generally breathe at 0.21bar/ata at the surface) .even at 40m/130 feet,the PO2 is around 1.05bar/ata it would generally take over 12 hours before pulmanory oxygen toxicity symptoms occur,so it is of less importance than CNS-but is still toxic.OR CNS oxygen toxicity (central nervous system). breathing at less than 1.4bar/ata is considered acceptable when it concerns CNS toxicity,

@wootlegion however between 1.4 – 1.6bar/ata falls in a contingency range thats acceptable for decompression.
CNS oxygen toxicity produces symptoms include tunnel vision,blurring, ear disturbances,nausea,twitching,irritability,vertigo and the major,convulsions.generally,convulsions arent a big deal.however under water they may cause you to drop your regulator from your mouth and DROWN.

who taught you to dive?

@GRolla101 Dry chamber dives have bee done to over twice this depth, experiments on mice have been done to over 8000 fsw, pigs and goat at 6,000 fsw, I believe the human body can survive even a mile underwater if the right technology is developed

omg. it takes hours to get back up… endless safety stops

@cbohar84 i dont doubt it,however i dont believe that we have found that techonology yet and until then we are still at risk,if we try things like this video

WOWWWWW! no top comments ok here I go….im stupid

I used to do that until I toke an arrow in the knee.

they should have had a chair for him to sit in at the decompression stops.. he nearly had his face broken with the bar he was hanging on when it move violently. next we will hear about some dumb – a – hole trying to pull this off wit one tank. i wish they gave more info about air used,stops,etc…did he hit a recompression chamber ? how cold was the water ?

@grig24x his tanks were not marked for nitrox or painted green and his regulators were not made for the Nitrox air mix so i am willing to bet he was on regular scuba air ???

I can freedive this… lol

um… negative… good luck surviving past 200 feet on air… this dude was lucky if he was breathing 5% o2 in his trimix.

on the way down…bunch of times clearing his ears. on the way up… many safety stops ;S
i pass.

I wonder what fish he put in his PADI log book.

lol his hole life deepened on that 1% oxygen like hes on life support but good job also i wouldnt have done it open circuit

@lgttb1 cant go deeper than 90 meters with regular air as the partial oxygen pressure will exceed 2.1 POP which is toxicity limit he will be breathing poison after this, normally we go with 1.4 POP maximum 1.6 in case of emergency.

@DrummerCayden Wow, fail.

Anyone who thinks that this diver could be saved at this depth by just “reeling” up the line he is holding is gravely mistaken..
