so... the bends: i came up too fast after scuba diving once and let me tell you - going through the bends is no fun. i was sick for about 12 hours. i'd describe it as kind of a cross between a bad hangover and mild food poisoning or the flu. that said, if you want to talk about the REAL bends - heroin withdrawal is about the gnarliest thing the human body/mind can go through. you seriously want to die for about 5 days/nights straight before you start to feel any better. the entire time you convulse, have muscle cramps & spasms, go from hot to cold sweats, shiver, occasionally vomit & have diarrhea, have no appetite, are exhausted but can't sleep, & feel absolutely no joy no matter what. plus there's the initial fear you suffer before the physical sickness overtakes you. just knowing you're going into the withdrawal is terrifying. then once you've made it through the acute phase(about a week) you still go through a few week long depression before you begin feeling what i'd call "balanced happiness" again. And when you sleep, you suffer nightmares called "dope dreams" where you visualize yourself about to get high & right before you do you wake up panicking in your sweat soaked sheets. it's a horrible experience. it's such a hard thing for anyone who hasn't gone through it to understand(although i'd imagine going through chemotherapy is probably worse). I never understood why medical literature consistently refers to opiate withdrawal as "flu like symptoms". I've had the flu a few times, but it doesn't even compare. One doctor i spoke with said that the emotional feelings opiate addicts experience while going through detox is similar to that of losing an extremely close loved one(intense feelings of grief & mourning) - which i found to be accurate. ...don't do drugs kids.

Well.. upon initial read.. I wasn't expecting this to hit so close to home. I would agree, though. I almost feel as though anticipation, or fear, of sickness is more mentally debilitating than the sickness itself, easier said than balls deep in it.. especially if it's a conscious decision and you still have a bit of dope on you. I've never experienced a stronger temptation to ruin progress. I didn't realise "dope dreams" were common! They're really not dreams.. just added agony to torment any chance of a restful sleep all of 5-10min gets you. I know it's your brain trying to comfort itself, and the promise of relief feels so attainable while you're in it-I just never could get the needle into a vein. Right before I had the chance to see blood register I always woke up. During the worst, to make up for that I would do "dry runs"; injecting purified water to try and trick myself. I knew it was false hope but the iota of believability that it would ease any fraction of that torture was enough. Sad, right? People ask "why would you relapse with knowledge that, inevitably, you'll go through it again?" Well, sure your first time will never be as satisfying or euphoric as the first.. but it's still that familiar feeling. A feeling worth feeling again.. until that time does inevitably come. The fourth time finally helped me realise its worth was no longer valuable. Tell me something: have you experienced the near-fatal flaw of dosing buprenorphine/naloxone too early? Precipitated withdrawal? Fuck. It's like condensing two weeks worth of "normal strength" withdrawal into (once) about 3 agonizing days down to (once) about an hour.. I got too impatient the first time. The second taught me my final lesson on that balancing act. I still take subutex. Given its half-life and the horror story coming off of methadone was I'm afraid to stop. I wasted my twenties with that debauchery. I turn 31 this year. I know I can titrate, I did once. I went from 12mg now down to 4mg daily. There are other factors that play a part, but.. hell. I'm sorry, I didn't mean to drone. I somehow got here from the infamous Delta P crab video.. otherwise, interesting learn that the symptoms are somewhat similar!

@@Post.nut_Clarity oh man, you listed a whole lotta truths in that comment. I can relate to everything u said. The fear of coming off dope is so strong that it's practically just as challenging as going through the sickness. Its the fear that kept me on dope. I'd kicked before & knew how awful it was & even though I wanted to quit, I was too afraid. The dope dreams would usually stick with me for a couple weeks or so after kicking. It's incredible how vivid & lifelike they are. It's always right before u get that fix when u wake up. & when u do wake up its almost like u could feel that balloon/bag in your hand, I woke up smelling it, I could almost taste it - & then it's so torturous coming back to reality, waking up with that craving. I personally have never gone through suboxone precipitated withdrawal but ive seen ppl go thru it & it looks horrendous. Ive never seen someone kicking/spasming quite like that. I do prefer suboxone/subutex to methadone just because for me, methadone was so hard to come off of. But subs have their drawbacks too. If u take methadone your first morning without dope, you're usually fine within an hour but with subs u gotta wait almost a whole day without dope before u can even take it. then in my experience I wouldn't b able to sleep the first night on subs & wouldnt really start feeling better until day 2 of taking them. But for me, coming off the subs wasn't nearly as brutal as kicking dope or methadone. Not everyone will agree with me but, I was pretty much starting to feel healthy again after about day 4 without subs. Congratulations on your upcoming birthday. I'm not a tea-totaler who thinks if you're not 100% clean of all substances then u need to go to NA. But you & I both know there's nothing cool, fun, or worthwhile about heroin use.

@@the503creepout7 oh, damn. I was half-expecting no response, especially not so soon, haha. Yeah, methadone was awful. I somehow managed to sleep through the first 72hrs. I was actually somewhat ok after that. One thing I noticed, an area where the kick affected me, was in my voice. I can hold a note/tune well enough and whenever I sang something would induce this undulation, a vibrato of sorts. It felt weird, haha. I couldn't control it and it stuck with me long after the noticeable side effects had dwindled. With the first precipitated w/d something as simple as taking a sip of water that accidentally got into the airway and made me cough had be doubled over, hugging the toilet, puking, and dry-heaving so hard for so long blood finally starting coming up. The intensity was indescribable, man. I was in unfamiliar territory, too, in the middle of nowhere northern NM, deep in the mtns on a seasonal gig. Luckily I was off for a couple days after. Working in a busy kitchen is the absolute worst while you're sick. Doing anything does, really. The feeling of anything touching the skin you're in, that is already crawling.. it always made me laugh internally when I would hear someone say "____ makes my skin crawl".. they had noo idea, lol. It's the only mental state I've experienced where literally _thinking_ of anything other than the use or acquisition of dope actually made my brain hurt. I'm sure it's different for everyone, unfortunately I never gave the very first kick a chance. A week in a friend offered me suboxone and told me how to use it. At the point when it finally started kicking in it was enough to get me pretty toasted. I went from that to a methadone clinic. The thing I hate about sub wd is the slow onset.. it just takes forever, gradually wearing you down. It's not as intense, for me either, but it's still wd. To "hear" it only took you about four days makes me jealous, haha. I would agree. Life would've been better without the introduction to opiates/opioids.. the quality of it, anyway. Someone who was very important to me-very close, ironically who introduced me to heroin, might still be alive. A lot of what if's but the only absolute lies in abstinence of its use. I know sometimes it's unavoidable, medically, but recreationally.. which is where I got my start, sharing 10mg percocet and crown royal with an fwb who got her wisdom teeth removed.. again years later with strippers and oxyxontin.. I would trade it all in. And thanks! Luckily the celebration continues and I count my blessings.. I've already "technically" died 4 times being reckless with dosage. It always cheers me up to hear the story of someone who made it out :) It makes the end goal feel more attainable.

Definitely withdraw is like death. Worse then heroin or opiates in general is methadone withdrawal. That's intense sickness that's miserable for why linger then general opiates bc of its incredibly long half life. Let's just say that my 28 day rehab Detox was a failure and I'm still on methadone 15 years later

I couldn't help but comment this correction cause it bugged me for some reason - It's not air that forms as bubbles, it's the residual nitrogen. At higher pressures, it's harder for your body to dissolve the excess nitrogen so if you go back to lower pressures without letting it do it's thing, it will form these bubbles. And it's a real life threat if not treated asap.

I like the way you make science and educate with enthusiasm. 60psi(pounds per square inch) would be roughly the equivalent of 4atms(atmospheres), not necessary life threatening to ascend from but the actual border limit used for re-creational diving(4atms=132ft..rec dive limit 130ft). Remember decompression sickness has symptoms that your body eventually will deal with but becomes more deadly at deeper depth for longer times, especially on lighter gases(ie:helium).. but your experiment using the pressure pot/pressure cooker to me would more simulate gradual decompression as opposed to rapid or more severe explosive decompression. Nevertheless I like your experiment but I doubt it would be deadly as seen by the limited nitrogen bubbles in your blood.

Can you experiment the effects of a fan/space heater in the vacuum chamber or pressure chamber? See how the air and heat will move throughout the chambers.

Great stuff, if you have the time, could we see a repeat of the experiment with a before shot of the blood sample? Maybe the bubble was present before the depressurization or caused by the jiggle of the equipment?

Yes, this follows Henry's law... Increased pressure underwater increases the solubility of gases in the blood of scuba divers. When the divers comes back to the surface the pressure decreases and this leads to the release of dissolved gases and the formation of bubbles of nitrogen in the blood. This blocks the capillaries and creates a painful condition called bends.. The O2 gas in the cylinder for breathing is diluted with nitrogen gas.. Bcz concentrated or pure oxygen can lead to combustion..

There's quite a few problems with this video. Bubbles forming in the blood *can* be a problem, but bubbles in the blood are typically filtered out in the lungs. In research studies in hyper/hypobaric conditions we induce blood gas bubbles quite often where I work. In multiple studies, we took subjects down to pressure to simulate a dive, then took them "up" under hypobaric conditions to simulate flying, where we then performed ultrasound videos of their hearts to observe the bubbles in their bloodstream. The bends typically is a problem when the NITROGEN comes out of solution in tissues around the body and can constrict blood flow or compress nerves. The nitrogen does not have to originate from the bloodstream because it is typically residing in all your tissues.

I have always wanted to check it myself. Great :) But i wish your videos are longer, you've got great ideas, keep working :)

So I'm assuming the air under water pressure is the oxygen you are taking right?? Does that mean one takes more oxygen per inhale than they would when it outside? Can you take less puffs of air to control this or regardless it will form into a bubble ? And also, the bubbles form as you go from atmospheric pressure to less pressure?

I love your videos. keep up the good work 😀😀

This experiment is wrong. He should tap blood while breathing pressurized air like in a hyperbaric room. Freedivers don't get the bends as they don't breath pressurized gas.

watched a video about the saturation divers who technically exploded from rapid decompression. reminded me of your channel. thinking about when you release the vacuum in a chamber too fast and everything goes flying around. but on a giant scale with humans inside... 😬😬😵

Starts at 2.00 if anyone wants to avoid the “hands”😊- it was good but if you google the bends you will learn more about nitrogen.

The nitrogen would be taken into solution with the blood by breathing the compressed gases at depth. Compressing fluid blood in a test tube would not matter without a way for the nitrogen to get into solution. The nitrogen would be taken into solution with the blood by breathing the compressed gases at depth. This could be done using a recompression chamber. The blood would need to be extracted once the test subject had reached the approprtest depth depth. The fluid could be retained at pressure in a paSs-through feature while the test subjects were returned to ambient pressure. The experiment could then be conducted by rapidly decreasing the internal pressure to ambient.

Can you put a Drone in to a pressure chamber?

Amazing experiment, even though it's not quite theoretically replicating the bends. I do however imagine the reaction would have been even more noticeable if the blood wasn't coagulated.

Would if divers have to do an emergency ascent and don’t have time to stop on the way up to decompress ? Like if they ran out of oxygen

Interesting experiment. My guess is that the bubbles at 60 psi (approx 131 feet underwater) would be worse for a diver in a rapid decompression scenario. I would thing breathing at that depth would result in a bit more nitrogen dissolving in the bloodstream (assuming a 80% nitrogen blend of compressed air is used).

I was kinda hoping it was gonna froth up like a saturation divers would

Huh, it'd be kinda neat to meet you! Unfortunately, I'd have to travel a huge distance, and I don't know if I could even earn enough money fast enough to make it.

Okay its been mentioned a few times in the comments but just in case.. So the bends is not at all what he demonstrated, in fact he didn't really show anything. Ill explain. When you dive, you're not breathing in pure oxygen, you're actually breathing in mainly nitrogen mixed with oxygen. Now, when Nitrogen is under high pressure, it compresses naturally. When you breathe in that compressed nitrogen, it goes into your blood stream, as expected. This is all fine and dandy but if you ascend too fast, then your body wont have time to dissolve that nitrogen all of that nitrogen in your blood will expand and cause bubbles of nitrogen to form around your joints and cause all sorts of other problems. The way to treat it is to go into a decompression chamber as fast as possible. A decompression chamber is a pressurizes chamber that you sit in. The pressure within the chamber will cause the nitrogen in your blood to compress back down to the size it was when you were diving and your body will dissolve it like normal. Its a nasty little condition and its disappointing that this channel didn't really do any research and showcased pretty much nothing. The guy who runs the account is a smart man no doubt but he should have done more research

Blood has got the bends, oooh yeah, i dont have any real friends

“Have they all got the bends?”

The amount of bubbles that you showed I seriously doubt that that would have much effect as your bloodstream does absorb some amount of air all the time.

Why do the little air bubbles form? wheres the air from? - 3:00 my bAD, when it was pressurized the air was able to dissolve more into the blood more than at atmospheric pressure.

Okkaay!? K-9 0Ut.. keep up the good work 👏

The only thing I am confused on is the ata that is 14.7psi which is 33fsw is already in there so I am not sure if I add that to the depth. Yeah I don't think I do so 134fsw which on that table and schedule you would put you at 140/15 if that was his Bottom time. You owe 5mins at 20feet for a decompression stop on air. 3 mins for 100% oxygen.

Well yes and no. At altitude you can cross Haldanes Line of 18,000 feet. This is the altitude where nitogen comes out of solution and could form bubbles. But the bubbles are microscopic and can't be seen by the naked eye. It becomes a significant risk at altitudes above 25,000 feet. And the higher you go from there the greater the risk and the greater the bubble size. But still, they're too small to see unaided. What was demonstrated was ebullation. Where the atmosheric pressure is less than the surface tension of the liquid, the gas ebullalates from the liquid in the form of bubbles. In this demo. You super saturated the blood with air and overcoming the surface tension and forcing the gas into the liquid. This is done by increasing the pressure in your mini hyperbaric chamber. When you released the pressure, the air that was forced in came out as gas and bubbles. You didn't see many bubbles because the surface tension of the fluid was still under the pressure of the atmosphere (14.7 psi). A better demo is to take a container of water in a hypobaric chamber and decompress it to 63,000 feet. This is called Armstrongs line. There fluids at 99 degrees (f) will ebullalates the trapped gasses held in place by the surface tension of water (47mm of pressure) is greater than atmospheric pressure ( Same concept...but not truly nitrogen bubbles with you example but it make the point.

wow.

You need a larger amount of animal blood or water wis water with food coloring and a better valve like a dump valve

My skepticism arises from this: the blood was not absorbing air during high pressure in that chamber, as a diver would while breathing compressed air. I don't see how new gases could have been dissolved into the blood to emerge when decompressed. That is, unless hemoglobin will absorb oxygen directly out of the air, but I find that unlikely.
