29:36 -> We actually did this experiment at Uni once (I'm studying biology). Well not with scuba diving gear but with the same premice, basically seeing how our bodies reacted to air gradually being enriched with CO2 as well as running out of oxygen without increasing the amount of CO2. It was quite interessting to see how fast your body reacted to an increase in CO2 levels and how you had no idea that the O2 levels decreased when CO2 levels did not increase. You could one second breath normally and the next pass out an die without ever noticing something was wrong. (obviously we were under supervision the whole time to make sure that does not happen)

We did the experiment where you constantly add 17 or something and meanwhile you dont get any oxygen. You see that at some point the handwriting gets kinda skewed and of course the sum will be wrong or a number will be missing or something like that. The person suffering from hypoxia was not aware at all that anything was wrong and even for the observer the point it started was kinda gradually. It was a very interesting experiment.

I totally get it; I'm one of those people too. Before I met and fell in love with my first dog, I was planning to do a dive course. I'm glad I didn't because so much can go wrong especially when your mental faculties are also at risk. That's a deal-breaker for me so I'll stick to the simplicity of free-diving and snorkeling.

I had a hypercapnia experience on open circuit a few years ago. It was terrifying. I was working way too hard in cold water (around 50 F, diving wet, finning and breathing hard to stay warmer, which I no longer do) at around 120 feet. At first I felt slight nausea, but it quickly progressed to rapid breathing, racing pulse, and feeling like I just couldn't get enough air. My body wanted to bolt. I couldn't catch my breath. Panic was coursing through me. My air seemed bad somehow. It really felt like I was going to die. I was solo diving, so I had to sort all that out on my own while trying like hell to just keep mechanically breathing deeply and slowly making my ascent, which I did by staring intently at my computer and the sandy slope in front of me. It passed in a few minutes of really slowing down and breathing deeply. I would wager that being a bit narced played into the whole mental situation. I wouldn't recommend it. 😂

I used to do hard hat diving and a few times my hat would fog up due to my breathing cycle. Thankfully with hats we have a free flow mode. So after a while if I was doing heavy demand stuff, I just cracked it open and let it flow since I had an "unlimited" supply due to it all being supplied at the surface.

Woody, one time I was having issues lighting the pilot light on my water heater. I had done this many times before no problem. …..well this time , it wouldn’t light. I kept trying over and over. I was getting gassed without even realizing it. The more gas I inhaled, the more I felt stuck in a loop . I became even more determined to light that damn pilot light! It was strange. I can’t believe it but I didn’t realize in the moment what was happening. Evening though I’m very aware that it could happen. It effects your brain to where you deny it . It’s so weird. I was stuck in a loop of lightning the light. I felt very stubborn. At some point I gave up . Walked back into the house from the garage. Still feeling stubborn and stuck, I didn’t tell my husband that I couldn’t get the light lit. I sat down. My heart was racing. I was breathing heavy to try to slow my heart down. Finally it hit me what had happened. ..the interesting thing was how I was stuck in a loop doing the same thing over and over. And I was still thinking I was in control even though I felt different. It crept up on me. It sounds weird but I find that the be such a valuable lesson to me. I now sorta of understand how it feels to have this happen. To where as before I just thought it was a black and white issue. I feel normal, now I feel bad. But it wasn’t like that immediately. By time I started to realize what was happening , I was in too deep. Luckily , I stepped away and went inside. It took a good 30 minutes to an hour for me to feel normal again. I feel strangely lucky to have experienced that and be ok.

Called my ER physician friend about this. He told me two things: 1) often times people with elevated CO2 don’t feel like they’re getting air despite accelerated breathing (maybe why Kevin claimed that with the safety diver’s alternate), and 2) if this happens you want long exhales to really off-gas the CO2…really empty your lungs on each breath.

@dr.earbeastuniversity5275

2 жыл бұрын

This happens because hemoglobin has 4 binding points which usually lock o2 in, when you get CO2, it binds to one of your points, and cannot be removed via your body's normal trick to displace the oxygen where it is needed. It causes you to feel as if you're suffocating because even though you have air in your blood, it can't be released (this will actually cause your blood cells to break down as well and form a new toxic compound that your body can filter over time). Extremely watered down, but 1) is very true. Long exhalations DO work, but it can be hard to remember that in highly confused states, which is usually where you will end up with CO2 poisoning because of the panic of the suffocation feeling.

@1985rbaek

I was about to write something similar. Fast breathing happening for the guy in the vid are shallow breaths. Meaning that the lungs never really get rid of the CO2 build-up, only replacing a small portion of the air. Your body is saying you already have to little air, so a long exhale is the last thing your body wants you to do, the one thing that would fix it. I think it is the same reason panicked divers sometimes forget to exhale in a torpedo (uncontrolled) ascend and blow their lungs. Firemen (Smoke divers) here were taught to do something called skip breathing, that can save air and calm you down, which is 2 inhales per exhale. This was shown to build up CO2 levels, so the method was changed to long inhale, 3 sec pause, long exhale, 3 sec pause, repeat. This reduces heart rate, but does get rid of the issue of CO2. This is something similar to what biathlon (ski shooting) athletes are trained to do as well.

Thank you Beth!

When you breathe, even normally. you only exhale about 10 percent of the air in your lungs. When taking shallow breaths this is going to be even less. So it takes many breaths to replace the total volume and then you are basically trying to clean a bucket of dirty water by taking out one cup of dirty water and then putting one clean cup of water back in and repeating the process. The water will get clean over time but you will have to move many more cups than the total volume of the bucket. Hyperventillating in this analogy is like using the smallest possible cup to move water back and forth as fast as possible, when what you really want to do is is empty out the bucket in one go and completely refill it. To be clear that is why your CO2 levels will continue to rise even after bailing out, even if you could instantly completely swap out the air in your lungs it will still take sometime to clear the excess CO2 in your bloodstream, think of a runner who's just run a long race, he is going to continue to breathe hard for a while even after he's stopped running.

If you want to try to tackle this; - gradually learn to use a scuba mask in a pool, putting your face under water, getting deeper over time - work with a dive instructor to have a longer time to get used to the dive equipment in the pool classes, then in a very shallow open water dive (maybe even only chest deep water to start) - next open water class would be deeper - ask the instructor to take their time teaching you and practicing mask clearing and calming techniques - have caring buddies who stay very close and encourage you - depending on your progress, maybe only do shallow (30 ft.), high visibility, warm water dives in calm conditions with trusted buddies I've seen people do these steps and progress to where the claustrophobia, at least while diving, totally goes away.

My 2 cents, as a rebreather diver who has experienced a CO2 hit: once you bail out to open circuit your CO2 level is not going to increase, but when breathing VERY shallow rapid breaths you aren't getting rid of the existing CO2 very quickly. It's not a function of being on the loop vs OC, even on the surface it would take a significant amount of time to flush that CO2 out of your system.

Жыл бұрын

​​​@@E_Clampus_Vitusit's because CO2 sensors aren't reliable enough right now for rebreathers. It's in the video where Gus mentioned that question and what Mike Young said about it.

Hello! I am a respiratory care practitioner who is also a diver. So you are right! Carbon dioxide acts as a trigger to ventilate because we possess chemoreceptors in different areas of our body that react to oxygen, carbon dioxide and hydrogen (hydrogen ions being the main source of ventilatory response. Carbon dioxide possesses a value of hydrogen ions so you can argue that the reaction to carbon dioxide is secondary). Oxygen, in one reaction, actually works as a mechanism to dull chemoreceptor response to hydrogen ions, therefore, switching to a lower percent oxygen or higher percent oxygen at a given level of hypercapnia will have an inverse relationship with your respiratory rate (lower [oxygen]=higher resp. rate, higher [oxygen] lower resp. rate) but this mechanism I have not seen in action in healthy individuals, but is pronounced with people who have chronic lung disease. Sorry to be writing an essay, but to answer your question on building CO2 while working to eliminate CO2 can be answered in terms of the degree of increased work of breathing vs ventilatory support. So if your work of breathing is greater than the amount of support you have then you will go into respiratory failure (Our natural support is our muscles of inspiration i.e. the diaphragm, internal intercostals). If your support is equal to or outperforms your work of breathing your urge to ventilate and work of breathing will tend to diminish after 5-10 minutes as the doctor was saying (assuming you have no chronic lung disease or anything like that). So since the only airway support you have underwater is your regulator and muscles to inhale, if you have a CO2 hit AND you also have venturi/rotator knob adjustment then that may help relieve some of the work you have to produce with your muscles alone, although I haven't heard anything to support this. But after analyzing many blood samples from patients with acute non-chronic hypercapnia, I can get a high level of CO2 (PaCO2) initially and after I put them on a BIPAP or invasive ventilator I will usually see a reduction to normal levels within 10 minutes. I hope this helped and I didn't butcher any explanations. Oh and also. Woody and Gus, love your videos, they definitely have made me a more conscious diver. Don't change a thing. You guys rock and looking forward to the next dive talk trip!

Maybe a link to the video where you talked about what to look for when finding an instructor would be good or even another focused vid just on researching the correct training you need.

I was just thinking out loud.

20:18 He does have “normal” sized bailout tanks, they say it, but doesn’t get to it. For some reason they aren’t carrying their bailout tanks on them, but must have tied them to a line or something. The thing is, on every rebreather you can bailout to your diluent and use your rebreather on open circuit breathing directly from your diluent without having the gas loop through your scrubber. Usually you’d use this function as a mean of having something to breath while your sorting out your bailout tanks, or if your near the end of your dive, close to the surface and without any more deco to do, as your diluent usually is contained in a very small tank, usually between 2 to 4 litres, and as such is used very fast. It’s the same principle with the kiss rebreathers Woody and Gus use, but their diluent is contained in a bigger tank.

Not a diver but your videos are soooo interesting. I geek out on science. Plus I’m too terrified to ever dive. I live vicariously through y’all.

Love the explanations guys, every video is amazing. My favorite KZread channel right now by far.

I've known individuals that did this, or variations thereon. But I'd never heard of anyone actually teaching it. A lot of folks will push the duration on a scrubber somewhat, with seemingly far better results. Though it's still a roll of the dice. About breathing under higher CO2 you can't entirely fight it, but with focus you can adjust to taking deeper somewhat slower breaths. It won't really reduce your gas consumption in the moment, but does seem to help get back to a normal pattern a bit faster. And yes, you can get CO2 buildup on open circuit just like on the surface when you're exerting. You can go through a lot of gas, and get to breathing so hard you try to breathe more than the reg will deliver. When working hard underwater you need to take more and more frequent breaks to help stay out of that zone. Areas of "bad air" high CO2 also occur in dry caves and can be dangerous, though in most cases the symptoms are easy to spot. If you want to experience that, there's nothing that says you have to be in the water. Easily accomplished on the couch, and much safer.

That's crazy, i had no idea how rebreathers worked or that this could happen. That fella is lucky he had his team there!

Im a secondary teacher from the Uk and im absolutely hooked on your videos . I played and incorporated some segments from your videos into my lesson planning and my year 10 students are hooked to . Thank you for this awsome content 💜

Oh man I’ve been watching you guys for a few weeks now. After my CST certification I’ll probably be going to go for my diving certification because i have learned so much through you two and now I’m obsessed!! Cant wait to see this channel blow up! It’s only a matter of time now, you guys have brought so much joy and laughter in such a short amount time😂 thank you for everything you do!

Thumbs up for getting opinions and references from the specialists when needed.

That almost went from a practice body recovery drill, to an actual body recovery drill. He was surrounded by all The technology and help one could ask for. If he was diving alone, or diving with just one dive buddy, he would probably be dead.

Best kind of safety training for anything needs to give people a good enough functional understanding of the chemistry, the mechanics, or the physics of what they're dealing with that they can't just invent their own seemingly "smarter" protocols for how to operate the device. If they had been taught the sorb reaction progresses as a single layer throughout the scrubber they'd have known that mixing it all up was just as bad as poking a straw through it.

Sometimes tweaking it on your own as necessary. Protocol was to mix it back in 2004 in this video. That is how the experts taught people how to do it. These divers anyway and I'm sure they're not the only one. It takes time to figure things out and unfortunately the first people in a new technology or even way of doing things are simply Test Dummies. You have to know what not to do before you know what exactly to do and you learn that through trial and error. Unfortunately rmd through manufacturers doesn't always do a thorough enough job and the consumers are the ones figuring out the details for the producers to tweak. Sometimes when you have a few hundred devices out there being tested doesn't give you the full picture until you have thousands of them out there being used in real-world everyday scenarios

Everytime I watch one of your videos I get more educated and the world of diving which I love so much but I haven't had the opportunity to dive in many years but I still love learning more so your videos are very helpful when I do dive in the future. Thank you for these!

Woody: *asks question* Gus: "I read your mind, and I have the answer you seek." This is fascinating stuff that even non-divers like myself can enjoy. And Woody will be pleased to know that 3 months later, this video still has no downvotes (I can see dislike counts on videos with a browser add-on).

Hey guys, I had an interesting conversation with my dive instructor about the kids being rescued in that Taiwan cave a few years ago. I would love a video from you guys about what happened there.

When in doubt, you must bail out! 💯 Not a bad motto in general, but seems spot-on for rebreather divers. 🙂 Great episode guys! Very interesting and informative, best rebreather seminar ever! 🤓👏 Without Dive talk, I'd have no idea what a KISS rebreather is... instead I can explain how one works, and what mistake to avoid when packing one's scrubbing cannister! AND, I know how KISS rebreathers differ from others. 😁🤘Hope KISS are makin' it rain up in there for you two ambassadors. 💸💰👍

Great video! I love watching presentations on the physiology of diving!

Wow those guys were trained/taught to keep old scrubber and save a few bucks 🤦🏼‍♂️. Gus “Just repack it bro” I knew absolutely nothing about rebreathers before watching this video. Although technical, I still found it very interesting. 👍🏼👍🏼

I have been binge watching these videos for the last week i have no interest in diving but dang i just love watching you guys and learning about all of this but it has definitely reassured me that I'm never getting in the water again lmao i hope you guys always stay safe we need yall here making these video's keep up the great work guys :)

29:20 If you want to feel a CO2 hit then all you need is high intensity exercise for 20-30 minutes. 20 hard mins on a bike your SAC rate will go crazy, your lungs will be screaming and you'll be gasping for air thinking you might die.

On submarines you can tell if the CO2 is high and you can tell when the just added oxygen

Why does it seem the victim is downplaying the entire incident? It almost appears he is in denial about how bad a situation he was really in

I'm not a rebreather driver, but I have had asthma since I was very young. One of the things I learned early on was that quick, shallow breathing doesn't get oxygen in your body; and the most important thing to do when having an asthma attack is to breathe as deeply as possible

@Musiknird

2 жыл бұрын

Goes for many situations in life like if you get a severe panic attack also slow and deep breaths is the key to calm down and help to get the panic attack under control. We can help our body in many ways by just trying to be calm and breath. Now I don't have asthma but I used to work as a paramedic and met many patients with asthma and its really hard to see a person struggle so hard to breath, but I'd like to remind everyone that has asthma to always have their inhalor with them at all times. Even if the inhalor might not help completely sometimes and the patient need stronger medicines and treatment it will help to improve and the person struggling with breathing difficulties and make it a bit easier for them until the ambulance arrives. I hope you are ok!

So glad this was a recommended video, and found your channel. Watching all of them lol, thank you for your experience and advice. I am fascinated, but not a diver. Stay safe guys!

been on a binge and man i love these vids guys. DONT STOP.

Guys I love your stuff, I think diving is about the most Rad thing you can do, but God knows I will never do it!! Be safe under there🤙🏼

15:05 perfect moment for Gus's traditional comment about 🍌

46 breaths a minute...the average is 12 - 20...anything above 25 is classed as laboured and cause for concern. And resusing the powder? Pfft, just shows how much SKY value their staffs lives to save a couple of quid. I love how woody says "you swarm em" 🤣 I'd appreciate being swarmed by my dive team if I was struggling, I'd feel taken care of and not alone. Pure teamwork💪🏻 Another great video guys! I loved it.

If the other divers are still on the loop of the ccr it’s hard to do an oral inflation. So they need to get of the loop first, go in to OC or BO mode and then inflate the buddies bcd. Experienced divers will maybe able to manage that without going OC but this is beyond my level

You can experience a CO2 hit without having to risk it in a pool. Just breath into a sealed plastic bag and keep breathing in and out without letting any fresh air into the bag. Within 10 to 15 breaths you will already start to feel the effects. Your body will already start wanting to pull the bag away to get fresh oxygen into your system. And then you realize even after you take the bag away and do breath fresh air, it takes a few minutes for the effects to go away.

You would need to keep breathing like that far FAR past where your instincts are pulling the bag away for you in order to come close to passing out. You won't pass out. And even in the small sliver of a chance you do, your hand falls away from your mouth and your breathing oxygen again. Do you panic everytime someone breathes into a paper bag while having anxiety and tell them they are going to die ? Relax. You can do things safely within reason that doesn't put you into danger.

So why didn't the two people that were with him when he switched over to his tank immediately take him up? At that point he was surely in trouble. Sounds to me like he doesn't like to take responsibility for screwing up. So it didn't get him this time, but if he doesn't rethink his training; it will.

You would think they noticed him switch over. So they should have a policy to then immediately start a rescue and safe surfacing.

I can see by your facial expressions you were thinking this too, but this guy has a huge ego. Refuses to admit he was not in control after the co2 hit.

@harrisaxer2651

2 жыл бұрын

I'm not convinced it's his ego talking. My understanding is since he confesses confusion, and probably guesses that he's hit, he then tells the story of how that hit did not allow him to think straight, therefore keep believing that he is in control of the situation even though he clearly isn't. And he says that probably to emphasise how grave the situation really was for him. That's my opinion

I know nothing about scuba diving but these guys are awesome and so entertaining to watch

Best channel on KZread! Hope you guys smash 1 Million very soon!

Pretty scary how the diver is so adamant he was in control even after all the facts and expert opinions are clear. Almost seems prideful or egotistical, cant say i made a mistake (reusing scrubber), and didn't have proper equipment (proper size bailout tank). One thing your channel and Mr. Ballens have tought me: ego and diving doesn't mix to well 😆

15:47 this segment is what i was mainly pointing at about "ego". He still seems convinced it was a controlled ascent. Being in a haze from C02 and running out of your own air, relying on two different divers air (he even rejected a good air source from panic) doesn't seem so controlled. I dont even blame him for the accident, this video made it clear that there was a problem with the teaching/culture of diving at this time and region (the shocking number of divers that thought reusing sorb was a viable option). Point is: Just seemed like he was downplaying it (saying he was in control), which i attributed to ego. Just my worthless non diver opinion tho 😆
