13:31 At a lower pressure, there’s a lower number of oxygen molecules entering your lungs. So a lower pressure means your body needs a higher concentration to get the same number of molecules per breath.

[@wallymurray620]

[@danielbudney7825]

More specifically: oxygen in your lungs isn't accomplishing anything ... it needs to diffuse through the membrane of the alveoli, and your blood maintains a certain saturation of oxygen. Membranes aren't magic, and oxygen will pass both ways (the same as carbon dioxide passes both ways) until an equilibrium is reached. The partial pressure in the atmosphere matches the saturation needed in your blood for you to remain healthy.

These are often seen in mountain climbers and can range from mild to severe, even for experienced climbers.The most dangerous are high altitude pulmonary edema (fluid in the lungs) and the even more serious high altitude cerebral edema (fluid in the brain). Both can be fatal. Of the 17 climbers who died on Mt. Everest in 2023, 10 of them died from either pulmonary or cerebral edema, including several experienced Sherpa guides.

As for the oxygen concentration question: simple answer is its not the pressure at all that matters. It's just how many oxygen molecules collide with a blood cell or whatever in a given time. Higher total pressure eg adding a bunch of nitrogen does nothing because nitrogen doesn't do anything when it collides. Higher oxygen pressure means there are more of those available.

[@snowballeffect7812]

Nitrogen can actually dissolve into the blood fluid. This is what leads to decompression sickness, or the bends, when pressure on the body is reduced rapidly. Increasing pressure doesn't necessarily mean you're only adding nitrogen. Compressing the gas can also do this, which basically just means more collisions per time period, which you mentioned, so higher total pressure does increase partial pressure of Oxygen, as well. The opposite is also true, which is why we get altitude sickness as partial pressure of oxygen goes down because total pressure is going down. The reason partial pressure is more important than percentage of volume is because what's important is that number of collisions over time. Low pressure with 100% oxygen like in the first space missions as mentioned in the video, practically leads to a similar rate of gas exchange in the lungs as high pressure and low oxygen. I'm guessing this is what you meant by adding nitrogen, in the context of diving, but that mixture actually has increased oxygen. Too much oxygen is toxic because oxygen, well, oxidizes, so there's actually a depth limit for nitrox gas mixture so the divers' don't get toxic blood. The reason they increase oxygen is because nitrogen and other "inert" gases with the exception of helium (and apparently possibly neon), has an anesthetic effect on the body for reasons that aren't fully clear, since it's hard to study. Speaking of helium, since we know it doesn't have such an anesthetizing effect, we actually use that for deeper dives.

[@oriongaby]

Partial pressure of O2 in air is more important because when you have a gas interacting with a liquid (blood), the concentration of said gas in the liquid will be proportional to the partial pressure of the gas. So for the O2 to properly diffuse trough the respiratory membrane in the alveoli, the alveolar air has to have a higher O2 partial pressure than the O2 partial pressure in the venous blood. The gas exchange process does not use any energy, it follows a concentration/pressure gradient. In other words; ppO2air has to be higher than ppO2blood for O2 to diffuse into blood.

[@GeraldH-ln4dv]

And the exchange also goes the other way with fluid buildup in the lungs due to low air pressure-caused pulmonary edema, a common symptom experienced by high altitude climbers, along with cerebral edema.

[@jamesfowley4114]

You need x numberc of o2 molecules per breath. Pressure and purity only need to be with the parameters that allow that many o2 molecules into your lungs.

[@ianlaughlin85]

That didn't answer the question of why partial pressure of volume is more important than oxygen percentage. It wouldn't matter what percentage of air is oxygen as long as it's higher than what is the blood. Hemoglobin does not reenter the lungs oxygenated so the gradient will move towards the blood. Your lungs can absorb oxygen at low concentrations. Why is partial pressure important? I don't think it matters. You can breath just fine in 100% oxygen or 22%. You will absorb as much oxygen as your hemoglobin can hold. At hight altitude you body will produce more red blood cells to grab more oxygen.

[@oriongaby]

@@ianlaughlin85 percentage of O2 is meaningless if you dont also know atmospheric pressure and temperature. Lets say we have a gas mixture of 22% O2 (and lets assume temperature is constant), because the total pressure of a gas mixture is the sum of the partial pressures of its components then the partial pressure of O2 at sea level is 0.22*760mmHg = 167.2mmHg, while the same mixture of 22% O2 at the top of mount Everest (atm. pressure of 235mmHg according to google) is 0.22*235mmHg = 51.7mmHg. A quick google search says normal p.p. of O2 in blood plasma is between 75-100mmHg, if the p.p in blood plasma is higher than the p.p in air then the O2 cannot diffuse into the blood plasma. (In reality numbers will be different since i ignored temp to simplify things) Oxygen needs to diffuse through the respiratory membrane into the blood plasma before Hemoglobin can bind to it, so Hgb is outside the scope of the question.

[@lepetitmonster8737]

@@ianlaughlin85 for the oxygen to cross the alveolar membrane, the alveoli has to have a higher partial pressure of oxygen than the venous blood on the other side of the membrane. Gasses follow the rule of gradient dissociation, so oxygen will go from the place with higher oxygen partial pressure to the one with lower oxygen partial pressure. In the test known as Arterial Gasometry, there’s a value known as A-a O2 gradient, which calculates the ability of oxygen to diffuse from the alveoli to the blood. Also there’s a bare minimum amount of atmospheric gas pressure for air to get inside your lungs and your alveoli to not collapse. Respiration happens thanks to the pleural cavity having a negative pressure compared to the atmospheric pressure, so when the diafragma contracts and lowers, air comes in and expand the lungs thanks to that negative pressure and the alveoli’s elasticity. The amount of oxygen is pointless if your lungs collapse onto itself. Hope it helps! English is not my first language, so tell me if something sounds weird!

[@s.spencer7917]

Partial pressure of O2 is important because absorption of oxygen in the lungs and cells is driven by diffusion, which is the passive movement of molecules across a membrane from areas of higher concentration to lower. The partial pressure of O2 is what creates the concentration gradient which "pushes" O2, via diffusion,into the avoili, from the alvioli into the blood, and from the blood into the cells. Cellular respiration in the mitochondria is an oxydation/reduction reaction, dependent on oxygen to absorb the electrons from the election transport chain, and the oxygen is reduced to H2O. The O2 has been "used" and now needs to be replaced. Luckily for living things, the oxygen that is now in the water molecules no longer contributes to the partial pressure of O2, so the pressure of O2 in the intracellular matrix is now less than The concentration outside the cell. We now have a convention gradient across the cellular membrane, which will drive diffusion of O2 into the cell. There is some tolerance for changes in partial pressure of O2, e g. a decrease amount of O2 available for cellular respiration, however in order to maintain cellular respiration, there needs to be a certain amount (mass) of O2 moving into the body over a given time period. Let's say that atosoheric pressure is maintained, however we remove half the O2 and replace it with nitrogen. While the overall pressure has not changed, the concentration of oxygen in the air has been cut in half. This means that, since absorption of O2 into the body depends on the concentration of O2 in the air, that's half as much oxygen that is "pushing" it's way into the tissues, e.g. half as much oxygen that is available to use in cellular respiration. As you might imagine, this would quickly become problematic. In the opposite scenario, where all other gases are removed from the atmosphere, but the partial pressure of 02 remains the same, there would be a massive drop in overall pressure. However, since the amount of O2 that is being "pushed" into the tissue is the same as normal, cellular respiration would continue as normal. Oversimplified: it is a question of raw numbers vs percentage. Even if the percentage of O2 in the air reminds the same, if the pressure drops, there's not enough raw numbers of O2 to support cellular respiration. If the over all pressure drops, but the number of O2 molecules remains the same, i.e. the partial pressure does not change, the number of O2 molecules to drive cellular respiration remains the same.

This would be an excellent opportunity to experiment with space junk capture and removal techniques. The low orbit would ensure that a mess isn't left behind for long if the junk capture process is only partially successful. There are several companies developing deorbit vehicles. In the short term those are only being used on intact satellites and rocket stages. There are proposals for space junk encapsulation technology for stuff that is likely to fall apart.

On the partial pressure vs. percentage question, you're partly right, in that it takes a certain pressure to get oxygen into the cells, but more importantly (and pulling from the preceding chemistry joke), you need a certain number of moles of oxygen per unit time, so the lower the overall pressure, the more of that pressure needs to be oxygen.

Explanation for the feasibility of Snow Piercer...There is no explanation, it's a dumb concept.

[@AndrewJohnson-oy8oj]

It's an allegory. You're not supposed to take it literally.

[@johnjapuntich3306]

@@AndrewJohnson-oy8oj Allegorical sci-fi is fine as long as it's good sci-fi. For sci-fi, no matter the sub- genre, the premise is important and for this movie and series, it's a total fail.

Thoughty2 puts SO much unverified / unproven claims in his videos with 0 context and it cimes across as facts. I can't watch his channel anymore.

[@thatsgoodsports]

One of those “It Finally Happened” videos was actually really good

[@dropnoelfield295]

Love your stuff, mate. Thanks

LOL "seating" low earth orbit. Best pun not caught

[@bassface876]

Yeah on the snowpiercer track maintenance thing, my bands singer is a railroad worker and we totally have to be very careful about scheduling winter shows because he will be called in to help keep the tracks clean if snow is even remotely in the forecast. so yeah the whole tracks and constant snow thing doesnt...track...

[@navydvr1215]

As a Navy Diver, I would 100% buy a “Pressure Changes Everything” shirt. That’s the best idea ever! Also Partial Pressure has more to do with the actual amount of molecules of a gas in the same volume, so you’re not far off. Say when we dive to 250 feet of sea water, we will breath 10% oxygen 90% helium, because that 10% oxygen will have more oxygen particles in it then the 21% oxygen on the surface because it is so compressed by the pressure. If we were to breathe 21% oxygen at that depth it would have the equivalent oxygen molecules as if you were breathing 180% oxygen on the surface which is actually toxic to the human body.

[@AaronWood]

Missed the opportunity for a "It's starting to.... crap out." ;)

[@CarolinaCustomKits]

Higher pressure increases density, allowing more molecules per volume. That fact can help explain it.

[@zapfanzapfan]

From my understanding, the bacteria virulence on ISS is because zero gravity is more similar to the conditions inside of our bodies (which they have evolved to) as opposed to the bacteria being on a surface in a petri dish. So, experiments in zero gravity should actually yield more accurate results. Maybe testing procedures down here can be improved?

[@PreppingWithSarge]

Boeing sends a rocket up to Space Station. Space Station bathroom breaks. Coincidence? You decide.

[@Bacopa68]

Partial pressure is more about gas diffusion from air sacs to the blood rather than getting it into the lungs themselves.

[@ericsecrist4084]

The pressure thing sounded good. I'm going with it

[@s.patrickmarino7289]

I was at a conference about a year ago where a NASA biology researcher gave a talk on the subject. The fun aspect was, the bacteria they grew in space tended to get physically larger due to tecnobabbly gravity does not squish it and stuff. The bacteria because it was larger was better able to collect food. It had more surface exposed. When they brought the space bugs back, new generations continued to be big, even without significant genetic changes. The fun thing is, everyone expected the smaller bacteria to out compete the big blobs in a 1G environment. That's not how it worked. When they mixed them up in the same dish, the space bugs dominated their stay at home brothers and sisters.

[@ericl447]

Too busy lately. Forgot how good this guy is, love him. ☺

[@clintono]

My thought of the bacteria in space is that because it is an isolated environment bacteria would tend to collect rather than being spread by wind etc. so higher concentration = higher infection rates.

Don't forget the thumbnails with that dreaded yellow or red arrow pointing at something

You realize that Atlas Shrugged is also a post apocalyptic train survival book/film(s).

Thanks for the suggestion to watch Beato - my bf watches him a lot. I'll check it out.

[@mattiemathis9549]

Talking about the problems with the space station brings up something I’ve never really thought about concerning the “living in space” concept. A traditional home can last hundreds of years with proper maintenance, that’s several lifetimes. A person can feel good that, although expensive, it will be there for generations. I find it difficult to believe that ISS isn’t getting maintenance, so do things deteriorate faster up there? It would make sense. We have to use lighter materials and radiation and such. How does that affect the concept of “a city in space”? Would they have to shut down areas for repairs endlessly? Or is the deterioration so bad the whole thing has to be scrapped? The general idea of a home is it will generally appreciate in value. It seems like space stations would start depreciating value as soon as they are launched. Down another rabbit hole I go! 😂 Thanks for keeping my brain sharp!

[@JimSuperwhite43]

You mention your algorithms. My algorithms tend to get it a rut, which leads me to think that wouldn't it be cool to have a platform that offered various super genius algorithms that you could plug into your own feed? Or just a ten video list that you could plug in to your present feed to disrupt the repetitive offerings? Kind of a curated algorithm.

[@daretodreamtofly3288]

2 things to think about with the train. How often is it being used? Is there some type of maintainer apart of snow piercer? Or perhaps one that is leading the way? If it's the only train then the metal track should last quite some time as they could be built out of more rust resistive materials as no expense would be spared to save the last life on earth. If there's a few different trains that maintenance would become all the more difficult in short order unless there was trains bespoke to the the task of clearing the track and replacing rails. I mean look at the standard age of the tracks in the US and Eu. Though much of it gets replacing every so often the lines are typically 100% new. The real question is for how long would they need to do this. Still I'd figure something along the equator should always be better than a train.

[@ironmaiden795]

On the AI music, I watched that and used the website he mentioned to experiment. I've been a musician for 15 years and around half were close enough to not be able to tell, others had something wrong that sounded mechanical in some way. One of my friends, who isn't a musician, he said the same as Rick's kids that it was "obviously AI", so I'm not sure if it's generational, I think some people can hear it and some can't for some reason. Weird, interesting, probably a deep dive waiting to happen

[@OlyChickenGuy]

I actually subscribed to you and Thoughty2 around the same time. Neat to think someone I enjoy watching and look up to could very well be watching a video with me at the same time(ish). I'll certainly be thinking of you as I watch Thoughty2's channel from here on out. :3

12:21 - Pressure, or the lack thereof, is why trying to hold your breath if you were exposed to a vacuum would be a very bad idea. Your saliva and tears will still boil away, and you'll have a severe case of the bends, but you might survive a few more seconds to get rescued if you don't rupture your lungs. Oh, and if it's the vacuum of space, you'll get radiation burns from all the cosmic rays and solar particles that Earth's magnetic field protects us from.

[@rustkitty]

The original Snowpiercer graphic novel featured some thermodynamics-violating science-fantasy engine that generated power from motion. So as long as the train runs they generate a surplus energy that they can use for heating. I don't think the writer cared about the tech, it was just an excuse for social commentary. By the way Snowpiercer isn't the only player in the train apocalypse subgenre. There are a bunch of zombie stories (like the steampunk anime Kabaneri of the Iron Fortress, the Korean movie Train to Busan, the side scrolling action game The Final Station) where trains are used as moving HQs. That's easier to stomach because the main concern with zombies is being overrun and a moving train solves that.

[@alanfike]

Sound results from _changes_ in air _pressure._ Pressure changes everything.

[@yellstr]

I think at some point in the show they said that Snowpiercer's engine somehow steals a bit of Earth's angular momentum
