How Much Oxygen Does a Person Consume in a Day? 

FYI the diagram at 0:55 is not 19 cubic feet. its 6,859 cubic feet.

19 cubic feet is not a cube with sides of 19 feet. A 19 cubic feet box would has sides of 2' 8".

Okay, you pay to change all the signs, speed meters, radar guns, text books and educate the public, then sure! People seen to forget America is larger, therefore more stuff to physically change in order to adopt a new measurement system.

thank you! I love TED Talks. He was talking about over 10 or 12waist and shoulder high plants per person. Including what oxygen used by cars, I am surprised that people living in cities don't suffocate.

Cubic feet (ft^3) or Cubic Metres (m^3) are just units of volume. If I have a box that was 1 ft x 3 ft x 2 ft, then the total volume would 6 ft^3. So if a box has 19 ft^3 of volume, it could have the dimensions of 1 ft x 1 ft x 19 ft or it could have the dimensions of 2.67 ft x 2.67 ft x 2.67 ft if it was a cube.

Finally! the answers for my science assignment thanks for the video!

Great job man ! Thnx a lot. Can't wait to see the next one ;)

That's funny. He says 19 cubic feet and shows a cube 19 feet on a side. That 's real BrainStuff.

19 cubic feet or 19 feet cubed...very different...very important

Man, love this channel. Is this new?

Haha - you got me, ybbolb. Should I try to use the catchphrase in an upcoming BrainStuff video?

But/gases has no defined volume. So what does the 8 L/min mean exactly?

Here's a good Question. I've heard Casinos in Vegas pump Oxigen in the air to make people less tired. Does this actually work? More O2, less tired. Truth or fiction?

I just find this channel! I love it!

Because only a 12 years old boy would be complaining about other people not using the metric system.

Haha - Thanks, lee sy! I assure you that I'll make as many as my bosses allow. This show has multiple hosts, and I promise you that they're all clever and entertaining. We have SO MUCH stuff on the way. Stay tuned!

Thanks for watching! We have more on the way.

What if we start breathing air having 100% oxygen ? Is it safe ? I am asking this because recently I have seen an oxygen bar opened here in delhi, india. It provides a flavoured pure oxygen for 15mins by charging from 4-7 USD per session.

the TestTube logo is so much more elegant than the rev3 logo

heh i came across your vid on doing research on if hemp plants produce oxygen if so i wonder how much perhaps would be a good candidate for grow on mars as it grows fast and is resilient

thank you that was very helpful

If anyone has done any research on Bioregenerative life support systems (BLSS) (artificial ecosystems consisting of many complex symbiotic relationships among higher plants, animals, and microorganisms), please share links.

Correct me if I'm wrong, but I disagree. I may have taken the stupid math classes but a cube has to have three equal dimensions which would be 19" high by 19" long by 19" wide, or 19^3. So you can't have two sides of different dimensions or it would be a rectangle. But I may be wrong just going off what I learned in school

I had a headache and as I watched the video I thought at the start he said "hey I've been bullied"

my brain has just been incepted, will be thinking about quantity of oxygen the whole day.

Looking forward to your videoes..on the other channels as well. Thank you for actually replying. :-)

appreciate the stats , i would like to know how much oxygen a standard vehicle uses to make carbon monoxide , there should be a sign on every vehicle saying ,"how much breathable air it converts to poison per minute ".

So, 11,000 L of Air and 550 L of Oxygen, let us know what else we are breathing in..? Carbon Dioxide, Nitrogen, Methane, Spiders, skin particles..etc... Love the show and thank you.

Welcome to another BrainStuff #TBT, are you still holding your breath and wondering much oxygen people consume? Find out here.

Nice info...thanks....

Oh and remember, trees and plants breathe CO2 and pump out Oxygen (how convenient).

Liters are not unit that we measure a particles/molecules give the answer in grams/kilograms or mol...

Drop the metric units. This stuff is so brainy and cool I ❤ it

Fun video. :D I liked it. Subbed :P

This is proof that we should stop breathing and become one with the undead stop CO2 production #stopbreathing

A lot of us know and understand the metric system. But living here forces us to stick to the one we have. My job requires that I produce goods with units written in inches because that's the unit the majority use unfortunately. Doesn't seem like there's anything I can do about it.

It'd be awesome if you could add to this a little bit. For example, while we breathe 11,000 liters of air every day, and 550 liters of oxygen, how much of the other 10,450 liters of air do we require? Approximately how much of that is nitrogen, carbon dioxide, ect? What is the minimum amount of "air" a person would need to survive a day? What are the proportions of different gases at different elevations, such as La Rinconada, Peru or Mammoth Lakes, California? :)

"How Much Oxygen Does a Person Consume in a Day? " Not enough because most folks seem to suffer from oxygen starvation that results in stunted brain function.

I am trying to compare what we cosume in air to the amount of Tonnage that a grove of trees will produce approx 120 trees , to produce 5 tons of co2 in a year .

Why can't lavers stop in mid air

Ben Bowlin y u no make more???

Great question, rsingla333! I've seen some (wildly) varying estimates, but I'm going to dig into this over the weekend and get back to you.

So beautiful information

Proving no one's ever been to space

How many licks does it take to get to the center of a Tootsie Roll Tootsie pop?

How much of oxygen intakes per second

Do you think they could invent a device that transmits oxygen straight into the capillaries of the lungs and create a device that compressed ~1000 liters of oxygen, possibly made of carbon nanotubes. You stick it in your mouth and when you breath in you take in oxygen but breath out any unwanted gases. Pretty much like scuba gear but without all the heavy gear. But now that I think about it that gas would weigh a lot. Not sure quite how it'd work.

can you make a comparison to how much water and h2 sharks inhale?

Hey lupic90, I think you'd enjoy "How to grow fresh air," Kamal Meattle's TED Talk from March, 2009. It answers this question in detail, and also lists the specific plants one person needs to completely replenish the fresh air he or she uses during the day. Check it out and let me know what you think!

Sudden manual breathing while watching this.

Aherp derp derp! Derp derp derpity herp derp derp.

What is the cost for 1 L of oxygen

this is good stuff

Thank you

I'm on it. Not 100% sure if I can get away with it, but I promise to give it a try.

lupic90 just watched a BBC DOC. and in part of it they did a thing on how many plants one would need to be able to breath in a in closed environment that measured 30 cubic meters or 1060 cubic feet roughly. They had this guy get into a tank that the oxygen content was significantly lower than what a human needs and that to what early earth was(12% where in as the earths atmosphere now is about 21%) and they said about 300 plants which had 11,000 leaves was enough to raise the room from 12% oxygen to enough to be that of the current oxygen levels on earth the 21% within 48 hours . Not only that but some plants produce more oxygen than others and some have cycles where they use more oxygen at night than they produce in the day yada yada. Also it would depend on a day and night transition or if you have a 24 hour light environment, which means it would depend on if you use the light from the sun or if you produce the light artificially, seeing as part of the plant producing oxygen is the photosynthesis phase in which the plant uses light to turn co2 into o2. Now if that is 100% "spot on" or not I dont know, but its something I have been looking into as well,. I would also expect that it would depend on how much water they were given, how much co2 the person is producing because the plants need co2 (since in this video we only use 5% of the o2 and turn it into co2 so it would depend on how active the person was and how much the plants would need of co2 in order to continue producing o2.) also other factors like how big the person is (bigger person means bigger lungs I would assume along with more oxygen needed.) and the amount of dead leaf matter the plants produce etc. The name of the BBC show was in the How to Grow a Planet. season 1 episode 3 Life from Light. But who knows, I think the best course of action if you are looking at putting yourself in an enclosed environment for an extended ammount of time (Time spent relying on the plants for oxygen would be another factor of course) where the plants produce the oxygen you need, you might want to just double the amount of any number anyone gives you just to be on the safe side lol wouldnt want to become plant food for misjudging lol

Now this is where it gets crazy...

we get addicted junk food which has more oil compared to normal food items.Why don't we get addicted to oil instead? why oily food but not oil.I guess same applies to sugary items.But difference here is that we can still eat sugar but no one would like to drink oil.

What is the deal with oxygen bars?

So how many house plants do I need to sustain myself

Questions. Water is made of Hydrogen & Oxygen right? So, we get Oxygen from the air to live. What about the Oxygen in the water that we drink, where did they go? And what about the Hydrogen? Is 1 litre of water simply a litre of Hydrogen + Oxygen? Or what are the quantities of Oxygen & Hydrogen you can get from 1 litre of water? Btw, thx for the video.

you're the conspiracy voice guy!!

I wonder how many plants it takes to replenish that used oxygen per person.

And someone watching this during COVID.

Oxygen? Not too much since we breath Nitrogen mainly

No reference,,would you please share the scientific references?

You're great.

then comperes and cool it to a liquid and it would only be around .5 letters

Is it just me or am I the only one that started manually breathing while watching this video?

Nice video.

I didn't... I started manually breathing after reading your comment though

nice vid fast and good

Thank u

How much helium are we losing from earth?

5% of air not oxygen.

Then why we use only oxygen in medical treatment, we breath air not just oxygen ? Just a doubt 😄

Nice video but 19 cubic feet? You should be meaning 19^3 cubic feet

so does that mean i can just have 550l of oxygen in a tank and it will last me all day?

So when I locked myself in my 10 foot room for a week, how comes I’m still alive?

I guessed 1000 gallans of air before this video how close was i?

It's pretty easy, you just have to get used to it.

America knows how to use the metric system.

The water that is made is super clean and the recycled urine is very clean too

is the oxygen intake by a beings scales to its size?

yup..you should!! Don't forget the voice too.. :-D

550L x 0.001429 Kg/L = 0.78595Kg / day o2 we inhale

This video is making me breathe manually D:

Will a person survive breathing just oxygen from some container? Like no air in it but just 550l of oxygen.

interesting stuff

So... if there was more oxygen would we breath less?

if we consume so much air how does a scuba diver stay under water for so long ?

Oxygen is air form or liquid form

It was late, I was tired, Now go back to your moms basement

What makes people want to compete

wonderful

Does this mean that astronauts carry with them a tremendous mass of oxygen?

Just think If tree charge us with money one liter 0.5$.....😰😰

KSP PROFILE PICTURE :D

Hey Ben how much water is to much water?( like while drinking the water) Or is it different for each person?

What will happen when The moon gets out off ower orbit?
