Doctor, the patient is desatting.

O2 sat's down 82 percent.

Danger. Atmosphere compromised.

Where have essentially, you have an equal amount and very

So, I would sleep in a hypoxic tent every night.

Oprah gave me four months to prepare and train.

Or you can do it through loss of consciousness, by accelerating in a centrifuge.

The baby was delivered through a C section, but Barbara suffered cerebral anoxia, a loss of oxygen to the brain.

My next step's gotta be oxygen.

What's a drug?

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

Well, I have to tell you something very odd, and that is that being exposed to low oxygen does not always kill.

That's what we use to inject, as we start to do our deep dives.

We need to breathe.

These granules contain three essential plant nutrients.

This was a different record.

So why do extreme G forces and near death experiences produce the effect of seeing tunnels of light?

I've been a miner all my life. You get used to low oxygen.

Get him a nasal cannula and a tank with low oxygen content.

Meanwhile, the human body consists of 65 oxygen, 18 carbon, 10 hydrogen, and 7 of various other elements including 0.002 of silicon.

And he said to me that anything over six minutes you have a serious risk of hypoxic brain damage.

We stopped tilling, so that we could prevent greenhouse gasses from going into the air.

It appeared dead.

High oxygen content.

Oxygen! Yes!

Pure oxygen.

Oxygen, yes. Thermal garments...

What's the O2 stat?

Give me an O2 stat.

Iron and oxygen are elements.

Water contains hydrogen and oxygen.

Liquid hydrogen and oxygen.

Trees give off oxygen and absorb carbon dioxide.

I think I've got hypothermia.

Tropical rainforests produce oxygen and consume carbon dioxide.

And then you have two extra pairs of valence electrons in the oxygen.

Nitrogen bonds to oxygen, which in turn....

And after the toe cells have kind of taken out whatever they need.

I'm H2O intolerant.

You need oxygen to breathe.

And there was no carbon and oxygen in the universe throughout the first generation of stars.

This top light is I'm sorry if I'm making you seasick this top light is actually a water quality display that shifts from red, when the dissolved oxygen is low, to a blue green, when its dissolved oxygen is high.

Oxygen and hydrogen make water.

It's here, the brain.
