There's something called BOLD imaging, which is Blood Oxygen Level Dependent imaging.

There's only one third as much oxygen at the summit as there is at sea level.

The first limitation is the oxygen oxygen toxicity.

And currently we're working on oxygen oxygen delivery on site.

Liquid oxygen

Water consists of hydrogen and oxygen.

The primary purpose of the gas system is to provide oxygen, to replenish the oxygen that your body consumes.

Love is like oxygen.

We had lost seven tons of oxygen.

Because of the movement I was wasting oxygen.

Water is made up of oxygen and hydrogen.

Oxygen and hydrogen make water.

Photosynthesis is modulated by oxygen, and we have an oxygen insensitive hydrogenase that we think will totally change this process.

It's called a carbon oxygen dwarf.

She tripped over her oxygen tank.

We're all breathing air right now. Air is a mixture of oxygen and nitrogen, about 20 percent oxygen. About 80 percent nitrogen is in our lungs.

So, in this room, there's 20 percent oxygen or so, and if we reduce the oxygen concentration, we will all be dead.

And because you can't bind the oxygen, maybe you wouldn't consume it, and then maybe it would reduce your demand for oxygen.

It inhales oxygen, just like we do.

Stromatolites were the first to exhale oxygen.

It grew as light and oxygen increased.

Its oxygen consumption rate fell by tenfold.

I have an oxygen hose connected here.

The oxygen tanks didn't quite work right.

But in this case, we measured the different isotopes of oxygen.

The most critical part of a rebreather is the oxygen sensors.

We're flying through 2,000 lattice of atoms oxygen, hydrogen and zinc.

You get a hypoxia, or a lower oxygen.

Oxygen, hydrogen and zinc have their own signature.

I was so fascinated by that Oxygen commercial.

It's not hard it's just three oxygen atoms.

There's a built in oxygen concentrator down there.

The technology for oxygen delivery is not new.

Trees give off oxygen and absorb carbon dioxide.

When it came to our atmosphere, however, it wasn't that much of a joke over the long term, because it turned out that we were losing oxygen, quite a lot of oxygen.

It happens because there's too much concentration of oxygen in your body.

Most of the oxygen in the atmosphere is generated by the sea.

In fact, that one is a carbon oxygen dwarf.

He had an oxygen toxicity seizure and he drowned.

In this case, you're seeing oxygen bubbles come out.

We're actually measuring its oxygen consumption, its energy consumption.

We put water over its gills, give it oxygen.
