…without the bag inflating. So, what is the purpose of the bag?

Any more details?

Oxygen flows from where?

Where the oxygen going to?

Whats the bag attached to?

• Any more details?

Sorry, it is part of the pre-flight information regarding oxygen masks on planes…

Oxygen masks feed a mixture of oxygenated air (through the bag) and cabin air (through a valve).

Then why does it have a bag?

Right hand side of the flow chart under the word “…MASK?”

When the bags drop a lot of people get panicky. They over breathe.

So the bag acts as a breathing properly indicator then.

ok.

Ah, ok.. I visualized an anaesthetic machine.

And a gas mix regulator.

Pure oxygen, or an oxygen rich air mixture (which ever the mask supplies) is not a good thing to have floating around in a confined airframe. As the oxygen is continuously supplied to the mask, it is important to be able to contain any excess pure oxgen which might build up if, say, the wearer holds their breath. This is what the bag is for.

Because oxygen is part of the fuel-ignition-oxygen triangular thingy.

Remember Apollo 1

They who controls the oxygen controls the breathing

Yes Mr Cohaagen.

This makes reasonable sense. Thanks…

Are you on a plane ?

• Are you on a plane ?

Not today, but I have done some flying in the last week which prompted the questions as I heard the statement a number of times and was curious about it…
