Question: Does the breathing get affect when an astronaut is in outer space?

( Back )

Answer #1:

well there is no oxygen in space so yes, they must always have an oxygen supply

Answer #2:

^^^^^

What he said.

Answer #3:

yes. breathing is impossible and continuous pressurised oxygen can solve this problem

Answer #4:

space has vacuum.

There is no gas except plasma and hydrogen

These too are at a very very low pressure (0 psi)
So as u know air moves from high to low pressure..
And You wont be able to create as low pressure as required to suck air into lungs..

Thus altered breathing..

Besides u'l freeze before this cz space temp is close to absolute zero.or -273 centigrade if i remember correctly.

Answer #5:

Is breathing affected when an astronaut is in outer spacee?

There is little gravity in outer space, but this does not affect breathing significantly in a space suit. Apart from probably making it a little easier. If there is no gravitational effect on the circulation, then blood will flow more freely and require less force from the heart to move. This means it will travel more efficiently around the lungs and the body will probably require less effort in breathing.

The fact that space consists of pretty much a perfect vacuum causes breathing outside a space suit to be impossible.

A vacuum is when 'nothing' exists at all, and when a volumne of space consists of pretty much nothing, it's pressure will fall. So space has a very low atmospheric pressure. Materials will move from areas of high pressure to low pressure. Our lungs are used to working at around 1000 mbar of pressure which is relatively high to space, and indeed they need this pressure to operate effectively. High pressure in the body relative to a lower pressure outside, probably going to be painful.

There are no gasses to breathe in space so I'd assume you would suffocate before anything else.

Answer #6:

"since there is no gravity in space" There IS gravity in space, but the astronauts feel weightless due to being in free fall.

Being in weightlessness doesn't affect your breathing. Inside a spaceship, they have normal atmosphere at normal pressure, so they breathe just like we do. Inside a spacesuit, they have less atmospheric pressure, but enough oxygen, so I guess they breathe normally in a spacesuit too.

Answer #7:

Firstly if they are outside any space vehicle they need oxygen supply because there is no oxygen in space and if the person is inside the oxygen need of that person is lower than the amount needed on earth because it takes less energy to do work in space as things are lighter ...
