At most, an astronaut without a suit wouldlast about 15 seconds before losing conciousness from lack of oxygen. (That's how long it would take the body to use up the oxygen left in the blood.) Of course, on Earth, you could hold your breath for several minutes without passing out.

I'm going to answer this completely differently than anyone has ever done in the past, because I think everyone who has answered it before was wrong, including top NASA scientists.

First off your body does not need an atmosphere. You only need one around your ears eyes mouth and nose; and you can do without around your eyes and nose in a pinch. What the rest of your body needs is counter pressure, this can be provided with something as simple as fabric. I’m not going to worry about that for now because even in a vacuum you would puff up a bit, your capillaries would expand but for the short term you’ll be fine. Except for the aforementioned ears eyes nose and mouth.

Barotrauma is damage to the body caused by a difference in pressure. You can start getting damage to your lungs at just 2 psi over pressure but are not likely to get immediately life threatening damage unless its significantly higher than this, around 12 psi over pressure.

The space station is pressurized to around 14.7 psi, if it had an explosive decompression you should let out most of the air from your lungs bug hold in some. If you let it all out your lungs will actually start working backwards pumping air out of your system into the vacuum and cause you to pass out almost instantly. With partial air held in your looking at maybe a minute and a half of consciousness to save your self. Uese that time to get in a new compartment, slam the hatch shut and trying to repressurize it.

In a space suit things are actually better. Space suits run at only around 2.5 to 6 psi and have almost pure oxygen. Space debris blows a hole in your visor, HOLD YOUR BREATH! The barotramatic injury is far more manageable than certain death from exhaling to prevent lung damage. If you’r in peak condition you have maybe three life saving minutes to your problem resolved or get back in the air lock. Just be aware the water on your eyes will start to boil, so don’t expect to be able to see for long.

I think they should have on hand in any space environment tight fitting face masks that can provide 2 psi of pure dry oxygen for 15 minutes of breathing. On mars or on orbit if there is an emergency you could grab one of them off the wall and evacuate to a pressurized area.
