It's made with ventilation thru hidden inlets (often hundreds of meters away), the outlets are over pressure protected, when a explosion outside goes off those then close, so the inhabitants have no eardrum rapture, in the case of nuclear/chemical/bio attack you attach big filters to the inlets. In some Bunkers the circulation is so bad, that after 2 week sleeping on your mattress mold starts to grow in it (bunkerhusten (bunkercough) is common after 1-3 weeks because of that mold), natural fortresses/bunkers drip water quite allot from the ceiling, but sleeping and living "rooms" are normally plastered or with concrete walls.

Maybe a stupid question, I understand that with Swiss Conscription this is perhaps common knowledge for a large chunk of the Swiss population. Nevertheless is this really public knowledge? As in, should you really be disclosing how bunker ventilation operates, and the additional protection mechanisms etc.?
>should you really be disclosing how bunker ventilation operates, and the additional protection mechanisms etc.
No problem, even civil bunkers works like that, you can make tours and even buy some. However there are some bunkers which are used as "control-centers" and those locations are kind of ~secret, but then again i'm really sure that Russia and the US already know much more about them as i do.
That's a typical over-pressure vent (seen from the inside):
Hint for recruits/active military: In military bunkers the outlets are also very important so that the "enemy" cannot smell your kitchen or see the warm air (infrared), which makes it a excellent place to smoke some green stuff ;)
As someone with a causal passing interest in the cold war and nuclear weapons, yes this is public knowledge. How to build a blast shelter or fallout shelter was widely disseminated in the cold war for citizens to build their own. Overpressure protection and NBC air filtration is just part of building a good shelter. The filtration systems are not some exotic radiation neutralizing material, they are just filters to catch irradiated particles and keep them from entering the shelter and being breathed in. If anything, the pictures of the bunkers showing their camouflage design and locations would be the biggest disclosure, but even that is obviously not an issue at this point.
