it’s usually -40°c outside when you are in cruise altitude. Open your home window when it’s freezing outside (less than 0°c) can give you an idea why you would have fog in the aircraft until its complete decompression.
The mask can produce “oxygen” for about 15 to 20 min max. You have to be below 10000 feets to be “ok” without mask (it will be like being in a montain at high altitude).
Without putting the mask, you loose conciousness in about 30sec.
Note: this scenario is the worse in term of decompression event. Usually this type of failure would happen during the ascent.
Tell me more about this immediate fog thing, what causes it and what doesn’t it clear quickly?
edit: Wait the masks only produce oxygen for 30s or the breathable oxygen at that altitude is only available for ~30s?

If you hold you breathe would you stay conscious longer?
i don’t think its possible (but i’m not an expert on that) due to the sudden differential of pressure you encounter. I assume it’s like being punched.
Best is to react quickly for yourself, then look and help the people around you…
If plane go quickly under 10000 feets, the unconscious people will wake-up (normally)
You would only be awake for 30s after sudden decompression
