In brief: Can't survive

If the brain is without oxygen, it will die after about 4 minutes.
If the brain is still alive after 30 minutes, that brain was getting oxygen.

Newborns can have a little more time than that, but not by much. Also, survival is possible if hypoxia and hypothermia happen together - as in cold-water drowning. But even survivors of 30 minute oxygen deprivation are usually significantly brain damaged, with short-term memory, coordination, and executive functions most severely compromised.

Agree with Dr Belilovsky

In brief: Depends

Interestingly enough, if one were to be in freezing temperatures in a lake drowning, brain death may be delayed due to the lowered metabolism due to cold temperatures.
