Not very long: The brain is extremely sensitive to anoxia (being without oxygen). Depending on other medical issues, after approx 5 minutes brain damage can occur, which is why it is so important to begin CPR immediately.

Possibly: Any time your heart stops pumping, the blood in your arteries and veins stops flowing. Therefore all of the organs are not getting the blood they need to function. The brain is a very sensitive organ and can get damaged if it is not receiving proper blood flow. There are ways to check the brain for such damage. Talk to your doctor about seeing a neurologist.

2-4 minutes: It depends on age, temperature, cause of cardiac arrest, whether or not CPR is done and other factors but 2-4 minutes is about it.
