Thats a question of nitrogen saturation in the blood - and that depends on the TIME you have spent on the DEPTH as well as the DEPTH alone .
At say 2-3 meters you could probably stay under for 90 minutes without other precautions than a cold beer waiting in the boat .But as depths increase , the safe -time on the depth decreases and decrompession times increases . (The need to gradually re-surface ) .
You should go to a diving site to check this out too..
