You really should come up slowly from the oxygen protion of the deco. For long exposures below 20 feet , you actualy have to so a little deco to get off of it, or you get the expanded oxygen bubbles , just like the other gases do, and it hurts like hell. However, it goes away quickly. The recommended rate is one foot per minute, and we generally ascend a foot a time from 20 to see if it is going to hurt. I usually do between 5 minutes and the full 20 to get out of a long one.
