Controlled Ascent and Safety Stops
"Current philosophy dictates that all dives, even those well within the no-stop limits of tables and computers, should include a controlled ascent (dictated by the diver's computer, tables, or personal or training philosophy) 
and a safety stop. Newly published research recommends slower ascent rates (slower than 60 feet, or 18.2 meters, per minute according to most tables) possibly coupled with multiple safety stops. Reading available data published by the training associations and DAN is a good way to become familiar with the latest information on ascent protocols.
Safety stops provide an opportunity for you to make sure that your equipment is in order and that you slow your ascent before you make the final ascent to the surface - and place yourself in the area in the water column where the pressure change is the greatest. Take advantage of the opportunity."
