▁ 2   ft ▁every ▁two ▁hours ▁from ▁ 2 0   f sw ▁to ▁ 4   f sw . ▁ ▁St aged ▁decom pression ▁▁ ▁De com pression ▁which ▁follows ▁the ▁procedure ▁of ▁relatively ▁fast ▁as cent ▁interrupted ▁by ▁periods ▁at ▁constant ▁depth ▁is ▁known ▁as ▁st aged ▁decom pression . ▁The ▁as cent ▁rate ▁and ▁the ▁depth ▁and ▁duration ▁of ▁the ▁stops ▁are ▁integral ▁parts ▁of ▁the ▁decom pression ▁process . ▁The ▁advantage ▁of ▁st aged ▁decom pression ▁is ▁that ▁it ▁is ▁far ▁easier ▁to ▁monitor ▁and ▁control ▁than ▁continuous ▁decom pression . ▁ ▁De com pression ▁stops ▁ ▁A ▁decom pression ▁stop ▁is ▁the ▁period ▁a ▁diver ▁must ▁spend ▁at ▁a ▁relatively ▁shall ow ▁constant ▁depth ▁during ▁as cent ▁after ▁a ▁d ive ▁to ▁safely ▁eliminate ▁absor bed ▁in ert ▁g ases ▁from ▁the ▁body ▁t issues ▁to ▁avoid ▁decom pression ▁sick ness . ▁The ▁practice ▁of ▁making ▁decom pression ▁stops ▁is ▁called ▁st aged ▁decom pression , ▁as ▁opposed ▁to ▁continuous ▁decom pression . ▁ ▁The ▁diver ▁ident ifies ▁the ▁requirement ▁for ▁decom pression ▁stops , ▁and ▁if ▁they ▁are ▁needed , ▁the ▁depth s ▁and ▁dur ations ▁of ▁the ▁stops , ▁by ▁using ▁decom pression ▁tables , ▁software ▁planning ▁tools ▁or ▁a ▁d ive ▁computer . ▁ ▁The ▁as cent ▁is ▁made ▁at ▁the ▁recommended ▁rate ▁until ▁the ▁diver ▁reaches ▁the ▁depth ▁of ▁the ▁first ▁stop . ▁The ▁diver ▁then ▁maintain s ▁the ▁specified ▁stop ▁depth ▁for ▁the ▁specified ▁period , ▁before ▁asc ending ▁to ▁the ▁next
