You may well have read that. But that does not mean it is part of the mandated course.What other specific emergency would they make us manage at 130? OOA and safe ascension seems like the only option?
Otherwise my mistake, thought I read someone else online saying their instructor made them simulate safe ascension with a diver showing DCI symptoms.
Your "simulated emergency" does not have to take place at 130 ft. OOA is far more likely than DCI.
Remember that DCI is either DCS or AGE, and neither happens at depth; they are both caused by pressure release as you ascend.
