Wandering if there is another reason besides terrain to maintain FL 180/7min
FL140/30 min. For 13 min oxy sys.
Is someone telling you to stop your descent prior to the MEA and/or 10,000 feet?
Is it recommended (terrain permitting) to descend straight to FL100?
If you have a rapid decompression, almost always (I'd stop for traffic if I absolutely had to, but just until it's no longer a factor).
Someone suggested its recommended to fly the profile to let the body adjust.
Adjust to what? A significantly higher altitude than you're leveling off at? "The body" just got a surprise ride to 30+k feet from between 4k to 6k, since you want it to be at no more than 10k, why would helping it "adjust" to 180 or 140 be desirable?
While there is a possibility of decompression sickness for any altitude change, the possibilities of it occurring from an RD are extremely low. It's a lot more common in underwater activity, where 33 feet of water come down on you with a pressure of the entire atmosphere above water (in laymans terms, the body of someone diving who goes from about 30 feet to about 10 feet is rough;y equivalent to an RD).
