Back when people were trying to help miners suffering from caisson disease, the idea that excess nitrogen was the cause was born, and people advocated for a slow, continuous ascent. In his studies, John Haldane specifically compared a slow continuous ascent with a staged ascent, and those studies indicated that the staged ascent was better. That eventually became the norm.
With a database of a few million real-life deco profiles, we could run them through the ascents with different increments and see if there is a trend. Or perhaps several clusters depending on max depth, or gas, and so on.
@Duke Dive Medicine (or anyone else that knows), we're taught that one of major reasons to take air breaks during lengthy O2 stops is to reduce mucus buildup (improving subsequent gas exchange). Does partial pressure drive that buildup or is it more tied to the fraction of O2 breathed?
@Duke Dive Medicine: could two staged decompression dives per day at a depth of 165 ft per dive over ten to fourteen subsequent days resulting in high CNS toxicity as a consequence. Would those types of dives prevent you from using a hyperbaric chamber if you were to get bent?
