In all reality there is no such thing.
All dive tables set maximum ascent rates for divers which is actually a decompression procedure.
As you recall from your entry-level scuba course, as divers expose themselves to the increased pressures of depth, inert gases such as nitrogen and helium are absorbed into the tissues and blood. No-stop divers make realitively short stays at depth in order to reduce the amount of inert gas absorbed into the body. Becuase stage-decompression divers do not have the option of making a direct ascent to the surface in an emergency they must apply special procedures and equipment to reduce their risk exposure. Protecting their breathing gas supply is obviously a priority. Typically stage-decompression divers will dive with two tanks, coupled together via a special manifold with an isolation valve between the two tanks.
