Decompression procedures for transfer under pressure (‘TUP’) diving

Absence of experimental testing of the candidate tables precludes firm conclusions regarding differences in P_DCS. All candidate tables are recognised internationally as well as within their national jurisdictions, and final decisions on procedure preference may depend on factors other than estimated P_DCS. USN and DCD procedures would be expected to have lower P_DCS than MT92 and DCIEM procedures, but the magnitude of these differences is not known.
