Higher Risk Dive Profiles
The user must understand that all decompression
devices (decompression tables and/or dive com-
puters) are based on mathematical models and
that many experts are currently concerned that
these models may not under certain conditions
adequately describe the physiological phenom-
ena. These conditions are presently identified as
dives which incorporate the following:
·
REVERSE PROFILES where the diver
spends most of the dive at shallow depths
and then descends to the maximum depth
shortly before surfacing.
·
SAWTOOTH PROFILES where the diver
alternates between greater and shallower
depths repeatedly throughout the dive.
·
CONSECUTIVE DIVES where the diver
performs repetitive dives to approximately
the same maximum depth with only short
surface intervals between dives. The risk of
decompression sickness increases when
depth and the number of repetitive dives in-
crease and when the surface intervals are
shortened.
