HIGHER RISK DIVE PROFILES

The user must understand that all decompression devices (decompression tables and/or dive computers) are based on

mathematical models and that many experts are currently concerned that these models may not under certain conditions

adequately describe the physiological phenomena. These conditions are presently identified as dives which incorporate the

following (Fig. 1.1):

• SAWTOOTH PROFILES

where the diver alternates between greater and shallower depths repeatedly

throughout the dive.

• REVERSE PROFILES

where the diver spends most of the dive at shallow depths and then descends to the

maximum depth shortly before surfacing.

• 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 increase and

when the surface intervals are decreased.

• MULTIDAY DIVES

repetitive dives performed for several consecutive days.

• DECOMPRESSION DIVES

any dive during which the no-decompression limit has been exceeded or the diver

is advised by the computer that he may not return directly to the surface.
