1 Diving at Reduced Risk with Aladin

1.4 Response in increased risk situations
If the dive includes an increased risk situation, Aladin
®
Pro Ultra reacts automatically to warn the diver of
this risk and increase required decompression, as the case may be. A change of decompression may be
indicated to minimize the risk. The diver can further reduce the risk by following conservative diving prac-
tices on the next dive and at the same time prevent long decompression stops.
A few examples are on the following pages:
Situation 1:
The diver ascends too rapidly:
Reaction of computer:
The model calculates the formation of bubbles due to the excessively rapid
ascent. The no-stop time is shortened or a longer (and eventually at greater
depth) decompression prescription is displayed in order to assure increased
decompression. See pages 37, 42 and 43.
Recommended response of the diver:
During the dive:
Observe the new decompression prescription shown by Aladin
®
Pro Ultra.
After the dive:
• Watch for symptoms of arterial gas embolism and decompression sickness.
• Seek immediate medical attention at a recompression chamber should any
signs or symptoms of decompression sickness appear.
• Before the next dive, plan a sufficiently long interval (display <Atn> should have
disappeared).
An exessive ascent rate can lead to serious injury or death from decompressi-
on sickness. Failure to seek IMMEDIATE treatment for any signs or symptoms
of decompression sickness after a dive may result in serious injury or death.
