1 Diving at Reduced Risk with Aladin

Air Z
IV Uwatec ® Aladin ® Air Z
• Never make “square“ dive profiles of 60 feet or greater as repetitive dives.
• Avoid yo-yo diving during repetitive dives.
• Plan for a minimum surface interval of three to four hours.
• Do not attempt repetitive dive if the <Atn> is visible on the display.
• Plan a day without diving once a week.
• Repetitive dives after exchanging the dive computer: Wait at least 24 hour before you start with the
repetitive dive.
1.3 Response in increased risk situations
If the dive includes an increased risk situation, Aladin
®
Air Z reacts automatically to warn the diver of this
risk and to decrease RBT or increase required decompression, as the case may be. A change of decom-
pression may be indicated to minimize the risk. The diver can further reduce the risk through his conser-
vative diving practices on the next dive and at the same time prevent long decompression stops.
A few examples on the following pages:
Situation 1: The diver ascends much too rapidly:
Reaction of computer: The model calculates the formation of bubbles due to the excessively rapid
ascent. No-stop time is shortened or a longer (and eventually at greater depth)
decompression prescription is displayed in order to assure increased decom-
pression.
Recommended action of the diver
During the dive: Observe the new decompression prescription shown by Aladin
®
Air Z.
After the dive: • Watch out for symptoms of arterial gas embolism and decompression sickness.
• Seak 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 dis-
appear).
