• The calculation of microbubbles results in altered ascent instructions. If microbubbles are assumed to be
present basedon the data used by the Aladin
®
Air Z, the ascent rate to the surface is reducted to 23
feet/minute. This will help prevent the formation of microbubbles in the arterial circulation and minimi-
zes formation of microbubbles in the venous circulation after the dive.
3.2 Advantages
On the first dives following responsible diving procedures, a diver using the Aladin
®
Air Z should never be
required to decompress, although a 1 to 3 minute safety stop between 10 and 15 feet is recommended
for every dive. If, however, unplanned circumstances arise during the dive which increase the risk of
decompression, the Aladin
®
Air Z can, if closely followed, reduce the risk of decompression sickness by
reducing remaining bottom time and/or increasing decompression time. Some of the more common risk
situations are as follows:
• Repetitive dives, especially those deeper than 60 feet and those with short surface intervals.
• Repetitive dives using square dive profiles.
• Repetitive diving over the course of several successive days.
• Diving in cold water.
• Diving with increased workloads.
• Yo-yo diving (repeated descents and ascents to the surface during a given dive).
• Flying within 24 hours after diving.
• Excessive ascent rate.
If a diver experiences any of these risk factors while diving, the Aladin
®
Air Z will decrease remaining bot-
tom time without requiring decompression, or will add required decompression time in order to help mini-
mize the risk of decompression sickness.
Do not use the Aladin
®
Air Z for planned decompression dives!
If signs or symptoms of decompression sickness occur after diving with Aladin
®
Air Z, seek IMMEDIATE tre-
atment at the nearest recompression facility.
