injury or death from decompression sickness.
For the calculations of the desaturation and No Fly Time it is assumed that the
diver inhales air.
5.4 Warning of bubbles
Through repetitive dives microbubbles accumulate in the lungs if the surface
interval is not long enough. Ignoring decompression stops or an excessive
ascent rate can also lead to bubbles in tissues. In order to reduce the risk of
decompression sickness for future repetitive dives, the surface interval should
be planned long enough to reduce the risk of decompression sickness. If
Aladin
® Air Z O

calculates that the formation of microbubbles occur during the
surface interval, it will advise a diver to extend the surface interval. If the dis-
play <Atn> (=attention) is visible instead of the depth during the surface inter-
val (surface-mode), the diver should not undertake another dive. Through the
extension of the interval the diver may prevent a high concentration of bubbles
in the lungs during the planned dive and avoid a higher risk situation. See also
page 78.
– If the dive has to be made during <Atn>-time, the <Atn> time of the following
dive can increase considerably.
– If the dive is made in spite of the display <Atn>, the diver must cope with a
significantly shorter no-stop time and an extension of decompression time.
