3 .10 .1 Ascent rate
The LUNA 2.0 AI employs a variable ideal ascent rate. Its value ranges from 3 to 10m/min (10 to 33ft/min) and the
actual breakdown by depth range is listed in the table below.

If you ascend too quickly, the resulting pressure reduction could lead to microbubble formation. If you ascend too
slowly, the continued exposure to high ambient pressure means you will continue loading some or all of your tissues
with nitrogen.
If the ascent rate is greater than 110% of the ideal value, the SLOW DOWN alarm is shown.
The ascent speed bar in the above screen represents the following:
1 bar -> speed = 20-40%
2 bars -> speed = 40-60%
3 bars -> speed = 60-80%%
4 bars -> speed = 80-100%
5 bars -> speed = 100-110%
6 bars -> speed > 110%
