Note on Hypoxic Diluents
Hypoxic diluents such as 10/50 in this
example require special training since they
can be deadly near the surface�
5. Pre-Dive
- Prior to beginning the dive we can see
from the mode indicator that we are in CC mode� Our
active diluent gas is set to 10/50, our set point is 0�7,
and the Perdix 2’s battery is sufficiently charged�
6. Diluent Check
- Pressing the right button a few
times brings up the diluent PPO2� The red indicates
the diluent is unsafe to breath directly�
This information can be viewed at any time to verify
the diluent is safe or to check what the expected
PPO2 will be when flushing with diluent at depth�
7. Automatic Set point Switch
- The optional auto
set point switch was enabled with a depth setting
of 15m� So as we descend past 15m, the set point
automatically switches from 0�7 to 1�3�
8. Decreasing NDL
- As we descend deeper, the NDL
decreases� The TTS shows it will take 5 minutes to
ascend to the surface at 10m/min (33ft/min)�
9. Bottom Time - We have completed the bottom
time� The TTS indicates we have about 1�5 hours of
decompression to do� The first stop will be at 48m for
1 minute� We have GF99 set to replace NDL while we
have a decompression obligation�
10. Ascending to the First Stop
- Here we are
ascending at 3m/min� This is slower than the
expected 10m/min ascent rate� This slow ascent has
caused the TTS to rise, as most tissues are still on-
gassing�
