General Nitrox Dive Parameters
Oxygen Partial Pressure
When the diver reaches a depth at which the PPO2
exceeds the maximum limit entered in the corresponding
parameter, (from 1.2 to 1.6 ATM), Nemo triggers an
alarm condition signaled by:
• blinking depth indication;
• audible alarm.
The alarm persists until the diver has ascended enough
for the PPO
2 to return within the programmed limit.
Effects on Central Nervous
System
Oxygen toxicity exposure is monitored by means of a
CNS (Central Nervous System), based on currently
accepted recommendations for exposure limits. This
toxicity is expressed as a percentage value which ranges
from 0% to 100%. The percentage CNS value is shown
on the display. An alarm is triggered when it exceeds
75%, signaled by blinking of the value.
WARNING
When the max PPO2 alarm occurs,
ascend immediately until the alarm
condition ceases.

Note:
The maximum depth shown is an
approximate value which depends on
the salt/fresh water setting,
temperature, altitude, etc.
During the dive the correct Max depth
will be determined on the basis of the
PPO
2 effectively accumulated in the
tissues.
