lit up, 100% of the maximum tolerance allowa-
ble to the CNS has occurred and serious danger
of hyperoxia exists.
It is important to understand, monitor, and con-
trol the oxygen toxicity level. In order to reduce
the risk of oxygen toxicity, Leonardo displays a
graphic bar, easy to read in any situation. When
the oxygen level reaches warning values, next to
the maximum allowable toxicity (corresponding
to 5 segments out of 5 lit up), the graph starts
flashing along with the Nitrox writing, and a tem-
porary alarm starts sounding, showing the pro-
ximity of a CNS toxicity level. If the situation
remains unchanged or worsens (100% of allo-
wable toxicity), the bar and the writing continue
to flash and the temporary sound alarm is re-
peated until, ascending, the partial oxygen pres-
sure decreases below 0.6 atmospheres. The
graph stops flashing, yet the alarm is entered in
the Logbook.
NOTE: The result of the oxygen exposure
computation is approximated to the nea-
rest whole number.
DANGER: do not use hyper-oxyge-
nated mixtures in diving or decom-
pression without having attended the
related training courses. The Nitrox
Basic license enables to use just the
standard hyper-oxygenated mixtures
(Ean 32 and Ean 36, respectively called
Nitrox 1 and Nitrox 2), within the non
decompression limits.
