SSI ENRICHED AIR NITROX EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+ 2025 - 2026
What is the best, safest, and most comfortable way to track your
oxygen and nitrogen exposure at the same time?
Use a nitrox-programmable dive computer
According to the SSI CNS Clock table you have two different CNS
Clock limits. One for a single dive, and one for a 24 hr period. These
limits are for an ppO2 of 1.4 bar:
150 mins single dive / 180 mins 24 hrs
Which of the following is a significant difference between planning
a dive on nitrox and planning a dive using air?
You must also manage your exposure to oxygen
On each dive you determine the percentage of the CNS "clock" limit
that you received. When making multiple dives you have to:
Add the percentages together and avoid exceeding 100%
What are the two most commonly used Nitrox mixtures?
EAN32 and EAN36
, What is an advantage of using Enhanced Air Nitrox?
longer no-decompression limits, shorter surface intervals and longer
repetitive dives
What is a limitation of diving with EANx?
Nitrox requires additional training in order to use safely
Compared to air, nitrox has a higher concentration of:
oxygen
Is it true, that nitrox is designed for ultra-deep diving?
No, nitrox has more restrictive depth limitations than air
A common misconception is, that compared to air, Nitrox enables
Divers to dive:
deeper
While diving nitrox, you can improve your safety by:
Using the no-decompression limits of an air computer or air tables
The air that we breathe is approximately:
79% nitrogen and 21% oxygen
EAN32 and EAN36 are commonly referred to as
Nitrox 1 and Nitrox 2
Diving nitrox exposes your body to more _______
oxygen
What Does ppO2 Mean?
partial pressure oxygen
What is the range of ppO2 levels that can sustain life
