5.9.5. Personal adjustments
There are personal factors that can affect your susceptibility to DCI, which you can
predict in advance, and input into the decompression model. Such factors vary between
divers and also for the same diver from one day to another. The five-step Personal
Adjustment setting is available if a more conservative or aggressive dive plan is desired.
The personal factors which tend to increase the possibility of DCI include, but are not
limited to:
•
cold exposure —water temperature less than 20 °C/68 °F
below average physical fitness level
•
fatigue
•
70
Altitude range
300–1500 m / 1000–5000 ft
1500–3000 m / 5000–10 000 ft
Section 5.8.2. Setting the personal/altitude adjustments de-
scribes how the Altitude value is set.
Traveling to a higher elevation can temporarily cause a change
in the equilibrium of dissolved nitrogen in the body. It is recom-
mended that you acclimatize to the new altitude by waiting at
least three (3) hours before diving.
