NOTE
Section 5.9.4. Setting the personal/altitude adjustments describes
how the Altitude value is set.
WARNING
Traveling to a higher elevation can temporarily cause a change in the
equilibrium of dissolved nitrogen in the body. It is recommended that
you acclimatize to the new altitude by waiting at least three hours
before diving.
5.10.5. 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
•
dehydration
•
previous history of DCI
•
stress
•
obesity
•
patent foramen ovale (PFO)
•
exercise on or after dive
This feature isused to adjustthe computer to bemore conservative, according topersonal
preference, by entering the suitable PersonalAdjustment setting with the help of Table 5.5,
Personal Adjustment settings. Inideal conditions, retain the default setting, P0.If conditions
are more difficult, or any of the factors which tend to increase the possibility of DCI exist,
select P1, or even the most conservative P2. For very experienced divers willing to take
high personal risks and full responsibility of their own condition, two negative values of
the personal adjustments, P-2 and P-1, exist.The dive computer then adjusts its mathem-
atical model according to the entered Personal Adjustment setting, giving shorter no-de-
compression times.
