3.2.4.2.  PERSONAL ADJUSTMENT
There are adverse personal factors for DCI which divers can predict in advance 
and input into the decompression model. Factors that may affect susceptibility to 
decompression illness vary between divers and also for the same diver from one 
day to another. The three-step Personal Adjustment Mode is available, if a more 
conservative 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]
• 
the diver is below average physical fi tness level
• diver 
fatigue
• diver 
dehydration
• 
previous history of DCI
• stress
• obesity
The Personal Adjustment Mode is indicated by a diver symbol and plus signs (P0 
= a diver, P1 = diver +, or P2 = diver ++). Chapter 4.6. describes how the Personal 
Mode is adjusted.
