the end of the dive. This drops as your surface interval time
increases.
(4) Nitrogen (N2) exposure bar graph: This is the amount of
residual nitrogen in your body at the end of the dive. This drops
as your surface interval time increases.
WARNING: It is recommended that you wait at least 24-hours
following any dive before flying in an aircraft or driving to
altitude. Failure to allow sufficient surface interval time before
doing so may increase your risk of decompression illness (DCI).
