Reducing the risk of Taravana
m WARNING!
This manual is not a scientific text and is no replacement for adequate training!
Taravana (“madness” in Polynesian) is a syndrome with symptoms comparable to severe decompression sickness in scuba diving and
include trouble with speech and walking around, and in the most severe cases, convulsion problems through to possible coma.
Hyperbaric medicine it not unanimous in identifying the causes that trigger the syndrome. Nevertheless, the recognized factors that
increase the risk of Taravana are:
• Lengthy stays at very deep levels with repeated dives over time (2-4 hour sessions).
• Exposure to deep levels without adequate recovery time on the surface.
• Hypoxia(Insufcientoxygeninthebody).
• Dehydration.
Taking into consideration all the possible causes that can trigger the syndrome, after every dive JACK suggests the minimum “Recovery
time” (RECOVERY) before beginning the next dive to reduce the risk of Taravana.
The variables can be set from the FREE SET menu in JACK (see dedicated section in this manual).

After every dive, JACK shows the minimum recommended recovery
time (RECOVERY in small text). If the minimum recovery time has not
yet elapsed, the SURF TIME information is highlighted in BLACK.
When the surface time surpasses the minimum
recommended recovery time, the Surf Time
value is shown against a neutral background.
