Not long ago, the hyperbaric facilities of the Belau
(Palua) National Hospital and Chuuk State Hospital were
inspected by Dr. Timujin A. W. Wong, a hyperparibic physician
in Montreal. This is a synopsis of his report, which
originally appeared in the journal of the South Pacific
Underwater Medical Society.
At the modern Palau facility, 46 diving
patients had been treated in a 34-month period
(during the same period, 6 divers died, including
a group of 5 Japanese who were swept out to the
open ocean by strong currents and lost).
During a typical peak-season week in Palau,
about 2,400 dives are logged, which means the
reported incidence of DCS is from 0.1 percent to
0.01 percent, far below the 0.4 percent estimated
by DAN in its American statistics. Eighteen (39
percent) were U.S. citizens. Although more than
50 percent of the divers visiting Palau are either
Japanese or Taiwanese, only seven (15 percent) of
the cases were Japanese and two (4 percent) each
from Palau, Hong Kong, and the Philippines.
The stress of completing an expensive diving
vacation and connecting with international flights
may explain why many divers with DCS symptoms
do not present themselves in Palau. Divers often
deny the possibility of DCI being the cause of their
symptoms, and tourists commonly mistrust local
medical facilities. Furthermore, affected Asian divers
may be reluctant to go to the Palau hospital for
treatment because of language and social barriers.
The conditions at Chuuk State Hospital, in
contrast to Palau, are very primitive. The hospital
is run down and there are severe shortages of medical
supplies and equipment. Although the U.S. Navy
installed a new, multiplace recompression chamber
in 1990, it has never been used because no
one there knows how to operate and maintain it.
Most diving occurs in deep water, where many
repetitive and decompression dives are done. As a
result, the DCI rate is much higher than normal.
Unfortunately, the nearest recompression facility is
in Guam, a two-hour flight by commercial airline.
When traveling to such areas for diving
vacations, limit the number of repetitive dives,
avoid decompression dives, do safety stops, avoid
deeper dives, do not mix alcohol with diving, and
do not fly until 24 hours after diving.
