A medical guide to handling interactions with marine creatures
By Joseph Becker, M.D. and Paul Auerbach, M.D., M.S.
No matter how careful they are, sooner or later most divers are stung, bitten, punctured or poisoned by a marine animal. While a healthy respect for marine life and the environment is a good safety measure, accidents happen and serious afflictions may result.
Sharks are commonly thought of as the animal most likely to cause injury, but in truth, there are many other marine animals that are more likely to injure divers. Creatures such as barracuda, seals, otters and eels – while not normally aggressive – may sometimes react defensively and bite humans. Continue reading “When accidents happen…”
Remnants of the Second World War can be found scattered throughout the Pacific, from the jungles and lagoons of Micronesia and Papua New Guinea to Pearl Harbour in Hawaii. One of the most famous (and largest) wrecks however, is found somewhere in between, in Vanuatu: the SS President Coolidge.

Koh Ha is a tiny group of islands not far from Koh Lanta on Thailand’s south west coast. The tall rocky limestone karst islands are very picturesque, like many of the islands in this part of the world, similar to Koh Phi Phi and the so-called James Bond island in Phang Nga. But the real beauty of these islands is to be found underwater. Continue reading “Koh Ha: Thailand’s royal dive destination”

Almost half of those who are treated with hyperbaric oxygen therapy have some neurological symptoms or pain for several days or weeks after hyperbaric therapy was completed. On average, 16 percent of injured divers will still have symptoms for up to three months after they have been treated.
DAN was contacted by a diver who had received eight hyperbaric treatments for decompression sickness six weeks ago. He was in good physical shape and an hour after diving he experienced numbness and tingling in his left arm, hand, leg and foot and felt very weak and fatigued. At the end of his treatments all his symptoms had alleviated and four days later he flew home without issue. However, he reported that in the last two weeks he had noticed a return of some of the tingling in his left arm and foot that comes and goes but doesn’t completely go away. He was wondering if this was a normal side effect of decompression illness and whether he should seek further recompression. Continue reading “Decompression Recovery”
