The Denial that Damaged my Brain

DCS can be a very subtle sickness, something we can easily deny and put down to the tiredness of a busy dive schedule, or change of routine. But the effects, even after treatment, can be lasting.

Even though DCS might seem subtle, it could be serious. DAN AP Member Alice Grainger shares her experience of denying her decompression sickness due to the lack of the usual physical symptoms, until she decided her brain clearly wasn’t working, and went to seek medical help. With comments by DAN AP Founder, John Lippmann. Continue reading “The Denial that Damaged my Brain”

Flying After Diving – what are the risks?

You may have heard of divers who fly less than 12-hours after diving with no negative impact and others that wait a longer period who end up with symptoms of DCI and wondered why this happens. Dr John Parker, a Diving physician and Senior Dive Medical Consultant for DAN, discusses this issue.

How you can save over $10,000 on your next Dive Trip

An Australian living in India, on a 6-day diving holiday in the Maldives, diving ‘safely’ according to her dive computer, suffered decompression illness (DCI) with peripheral neurological symptoms. Total bill: A$11,000+. Fortunately, she was a DAN AP Member.

Ever tried Jellyfish soup? – snorkelling in it that is!

There is a lake in Palau full of jellyfish, which are completely harmless and you can snorkel amongst them. It’s a bit like snorkelling in a warm, green jellyfish soup.

There is a lake in Palau full of jellyfish, which are completely harmless and you can snorkel amongst them.  “How many jellyfish exactly?” seemed a fair question, but “Between six and twenty million” wasn’t the answer we were expecting from our otherwise precise and accurate dive guides Richard and Paul from Unique Dive Expeditions at Sam’s Tours.

The next question was obviously ‘how?’ How does it happen that on one island of the small archipelago of Palau, in the middle the Pacific Ocean, in a completely enclosed lake, there lives a colony of jellyfish, who have lost their ability to sting, and therefore kill, anything?  Being jelly FISH – these guys are obviously not living off fresh air. How does that work? Continue reading “Ever tried Jellyfish soup? – snorkelling in it that is!”

When to Call a Dive

In this article, DAN Asia-Pacific’s General Manager, Scott Jamieson, discusses the importance of knowing your personal limits and when to call (or abort) a dive

In this article, DAN Asia-Pacific’s General Manager, Scott Jamieson, discusses the importance of knowing your personal limits and when to call (or abort) a dive.

During our basic dive training we are taught that if a dive doesn’t feel right we should abort it. The reality is, despite these lessons, many people find themselves on dives for which they lack the confidence or experience to be undertaking. This places unnecessary stress on the diver, both physically and mentally, and this can lead to unnecessary incidents involving injury or even death. Continue reading “When to Call a Dive”

Yonaguni Monument – lost underwater temple or natural feature?

In the remote island of Yonaguni, Japan’s most south-westerly point in the province of Okinawa, an underwater feature has archaeologists and geologists still arguing 30 years on

In the remote island of Yonaguni, Japan’s most south-westerly point in the province of Okinawa, an underwater feature has archaeologists and geologists arguing, still, 30 years after it was first discovered. Is it an ancient monument, the remains of a legendary city like Atlantis, swallowed by the ocean thousands of years ago? Was it built by aliens? Or is it a natural rock formation? Continue reading “Yonaguni Monument – lost underwater temple or natural feature?”

But I Was Within The Limits of My Diving Computer!

Most divers these days use dive computers and appear to be reasonably confident that by doing so they will avoid decompression illness (DCI) as long as they dive within its limits. Dive computer algorithms are based on decompression models, which are only generalisations and deeper dives, longer dives, with shorter surface intervals produce less accurate decompression calculations.

Most divers these days use dive computers and appear to be reasonably confident that by doing so they will avoid decompression illness (DCI) as long as they dive within its limits.

One DAN Member, who called for help, commented: “But I didn’t believe it could be DCI as there were no violations according to my computer”, a relatively common reaction.

John Lippmann DAN Asia-Pacific’s Founder, Chairman & Director of Research explains why deeper dives, longer dives, with shorter surface intervals and repetitive diving, can often be inviting problems. Continue reading “But I Was Within The Limits of My Diving Computer!”
