Because DCS isn’t the most straightforward diving injury, myths and misconceptions about it tend to arise. DAN is committed to continually educating divers about it, and we’ve decided to clarify a few of the most common misconceptions about it to ensure that all divers are better able to recognize DCS, respond to it and get the treatment they need in time.

While the most exotic of these potentially dangerous organisms are fairly well known, the more mundane sometimes cause uncertainty. Know what’s most likely to cause an injury on your next dive so you can relax and enjoy making bubbles.

In part one of this two-part series we’ll refresh your knowledge of wound care and treating common marine stings; next month we’ll cover injuries that involve scrapes, bites and penetrating wounds.

Interest among researchers has existed for a few decades, but it has increased in recent years as studies by such organizations as Duke University the University of South Florida have yielded intriguing results.

A recent big-data study performed by a DAN Europe research team used modern statistical analysis techniques to dig into a sample of nearly 40,000 open-circuit recreation dives and look for patterns and clues about DCS risk factors in real-world cases. Some of what they’ve found confirms our previous knowledge and opens entirely new avenues for research into the factors that contribute to DCS risk. Here’s what we’ve learned.

Diving on a blistery morning can be fun, but shivering your way through an hour of decompression can put you on a fast track to the local chamber. It is up to you to make sure that you are adequately prepared for your dive, and for the aftermath. It is easy to end up cold on a dive through no fault of your own, but knowing the signs and symptoms of hypothermia before you dive will help you know when you might be pushing things just a little too far.

These situations are especially daunting in remote locations. Learning how to respond to some of the most common medical emergencies before your next offshore trip or diving expedition could help you save a life. Do you know how to identify the early warning signs of these common emergencies?

Being tired or achy after a long dive, unplanned exertion at depth or a change in decompression planning is often not considered very seriously; if you do not have symptoms, the prevailing thinking is to not worry about it. Despite the way divers have operated for decades, researchers at the forefront of decompression research are pushing hard for greater consideration of the factors that contribute to DCS risk—factors, which combined, create a total picture of our risk.

A recent study, published in The Journal of Physiology, shows that acute oral intake of antioxidants Vitamin C and E prior to a scuba dive can reduce alterations in cardiovascular function that are caused by a single air dive.

A group of professional divers were studied before and after a moderate scuba dive to a depth of 30 meters for 30 minutes, similar to those enjoyed by countless recreational divers.
