DAN Enhances Return To Diving Guide With Video

Wed, 07/07/2021 - 20:40

Available at DAN.org/Return, the guide has helped thousands of people get back in the water safely in the past few months. Now, this new video brings the guide to life, highlighting the essential elements of a safe and successful return to diving after time away. 

Stings & Scrapes - Part 1

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.

DCS Risk Factors

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.

Hypothermia & Diving

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.

Understanding the Future of Decompression Risk

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.

Can Antioxidants Protect Scuba Divers?

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.
