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.

Stings & Scrapes — Part 2

Stingrays

Stingrays are frequently considered dangerous or threatening but largely without cause. These are shy fish that generally present no threat to divers unless stepped on or deliberately antagonized. Most stingray injuries occur in shallow water when beachgoers step on the animals. Stingrays can vary in size from just a few inches to more than six feet wide and have a serrated barb at the end of their tails that can cause serious injuries. At the base of the barb are two venomous glands that can cause infections and exacerbate an initial penetrating wound.

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.

Surviving Lockdown

For most of us in lockdown during the coronavirus pandemic, being away from diving in itself is enough to cause withdrawal symptoms. Sometimes, factors such as work, weather and lifestyle can mean that we take longish breaks, although I do not think anyone has taken such a long break before—certainly not one that left no choice and one that required significant lifestyle changes and restrictions.

DAN Publishes Guidelines for Lifelong Medical Fitness to Dive

The document, which is intended to be used by divers, dive professionals and doctors, establishes a schedule for medical questionnaires and physical evaluations based on age and other relevant factors. 

“Scuba certifications are generally valid for divers’ entire lives, but everyone’s health status changes over time,” said DAN medical director Jim Chimiak, M.D. “Our goal with this schedule is to provide useful guidance that divers can rely on to feel safe and confident in the water.”

Diving in the era of COVID-19: How do we safely go diving again?

April 2020 — I come to you as a recreational and technical diving instructor, as a physician consultant for Divers Alert Network, and as a COVID-19 survivor. For me, it was just an occupational hazard. I tested positive for COVID-19 after seeing a patient in my cardiology clinic for an unrelated condition who seemed quite short of breath. He was admitted to the ICU and tested positive for COVID-19.
