COPD: Incompatible With Diving

Q2 2021

Reduced exercise tolerance is common for those with chronic obstructive pulmonary disease and poses risks for diving. There can be strenuous activity involved with managing currents, swimming on the surface in choppy seas or pulling yourself and your heavy gear up a ladder and onto an unsteady boat. With COPD, shortness of breath during exertion doesn’t mean you are out of shape; it means you cannot rid your body of carbon dioxide and replace it with the oxygen needed to meet the demand of your exertion.

Exercising After a Break

Q2 2021

Sometimes life gets in the way — family obligations, unforeseen injuries, work responsibilities, social events — or perhaps the world as we know it shuts down for a while. When these things overwhelm us, many people tend to sacrifice exercise first. You may miss a few workouts, and then your exercise routine slowly slips from regular to nonexistent. It happens to most people — even fitness experts and professional athletes — at some time. Although it may feel challenging, it is possible to restart your exercise routine.

DCS in Cozumel

Matthew Brett

Q2 2021

Our checkout dive was easy, with a maximum depth of 75 feet for 50 minutes. The current was slight, and the visibility was spectacular — an ideal first dive. It closed with a nice, slow ascent and a three-minute safety stop. When we returned to the boat, I felt a sudden tingling in my right foot followed by a dull ache in my knee. I assumed the worst, thinking I had decompression sickness (DCS). When I reviewed the dive in my mind, however, that seemed impossible.

Hazards in Wreck Diving

Richie Kohler

Q2 2021

Shipwrecks lure divers as much as they attract the sea life surrounding them. The spectacle of life on a wreck, an ecosystem unto itself, is often the main attraction for divers. Nearly every ocean, sea and lake holds a world of shipwreck exploration for advanced open-water divers. Each lost ship, submarine, airplane and even the odd locomotive is a time capsule waiting for an underwater explorer to visit and photograph. Never venture inside a shipwreck until you have advanced wreck-dive training from a certified, qualified dive training professional.

A DAN member shares lessons learned while lost at sea for many hours after being carried far from the dive site by currents. It’s important to stay calm and bring your own safety gear such as a surface marker buoy. Before leaving on a trip, establish good physical fitness and always let someone know where you are and when to expect you.
