IPE in Technical Diving — Risk & Response

IPE is the abnormal leakage of fluid from the bloodstream into the alveoli, the microscopic air sacs in the lungs. Symptoms include shortness of breath, coughing up bloody sputum, and respiratory distress. Leakage into the alveoli results in fluid buildup in the lungs, and interrupts gas exchange, similar to drowning. It is important to note that fluid resulting from IPE comes from within the body, rather than from inhalation of surrounding water.

I started cave diving in Italy in 1990. At that time, the rules were very clear, codified and related to the kind of caves that were encountered in my region. Very often, they were resurgences with current (sometimes strong) or sumps inside caves, with water ranging from crystal clear to the color of coffee and variable visibility, depending on the rains.

The beginnings of cave diving can be traced to the Wookey Hole Caves in England. And 85 years later, divers like Matt Jevon are still doing their part to discover this cavern’s full potential.

In May 2019, a group of dry cavers visited the famous silver mines of Lavrion in the southeastern area of Attica, Greece. The main objective of the visit was to inspect and document the flooded chambers.

Why Sidemount is My True DIR Diving Option

Doing something right has never been more important that being ready—and even eager—to change for the better. What was considered great a few years ago is not always great today. All we need is to find a better option, since what was right yesterday, may not be right anymore. Doing It Right (DIR) is about doing it better than it was done before. For me, that is the only right thing to do.

Bjurälven: The Underground River

The waters of Bjurälven flows from Norway’s mountains and into the Swedish province of Jämtland where the river meanders its way past the peaks and through the valley of Bjurälv where it is engulfed by the earth and disappears underground. In a thunderous roar, the great mass of water is swallowed by what is known as the Bjurälven Grotto, only to reappear more than one and a half kilometres away.
