In Fall 2013, my wife, Liv, and I were supervising 16 new divers who were experiencing low visibility for the first time. Our training site had a maximum depth of 20 feet (6 meters) and protection from the currents that render many urban waterways challenging to shore divers. Two experienced rescue divers with excellent buoyancy […]
Pulmonary barotrauma can occur in a shallow swimming pool if a diver holds their breath during ascent or inadvertently floats to the surface while holding their breath. Most dive-related pulmonary barotraumas occur in compressed-gas diving due to pulmonary overinflation during a breath-hold ascent. Pulmonary barotrauma can occur even with normal breathing if there is an obstruction in the bronchial tree that prevents one lung segment’s normal ventilation.
DIVING INHERENTLY CARRIES AN ELEVATED LEVEL OF RISK because humans cannot survive underwater without specialized equipment. When things go wrong, an effective rescue is vital for a favorable outcome. Most rescue diver courses teach students basic techniques to apply after something goes wrong, but better courses also provide techniques to prevent incidents from occurring in […]
THE DIVE INDUSTRY IS FULL OF DEBATES. Should you use a jacket-style, back-inflate, or backplate and wing buoyancy compensator? A canister light or a cordless light? A weight belt or integrated weights? Regular fins or split fins?
WHEN ASKED TO DESCRIBE THEIR FAVORITE COURSE, many divers will discuss the challenges and triumphs they experienced during their rescue class. Instructors often describe rescue as the most rewarding course they teach. It is often the first course in which divers begin thinking about others more than themselves, so it’s little surprise that it stands […]
Being involved in a traumatic event can take a toll on everyone: dive professionals or rescue divers who perform a rescue, lay providers who help with CPR and first aid, and dive buddies or bystanders.
Interest in breath-hold diving, also known as freediving, has grown exponentially over the past decade. Most individuals who enjoy watersports have held their breath underwater at some point, but most do so without formal training or awareness of the known dangers despite the ready availability of this lifesaving information.
