Being physically fit can be important, and sometimes crucial, for dive safety. Physical fitness plays a role in both regular dive activities and emergent events.

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.

When you surface your eyes are red, swollen, and possibly bruised. The cause was mask squeeze, a common but preventable dive injury.
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 […]
Lionfish are fascinating and beautiful creatures, but they can cause serious injuries as well as environmental problems outside their normal range.
