Developing Oxygen Toxicity Guidelines

In 1943 a hyperbaric chamber in London reached an air pressure equal to 300 feet (91 meters), and nitrogen narcosis hammered the three dry divers inside. They reached for the rubber mouthpieces of their dive gear, which delivered 100% oxygen.

Wearing Contact Lenses While Diving

Many divers wear contact lenses without issue during their dives. It’s crucial, however, to be aware of potential challenges, such as increased dryness or irritation due to factors like dry air in the dive mask, prolonged wear, mask squeezes, or exposure to saltwater. Maintaining good hygiene practices, including thorough handwashing before handling lenses and avoiding contamination, is essential.

Monitoring Dive Incidents and Drug Use

The day-to-day tasks of injury monitoring at Divers Alert Network include tracking dive fatalities by sifting through emails, news alerts, and social media to collect information about recent events. Our goal is to report to the dive community our findings on what people report to us or what we encounter in our research.
