Decompression in a Hyperbaric Chamber Explained

More than 100 years ago, Sorbonne Professor Paul Bert, the father of pressure physiology, explained, “All symptoms, from the slightest to those that bring on sudden death, are the consequences of the liberation of bubbles of nitrogen in the blood [on-gassing], and even in the tissues, when compression has lasted long enough. The great protection is slowness of decompression [off-gassing].”

The Signs of a Dive Emergency

"The signs of emergencies are varied and can be subtle. They may be apparent before or during the dive. A diver's ego or peer pressure may cause the diver to disguise a problem, such as a lack of competence, inadequate experience, overconfidence, anxiety, illness, or distress. Such problems may show up on the boat before anyone gets in the water. All divers should adopt the credo of the cave and technical diving communities: Any diver can call any dive for any reason at any time. No question are asked - and the credo applies before the dive even begins. All divers should agree to this as part of the predive briefing. If more divers felt comfortable not making a dive because it was beyond their experience, or they didn't feel well, or their karma was all wrong, or whatever, there would probably be fewer problems."
