What can be learned about the risk of decompression sickness (DCS) by examining thousands of actual dive profiles and their outcomes? Plenty! Here Diver Alert Network’s...
Anyone who’s dived to 30 meters on nitrox (we don’t do air here!) is familiar with what Jacques Cousteau eloquently termed “rapture of the deep”—the result...
Just like skeletal muscles, respiratory muscles have a limited ability to respond to respiratory loads, and when they can’t keep up underwater due to increased gas...
