"Hi this is John again. We’ll be talking about three different areas that will affect a diver and can ultimately cost him his life if he does not obey rules. One is air minimalism, the first and foremost rule we use in scuba is to never hold your breath when you are surfacing. As you surface the air in your lungs will expand and as you reach the surface if you hold your breath, the air will expand and rupture the capillaries in your lungs, causing damage or death. Also bends, bends is another term for nitrogen narcosis, it stands for going too deep too long. Nitrogen will build up bubbles in the blood stream and will cause cramps, paralysis and if attention is not given to it in a timely basis, it can cause death. Also, diving in the water that may be a little colder than you may be use to, even tropical water can result in hypothermia. Water will conduct heat 25 times better than air, what that means is you may not think that you are actually being cooled or chilled until you start shivering and then it may be too late. Always wear an exposure suit if you’re not familiar with the area. "

on 8/2/2008 The presenter stated that "bends is another term for nitrogen narcosis" and that is not true: nitrogen narcosis is a drunken effect of breathing compressed nitrogen at depth, usually greater than 70 feet. Bends is bubble formation of nitrogen in the bodies tissue compartments, for various reasons relating to time at depth, and rate of decompression.
