    6. Training standards 1960s Accident rates for scuba divers increase NAUI (National Assoc of Underwater Instructors) Formed in 1960 More rigorous PADI (Professional Assoc of Diving Instructors) Formed in 1966

    7. Basic Concepts You are under pressure while diving The deeper you go, the more water pressure you experience Air tank supplies you with air at pressures equal to the surrounding water Air-filled spaces-you must breathe! Lungs, sinuses, middle ear All these spaces must be filled with air equal to surrounding pressure No diving with cold, sinus congestion or anything that restricts movement of air between these spaces

    8. Basic Concepts You must breathe all the time while diving NEVER hold your breath while breathing compressed air As you ascend, the surrounding water pressure decreases Air expands as you ascend Breathe naturally to vent this air Learning to control your buoyancy

    9. Basic Concepts What if I run out of air? Guage, extra regulator What if I get too excited? What if something goes wrong? Why you get certified What if I see a shark? Most experienced divers have never seen a shark

    10. Decompression sickness Air= Oxygen + Nitrogen Oxygen At the surface Balance of Nitrogen consumed and eliminated Under increased pressure Concentration of Nitrogen is increased Balance is upset After spending time under pressure, quantity of Nitrogen increases in your tissues Idea is to control amount absorbed and rate it is eliminated

    11. Decompression sickness As you ascend, outgassing occurs Excess nitrogen passes from the body tissues to blood to lungs and is expired If change in pressure is sudden Nitrogen comes out of solution suddenly Bubbles form in body tissues The bends
