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

12
