What are the three basic parts of the PADI Open Water Diver course?
What is the purpose of each part? - correct answer 1) Knowledge Development
2) Confined Water Dives
3) Open Water Dives
As a newly certified PADI Open Water Diver, I will be trained to dive with buddy as deep as - correct answer 18m/60 ft
max recreational depth limit is 40m/130 ft
What is the relationship between my depth in water and the pressure? - correct answer pressure increases by one bar every 10 meters
Depth Pressure Volume Density
0m/0ft 1 bar/ata 1 X1
10m/33ft 2 bar/ata 1/2 X2
20m/66ft 3 bar/ata 1/3 X3
30m/99ft 4 bar/ata 1/4 X4
40m/132ft 5 bar/ata 1/5 X5
Positive Buoyancy - correct answer Body weighs < displaced volume (floats)
Neutral Buoyancy - correct answer Body weighs same as displaced volume (neither floats nor sinks)
Negative Buoyancy - correct answer Body weighs more than displaced volume
(sink) How is buoyancy affected by ascending? Descending? - correct answer Buoyancy decreases as you descend.
Buoyancy increases as you ascend.
How does breathing affect buoyancy? - correct answer - Inhaling increases air volume in lungs and increases buoyancy.
- Exhaling decreases air volume in lungs and decreases volume.
Two pieces of equipment used to control buoyancy - correct answer - BCD
- Lead weights
What 3 major body air spaces does increasing pressure affect as I descend? - correct answer Ears
Sinuses
Mask
What is a "squeeze"? - correct answer A pressure imbalance where air outside
the airspace is greater than air inside the airspace, resulting in pain and discomfort.
What is "equalization" ? - correct answer Add air to the air spaces as you descend so pressure in air space equals surrounding pressure.
How do I equalize? - correct answer Ears and sinuses:
- Pinch and gently blow nose.
- Swallow and gently wiggle jaw side to side
Mask:
- Blow through nose into mask. How often should I equalize? - correct answer Every few feet before you feel discomfort
What do I do if I can't equalize?
What can happen if I don't? - correct answer Stop descending, signal buddy/instructor. Ascend slightly until it feels better then try again.
If you still can't do it, stop the dive.
Your eardrums could rupture and cause dizziness and pain. Your unequalized mask could bruise your face.
Why does having a cold prevent me from diving? - correct answer Congestion might worsen and block air flow and make equalization impossible.
Why should I equalize gently? - correct answer Doing it forcefully can cause injuries.
Why should I never dive with earplugs? - correct answer because they create air spaces that you cant' equalize
What is the most important rule in scuba diving? - correct answer Breathe continuously and never ever hold your breath.
What happens if I don't follow the most important rule? - correct answer Lung
over expansion injuries.
What is a "reverse block"? - correct answer A reverse squeeze, when expanding air becomes trapped in a body air space during an ascent.
What should I do if I feel discomfort in my ears, sinuses, stomach, intestines or teeth while ascending? - correct answer Slow or stop the ascent to allow trappes air to work its way out. Descend a meter or two to reduce discomfort and try again more slowly.
