PADI Open Water Diver Certification
SCUBA - ANSSelf contained underwater respiration equipment
What is the strain alternate for every 10m/33ft of depth exchange? - ANS1 bar/1 ata/1
environment
What is the connection among my intensity in water and the pressure? - ANSThe deeper you go
in water, the greater the stress increases
Pressure is expressed because the weight of air
What is the relationship among strain, and the extent and the density of air? - ANSAs pressure
increases, the gasoline quantity decreases and the gas density increases
If I take a volume of air from one intensity to every other intensity, how a lot will the extent and
density alternate? - ANSVolume may be 1/ata#
Density could be ata#
What three foremost frame air areas does growing stress affect as I descend? - ANSEars,
sinuses, masks
What is a "squeeze"? - ANSThe soreness as a result of pressure imbalance pulling tissue into
the air space
What is "equalization"? - ANSThe addition of air in your air spaces as you descend
How do I equalize as I descend? - ANSFor ears and sinuses, pinch your nose and blow gently,
or wiggle your jaw and swallow
For masks, blow into it with nostril
How regularly should I equalize? - ANSEvery meter/few feet, BEFORE you feel soreness
What must I do if I cannot equalize? - ANSStop your descent, signal problem and factor to your
ear, ascend a piece, and try once more
What can occur if I do not or cannot equalize gently and preserve descending? - ANSFluid can
rupture the eardrum
Bruising across the face can occur
Why does a congestion from a cold or hypersensitive reaction quickly maintain me from diving?
- ANSCongestion may block ordinary air glide, making equalization hard or impossible
, Why have to I never dive with earplugs? - ANSThey create air spaces that you can not equalize
What different frame air spaces are tormented by growing pressure? How do I equalize them? -
ANSIn crammed tooth - visit a dentist
In a dry healthy - learn from an instructor
Lungs - breathe commonly and continuously
What is the most crucial rule in scuba diving? - ANSBreathe constantly and never maintain your
breath
What can happen if I don't observe the maximum critical rule in scuba diving? - ANSYour lungs
will over amplify and rupture
What is a "opposite block"? - ANSWhen increasing air becomes trapped on your body air
spaces as you ascend
What need to I do if I feel discomfort in my ears, sinuses, stomach, intestines, or teeth at the
same time as ascending? - ANSStop your ascent and descend a meter/few ft to lessen
discomfort and give trapped air time to work its manner out
How does intensity have an effect on how long my air supply lasts? - ANSThe deeper you are,
the greater dense air you breathe, and the quicker you use the air in your cylinder. Compared to
the surface, air supply lasts 1/#ata as lengthy in conjunction with other elements
What's the most green manner to breathe dense air underwater? - ANSTake gradual, deep
breaths
How do I breathe to lessen anxiety while underneath strain? - ANSDo NOT breathe quicker -
preserve respiration slowly
What are my 4 respiratory policies as a scuba diver? - ANS1. Breathe constantly and in no way
preserve your breath
2. Breathe slowly and deeply
3. Don't permit your self to get winded or out of breath
4. If faced with a trouble, forestall, and reduce anxiety by respiration slowly and deeply
What is buoyancy? - ANSAn upward force acting on an item in the water, canceling the pull of
gravity
What reasons buoyancy? - ANSThe upwards force is as a result of the water displaced through
the object, and is identical to the weight of displaced water
high quality buoyancy - ANSThe object weighs less than the water it displaces, so it floats
