UNDERWATER
PROBLEM MANAGEMENT
You
can prevent or control underwater problems
by 1) relaxing while you dive, 2 ) keeping
close watch on your air supply and 3)
diving within your limitations. Of the
few problems that do occur under water,
the most likely are overexertion, running
out of or low on air, regulator free
flow and entanglement.
In
Section Two, you learned to prevent
overexertion by moving and breathing
slowly and deliberately, and by pacing
yourself: You also learned that if you
do get overexerted, stop all activity,
rest, relax and breathe slowly until
you restore your normal breathing pattern.
Underwater,
overexertion can give you a feeling
of air starvation because breathing
resistance through the regulator increases
as you go deeper. Overexertion i` the
problem, but it may feel like your regulator
isn't delivering enough air: Actually,
you're demanding more air than it can
deliver - as you recall, you prevent
overexertion (and air starvation) by
avoiding strenuous activity and by pacing
yourself'.
Running
out of air is probably the easiest problem
to avoid, and air stoppage due to a
malfunction is extremely remote (more
about this in a moment. To keep from
running excessively low on or out, make;
habit of checking your SPG frequently.
Obviously, your SPG only works if you
look at it.
