Chapter 5 Flashcards
If the partial pressure of nitrogen in the air you are breathing is greater than the pressure of nitrogen in your body, your body
Ingasses nitrogen until the gas in your body reaches equal level with the gas you are breathing
If pressure is lowered too quickly, excess nitrogen absorbed by a diver can come out of solution within the tissues and causes
Decompression sickness/bends
The nitrogen remaining in your system from a previous dive is called
Residual nitrogen
The elapsed time from the moment you begin your descent to the time you return to the surface, excluding ‘safety stop’ time is
Actual Dive Time
A stop at 5 meters (15 feet) fro 3 minutes as a safety precaution is
A precautionary decompression stop
Your surface interval must be at least what to use the Table 2
10 minutes between dives
NAUI recommends a surface interval time of at least
1 hour
Use what depth to determine your dive schedule?
Your deepest depth
When making a series of dives you always
Make your deepest dive first
If you become chilled during your first dive
Use the next greater dive time when finding your letter group
Consider any dive shallower than 12 meters (40 feet) to be a
12 meter dive when planning repetitive dives
If you are using the NAUI Dive tables, you make a precautionary or decompression stop at a depth of
5 meters
If you are planning to fly after making multiple no-decompression dives, NAUI recommends you
Wait at least 12 hours
You must follow special dive tables and procedures when diving at altitudes great than
300 meters
A ceiling display on a dive computer indicates the depth to which you can
Ascend at that particular time
