SSI Open Water Diver – Section 3 Study Guide, Key Concepts & Skills Review
An overexpansion injury characterized by swelling in the neck area with a cracking sensation
upon touching the swollen area - ANS ✔✔Subcutaneous emphysema
The major, and most common, symptom of decompression sickness - ANS ✔✔Joint pain
The transfer of oxygen and nitrogen into the bloodstream occurs through its walls - ANS
✔✔Alveoli
The most serious lung overexpansion injury - ANS ✔✔Arterial Gas Embolism
If a flexible air-filled container at 100 feet of sea water has a volume of 10 cu ft, what would be
the volume if it were transported to the surface? - ANS ✔✔40 cu ft
Decompression sickness occurs when: - ANS ✔✔Excess Nitrogen bubbles out of solution into
the blood and tissue,
The nitrogen tissue tolerance gradient is exceeded,
and
A diver stays at a depth too long and surfaces too quickly
Haldanes theory that the human body can withstand a 2:1 pressure difference was revised by D
Workman to a nitrogen ratio of: - ANS ✔✔1.58:1
