1. How do Po2 and
Pn2 change with increasing depth? What are the consequences for
human divers as a result of these changes?
2. What is
decompression sickness and what is the cause?
3. What are some of
the common signs of decompression sickness?
4. What is the
treatment for decompression sickness?
5. Why don’t marine
animals, such as dolphins, get decompression sickness?
6. Describe some
respiratory and cardiovascular adaptations enabling dolphins to
stay underwater for long periods of time.
7. Whales can be
deep divers with seemingly no ill efects. In the article by Hooker
and Baird (1999), why do they suspect the whale dives were aerobic?
Why do whales lower their ascent rate when diving to these great
depths?
8. Once in the
helicopter, the paramedics try to stabilize both patients. Would
fying at high altitude worsen their condition? Why?
9. What are
some of the long-term efects of decompression sickness?
