Advanced Decompression Physiology


To Be Determined


Since Dr. Powell needs to fly in from the Seattle area, we need a commitment to attend from at least ten (10) people to schedule this class. If you have a class, dive club, or general group of divers who would to attend this class please contact the Chamber at 310-510-4020 (or Please provide us with a couple weekend options for the class and a lead time of at least one month.

Course Synopsis

Join Dr. Michael Powell on a fascinating journey into "Advanced Decompression Physiology."

This program has evolved from requests for a class on diving physiology that would be suitable for advanced divers and diving leaders eager to understand the forces at work on the ocean within the body during decompression. This course is taught from the aspect of gas phase (bubble) dynamics instead of from the vantage point of decompression table theory. Students will learn what bubbles actually do inside living organisms rather than what is considered "safe" or "unsafe" according to decompression tables or dive computers.

Starting with a historical perspective of decompression research, this course covers aspects of gas exchange; oxygen and oxygen toxicity; and Doppler bubble detection. Most of the program will focus on bubble development and growth; decompression sickness; gas phase research; bubble control; and the influence of diving decompression research on space decompression and vice versa.

This class is a must for any diver curious about the forces affecting them on every dive, and especially for those divers who think they know what is going on.


Accommodations and meals are included in the tuition. Participants will be housed in the Wrigley Institute for Environmental Studies dorm rooms and apartments. Meals are served in the Institute's cafeteria.
