Divers Rescue Seminar

Yesterday, I attended a free seminar on in-water rescue and post rescue management, by John Lippmann of DAN Asia Pacific. The talk was rather general, neither prescribing very concrete behavior, not diving too deep into medical theory. Instead it was rather broad, touching various angles, and describing historic developments. I am not sure if beginners should hear talks like this, as they can be too confusing (instead of giving practical rules). For an advanced audience, the talk was a bit shallow. Answers to questions however were very detailed and showed a deep understanding. John really knows his stuff.
Personally, I learned the importance of keeping dive accident victims horizontal, to avoid bubbles rising to the brain. I must have read about this before, but not realized its importance.
The talk was organized by Alex Poon of Divers Kinetic, a non-profit Hong Kong dive club. He was a great guy, down to earth and very open. Seems like I will join DK.
