Measuring Decompression Stress
Presented by Neal Pollock, PhD
The outcome for a given dive can simply be described as safe
or unsafe, but the effects can actually be far more subtle. This
presentation will consider how decompression stress can
be evaluated, the major factors that influence it and practical
strategies to control risk.
Myths & “Facts” in Diving Physiology
Presented by Neal Pollock, PhD
Information shared as both “myths” and “facts” can often be a
confusing mix. This presentation will discuss both scientifically
proven physiology facts as well as unsubstantiated theories that
have circulated around the diving community.
Pathophysiology of Immersion
Presented by Neal Pollock, PhD
Water can be a joy to swimmers and divers. The buoyancy water
provides enables us tomove in three dimensions with tremendous
freedom. There is a toll, however, that comes with this dense
milieu that we do not see in our normal air environment. This
presentation will consider the effects of water immersion and the
implications for swimmers and divers.
PFO & Recreational Diving
Presented by Douglas Ebersole, MD
Is there a relationship between patent foramen ovale (PFO) and
decompression illness (DCI)? This presentation will discuss the
anatomy and physiology of PFO and its relevance to recreational
scuba diving. Specifically, it will present the data regarding
the increased incidence of DCI in divers with PFO and ways
to mitigate this risk as well as an update on the ongoing DAN-
sponsored study of PFO and DCI.
Project Dive Exploration: 1995-2008
Presented by Richard Vann, PhD
The goals of Project Dive Exploration (PDE) were to measure the
DCS incidence at selected recreational dive sites and investigate
the primary risk factors. Results indicated a very low DCS
incidence for basic recreational diving, a higher incidence for
occupational exposures, and the highest incidence for advanced
diving. Within each form of diving, a model of dive profile severity
was highly predictive of DCS incidence. Nitrox diving gases in
the vicinity of 32% oxygen were found to be used to dive deeper
than air but with no higher DCS incidence.
Routine Activities That May
Increase Risk of DCS on a Dive Trip
Presented by Dario Gomez, MD
Daily activities can increase risk of DCS, but certain measures
can be taken to decrease the risk during a dive trip. This seminar
will cover the known statistics and general recommendations.
Learn simple steps you can take to mitigate risk.
What to Expect from Hyperbaric
Treatment and How it Heals DCS
Presented by Dario Gomez, MD
Hyperbaric oxygen is the definitive treatment of DCS. This
discussion will serve as an introduction to hyperbaric chambers,
treatment tables, additional therapies as well as outcomes and
statistics for DCS. This seminar will also cover basic physiology
and mechanisms of hyperbaric oxygen.

Online Incident Report
DAN has established an online dive safety reporting system,
designed to enable divers to anonymously report nonfatal accidents and
the details surrounding the event.
The data gathered will help identify trends and establish baselines
to further research efforts and enhance the safety of our sport.
