DAN at DEMA 2019 Seminars

ALL DECOMPRESSION MODELS ARE WRONG, BUT SOME ARE USEFUL

F. GREGORY MURPHY, M.D. RM 207C NOV 15, 1PM | NOV 16, 11AM


Recreational diving is very safe, but as we push diving to the limits, going deeper and staying longer, new decompression models are needed to maintain this safety. This session will cover the decompression models in use today and prospective models for use in the future.

BREATH-HOLD AND SNORKEL INCIDENTS: WHAT WENT WRONG?

FRAUKE TILLMANS, PH.D. RM 207C NOV 14, 11AM | NOV 16, 2PM


Snorkeling doesn't require certification or medical clearance, and the equipment is cheap and easy to use. It can be a very enjoyable experience when nothing goes wrong. We will review some breath-hold and snorkeling fatalities to find out what needs to happen to make these sports safer.

BREATHING GAS CAN'T BE SEEN, SMELLED OR TASTED: HOW DO WE KNOW IT'S SAFE?

FRANCOIS BURMAN, PE RM 207C NOV 14, 10AM | NOV 16, 1PM


Operators that fill cylinders carry the primary responsibility for the cylinders' contents. However, it is the diver who is exposed to the gas in the cylinder. This talk covers fundamental principles to know and understand if you want to be more assured of your own safety.

DISCUSS A FEW CASES WITH THE DOCS

MATIAS NOCHETTO, M.D. / JIM CHIMIAK, M.D. / CAMILO SARAIVA, M.D. RM 207C NOV 14, 9AM | NOV 16, 3PM


Proper injury management can come only after timely injury recognition. Analyzing the symptom onset of diving incidents can be a valuable exercise for dive leaders. DAN doctors have prepared this special case series for you — we won't make you connect the dots backward.

FLUID MANAGEMENT FOR DIVERS: WHAT YOU NEED TO KNOW ABOUT HYDRATION

FRAUKE TILLMANS, PH.D. RM 207C NOV 13, 12PM | NOV 15, 2PM


"More Water, Less Bubbles" has become common knowledge among divers. While this is true in most cases, not everyone knows there is a "too much" in fluid consumption. In this talk, we will look at hyper- and hypohydration, the risks associated with both, and ways to estimate your fluid requirements.

HOW CAN WE BREATH-HOLD DIVE TO MORE THAN 300 FEET, AND WHAT CAN GO WRONG?

PETER LINDHOLM, PH.D. RM 207C NOV 13, 3PM | NOV 14, 12PM


High pressure while breath-hold diving affects the lungs and ears, causes narcosis, presents a risk of decompression sickness and may cause pulmonary edema. This presentation will explain how it is possible to breath-hold dive to more than 300 feet and what can go wrong from a medical or physiological perspective.

I'VE JUST EXPERIENCED A TRAUMATIC INCIDENT: NOW WHAT?

JIM GUNDERSON, BA RM 207C NOV 15, 11AM


Most people have experienced a traumatic incident at some time, either as a responder, witness or victim. This seminar covers the impact and implications of traumatic events, how events are manifested, behaviors that can result, triggers, PTSD and what we can do about all this — in both the short and long term.

LOSS OF CONSCIOUSNESS AS THE LIMIT OF HUMAN PERFORMANCE IN BREATH-HOLD DIVING

PETER LINDHOLM, PH.D. RM 207C NOV 13, 10AM | NOV 14, 2PM


A breath-hold diver has to avoid drowning by surfacing before hypoxia causes loss of consciousness. There are physiological mechanisms that increase this risk: hyperventilation, hypoxia of ascent, fasting and prolonged exercise prior to the breath-hold. How breath-hold durations of more than 10 minutes are possible will also be explained.

MARINE LIFE TOXINOLOGY: WHAT DIVE LEADERS SHOULD KNOW

MATIAS NOCHETTO, M.D. RM 207C NOV 14, 1PM | NOV 16, 12PM


Observing marine life is one of the main reasons we dive, but marine life is also why some people are afraid to dive. Tropical reefs combine nature's incredible beauty with its fiercest biochemical fury. This lecture will cover what every dive leader should know about marine toxins.

MEDICAL RISK ASSESSMENT

JIM CHIMIAK, M.D. RM 207C NOV 14, 4PM | NOV 16, 9AM


What does a medical risk assessment consist of? This presentation covers the philosophy underlying the evaluation and the specific items considered by the physician. After the evaluation, both the diver and dive professional have a role in collecting information and acting on the physician's findings. Time for questions will follow the presentation.

MEDICATIONS AND DIVING

JIM CHIMIAK, M.D. RM 207C NOV 13, 11AM | NOV 15, 3PM


This talk provides an overview of the interaction between the diving environment, medications and divers. A description of the diving environment will be followed by a practical, systematic approach to diving while taking a medication, including medications of particular interest to divers.

NOW THAT IT'S LEGALIZED …

FRAUKE TILLMANS, PH.D. RM 207C NOV 13, 4PM | NOV 15, 9AM


With the legalization or decriminalization of cannabis in several U.S. states and Canada, DAN is receiving more inquiries about cannabis and diving. This talk explores how consumption of cannabis and selected other substances can influence divers and explains why it's probably best to avoid diving under the influence.

SAFETY CONCERNS IN DIVING OPERATIONS: ARE WE REALLY PREPARED?

FRANCOIS BURMAN, PE RM 207C NOV 13, 1PM | NOV 15, 12PM


The DAN Hazard Identification and Risk Assessment (HIRA) program, established in 2011, is now available online as a self-assessment resource. A review of factors identified in the past eight years highlights the need for careful consideration of the real, everyday risks that dive businesses and professionals face.

SCUBA DIVING: A PUBLIC HEALTH PERSPECTIVE

ALLAN URIBE, DRPH RM 207B NOV 13, 1PM | NOV 14, 1PM


Public health aims to provide the maximum benefit for the largest number of people. Its principles frame our understanding of the causes and consequences of accidents, and analyzing accidents from a public health perspective can significantly reduce the morbidity and mortality due to these accidents. Join us to learn how a public health approach allows us to better analyze and prevent scuba diving accidents to benefit the entire diving community.

SCUBA DIVING FATALITIES: PATTERNS AND LESSONS LEARNED

ALLAN URIBE, DRPH RM 207B NOV 13, 3PM | NOV 14, 10AM


Join us for an epidemiological summary of this year's reported scuba diving fatalities. We will dive deep into five of the most challenging cases to highlight the risk factors for diving fatalities with the greatest prevention potential. We will also discuss the benefits of using a population health approach to prevent these accidents universally.

THE RIGHT OF REFUSAL: CAN I SAY NO?

FRANCOIS BURMAN, PE RM 207C NOV 13, 9AM | NOV 15, 4PM


Many dive operators and professionals believe that denying someone training or service can be based only on medical considerations. This is not the case. You can decline to provide service without risking a substantive claim of discrimination if you use sound, consistent and non-profiling criteria.

TOP THREE ANNOYING MEDICAL CONDITIONS FOR DIVE PROFESSIONALS

FRAUKE TILLMANS, PH.D. RM 207C NOV 14, 3PM | NOV 16, 10AM


Whether they dive at the quarry, the resort's house reef or from liveaboards, divers and dive professionals deal with various medical problems that make diving less enjoyable. We'll examine three very common ailments divers face (muscle cramps, traveler's diarrhea, and seasickness) and investigate what advice current research offers to prevent or cope with these problems.

WHAT DO YOU KNOW ABOUT GAS TOXICITIES?

MATIAS NOCHETTO, M.D. RM 207C NOV 13, 2PM | NOV 15, 10AM


This talk is intended to show dive leaders and advanced divers the toxicities of different gases from an operational point of view.
