Decompression dives by definition "push" the limits of the diver's adopted decompression algorithm. Accurate data on the incidence of decompression illness (DCI) in technical diving are lacking, but there is anecdotal evidence that mild forms are relatively common in repetitive multiday decompression diving. The basic principles of diagnosis and first aid treatment of DCI are relatively well understood by technical divers, but there are often tensions between "textbook approaches" and pragmatic solutions to real-world problems on technical diving expeditions. The issue of field management of DCI was recently reviewed by a committee of international experts and the key results of that review will be published in Diving and Hyperbaric Medicine in March 2018. TEKDive USA will be the first public discussion of them. This presentation will summarize the committee's findings, framed in a way to be relevant to technical divers and the particular challenges of technical diving expeditions. In-water recompression, will be covered in a separate presentation by Dr David Doolette who was a member of the committee.
TEKDiveUSA.2018 will feature a panel discussion by some of the brightest minds in scientific diving and medical research. They represent a variety of backgrounds and interests that should make for a lively discussion of developments in safety management and diving research. Join Dr. Simon Mitchell, Dr. Neal Pollock, Dr. David Doolette, Doug Ebersole MD, Andrew Pitkin MD, Moderated by Dr. Dawn Kernagis April 27th-29th, 2018 in Orlando, Florida at TEKDiveUSA.2018
In June 2017 a committee of diving medicine experts revised guidelines for the prehospital management of decompression illness. This committee noted that recompression and hyperbaric oxygen administered in a recompression chamber is acknowledged as the gold standard of care for decompression illness. However, the committee recognized the reality that divers trained in underwater oxygen breathing – including technical divers – are diving in locations remote from recompression chambers. He committee stated that in locations without ready access to a suitable hyperbaric chamber facility, and if symptoms are significant or progressing, in-water recompression using oxygen to a maximum depth of 30 fsw is an option. This is only appropriate where groups of divers (including the “patient”) have prior relevant training that imparts an understanding of related risks and facilitates a collective acceptance of responsibility for the decision to proceed. The committee expanded on some of the qualifications in the preceding statement, and added that in-water recompression should not be conducted if there is hearing loss, vertigo, vomiting, an altered level of consciousness, shock, respiratory distress, or a degree of physical incapacitation that makes a return underwater unsafe. Also, in-water recompression may not result in complete resolution of decompression illness, and signs or symptoms may recur. Any injured diver completing an in-water recompression procedure should be discussed with or reviewed by a diving medicine physician at the earliest possible opportunity. Data does not exist to establish the benefits of in-water recompression compared to the widely supported first aid of surface oxygen and transport to the nearest recompression chamber. This talk will review the evidence that this committee used to reach their cautious, qualified endorsement of in-water recompression in some circumstances.
Since the beginning of time, humans have wondered what lies beneath the ocean. As technology has moved on we have been able to go deeper or stay down longer, but the time available at depth on deep water archaeological sites is limited by Physics and Physiology. Our ability to document what lies on these deep sites has been limited to a few photographs, or some video, but it has not been realistically possible to properly research and document these sites. With the advent of digital photogrammetry it is now possible for us to scan a wreck site and bring back high resolution digital 3D models that are accurately scaled and can be used to show exactly what lies beneath. John Kendall is a GUE Tech and Cave instructor and for several years has been involved with GUE's projects across the world. He will be presenting some of the findings of these projects as well as talking about how Photogrammetry works, and how it can be useful for divers.
Talk with a panel of professional explorers, underwater archeologists, tech instructors, manufacturers and photographers about how they’ve progressed from a young age and made a career in the dive industry. Hear about what inspired them to keep moving up in technical diving and the different paths that got them started. The Panel will discuss ideas on how to inspire the next generation of divers, internships, scholarship opportunities and mentoring. Hear about how to start technical diving, and the best way of getting younger divers interested in not just diving but advanced diving. It is possible to do it at a young age and the panel is excited to share their stories and experience to help others take the first steps into a world we all are passionate about.

Join attorney David Concannon as he examines legal hits and misses from the courtroom to cave diving, recent trends in litigation involving technical diving, case studies and tips for avoiding seeing him sitting opposite you or beside you at the defense table. David has represented clients in the diving industry for two decades, he has not lost a trial in 23 years, and he is actively involved in accident analysis and investigation. He will candidly share insights that will help you avoid becoming either a defendant or a statistic, in a warm and friendly environment that is open to friends and enemies alike.
Join Gareth Lock for this TEKDiveUSA.2018 presentation. Checklists have been proven to improve safety and reduce incidents and accidents in a variety of high risk domains including aviation, healthcare and the nuclear industry. However, the design, uptake and usage of checklists is not great when it comes to the diving industry, leading to an associated reduction in safety. This engaging and challenging presentation will highlight why checklists are doomed to failure in technical diving unless their real purpose is understood and explaining why relying on them to solve the safety problem is flawed. Notwithstanding this, Gareth will identify ways in which checklist use and their effectiveness can be improved by taking a systems view to their design and deployment.
This presentation by David Concannon and Gareth Lock will look at the significant challenges involved in resolving the conflict between the litigious nature of society, which protects information and seeks to assign fault, and the need to share detailed and context rich information to show how and why incidents and accidents occurred so that risk can be managed effectively. The session will address both sides of the issue, with each presenter making their case and offering solutions. Next, the floor will be opened for questions. There is unlikely to be a clear answer but rather the aim is to generate discourse and mature discussion on the ways we can learn from individuals’ and systemic failures.
Join Dr. Simon Mitchell and Dr Nick Gant for this TEKDiveUSA.2018 presentation. When divers start using mixed gases for deep diving, and / or rebreathers, we almost inevitably create opportunities for mistakes that might lead to us inspiring a gas that contains insufficient oxygen to maintain normal body oxygenation. Examples include operation of a rebreather with the oxygen cylinder turned off, or mistakenly using an hypoxic bottom gas during shallow decompression on open circuit. The result of such mistakes is progressive reduction of oxygen levels in the blood (hypoxia). Hypoxia is an insidious condition. It often gives little warning of onset, particularly if there are other distractions. Unlike hypercapnia, which usually produces unpleasant symptoms, a diver can easily pass through a stage of confusion and lapse into unconsciousness with little or no sense that anything is wrong. We have recently been conducting experiments in which human subjects are intentionally rendered very hypoxic whilst trying to perform a mental task, and the video records of these events are educational viewing for divers. In this presentation we will discuss how hypoxia can occur in diving, and how failure to recognize its onset is common. We will illustrate these principles with video and results of our recent experiments. Finally, we will discuss the safety and usefulness of intentional "dry hypoxia experiences" that have occasionally been advocated for divers, and why we don't think these are a good idea.
Join Douglas Ebersole, MD, Cardiology Consultant at Divers Alert Network and Interventional Cardiologist at Watson Clinic LLP Lakeland, Florida for this special TEKDiveUSA.2018 presentation. Immersion pulmonary edema is a life threatening condition that affects both surface swimmers and divers and frequently occurs in otherwise healthy, or even athletic, individuals. Symptoms can present suddenly at any point during a dive and include shortness of breath, confusion, loss of consciousness, and even death. The precise incidence is unknown, because fatal cases can be mistaken for drowning. Most information about this condition comes from survivors, some of whom have recurrent episodes. This presentation will discuss the incidence, signs and symptoms, therapy, and prognosis for this condition in a case presentation format.

Why do some regions in the world have a cohesive community of divers who achieve things that completely exceed our expectations and defy our assumptions on what is possible for a technical diving community? Join us at TEKDiveUSA.2018 for a panel discussion on technical diving hot spots with German Arango, Tom Steiner, Joanna Mikutowicz, Guy Shockey, and moderator Lauren Kieren.
A technical diving hotspot is a community of divers in a particular area or region who share a common spirit and inspire enthusiasm and commitment within the team and hold a strong regard for the development of diving standards and safety for the group.
Why do some of these communities achieve great success while others with the same resources and potential fail?
What makes locations like (Buddy Dive Bonaire, Divetech Grand Cayman, Pacific Northwest, Go Zo Technical in Malta) so unique in technical diving and how did these locations become the hotspot they are today?
These are some of the questions we will ask in the panel discussion, Building a Technical Diving Hotspot. You may be surprised to find that you too can create your own tech diving hotspot anywhere in the world to share ideas, train, dive and travel with.
