CCR Divers at Inner Space Assist Decompression Research

DAN, Divers Alert Network, Dr Neal W Pollock, Jenna Wiley, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, Dr Stephen Thom, Microparticles, Decompression Stress, Divetech, Inner Space, Nancy Easterbrook, Cobalt Coast, Lighthouse Point, Jay Easterbrook, Steve TippettsHave you attended Divetech’s Inner Space and wondered why the DAN team took so many blood samples and what happened to them? They went to Dr Stephen Thom for his research.

Dr Thom gave a presentation at the ONR-NAVSEA Progress Review Meeting that took place in Durham on 15 to 17 July. He summarised the current status of his research on circulating microparticles (MPs). These are small fragments shed by various cells that have been exposed to stress and can be found in divers after diving. Here is a report on Microparticles and Decompression Stress from ‘The Dive Lab‘.

Pictured here is Divers Alert Network Research Associate I, Jenna Wiley. She is taking blood from a deep trimix CCR diver during Divetech’s Inner Space. This is then sent to Dr Thom for his research.

Dr Simon Mitchell and Dr Neal Pollock will be presenting their research at EUROTEK.2014

Are you an Auckland based diver, or live near Auckland, New Zealand? Are you available on Saturday 19th or Sunday 20th July 2014? Do you dive a rebreather or are thinking of becoming a rebreather diver? If you answer ‘yes’ to these questions, Dr Simon Mitchell and Dr Neal Pollock need your help. They are conducting a Carbon Dioxide (CO2) Prebreathe Study and need volunteers to assist in this incredibly useful research.

We are delighted to report that the findings from this study will be announced at EUROTEK.2014 in September.

What is the purpose of this research?

Rebreathers which recycle exhaled gas after removing carbon dioxide (CO2) are becoming increasingly popular in recreational diving because they offer advantages such as the conservation of breathing gas. However, they are more complex than normal scuba equipment, and there is potential for operator error in their use. These errors may lead to accidents and death. Several of these potential operator errors relate to the use of the CO2 absorbent (or the CO2 “scrubber”). If there is failure of CO2 removal from the expired breath, the diver will re-inhale CO2 and this may result in hypercapnia (commonly referred to as CO2 toxicity). Rebreather divers are taught about this during their rebreather dive training. CO2 toxicity may cause progressive shortness of breath, headache, anxiety, panic, and ultimately unconsciousness. In addition, CO2 toxicity enhances the adverse effects or toxicity of other gases such as nitrogen and oxygen. There have been many deaths during the use of rebreathers in which CO2 toxicity is thought to have contributed, though this is often difficult to prove.

The absorbent material used in CO2 scrubbers must be replaced periodically. Related errors include failing to replace the absorbent material, incorrect packing of the absorbent material into the scrubber canister, and incorrect installation of the canister in the rebreather (or forgetting to install it entirely). Most rebreather units do not monitor CO2, and so rebreather divers are taught to conduct a 5 minute “pre-breathe” of their unit just before entering the water. A prebreathe involves preparing the unit for diving, and then sitting quietly breathing on the rebreather loop. If the CO2 scrubber is absent or faulty the diver will rebreathe CO2 and, in theory, should notice the early symptoms of CO2 toxicity such as shortness of breath or headache.

Divers assume that symptoms of CO2 toxicity will occur reliably and be noted during a 5 minute prebreathe. However, this has never been formally tested. This study aims to measure the proportion of subjects who can identify the absence of an effective scrubber during a 5 minute prebreathe on a rebreather circuit. The detection of a partial scrubber failure may also be evaluated.

If you want to be part of this important study please email Pete Mesley as soon as possible to get booked in. You will be need for no more than 2 hours during the course of the weekend.

RF3 Proceedings are available for free online

The Rebreather Forum 3 Proceedings have been published in both print and electronic format following the safety symposium held from 18 – 20 May 2012 at the Caribe Royale Hotel in Orlando, Florida. Two years in the planning and two years in the writing, the 324-page rebreather publication showcases state-of-the-art and science of rebreather diving through the experience and knowledge of some of the world’s leading specialists in education, operations, physiology, medicine and safety. This meeting followed the Rebreather Forum 2 conference which was held in 1996.

The goal of Rebreather Forum 3 was to positively impact the safety of recreational, professional, scientific, media and military rebreather divers by sharing latest developments and best practices. Educational sessions took place in seminars that discussed history and evolution, medicine and physiology, business and operations, incidents and their investigation, design and testing, and training and operations. Safety was the key theme and participants were informed about the most common causes of rebreather incidents and fatalities in hopes of reducing their future occurrence. To round out the meeting, participants were able to gain hands-on experience through various pool sessions.

The 11-member, Rebreather Forum organizing committee comprised Dr. Nicholas Bird (DAN), Mark Caney (PADI), Dr. Petar Denoble (DAN), Michael Lang (American Academy of Underwater Sciences), Rosemary E Lunn (The Underwater Marketing Company), Christian MacDonald (American Academy of Underwater Sciences), Dan Orr (DAN), Dr. Neal W Pollock (DAN), Dr. Drew Richardson (PADI), Karl Shreeves (PADI) and Dr. Richard Vann (DAN).

The Editors of the RF3 Proceedings (from l to r); Dr Neal W Pollock, DAN Research Director | Dr Richard D Vann, Professor Emeritus Duke Anesthesiology | Dr Petar J Denoble, Vice President DAN Research

“We planned this Forum to introduce divers without rebreather experience to the equipment as well as to assist experienced rebreather divers in refining their skills. This was the ideal format to share ideas and listen to some of the world’s most respected experts on rebreather diving,” stated Dr. Richard Vann, former Vice President of Research, Divers Alert Network.

Publishing the Rebreather Forum 3 proceedings is a significant accomplishment by the AAUS, DAN and PADI. All three partners are very pleased to share this invaluable resource with the diving community, in order to help make diving safer. It is hoped that the knowledge gained will reduce incidents and fatalities among rebreather divers.

PDF copies of the complete RF3 Proceedings can be downloaded immediately at no-cost from the DAN website. Print copies will be available in the near-future through a print-on-demand service. More detailed information can be found at the Rebreather Forum 3 website; www.rf30.org

PADI ‘Type T’ Rebreather / CCR Checklist

Two years ago this month PADI, along with the AAUS and DAN, hosted Rebreather Forum 3. This three day safety symposium was convened to address major issues surrounding rebreather technology, and its application in commercial, media, military, scientific, sport and technical diving. Experts, manufactures, instructor trainers, training agencies and divers from all over the world discussed this technology and shared information.

The programme included dedicated sessions covering topics such as medicine and physiology, closed circuit rebreather (CCR) orientation, business and operations, CCR familiarization, training, design and testing, and incident analysis.

Associate Professor Simon J Mitchell chaired the final session at RF3 and, as a result, 16 key consensus statements were agreed and ratified by the global rebreather community. You can hear this presentation by clicking here.

Two of the 16 consensus statements agreed at Rebreather Forum 3 concerned the use of checklists. RF3 acknowledged the overwhelming evidence demonstrating the efficacy of checklists in preventing errors and two recommendations were made. These are listed below.

REBREATHER FORUM 3 CONSENSUS STATEMENTS

CHECKLISTS:

The forum acknowledged the overwhelming evidence demonstrating the efficacy of checklists in preventing errors in parallel fields that share similar technical complexity. Two recommendations regarding checklists were consequently agreed:

1. CHECKLISTS

The forum recommends that rebreather manufacturers produce carefully designed checklists, which may be written and / or electronic, for use in the pre-dive preparation  (unit assembly and immediate pre-dive) and post-dive management of their rebreathers.

– Written checklists should be provided in a weatherproof or waterproof form.

– The current version of these checklists annotated with the most recent revision date should be published on the manufacturer’s website

2. CHECKLISTS

The forum recommends that training agencies and their instructors embrace the crucial leadership role in fostering a safety culture in which the use of checklists by rebreather divers becomes second nature.

 

TRAINING AND OPERATIONS:

1. TRAINING AND OPERATIONS

The forum applauds and endorses the release of pooled data describing numbers of rebreather certifications by training agencies, and encourages other agencies to join ANDI, IANTD, and TDI in this initiative

2. TRAINING AND OPERATIONS

The forum endorses the concept of making minimum rebreather training standards available in the public arena.

3. TRAINING AND OPERATIONS

The forum endorses the concept of a currency requirement for rebreather instructors. We recommend that training agencies give consideration to currency standards in respect of diving activity, class numbers, and unit specificity for their instructors.

4. TRAINING AND OPERATIONS

The forum recognizes and endorses the industry and training agency initiative to characterize “recreational” and “technical” streams of sport rebreather diver training. These groups will have different operational, training and equipment needs.

 

ACCIDENT INVESTIGATION

1. ACCIDENT INVESTIGATION

The forum recommends that training agencies provide rebreather divers  with a simple list of instructions that will mitigate common errors in evidence preservation after a serious incident or rebreather fatality.

– These instructions will be developed under the auspices of the Undersea and Hyperbaric Medical Society Diving Committee in consultation with the relevant RF3 presenters.

2. ACCIDENT INVESTIGATION

The forum endorses the concept of a widely notified centralized “on-call” consultation service to help investigators in avoiding errors or omissions in the early stages of a rebreather accident investigation, and to facilitate referral to expert investigative services.

3. ACCIDENT INVESTIGATION

The forum recommends that in investigating a rebreather fatality the principal accident investigator invite the manufacturer of the incident rebreather (or other relevant equipment) to assist with its evaluation (including the crucial task of data download) as early as is practicable.

4. ACCIDENT INVESTIGATION

The forum endorses the DAN worldwide initiative to provide a means of on-line incident reporting with subsequent analysis and publication of incident root causes.

 

DESIGN AND TESTING

1. DESIGN AND TESTING

The forum recommends that all rebreathers incorporate data logging systems which record functional parameters relevant to the particular unit and dive data, and which allow download of these data. Diagnostic reconstruction of dives with as many relevant parameters as possible is the goal of this initiative.

– Footnote: An ideal goal would be to incorporate redundancy in data logging systems, and as much as practical, to standardize the data to be collected

2. DESIGN AND TESTING

The forum endorses the need for third party pre-market testing to establish that rebreathers are fit for purpose. Results of a uniform suite of practically important unmanned testing parameters such as canister duration, and work of breathing (qualified by clear statements of experimental parameters) should be reported publicly. Ideally, this testing should be to an internationally recognized standard.

3. DESIGN AND TESTING

The forum acknowledges recent survey data indicating a poor understanding of rebreather operational limits in relation to depth and carbon dioxide scrubber duration among trained users, and therefore recommends:

1. that training organizations emphasize these parameters in training courses.

2. that manufacturers display these parameters in places of prominence in device documentation and on websites.

4. DESIGN AND TESTING

The forum strongly endorses industry initiatives to improve oxygen measurement technologies, and advocates consideration of potentially beneficial emerging strategies such as dynamic validation of cell readings and alternatives to galvanic fuel cells.

4. DESIGN AND TESTING

The forum identifies as a research question the issue of whether a mouthpiece retaining strap would provide protection of the airway in an unconscious rebreather diver.

6. DESIGN AND TESTING

The forum identifies as a research question the efficacy of a full face masks for use with sport rebreathers.
