Oxygen Seizures at PO2 ≤ 1.6 Bar: How Rare? - Shearwater Research

Interesting read, something not commonly taught...



beware of CO2!  If PO2 ≤ 1.6 bar and a diver is breathing easily, the risk of CNS oxygen seizure is extremely low unless the scrubber breaks through

Colorful Fiji

The South Pacific Fijian waters – known as the soft coral capital of the world – makes for an unforgettable respite from the daily grind.

Fiji is an exotic holiday destination in the heart of the South Pacific with more than 300 islands. The major islands Viti Levu and Vanua Levu is where most of its population resides. Fiji is famous for shark feeding and soft coral diving, white sandy beaches and a pristine natural environment, with something for everyone.

Only four hours from Sydney to Nadi airport, I arrived without jet-lag and headed for the water straight on arrival. I took two weeks to discover some of the many dive sites in Fiji and for good measure, included a liveaboard to the mix.
I arrived a couple of days early just to get myself ready for the liveaboard, and to make sure all my diving gear and camera equipment arrives unscathed. It is important for me as I had encountered problems before when my luggage didn’t arrive on the same flight.
The 40m luxury Fiji Siren liveaboard departs Volivoli Beach resort located in the northernmost tip of Viti Levu, about 2.5 hours from Nadi airport. The Resort has comfortable, clean rooms all with ocean views, and its own dive operator. It is a great starting-point for dive gear and camera equipment checks as well as to reccce Fiji diving conditions.
From the resort I could see the Fiji Siren anchored and waiting for me to go and explore diving with her. The Fiji Siren is a 40 meter luxury liveaboard with a maximum of 16 divers on each trip. The 8 large air-conditioned cabins are luxurious twin or double rooms with ensuite bathroom and hot water. The Fiji Siren has designated indoor and outdoor workstations with charging points and large storage drawers, easy and convenient for every diver with a camera. There is a large dive deck with 12L tanks and nitrox.
My 10-day journey began with “Bula” (or “welcome” in Fijian) and the crew played guitar and sang their hearts out to welcome guests. The crew director Rani had a good sense of humour which kept everyone engaged and entertained on the trip.

DAN Asia-Pacific Safety Tip: In-Water Recompression

Written by John Lippmann Founder & Chairman DAN Asia-Pacific
In-water recompression (IWR) has been used in one form or another for many decades as a means of trying to eliminate symptoms of decompression sickness (DCS). Historically, it was predominantly used by diver fisherman in places where there was no access to recompression chambers or suitable medical care.
dan-breathing-oxygen-stephen-frink2
Protocols varied, but it often involved descending to depth (often 30-50 m) breathing air. The reality was that it was fraught with risk for both the diver and his buddies and there are many anecdotes of poor and sometimes tragic results.
In an effort to reduce the depth required for IWR, several organisations introduced IWR protocols which used oxygen, rather than air, as the breathing gas. Possibly the best known procedure was that introduced by Dr Carl Edmonds, of the Australian Navy School of Underwater Medicine.
The treatments involve the injured diver re-submerging to a specified depth (usually 6-9 m) for scheduled times breathing 100% oxygen. However, the breathing of oxygen can cause seizures at these pressures so, to mitigate the risk of drowning in the event of a seizure underwater, the diver is advised to wear a full face mask.  In the Edmond’s procedure, the diver is also tethered to a shotline marked in 1 metre increments to control the depth and later the ascent rate (which is 1m / 12 minutes).  There needs to be an underwater attendant with the diver and one on the boat. The sea and weather conditions need to be suitable and the diver needs to be wearing an appropriate wetsuit or drysuit to ensure that he/she doesn’t get cold during the several hours underwater. The treatment time ranges from about 2 to 3.5 hours.
With the emergence of technical diving, the breathing of high oxygen concentrations underwater has become commonplace; as has diving in more remote locations. The availability of rebreathers enables oxygen-breathing for extended periods. As a result, there are an ever-increasing number of anecdotal reports of divers with symptoms of DCS treating themselves using IWR on oxygen (IWOR). If done in a reasonable fashion, this is often successful. However, the reality is that it is often done in a relatively haphazard manner, increasing the risk of a problem.
Over recent months, DAN AP has received two concerning reports involving IWOR. The first involved a technical diver who was diving in Indonesia. He developed mild symptoms of DCS after diving and decided to do a shallow dive on his rebreather on a high PPO2 to try to resolve them. Although the symptoms receded for a while, they worsened again that evening. After searching the web he found some IWOR procedure on a chatline and dived again the next day, trying to treat his symptoms. Unfortunately, they became far worse and he further compounded them by flying home.
The second diver developed symptoms of decompression illness after diving from a ’liveaboard’ in the Philippines. He was unconscious for a short time. The dive crew called the DAN AP Diving Emergency Service (DES) hotline and was linked to an experienced diving doctor. The operator indicated that its protocol was to use IWOR and asked the doctor for advice. The doctor advised that the diver should NOT be put in the water due to his unstable condition and that he should remain on the boat and breathe oxygen for several hours while arrangements could be made for further management. The diver improved significantly with the oxygen first aid, but, despite this and against the medical advice, the dive operator insisted that the diver do IWOR. Had he become unconscious whilst underwater it could have ended in a fatality and the dive operator’s position would likely be indefensible given that they had acted contrary to expert medical advice.
It is not the role of a dive professional to make what is essentially a medical decision to perform IWOR on a client. Unless they are particularly well-informed, the client would not be in a position to assess the potential risks and balance them against the possible advantages. This is also true of the dive professional.
I believe that IWOR has its place in the management of DCS in remote places. However, it must be done using acceptable protocols, with appropriate equipment, in appropriate conditions and only on a diver who is conscious and stable. Expert diving medical advice should be sought and followed.
Dive operators and divers should not underestimate the effectiveness of properly delivered surface oxygen first aid. If given early, in high enough concentrations and for long enough (often 4-6 hours), oxygen first aid will often reduce or eliminate symptoms of DCI. It is essential that there is an adequate oxygen supply that will last until medical aid is available, or until a diving doctor advises that it can be ceased.

Stand with us to protect what you love! Project AWARE


Have you ever heard a success story of a diver freeing a turtle, dolphin,  shark or even a whale entangled in fishing nets or other debris?

These life-saving actions never fail to amaze me.

Many of these stories have a happy ending. But sadly, not all of them do. As divers, we're sometimes at the right place at the right time and we can’t help but try to rescue these straggling, innocent creatures.

However, despite these heroic efforts marine life in the thousands are affected by pollution that we produce on a daily basis.

Would you invest in prevention and help Project AWARE stop our trash from needlessly killing marine life?

Last year, the scuba diving community helped Project AWARE:
  • Highlight to world leaders the devastating impacts of marine debris and emphasize the urgent need for solutions at the Our Ocean Conference.
  • Fight to protect threatened sharks and rays and strengthen shark finning bans in the Atlantic and Indian Ocean.
  • Secure a mandate for safe release of manta and devil rays caught in the tuna fisheries of the Eastern Pacific.
We're definitely making a difference, but we've still got a long way to go and we can't do it without the generous support of divers like you.  

We need the full weight of the diver community behind us right now. Can we count on you?

Thank you for doing your part to protect our ocean and marine life for future generations.

 "Last week, Jon M. Piepkorn, Clare Caroline Brown and Stuart Gow showcased the first part of our two-part feature on the eight best places to dive in Fiji. Here they bring you the much anticipated final four:

The islands of Fiji, which I can proudly state have some of the best diving in the world, are one of a kind. To sports enthusiasts, the Pacific nation is rugby sevens; to topside adventurers, it is its unique traditions and heritage; but to divers, Fiji is a vast unchartered underwater haven, teeming with unique forms of marine life that are yet to be explored. Here are the final four:

Divers swim with giants of the deep - Fiji Times Online

DIVERS with KoroSun Dive in Savusavu had the rare good fortune of encountering a whale shark earlier this week on a dive at the famous Dream House site.
The approximately 25 foot long whale shark swam lazily between divers for about 15 minutes.
KoroSun Dive owner and operator Colin Skipper said it was the first time in more than 40 years of diving to see a whale shark.
One of the divers, Amy Savage, said they were headed out of the blue when they spotted a spot in the sea start to turn white.

Fiji Scuba Diving & Snorkeling  Paradise, Fiji Style

DESCEND INTO THE SOFT CORAL CAPITAL OF THE WORLD

Paradise, Fiji style. Long hailed by scuba divers as being the “Soft Coral Capital of the World”, Fiji offers tantalizing diving opportunities that will mesmerize even the most jaded dive traveler.  Straddling the International Date Line, Fiji is comprised of roughly 300 islands and atolls sprinkled across 200,000 square miles of the South Pacific Ocean.  Fiji’s rainbow reefs are renowned for their wonderfully pristine flowery soft corals, large branching fan corals, schooling pelagics, dazzling tropical fish, towering coral bommies, barrier reefs, precipitous drop-offs and offshore pinnacles.  A vast number of these incredibly exotic reefs still remain largely unexplored. When compared to other exotic dive destinations, another of Fiji’s great virtues is that it only takes 12 hours to get there from North America’s West Coast.

The Fiji Siren is back operating and diving in Fiji - DiveNewswire

On the morning of February 20, Fiji encountered the most powerful cyclone in the Pacific nation’s recorded history.
Thanks to the bravery of the captain and crew on board and the following hard work of the Fiji Siren crew and the Siren family ground support, the Fiji Siren is now back in action. Cruises diving the Soft Coral Capital of the World started again on the 14th of April!
Since the cyclone, all the dive shops around Fiji have been checking the reefs in their area and everybody is happy to discover that most of the reefs haven’t been damaged or, if they have, then only suffering minor damage. The feedback from the first trip was kind of great too! Mantas on almost every dive, plenty of sharks, beautiful corals with plenty of macro life and schooling of fish!
• Midway: This area is almost unharmed and the underwater life keeps swimming around the sea fans and hard corals as if nothing has happened: nudibranch, lizard fish, starfish, spotted eagle ray and countless schooling pelagics’ such as blue fin trevally, jacks and barracuda are all still in attendance.
• Vatu I Ra Passage: This area has no damage and you wouldn’t know a massive storm had recently passed by! The soft corals are out en mass, as are the fish life with black tip, white tip and grey reef sharks, huge schools of giant trevally, jacks, unicorn fish and groupers all cruising around.
• Vatu Lacu: The healthy reefs and prolific fish life are everywhere! Lots of sharks, plenty of nudibranch, cheeky blennies, everyone’s favorite Nemo and of course our trademark anthea’s in schools way too big to count.
• Tavenui: Most of the area is just as before! The hard corals, soft corals, giant trevally, whitetip reef sharks, pipefish, nudibranchs, garden eels, schooling fusiliers, unicornfish, schools of fish are in full bloom in all colours of the rainbow!
• Beqa Lagoon: The entire Coral Coast between Nadi and Suva including Pacific Harbour were relatively unaffected by the cyclone. There was only minimal damage and the bull sharks are already missing you!!!!

The Fiji Siren offers affordable luxury liveaboards in Fiji all year round with a choice of 7 or 10 night itineraries, with 4 guided dives per day in small groups. All this surrounded by their professional, experienced and friendly crew.
The vessel features a/c cabins with en-suite facilities and plenty of space for you to relax and enjoy your time onboard, as well as, a dedicated camera set-up and charging station with plenty of additional storage for all your extra lenses, strobes and batteries. It is thoughtful touches such as these that make Siren Fleet the best choice for both professional and amateur photographers. The Fiji Siren offers free essential scuba equipment rental and free Nitrox.
Would you like to support this country of happy and welcoming people, then choose Fiji on board the Fiji Siren! 10% of the value of all Fiji bookings made in April and May 2016 will go to help the people in Fiji, through their campaign with Sea Save to rebuild homes and lives.
