Hurricanes Dean and Felix : Dive resorts in the Caribbean and Central America received pardons as Hurricane Dean in August and Felix in September passed them by with only slight lashings of wind and rain. Costa de Cocos, the Mexican Yucatan resort we profiled in our August issue, also got off easy during Dean. “No structural damage, just a lot of trees down, beach clean up, and some roofs to put back on,” report owners David and Illana Randall. The diving area most affected was Mahajual, 40 miles north of Costa de Cocos. On its Web site, Maya Palms Resort states it suffered moderate damage but gave no details, however this is not a resort we can recommend, damage or not. Read our August travel feature about Costa de Cocos for free at Undercurrent.

Galapagos Islands Update : On August 23, Ecuador’s President, Rafael Correa supported liveaboard owners’ proposals to continue dive trips until December 31 and all Galapagos National Park dive trips through 2007 will operate. The GNP will issue new diving permits for 2008, but local fishermen will be given priority, which may mean fewer Galapagos dive trips. . . .No changes were made to Correa’s lifting of the ban of taking shark fins “caught accidentally.” As we reported in the September issue, hundreds of sharks are now being slaughtered daily. Divers will notice the impact in the GNP, says subscriber Aaron Wiltfong, who dove there last month on the Galapagos Aggressor. “The diving is still world-class and the critters are still there but I am disheartened to see fewer hammers, less jacks and less everything.”

Caribbean Dive Boat Leaves Two Behind : Last month, two British divers were abandoned off Antigua for five hours after dive crew from Sandals Grande Antigua Resort failed to notice they were missing. The two drifted for miles after the boat left the site for lunch without them, and continued to dive elsewhere in the afternoon without noticing. Their disappearance was discovered only when their wives asked for them when the boat arrived back at the dock. Sandals fired four staff but later reportedly reinstated two of them and refused to comment.

Needlefish Stabs Diver to Death : Crikey: A 16-year-old boy died after being stabbed through the heart by a needlefish last week as he was diving for sea cucumber in northern Vietnam’s Halong Bay. Duong Trong Anh was in six feet below the surface when the three-foot needlefish, a type of gar with a long, pointed snout, stuck its bill into his chest then pulled it out. Anh died shortly after. Attacks by needlefish are rare but investigators believe the fish might have been startled by the divers and tried to swim away but accidentally stabbed Anh. Needlefish are common in all waters divers visit and this danger another caution that most of us hadn’t considered.

When Lightning Strikes : In July, diver Stephen Wilson, 36, died from electrocution when a lightning strike hit in his tank after he had resurfaced from a dive near Deerfield Beach, Florida. Potentially, lightning is the biggest weather danger for divers. What precautions should divers take during a storm? Read this article at Undercurrent.

How Much Does Air Cost? The trade journal “Dive Center Business” recently surveyed dive stores about the price they charge for air and Nitrox fills. Compared to the same survey done in 2005, air is now more expensive to breathe. The average charge for a standard air fill is $5.67, compared to $4.97 in 2005, a 12 percent increase. The typical Nitrox fill increased 10 percent, to $11.19 from $10.09. The Southwest typically has the cheapest air fills, averaging $4, while the Southeast has the cheapest Nitrox fills, averaging $10.14. The Rocky Mountain states charge the most for both, averaging $6 and $13.22 respectively.

What You’re Missing in the September Issue :

  • Cayman Aggressor IV, Cayman Islands
  • Land-based recommendations for the Caymans
  • Industrial oxygen in Nitrox
  • The skinny on no-see-ums
  • Sunscreens are short on protection
  • The warmest wetsuit lining?
  • Who to contact for faulty gear
  • Secondary drowning
  • Pacific lionfish now common in the Caribbean
  • And much more

CPR USING ABDOMINAL COMPRESSION?

Filed under: Interesting Newsscubadoc @ 11:12 am
    WEST LAFAYETTE, IN — September 6, 2007 — A biomedical engineer at Purdue University has developed a new method to perform cardiopulmonary resuscitation that promises to be more effective than standard CPR because it increases nourishing blood flow through the heart by 25% over the current method.

    A new technique is desperately needed because conventional CPR has a success rate of 5% to 10%, depending on how fast rescuers are able to respond and how well the procedure is performed. For every one minute of delay, the resuscitation rate decreases by 10%.

    “In other words, at 10 minutes, the resuscitation is absolutely ineffective,” said Leslie Geddes, Showalter Distinguished Professor Emeritus in Purdue’s Weldon School of Biomedical Engineering. “Any medical procedure that had that low a success rate would be abandoned right away. But the alternative is not very good, either: Don’t do CPR and the person is going to die.”

    Geddes has developed the first new CPR alternative, called “only rhythmic abdominal compression,” or OAC-CPR, which works by pushing on the abdomen instead of the chest.

    “There are major problems with standard CPR,” Geddes said. “One is the risk of breaking ribs if you push too hard, but if you don’t push hard you won’t save the person. Another problem is the risk of transferring infection with mouth-to-mouth breathing.”

    The new CPR method eliminates both risks, Geddes said.

    Findings will be detailed in a research paper appearing this month in the American Journal of Emergency Medicine, published by Elsevier Inc. The paper was authored by Geddes and his Purdue colleagues Ann E. Rundell, assistant professor of biomedical engineering, biomedical engineering doctoral student Aaron Lottes, and basic medical sciences graduate students Andre Kemeny and Michael Otlewski.

    In standard chest-compression CPR, which has been in practice since the 1960s, the rescuer pushes on the chest and blows into the subject’s mouth twice for every 30 chest compressions. However, the risk of infection is so grave that many doctors and nurses often refuse to administer mouth-to-mouth resuscitation. In one 1993 study of 433 doctors and 152 nurses, 45% of doctors and 80% of nurses said they would refuse to administer mouth-to-mouth resuscitation on a stranger.

    “This is the real world that nobody knows about, and it’s a sobering thought,” Geddes said.

    OAC-CPR eliminates the need to perform mouth-to-mouth resuscitation.

    The American Heart Association requires that rescuers administering CPR push with enough force to depress the chest 1 and a half to 2 inches at a rate of 100 times per minute.

    “To depress the chest 1.5 to 2 inches takes 100 to 125 pounds of force,” Geddes said. “So you have to push pretty hard and pretty fast, and two people are needed to perform it properly. One blows up the lungs and the other compresses the chest. And when the one who’s compressing the chest gets tired, they change positions.”

    OAC-CPR requires only one rescuer.

    Instead of two breaths for every 30 chest compressions, the new procedure provides a breath for every abdominal compression because pushing on the abdomen depresses the diaphragm toward the head, expelling air from the lungs. The release of force causes inhalation.

    Researchers have known since the 1980s that pushing on the abdomen circulates blood through the heart. The idea was originated by Purdue nursing doctoral student Sandra Ralston, Geddes said.

    “She made the remarkable observation that if you pushed on the abdomen after each chest compression you could double the CPR blood flow,” he said. “So I started thinking, what would happen if you just pushed on the abdomen and eliminated chest compression entirely?”

    The procedure provides a new way to effectively perform “coronary perfusion,” or pumping blood through the heart muscle, which is critical for successful resuscitation because the heart muscle is nourished by oxygenated blood, Geddes said.

    “Unfortunately, in standard chest-compression CPR, blood sometimes flows in the wrong direction, which means the coronary blood flow goes backward, bringing de-oxygenated blood back into the heart muscle,” Geddes said. “This retrograde flow reduces the likelihood of resuscitation.”

    Findings showed that OAC-CPR eliminates this backward flow.

    The Purdue researchers compared coronary artery blood flow during standard chest-compression CPR with the flow resulting from only abdominal compression CPR. Findings showed that using the new method and pushing with the same force recommended for standard CPR provided 25% more blood flow through the heart muscle without retrograde flow in the coronary arteries.

    The researchers followed the standard recommended by the American Heart Association, pushing with 100 pounds of pressure 100 times per minute.

    “With OAC-CPR, you really don’t have to press as hard or as often, but we followed the American Heart Association standard to avoid possible criticism from people who could have said we didn’t observe the standard,” Geddes said.

    Another benefit of OAC-CPR is that it eliminates rib fractures, which are commonly caused by compressing the chest. Rib fractures cause the chest to recoil more slowly, but effective CPR requires that rescuers wait until the chest recoils fully before compressing.

    Geddes created a wooden “pressure applicator” that resembles a scaled-down version of a baseball home plate. It is contoured so that it can be used to compress the abdomen without pushing on the ribs. However, a rescuer could push with the hands to perform the procedure if no applicator were available.

    Abdominal organs contain about 25% of the total blood volume in the body.

    “You can squeeze all of that into the central circulation when you press on the abdomen,” Geddes said.

    Whether the procedure gains widespread acceptance depends on whether other researchers can duplicate the results.

    “In research, you publish data and then the scientific community looks at the data and tries to duplicate it to verify that it works,” said Geddes, who was awarded the National Medal of Technology from President George W. Bush in a White House ceremony on July 27. It is the nation’s highest honor for technological innovation.

    The research was funded by the Purdue Trask Fund.

2007 Historical Diving Society Conference in Tarpon Springs

Filed under: Interesting Newsscubadoc @ 3:32 pm

2007 Historical Diving Society Conference in Tarpon Springs

 

The 2007 Historical Diving Society Conference will return to the famous Greek sponge diving community of Tarpon Springs, Florida, October 26 - 28, 2007. This is the weekend before the DEMA 2007 show in Orlando, Florida. Tarpon Springs is just over an hour from Orlando.

 

The Historical Diving Society has partnered with the City of Tarpon Springs for this year’s conference. The conference will include the Friday evening City Welcoming Reception at the historic Sponge Exchange, full Saturday Conference at Tarpon City City Hall, and the Awards Banquet with Zale Parry at The Westin Innisbrook Golf Resort.  There will also be a traditional Greek sponge diving demonstration on Sunday.

 

Presentations at the conference will include the following:

 

Wooden Tanks and Live Sharks by Zale Parry. Internationally recognized as the pioneer female Hollywood diver, Zale Parry carved here own unique spot in diving history when it was predominantly a “Mans World.” In 1954 she set a new international scuba depth record, and was on the cover of Sports Illustrated in 1955, in what was possibly the first swim suit issue. Her celluloid career includes Sea Hunt, Kingdom of the Sea, Voyage to the Bottom of the Sea, The Aquanauts, and more. Zale will recount her adventures on both sides of the Hollywood underwater camera.

 

The History of Great White Shark Diving by Carl Roessler. From the early Australian adventures to current world operations, carl will recap the history of controlled (and some uncontrolled) encounters with the oceans ultimate predator. carl has 100’s of “in cage” hours filming the Great White Shark. He is a pioneer of diving tourism having operated tour’s to diving’s remotest regions since the 1960’s.

 

Hollywood Underwater by Kent Rockwell. From 20,000 Leagues Under the Sea, Sea Hunt and The Creature >From the Black Lagoon, this is an overview of diving in the movies and on tv. Kent is the associate editor of Historical Diver magazine and a leading authority on scuba history, including the behind the scenes history of tv’s first major diving show, Sea Hunt.

 

The Sponge Divers of Tarpon Springs by Tom Lowe. Tom is head of Eagle Productions and maker of the critically acclaimed PBS documentary on the history of the divers of Tarpon Springs. Tom will lead us on a visual journey back through time, from the birth of  American sponge diving up to the challenges of the modern day sponge diver.

 

The Japanese Divers of California by Scrap Lundy. Internationally recognized as one of the leading authorities on the history of abalone diving, Scraps 1997 book on the subject sold out. In this presentation Scrap will show the development of a diving industry on the opposite coast of America that was also established and developed by immigrants starting in the late 1800’s.

 

Conference tickets are $35.00 each and available now. Tickets for the Awards Banquet, with Zale Parry, $55.00 each and available now. These tickets are limited in number. “Smart Casual” dress is required for the Awards Banquet. You can save $15.00 by purchasing a combined Conference and Banquet ticket for $75.00 prior to September 15, 2007.

 

On Sunday October 28 there is an opportunity to dive traditional Greek Sponge diving gear. This will be a repeat of the 2005 program, when Tarpon City mayor Beverly Billiris made the first dive. The dive will again be made from a traditional sponge boat. There are a very limited number of spots available on a first come, first served basis. For complete information contact Rick Ford at 305-394-1706 or email him at ricklynn@terranova.net.

USAF Hyperbaric Medicine Web Site

Filed under: Interesting Newsscubadoc @ 3:20 pm

We have received the following information that you might find of value:

Hi Ernie:

Don’t know if I sent you a line regarding the changes - but in Feb or March
2007, the USAF put their hyperbaric medicine web site behind a firewall, and
you can only access it if your IP address is a DOT-MIL.  They said it was
because military websites are the target of over 10,000 hacking attempts per
month.  Guess I can’t blame ‘em.

So - - I republished the old version of the Davis Hyperbaric Medicine
Website circa 2002 (they hadn’t updated anything since I retired then,
anyway J  )  on my own servers, and all the oldie but goodie stuff is again
available for review.  It can be found at:
