Scientists Invent Oxygen Particle That If Injected, Allows You To Live Without Breathing

New Medical Discovery

A team of scientists at the Boston Children’s Hospital have invented what is being considered one the greatest medical breakthroughs in recent years. They have designed a microparticle that can be injected into a person’s bloodstream that can quickly oxygenate their blood. This will even work if the ability to breathe has been restricted, or even cut off entirely.

This finding has the potential to save millions of lives every year. The microparticles can keep an object alive for up to 30 min after respiratory failure. This is accomplished through an injection into the patients’ veins. Once injected, the microparticles can oxygenate the blood to near normal levels. This has countless potential uses as it allows life to continue when oxygen is needed but unavailable. For medical personnel, this is just enough time to avoid risking a heart attack or permanent brain injury when oxygen is restricted or cut off to patients.

Dr. John Kheir, who first began the study, works in the Boston Children’s Hospital Department of Cardiology. He found inspiration for the drug in 2006, when he was treating a girl in the ICU who had a severe case of pneumonia. At the time, the girl didn’t have a breathing tube, when at the time she suffered from a pulmonary hemorrhage. This means her lungs had begin to fill up with blood, and she finally went into cardiac arrest. It took doctors about 25 minutes to remove enough blood from her lungs to allow her to breath. Though, the girl’s brain was severely injured due to being deprived of oxygen for that long and she eventually died.

Microparticle Composition

The microparticles used are composed of oxygen gas pocketed in a layer of lipids. A Lipid is a natural molecule that can store energy and act as a part of a cell membrane, they can be made of many things such as wax, vitamins, phospholipids, and in this case fat is the lipid that stores the oxygen.

These microparticles are around two to four micrometers in length and carry about three to four times the oxygen content of our own red blood cells. In the past, researchers had a difficult time succeeding as prior tests caused gas embolism. This meant that the gas molecules would become stuck trying to squeeze through the capillaries. They corrected this issue by packaging them into small deformable particles rather ones where the structure was rigid.

Potential Future Uses

Medical: There is the obvious medical uses where the microparticles can be used to save off death from a restriction in breathing due to inflammation of the lungs, collapsed lungs, and the like. It would be good to have these injections ready in hospitals and ambulances for when the time is needed.

Military: Can you imagine a navy seals capability when they wouldn’t need to surface for air and could stay underwater for over 20 minutes? If a boat was to begin to sink, you could shoot yourself as the boat is going down to ensure you aren’t drowned in the under current of the sinking vessel. How about for toxic gases when a facemask is unavailable. The military could have a number of uses for such a medical advancement.

Private Sector: Really this can be used as a precaution for anything nautical where the potential to drown is a real danger. Deep sea rescue crews could inject themselves prior to making a rescue, underwater welders can use it in case they become stuck or air is lost to their suits. The potential use for anything water related seems extremely worthwhile.

Conclusion

In the end, this is an amazing medical advancement and I cant help but recall the movie the Abyss when they took the pill, their helmets filled with air, and they were told they can breathe the water. Well what if they really couldn’t “breathe” water” but since the urge to breathe is natural, that must take place… even if you’re not breathing air per se. But your body was provided with enough oxygen for a time period by taking a pill. It’s just goes to show that anything, absolutely anything that can be thought up, can potentially one day become reality. Thank you scientists, for reminding me that people and their ingenuity are nothing short of awesome.

Imagine For A Moment… Freediving At Wakatobi

Imagine for a moment…

Putting on your freediving equipment in the shade on the dock. Quick safety briefing between the partners in the group and then perform an equipment check. You make sure your climbing harness is secure and do a last check on your freedive computer for mode and time/depth alarms.

You and your partner grab an underwater scooter as do the other buddy teams. You climb down the ladder into more depth than you’ll use, onto a vertical wall with what seems like unlimited viability. Light rays dance around as the top of the reef is level beside you while you float on the surface breathing up.

You have over 90min of continues burn time on gear four of seven which will last 3hrs with a scooter capable of diving to the depth of a 60 story building and do running speed.

A grand adventure is one inhalation away as you freedive up, down and along a marine preserved wall documenting your experience in almost every direction as you cruise effortlessly and breathlessly.

From 20-23 August 2016 DAN/Rolex Diver Of The Year Kirk Krack and World Champion Freediver Mandy-Rae Krack will be teaching a 4 day Intermediate Freediver Course at the amazing Wakatobi Dive Resort in Indonesia.

You too can join them on a PFI Freediving Expedition that is an ocean gem called Wakatobi.

For more information on the PFI Intermediate Freediver Course and how to book can be found on the Performance Freediving International website. Details on the Wakatobi resort can be found on the Wakatobi website.

Mares Introduce Their New Freediving Line

This year’s big news from Mares is the new FREEDIVING line, designed specifically to greatly improve the performance of freedivers and apneists. A line developed and created using the traditional quality and reliability of Mares, with many new products dedicated specifically to their many apnea enthusiasts.

Within the Freediving line, new wetsuits take first place of importance, stemming from a detailed analysis of the needs of freedivers during their dives. For the first time in the Pure Instinct line, there are wetsuits completely dedicated to women, created with special characteristics distinguished by their cut: shaped to fit the female form and aid movement. This is very important, highlighting the attention paid to the world of FREEDIVING by Mares.

The Apnea Infinity 30 models, available for both men and women, are a one-piece suit with a separate hood and new pre-formed cut: great comfort guaranteed, even in extreme positions requiring maximum arm extension. The Apnea Infinity 30, in fact, provides great freedom of movement due to the new 3mm neoprene, with a smooth outer layer and inner lining. The elastic inner lining and back zip allow for easy donning. The mix of neoprene chosen is highly resistant to compression and also has high thermal qualities. The new production process, allows for the creation of a smooth exterior, increasing elasticity and resistance to abrasion, while reducing friction in the water for better hydrodynamics. Neoprene panels with a high elastic inner lining are present in areas of greater strain, for example the neck, underarm and base of the zip. Much attention has also been paid to the aesthetic aspect of the wetsuit, highlighted by grey side stripes from the ankle to the wrist; lending it a ‘fluid’ look that is enhanced during vertical and horizontal movements in apnea.

The Apnea Instinct 17 is available in both male and female versions, created with the same innovative neoprene as the Apnea Infinity but with a thickness of 1.7mm. It is a two-piece wetsuit with jacket and high-waist pants, developed with a preformed cut and unique white graphics which make it particularly attractive. The male jacket includes a ‘beaver tail’ closure and double quick-release fastening system. The female version utilizes a single fastening closure system. The Apnea Instinct 17 wetsuit is the ideal solution for competitions in pools and very warm waters.

Completing the line of wetsuits dedicated to freediving is the Apnea Instinct 50 model, a 2-piece suit which echoes the preformed cut of the Apnea Instinct 17, but is constructed of 5mm lined black neoprene with an open-cell interior. The mix of neoprene is very elastic and resistant to wear during the most challenging dives. Around the face, wrists, ankles and waist of the pants, the neoprene is 3.5mm in thickness for easy donning. The pants are high-waisted and the closure system on the jacket is in the form of a beaver tail with a double quick-release closure system (single closure for women).

In the new FREEDIVING range there are also some special accessories.

A nose clip specific for apnea, studied down to the finest of details and now finally available to freedivers all over the world. This small accessory is fundamental for all freediving activity and other varied specialties of this sport. The new shape of the nose clip is highly ergonomic and adapted to use with or without a mask; fundamental for carrying out the correct equalization procedure without the need for hands. Its specific design makes it very compact and light, with a high level of detail in the area of contact with the nostrils. This point of contact has a soft mould for greater comfort and better grip on the nose, as well as guarantees better regulation of pressure on the nostrils due to the symmetry of design. The new nose clip is ideal for apnea in all situations including swimming disciplines.

One of the most interesting accessories is represented by the new Apnea Backpack. Mares also wanted to dedicate attention to pre and post dive, where good organization of a kit is fundamental. The Apnea Backpack is designed to allow freedivers to easily pack and transport all of their equipment even when wet, as the bag is watertight. The material used is light and abrasion resistant; the ideal bag for transporting equipment in every situation. The backpack has a large internal volume, 75 liters, which allows for storing long freediving fins including all other necessary pieces of equipment the diver requires. Lastly, the comfortable ergonomic shoulder straps and front pocket for documents make the Apnea Backpack a highly versatile product for all freedivers.

Freedive With Dolphins In The Red Sea On A One-Week Liveaboard Trip This October

Live in the U.K. and jonesing for a freediving trip to the Red Sea and swimming with dolphins? The folks at Freedive-Earth.com might have just the ticket for you this coming October.

Freedive-Earth.com is offering a one-week trip to Hurghada, Egypt where you’ll board the liveaboard Aquastara and sail on it from Saturday, October 1 to Friday, October 7.

You’d be flying out of Gatwick Airport and upon landing in Hurghada would be driven to the Aquastara. The vessel will spend the next six days moored at different places near the 10-km/6.2-mile-long Sataya Reef, which is home to a pod of about 50 spinner dolphins that tend to swim by each day at dawn and dusk.

In addition to the dolphins, you’d also have the chance to see turtles, Eagle and Manta Rays, sharks and a Napoleon Wrass or two. According to Freedive-Earth.com:

“The dolphins are used to human interaction and will most likely allow you to join their pod. being moored at Sataya reef overnight also gives an opportunity to spend time with them without other tour boats being a round. This provides a very personal interaction with them.”

You’ll also have the chance to take freediving courses down to a depth of 40 meters/131 feet, scuba courses (as well as regular scuba diving), daily yoga classes, photography workshops, line fishing and more.

Buffet breakfasts, lunches and dinners (with vegetarian/vegan options) and soft drinks are part of the package.

The final night will be spent at an area hotel, which will include the chance to go souvenir shopping in Hurghada, followed by an afternoon return flight to Gatwick.

The whole trip — round-trip airfare from Gatwick included — will run you approximately £1,200/US$1,737/1,533 Euros.

You’ll need to put down a £150/$217/192 Euro deposit when you book your trip with the full balance required by July 31. They’re also offering a possible installment plan.

Freediver explains addictive pleasure and pain that drives him to plunge

FREEDIVING has been around for thousands of years but as a sport it’s a relative newcomer. Divers compete by packing their lungs with air, holding their breath and plunging to the bottom of the ocean for minutes at a time.

With no oxygen and often no fins, they are lured to extreme depths of inky blackness and empty silence. Pressure builds on their chest, eardrums and sinuses. Their heart slows, nitrogen can affect their thinking and there’s a chance they may black out.

At a certain point, they no longer need to swim. They simply sink under the weight of the water.

Freedivers push the limits, never knowing how far – or how deep – they can go on a single breath. It’s a journey of self-discovery.

Cairns freediver and self-confessed dive junkie Rob Berto has felt the pain and pleasure of pushing himself into the deepest zones and has just returned from The Bahamas where he was part of a hand-picked safety crew at the world’s most prestigious freediving event, Vertical Blue.

Held at Dean’s Blue Hole, the world’s deepest saltwater sinkhole, the competition’s home is a lagoon which drops dramatically to 202m a few sandy steps from the beach.

It was Rob’s second trip to Vertical Blue, where he was the only Aussie safety diver and saw 24 athletes from 15 countries smash 34 national and three world freediving records.

The high point was Kiwi freediver William Trubridge’s astonishing performance.

“He bettered his own world record twice,” says Rob, who was Trubridge’s safety wingman for the second dive – 124m in four minutes and 34 seconds.

“I was witnessing history in the making and had the best seat in the house,” he says.

Rob, 29, pushed a few boundaries himself on the Caribbean island of Roatan, hitting a personal best of 76m in the discipline of free immersion (pulling on a rope to descend and ascend) and 61m without fins.

“The feeling of satisfaction is one I will never forget,” he says.

The manager of DiversWorld in Cairns has spent most of his working life around the sea – skippering boats, diving commercially and guiding spearfishing adventures.

“My first job out of school was as a diving instructor, but the work dried up in winter in Melbourne, so I followed my best friend to Cairns and started a career here. It’s pretty much the best place in Australia if you want to work as a diver or in the industry.”

He got his start teaching tourists how to scuba dive and breathe underwater, but developed an interest in freediving when he took up spear fishing.

“Spearfishing is a way of underwater hunting – a means of catching our dinner, so we don’t use any breathing apparatus. It’s only breath hold. It’s a lot fairer for the fish because it’s man directly against the fish.”

His first freedives were quite short but his mind, body and lungs can now cope with up to five minutes without air.

“Like most things, it’s repetition. They’re all muscles you’re training. We are diving mammals. We’re equipped the same as a whale or a dolphin, so it’s basically getting back to our roots and relaxing the mind and being comfortable in a watery environment.”

Rob has a daily routine of stretching, yoga, relaxation and warm-up dives before heading into his target dive of the day.

“Every day is an ongoing quest to be better and more like a fish, at one with the water.

“For me the dive is a spiritual experience. The only thoughts are positive and relaxation is key. If you’re not relaxed, your muscles won’t allow the pressure to take place on them – especially your lungs – and you won’t be able to equalise at depths.”

Rob says Cairns has become a hub for freedivers, with the Great Barrier Reef on one side and the deep waters of Lake Eacham on the other. “At Lake Eacham we have over 60m available to dive and it’s a great training platform for beginner and advanced freedivers, so people travel from around Australia because they know they’re going to have flat water and the depth available 365 days a year.”

He says freediving has more to do with mind control than age, weight, strength or lung capacity.

“With proper training, you can progress quite quickly. We’ve seen people go from beginners … to world record holders.”

And safety is paramount.

“You’re entering another environment, so you need to be respectful, but if you follow all the protocols, it’s very safe.”

Increasingly popular, no one understands the pull of freediving more than him.

“It’s addictive. It’s the challenge – of everything – the body, the mind. From the moment I wake, it captures how I live my life.”

Freediving The Caves Of Kefalonia

Kefalonia, the largest of the Ionian Islands has typical Greek rocky coastline with crystal clear water – a perfect late summer freediving holiday destination. It also boasts 17 caves in one area 5 of which contain lakes, albeit with various degrees of accessibility or suitability for swimming.

the-caves-of-kefalonia-1

Kiri and I dived several untouched beaches and were pleasantly surprised to find a few rare giant mussels, Pinna Nobilis, (found only in the Mediterranean Sea). It is one of the largest bivalves in the world, growing to 120cm long.

the-caves-of-kefalonia-2

After some scenic coastal dives we met up with Aquatic World, a friendly shop on the islands east coast, who provided us some local geographical information and kindly lent us some lead!

the-caves-of-kefalonia-3

We told them that NoTanx specialized in underground lake diving (Phreatic Divers), and that we were interested in the islands hidden, secret labyrinth of phreatic tunnels. Water is sucked into huge sink holes from the Ionian Sea on the west side of the island, via huge karst conduits and expelled in the Bay of Sami on the east of the island. Although just 10miles on land this journey takes the water over 2 weeks to filter through these huge underground systems.

phreatic (adj) relating to or denoting underground water in the zone of saturation (beneath the water table)

They pointed us in the direction of several of the cenotes pits that have resulted from the collapse of the limestone bedrock, exposing the water beneath, very similar to those found in the Yucatán peninsula of Mexico. Here is what we uncovered…

Melissani Cave

Melissani cave is one of these cenotes, it was discovered after a collapsed during the 1953 Ionian Earthquake. Tourists can take a short trip by paddle boat through both sections of the lake; one open to the sunlight, the other dark and mysterious despite the incandescent floodlight flickering behind a mound of fallen roof rubble.

As it is a famous tourist site; diving is forbidden. Despite this, we persevered and managed to arrange a meeting with the Mayor of Kefalonia, who, after some negotiating, gave us permission to freedive in exchange for photographs.

the-caves-of-kefalonia-4

Returning to the cave, the crystal turquoise of the water almost takes your breath away, as does the 14°c / 57°f water temperature. The sudden change in temperature forms a permanent mist below the surface of the water at about 8meters.

The chamber drops off quickly to 30m with water so clear it feels like flying. The visibility is stunning, we could almost see the entire length of the 50m long 1st chamber!

the-caves-of-kefalonia-5

The splendor of the main chamber is awe-inspiring: thousands of years ago the cave was dry, leaving huge speleothems (stalactites & stalagmites). Surprisingly, there is very little life in the water considering the amount of sunlight falling on the open section. Eels, however, seem to thrive there, and are not afraid of divers.

Relaxation, Recovery Breathing & Daily Breath Holds?

Last week we learned about Controlling The Chemical Axis Of Breathing from renowned breathing expert Dr Peter Litchfield. If you happened to miss the equation that explains optimal breathing as defined by the “chemical axis,” why hyperventilation is so bad and how our reflexes get in the way of proper breathing habits, click here to listen to that episode first so you have a good understanding of what you are about to hear this week.

Putting It To Work For You

In part 3, Peter puts all the information from the previous episodes together to give you actionable tips on how to make important changes in your own life. Listen to the interview above to learn, how to relax during a dive, the proper approach to recovery breathing and why holding your breath might be good for you!

Dr Litchfield talks about how to relax during a dive by finding something in your day-to-day life that will trigger a thought process which moves you from sympathetic (fight or flight response) to parasympathetic (a ‘rest-and-digest” or “feed and breed’ state of mind). This is especially key for freedivers who need to keep their heart rate low and their awareness sharp to control the dive properly. This relaxed state of mind can be achieved in a variety of ways, but everyone responds to different methods. If you are having trouble finding something from your every day experiences, try something like yoga, which has worked for many world class freedivers around the world.

Trusting Your Body

Most freedivers know that recovery breathing is an important part of the dive. However, some may not be aware that the best technique is to simply allow your body to naturally return your breathing to normal. Peter suggests relying on your own reflexes because the body can self-regulate. You will breath off the CO2 and the system will adjust itself without fancy techniques or assistance in most cases.

The secret is to rest and focus on your breathing spectator’s perspective, from a third person point of view if you will, to get what he calls breath awareness. Avoid the urge to “control” your breathing and allow the reflex to do its job. If you alter the recovery process, by trying to breath harder for example, you run the risk of developing bad habits in other areas of your life and cause dysfunctional breathing.

People who hold their breath every day normally don’t experience oxygen deficit. If anything, holding your breath can restore good carbon dioxide levels (CO2). Incidentally, the best way to check is to use a capnometer to check how quickly the CO2 level restores itself. Keep your head and fight the urge to hyperventilate to avoid headaches or nausea that may keep you from enjoying the next dive.

We aren’t breathing experts like Dr Litchfield, but we do know a thing or two about freediving and hitting your personal goals. If you have a question about anything we’ve discussed or just freediving in general, let us know in the comments section below. We’ll be sure to respond and maybe even get Peter to do a follow up interview if you need some further clarification!

[AUDIO] Alexey Molchanov: The Secret To Success… ? It’s Just Like Brushing Your Teeth

45 times national record holder and 4 times world record holder Alexey Molchanov started his freediving career young. At the age of 5 he was diving for sea shells and mussles in the Black Sea in Russia, growing up he was a competitive finswimmer, and at the age of just 17 he broke a national record in his first ever pool competition with a dynamic distance of 158m, after his mum (Natalia Molchanova) read about the sport in a magazine.

These are huge achievements for a freediver who today is still just 27 years old and by all observations has a promising career in front of him. As he says himself, “I was always 100% sure that I made the right choice and every year I’m happier and happier with it.” So what is his secret to this success? And what motivates him to keep trying for it?

“For me just the process of training I enjoy a lot. If I don’t train I feel like my mood is just going down. I like to train because it makes me feel good… it’s just nice when you put a lot of effort into training and in the end you get a nice result as confirmation that your training process was right… I think it’s something that comes from childhood…if you like to train and you like the process then you can’t stop… I like it just as a process, like you wake up in the morning and go and brush your teeth”.

Going Deep

Despite starting off in the pool, Alexey is now most known for his open water dives, holding the world record for constant weight with a depth of -128m:

“ depth is more challenging, it’s a much more complicated discipline than pool. I like to dive deep, so just that gives me joy to train and to compete…. I don’t think that I want to be a champion or anything, I just feel that I have this ability to dive deep so I just follow it and I enjoy it.

If you want to get a good result in freediving you need to be persistent…This is more important than talent.”

Learning To Explore

Alexey’s passion for the sport and the results he achieves are certainly inspiring. He admits that learning to freedive benefits people in endless ways, even those who don’t feel passionate about the water, and even those who can’t swim! But what is the most important thing he has learned from freediving? And what can others learn themselves by taking up the sport?

“When you spend so much time practicing relaxation and trying to swim more efficiently… you learn to be relaxed in any circumstances, like in depth diving, so it really helps in everyday life… being calm, being relaxed. So I think freediving gives this quality, not only to me but to a lot of people.”

“[For others] they would be able to swim and dive whenever they want to and be comfortable in the water….they could just dive and check for corals and sea animals and just being able to explore water: oceans, seas, rivers, lakes, anything. It’s a really useful skill to have and a really nice skill to have… Some, even if they’re not so passionate about water, they just come to learn freediving as a survival skill which is useful to have… We’ve had people who didn’t know how to swim even, learn freediving to overcome their fears”.

We want to share that experience with you! Or maybe you can share your experience with us Either way, write us a comment below and tell us what freediving means to you or why you are interested in this amazing underwater experience.
