There are all kind of BCDs. This is a nice article I found: http://www.divers-supply.com/BCD-Buying-Guide-C395.aspx A Buoyancy Control Device (BCD) or Buoyancy Compensator (BC) is an important piece of equipment that scuba divers wear. It has quite a few jobs to do for you! • It provides positive buoyancy while resting on the surface. • It contains an inflatable air bladder which you can add or subtract air from, allowing you to achieve neutral buoyancy in the water. • It allows the dive cylinder(s) to attach to the BCD • It allows the diver to carry or attach all of their accessories using built-in pockets and D-Rings. You can roughly break the different types of BCD's on the market down to 5 styles; Jacket-Style, Back Inflation, Back Plate and Wing, Side Mount Systems and Hybrid. Each style has positives and negatives, some are better suited to a particular type of diving but they all can be and are used by newer divers as well as the most experienced divers and instructors! Jacket Style BCD [caption id="attachment_2003" align="aligncenter" width="193"] Normal scuba bcd[/caption] The jacket-style is perhaps the most common type of BCD among divers for the last 30 years. The BCD consists of a wearable sleeveless jacket into which an air bladder is integrated that wraps around the diver. The types and configurations of this kind of BCD are numerous, but the basic premise remains that the bladder wraps around and inflates both in front, on the sides and behind the diver. The jacket-style BCD is very comfortable and provides pockets for storage and is commonly found with pouches for weight integration which replaces the need for a independent weight belt. Jacket BCDs are extremely stable in all positions in the water and is the most popular choice for recreational divers all over the world. Back Inflate Style BCD The back inflate BCD only has an air bladder on the back, leaving the diver’s chest area uncluttered. Back inflate BCD’s are known for how great they are at positioning the diver in the more flat horizontal position in the water. Most divers strive for good horizontal positioning (trim). Being in a nice horizontal position is very streamlined with the diver having less resistance moving in the water while swimming; this reduces workload and helps to prolong your air supply. Like the majority of modern BCD's today they are virtually all weight integrated, eliminating the need for a cumbersome weight belt. Some divers when used to diving in a traditional jacket style BCD find the transition to a back inflate BCD a little "different" when on the surface or vertical, however this feeling soon passes and the stability in the horizontal position while diving is truly appreciated! Hybrid Style BCD The hybrid is described as "the best of both worlds" in terms of recreational BCD design. The innovative hybrid air bladder design allows less front clutter than most jackets style units and the flat horizontal diving position you get from a back inflated BCD. However, the unique design allows you a more relaxed and comfortable vertical orientation when you find yourself in that position (kneeling on the bottom or on the surface). This style of BCD is a staff favorite among our Instructors here at Divers Supply. Back Plate and Wing Style BCD [caption id="attachment_2004" align="aligncenter" width="225"] scuba diving wings[/caption] The back plate and wing BCD is considered by many the most versatile of BCD’s There are unlimited possible combinations in backplate choice, wing size and design choice and harness design and harness hardware choices when putting together a back plate and wing system. Most divers who choose this style will assemble to meet their specific needs, often with their instructor or mentor. The Backplate and Wing system is a great choice for divers who are contemplating moving into more advanced diving such as technical deep, penetration wrecks or cave diving. Some of our staff are huge fans of the Backplate and Wing system and would love the opportunity to show you one! Sidemount [caption id="attachment_2001" align="aligncenter" width="225"] Sidemount harnas[/caption] Sidemount systems allow you to dive with your tanks under your arms at your sides instead of positioned on your back. This style of BCD has evolved from Cave Diving in very tight areas to being a popular choice for many technical divers looking to move away from heavy double tanks on their back. It is growing in popularity and we would love to explain the ins and outs of this growing type of BCD! IDC Dive Resort Oceans 5 Dive offers sidemount specialty courses and sidemount instructor specialty courses. Oceans 5 has Hollis 50 sidemount systems with Apeks sidemount regulator sets.
Here around the Gili Islands the customers are mostly diving in a 3mm shorty wetsuit. But it is good to have your own one. Here a nice article about wetsuits: The metric unit used to measure wetsuit thickness. A 3mm Wetsuit would mean the wetsuit rubber measures 3mm thick in all areas of the wetsuit. Wetsuit Thickness (or "Density): The density or thickness in millimeters, of the rubber in a wetsuit. The thicker the rubber, the warmer the wetsuit. Wetsuits usually have two density numbers (for example: 3/2mm) The first number (3mm) refers to the "core body" thickness of the wetsuit that covers your chest, stomach and back. The second number (2mm) is the thickness of the rubber that is covering your extremities like your legs and arms. Example: A 3/2mm fullsuit would mean: 3mm neoprene rubber on the chest, stomach, and back and 2mm rubber on the arms and legs. Wetsuits are constructed in multi-densities for several reasons. 1. Your body will stay warmer for a longer time with your "core" (chest, back) insulated in thicker rubber. Also, in most watersports, your core does not move as much as your arms and legs, so thicker rubber in the torso area is not noticed. 2. Your extremities (arms and legs) do not need to be as insulated as your core. Plus, most watersports tend to require flexibility in your arms, legs and neck. Therefore, the rubber in these areas is often thinner and, as a result, more flexible. Essentially, you are giving up a little bit of warmth in favor of flexibilty and ease of movement. (All things being equal, the thinner the rubber, the more flexible and pliable it is on a wetsuit). Wetsuit Seams: Seam construction is an important factor in selecting a wetsuit. Cold water temps (under 13 degrees Celsius) need sealed seams to keep in the warm water your body is heating and the cold water out of the suit. Currently there are 3 major types of seams available on wetsuits, flatlock, glued and blind-stitched, and glued, blind-stitched and taped. There are many types of wetsuit seams: Flatlock Stitching: Recommended for warm water above 13 degrees. The fabric is layered where the seam meets and stitched completely through to form the seam. This seam looks like railroad tracks. The interior seam construction is flat on both sides. Some water may seep in through these seams. Glued and Blind-stitched: Also referred to as GBS (Short for Glued and Blind-stitched). Recommended for cold water 13 degrees and up. This construction is best for cold water because the seams are glued, then stitched. It looks similar to Flatlock stitching, but is narrower in width. Very little water will seep through these seams. Sealed & Taped: (Glued Blindstitched & Taped) Recommended for very cold water 13 degrees Celsius and below. Same construction as above plus interior seam taping. Tape can be fabric tape, rubber "liquid tape", or neoprene tape. The tape reinforces seams for added durability, and prevents any water from seeping through. These features are commonly found on very cold water suits and most high end suits. Water Temperature Range: The suggested water comfort range that the wetsuit is used in. This is a general guideline only. Many factors need to be taken into account when selecting a wetsuit for specific conditions. Some include: wind-chill, length of use, water temp, air temp, type of activity (kitesurfing, jet skiing, surfing, kayaking, etc.) If you are unsure, always go a little thicker on the gear. It is always better to be a little warm, than cold! Different activities have vastly different effects on how warm you stay for how long. With surfing for example, it is a very aerobic activity, so your body will stay warmer longer than an activity like scuba diving which you are completely submerged and not moving very fast. Wetsuit Neoprene: The rubber product used in wetsuits. Wetsuit neoprene is laminated in hundreds of styles and fabrics. It is very easy to be confused by the selection available to the consumer. However, there are really only a few things you need to know. Wetsuit neoprene can be broken down into a few categories. 1.Standard Neoprene: This neoprene features nylon fabric on both sides with rubber sandwiched in the middle. Standard neoprene is the least expensive neoprene and offers minimal stretch. Entry level suits can be 70-100% standard neoprene. The benefit of standard neoprene is that it is very durable and does not break down as fast as super stretch neoprene. 2."Skin" Neoprene: You can instantly determine mesh skin neoprene by its "rubber" like appearance. Skin neoprene has Nylon laminated to one side of the rubber only. The other side is the exposed rubber. Skin is extremely warm because it doesn't hold water like Nylon fabric. The Nylon fabric that regular neoprene is laminated with holds water it cools and evaporates while you are wearing it. This is called evaporative cooling. Because rubber skin does not hold water on the outside, there is no evaporative cooling on your skin. Plus, skin neoprene is wind chill proof. Wind cannot penetrate the rubber surface. This makes skin very warm. The downside to skin is its durability and flexibility. Even the best skin is not nearly as stretchy as superstretch nylon neoprene. And because it is exposed rubber on the outside, it is vulnerable to rips, tears and punctures. Skin is used mainly in the "core" torso area of wetsuits like chest and back panels. Skin is used in the torso because it aids in keeping your "core" warm during extended sessions. In addition, some cold water gloves, hoods and boots are made from skin because they are so warm and beneficial in cold water and cold wind-chill causing air. Skin can be regular, superstretch, or speed skin. Speed Skin is very smooth skin used on all triathlon wetsuits. 3.Stretch Neoprene: Superstretch neoprene is the most flexible neoprene available. Suits made from superstretch neoprene offer incredible flexibility and minimial resistance while moving. They fit extremely well because they stretch to fit each persons unique body shape. An added benefit is superstretch wetsuits are also extremely easy to get in and out of. Many wetsuits feature superstretch panels designed to offer freedom of movement when in use. Superstretch panels are used under the arms, on the shoulders and around the neck of most surfing wetsuits. This enables the wearer to paddle and move without resistance while paddling. Wetsuit Stretch: Superstretch suits come in many different types so the easiest way to classify them is by the percentage of superstretch rubber used in the construction of the wetsuit. The superstretch is placed strategically for maximum flexibility, usually in the underarms, shoulders, knees, crotch, back and thighs. Simply put, the more stretch in a wetsuit, usually, the more it costs on the rack. To keep prices down on certain lower to mid-range priced models, wetsuit manufacturers use combinations of standard and superstretch neoprene.
The dive computer is the biggest technological advance in scuba diving since the invention of the demand regulator. [caption id="attachment_2014" align="aligncenter" width="140"] dive computer Gili Islands[/caption] Diving computers let you go deeper and/or stay longer and still stay within safe diving limits, by monitoring your depths and times and calculating the nitrogen in your blood on the fly. Doing it on paper assumes a profile of descent to a certain depth, bottom time at that depth, then ascent; scuba computers allow for the near constant change in depth that happens during a real dive. Things to Consider When Buying a Scuba Diving Computer Buttons Are the buttons easy to use even with dive gloves on? Display Visibility Can you read the display even in a low light situation. Are the numbers big enough? Does the background light up if needed? The key numbers you need to be able to see are Depth and Available Bottom Time Remaining. Everything else is a matter of preference. The more information you want to see, the smaller it will need to be to fit on the screen. Display Information Scuba diving computers can display a lot of information. Some things you may see are: Current Depth Max Depth Bottom Time Remaining Ascent Rate Monitors Surface Interval Time No Deco Time Limits For Next Dive Water Temp And any other information you might ever possibly want to know. You need to decide what information is important to you and buy a dive computer that displays that info. Power On and Off Some diving computers begin to record the dive automatically and continue to run for hours after the last dive. Some need to be turned on. Are you the forgetful type or not? Air or Nitrox Do you dive mixed gas now or plan to in the future? If so you need to buy a dive computer that lets you set the oxygen percentage. You can still use these computers to dive air just set the oxygen % to 21. If you don't plan on diving mixed gas you can save money and buy an air only scuba computer. Aggressive or conservative An aggressive computer lets you stay down longer than a conservative one. Some diving computers will be aggressive shallow and conservative deep or vice versa. Some computers will let you adjust this. Research the scuba diving computer before hand and pick one that you are comfortable with. Altitude Does it adjust automatically, manually or at all for diving at altitude. Air-integrated or Stand alone An air integrated computer will monitor tank pressure and calculate air and bottom time remaining. You can get models that either plug into a hose or even do this wirelessly. Stand alone computers don't record this info and you'll need to use a separate pressure gauge. Batteries Can you change the batteries yourself or do you need to take it to the shop or even send it back to the manufacturer? Memory How many dives will it record? Does it only record the last dive or does it record multiple (usually 10). If it only records the last dive you'll have to write the info down in between dives if you want to do a second. Does the memory wipe when you turn the power off? Will the dive computer retain that info if the batteries fail? Downloadable Can you download the recorded dive to your laptop or desktop computer? Do you have to buy a separate software package or hardware (usb cord or other cable) to do so or does it come with everything? Warranty/Service What type of warranty does it have? Can you get it serviced locally or will you have to send it to the manufacturer? There's obviously a lot to consider when looking at buying a scuba dive computer. Make a list of what you want/need and start reading reviews and manufacturers material until you find one that fits. The more options it has, usually the more expensive it'll be. If you want a Nitrox compatible, wirelessly air integrated, expanded memory, satellite link up, gps, does everything for you except make the actual dive and it could probably do that remotely too, you're going to pay for it. The more bare bones it is the cheaper it'll be. Remember no matter how much you pay or how good your dive computer is, it's still just a tool. Like all tools if it isn't used right it can get you hurt. Don't ignore common sense and your own intuition just because your computer is telling you everything is cool. Make sure you practice doing paper dives or even check your computers recorded dive by doing it with a table yourself every now and then just to stay sharp and keep your skills up. And don't forget to "Plan your dive and dive your plan!"
Certain Sea Turtle species are breath holding champions! In regards to the structure of their respiratory system, sea turtles may more closely resemble marine mammals than they do other reptiles. Sea Turtles have the highest oxygen consumption rate of any reptile. Sea Turtles store high amounts of oxygen in blood and muscle tissue. Adult Leatherback Sea Turtles can dive deeply, holding their breath for up to 70 minutes. Loggerhead Sea Turtles have been known to survive for hours under anoxic (lacking oxygen) conditions, such an adaptation may assist in overwintering and hibernation activities. Sea Turtles appear to be extremely efficient at buffering the carbon dioxide in their blood, minimizing the effect of CO2 building up within their body system. A sea turtle's lung provides more area for gas exchange then other reptiles. All Sea Turtles have multi-chambered lungs full of spongy and elastic tissue providing large amounts of surface area for oxygen and carbon dioxide exchange; this allows sea turtles to exchange oxygen at a faster rate than any other reptile. Sea Turtles also have a strongly reinforced airway which is thought to help prevent airway collapse from the increased pressures encountered during deep diving. Sea turtles breathe by moving their pectoral and pelvic muscles (think of flapping your arms and legs), which compresses the area containing the lungs and changes the pressure within the lung cavity allowing both inhalation and exhalation to occur. Shallow diving, air-breathing organisms usually inhale before a dive and store most of the oxygen for that dive within their lungs. In contrast, the leatherback sea turtle is adapted to store much more of the oxygen it needs for deep diving within its blood and other tissues. This has the advantages of making oxygen more quickly available to the body cells and keeping it available even after lung collapse associated with a deep dive would normally have cut off those oxygen stores. All of this you learn during the Sea Turtle Awareness specialty. for more information: email@example.com

Padi Instructor Development Course (IDC) starts 20 October 2013. If you like to chance your life style, if you like the have the ocean as your office this is the way to go. Follow your dreams and become a professional PADI Dive Instructor with an IDC on the Gili Islands! Oceans 5 is a Padi 5 star Instructor Development (IDC) dive resort located on Gili Air. Gili Air is part of the famous Gili Islands, North West Lombok. The diving around the islands offers diving for everyone. If you like big fish (sharks, bumpheads, trevallies, etc), small stuff (nudis, seahorses, pipefish) or turtles. It is a perfect place to start your IDC. The island is not that busy as Bali or Gili Trawangan, but has enough bars and restaurants to have in the evening a nice drink or dinner. The Instructor Development Course (IDC) is a 10-12 day program that enables Divemasters and leaders from other training organizations to achieve their dream of teaching scuba diving using the PADI system. The IE will be held on the Gili Islands. During the IDC you will use the latest teaching techniques, the complete system of PADI support materials, and will be continuously assessed on your teaching and presentation skills. PADI Course Director Camille Lemmens, Padi Course Director Sander Buis and our team of IDC Staff Instructors are committed to your success at the Instructor examination (IE). They also want to make sure that you are comfortable with teaching afterwards. The Instructor program at Oceans 5 Dive Resort exceeds the minimum required by PADI in terms of time and number of presentations you will prepare. The program is taught in a dedicated classroom, the confined water sessions are held in a 25 meter swimming pool and the open water sessions are only 5 minutes away from the dive shop. Our facilities will enable you to study and prepare in a relaxed and chilled atmosphere. Gili Air is so relaxed because there are no motorbikes, no cars and no dogs on the island. Before the IDC there is an IDC preparation. Normally this takes 3-4 days, but it is no problem if you come earlier. During these days your diving skills and dive theory will be brushed. Also after the IDC it is possible to assist instructors on courses so you will get the feeling how a course will be conducted. Maximum of students of an IDC is 8 candidates. The average of 2012 was 4-5 students each IDC. Oceans 5 dive resort has a 100% passing rate of the IE. All the candidates of Oceans 5 dive resort found a job in the dive industry. Mostly they found a job on the Gili Islands, not long after they passed their IE. After the IE there is a possibility to do a prep MSDT program. Oceans 5 offers a lot of instructor specialties, but the most popular ones are Nitrox, Deep, Digital Underwater Photography, Oxygen Provider, Night, and Sidemounting. But there are others you can choose of. It depends about how many dives you have to do for each specialty yo choose how long the prep MSDT takes. Why is Oceans 5 dive resort different than all the other IDC centers?
- Oceans 5 dive resort has 2 course directors.
- Oceans 5 dive resort is well aware of his environment.
- Oceans 5 dive resort organizes every week reef and beach clean ups in the harbor of Gili Air.
- Oceans 5 dive resort has a turtle nursery for injured turtles. With an In -The-House marine biologist Oceans 5 likes to bring some knowledge to the IDC candidates.
- Oceans 5 dive resort offers during the IDC a free marine biology class.
- Oceans 5dive resort is also the only Padi dive center in Asia that is awarded with the Padi Accessibility Award, that means that Oceans 5 can teach and has the possibilities to teach or guide disabled divers.
What do a Nemo, Shark, and a Bumphead Parrot Fish all have in common? You've see them through a mask. One of the most important pieces of diving gear, a mask must be equalized, defogged, and fit properly. In other words, there is more to scuba masks than meets the eye. Masks are important and for everyone a mask should be comfortable fitting. Not being an extra stress factor Underwater. Especially around the Gili Islands because the Gili Islands are part of the famous Coral Triangle. 1. What Is a Scuba Mask?: Scuba masks are different from other kinds of masks. Created specifically for scuba diving, they are made of high quality materials like tempered glass and silicon, materials tough enough to withstand the underwater environment. Snorkeling masks and other masks designed for surface water sports may be made of inferior materials, such as plastic lenses that can fog and scratch easily. Such weak materials could break during a dive. Although scuba masks may work well for snorkeling and other water sports, masks created for surface water sports generally do not work well for diving. 2. Divers Can Not See Underwater Without a Scuba Mask: A mask helps to keep water out of a diver's nose, which is nice. However, the primary purpose of a scuba mask is to allow a diver to clearly focus his eyes. A diver can breathe and swim underwater without a mask (student divers practice this in a scuba certification course). However, he can not see well enough to read a pressure gauge or clearly distinguish hand signals without one. 3. Swim Goggles Can Not Be Used For Scuba Diving: A scuba mask must enclose a diver's nose. This feature increases a diver's comfort by allowing him to empty water from a leaky mask and preventing him from getting water up his nose. However, the reason it is absolutely essential that a mask covers a diver's nose is that it enables the diver to equalize the air pressure in the scuba mask as he descends. This prevents the mask from painfully suctioning on to the diver's face, and in an extreme case, sucking his eyeballs out. 4. A Mask Is a Mask, Right?: Wrong. Many different styles of scuba masks are available to recreational divers. Purge valves, optical lenses, and side windows may be useful or annoying to a diver. It is important to understand the different kinds of scuba masks, and to have a clear idea of what type of mask you want before making a purchase. 5. Not All Scuba Masks Fit all People: Many new divers do not realize that scuba masks need to be fit. People have different head and face shapes, so it makes sense that fit is important. No matter what the price or aesthetic value of a mask, do not buy a mask if it does not fit correctly. An improperly fitting mask can leak or press uncomfortably on a diver's face. For this reason, it is important to determine a mask's fit before purchasing. 6. All Scuba Masks Fog Up, But There Are Ways to Prevent Fogging: Experienced divers know that a foggy scuba mask can ruin a dive. Not only does a foggy mask block a diver's view of the incredible underwater world, but it impedes communication and can be disorienting. All masks will fog up if not treated correctly. Any foggy mask can be fixed. For more Information http://www.oceans5dive.com
Drift diving Gili Islands. Drift diving around the Gili Islands. The Gili Islands are famous for their turtles, Hawksbill and Green Sea turtles. But the Gili Islands are also famous for their currents. Perfect places for a nice drift dive are Halik Reef, Shark Point and Soraya. But have you ever experienced a drift? This amazing kind of dives where you are taken by the currents and allowing you to feel that magical sense of ‘flying’ underwater, while making the dive cover a lot more distance than a standard dive, passing by big and small fishes, and literally flying over reefs! The greater distance over a shorter period of time can be benefit to cover more ground, see a reef on it's full, but on the other hand there is chances of missing out on the interaction and observation of marine life and scoping out the area in more detail. Currents are a continuous directed movement of water generated by forces on the water like wind, the Coriolis Effect and breaking waves. Other factors for the cause of currents is the temperature, salinity and cabbeling of the water itself, but the greatest cause of a current is the tide, which is caused by the gravitational pull of the Moon and the Sun. The Gili Islands have stronger currents in the months: July, August, December and January. The best time to dive for beginners is at ‘high slack’ tide. At this stage there is little or no current to be seen or felt. If you are opting for a drift dive you are depending on the current to be there. Don’t forget to research the water conditions and patterns of the area you wish to dive to allow yourself the best chance of an amazing drift dive. Although drift diving can be known as the ‘lazy’ man's type of diving, it is not to be undertook lightly. Drift diving does require a level of training with specialty courses specifically there to teach you in drift diving. As you do your Advanced Open Water Course you can pick some specialties as part of the course, one of them being drift diving. If that doesn’t satisfy you, there is also a specialty course dedicated to drift diving, and once completed you will be qualified as a Drift Diver. This course requires you to do 4 Drift Dives and complete the training manual with a qualified Specialty Instructor. As with the uniqueness of this type of diving, Drift Divers need to be careful about buoyancy and safety measures, like the surface markers bouys.
The Gili Islands are famous for their turtles! Every dive there is a change to see one of these amazing turtles. Maybe after a dive you will have the following questions: 1) What kind of Sea Turtles are there? 2) How do you identify them? 3) What do they eat? 4) Why are there so many Sea Turtles around the Gili Islands? 5) What kind of turtles are around the Gili Islands? To answer all these questions it is maybe a good idea to start a Sea Turtle Awareness Distinctive Specialty Course with IDC Dive Resort Oceans 5. But what are the goals and prerequisites of this course? The Sea Turtle Awareness Distinctive Specialty course introduces divers and snorkelers to basic sea turtle identification and conservation. The goals of Sea Turtle Awareness course training are: • To familiarize students with the role of Project AWARE in preserving the aquatic environment. • To introduce sea turtle species common in temperate or tropical waters. • To provide students with the knowledge and skills needed to identify turtles and record sightings. • To inform students about decline in sea turtle populations, importance of sea turtles to marine biodiversity and what they can do to reduce the loss of sea turtles worldwide. Prerequisites for Sea Turtle Awareness course: • Student must be PADI Junior Open Water Diver or equivalent. Equivalency is defined as proof of entry level certification with a minimum of four open water scuba dives. Instructors must ensure divers can perform the skills required of PADI Open Water Divers. • Minimum age requirement: 10 years of age. For divers age 10-11, both a parent (legal guardian) and the diver must both watch the Youth Diving: Responsibility and Risks video or thoroughly review the Youth Diving: Responsibilities and Risks flip chart. Both parent (legal guardian) and diver must also read and sign the Youth Diving: Responsibility and Risks Acknowledgement Form. The course consists of two scuba dives or snorkel dives.

It is official! The Gili Islands have got another 6 new PADI Instructors. The training of the instructor has be done by Trawangan dive on Gili Trawangan and IDC Dive resort Oceans 5 Gili Air on Gili Air. Both PADI course directors Holly and Sander are very pleased that their students became a PADI Instructor. The next couple of days is for the fresh new instructors waiting till they will receive their teaching status sign, and the real instructor world begins. IDC dive resort Oceans 5 dive like to congrats her candidates Margot and Lewis to receiving their goal to become a PADI Instructor. Also Oceans 5 like to thank Examiner Marc for the relaxing days, and creating a nice atmosphere for the candidates. For more information about IDCs: http://www.indonesia-idc.com or our facebook page: https://www.facebook.com/Padi.instructor.development.courses.indonesia
The PADI IE has started. IE stands for Instructor Examination. This time Marc, a PADI examiner from PADI, flew over to evaluate the IDC candidates of Trawangan Dive and Oceans 5 dive resort. The day started with a short orientation, followed by exams and a class room presentation, all done in the restaurant of IDC dive resort Oceans 5. The restaurant was closed for a day but guest could have breakfast in front of the dive shop or at their room. The day started at 8.00, in the middle some time to prepare their classroom presentation, and finished at 16.00. Good new for all the Oceans 5 IDC candidates, Margot and Lewis, they passed the exams and their classroom presentation. Tomorrow it will a wet day. That means first confined open water, followed by open water. But so far so good!

A lot of people don't really understand the conditions of a shock. During the EFR training Gili Islands at IDC dive resort Oceans 5 dive Gili Air, the definition of shock will be well explained. Read this interesting article: http://www.humanillnesses.com/original/Se-Sy/Shock.html Shock is a dangerous physical condition in which the flow of blood throughout the body is drastically reduced, causing weakness, confusion, or loss of consciousness. It can result from many kinds of serious injuries and illnesses. If shock is not treated quickly, a person can suffer permanent organ damage and die. What Is Shock? "I studied for days, but I failed the test. I'm in shock," says one teenager to another. In everyday speech, "shock" is common and sometimes even fun. People line up to get shocked by horror movies. They want to feel an emotional jolt from seeing something sudden, surprising, and scary. Their hearts may beat a little faster for a moment, but when the movie ends they're as healthy as before. This kind of emotional shock has nothing to do with medical shock. "Shock" in the medical sense also can be sudden, surprising, and scary. But it is a very specific physical condition that is extremely serious. Shock occurs when the amount of blood reaching the brain and other parts of the body is reduced drastically; in other words, when the blood pressure falls very low. Since the blood carries oxygen needed by every cell in the body, the drop in blood flow deprives the cells of oxygen. The brain, the biggest user of oxygen, is affected, making the person confused, dazed, or unconscious. As cells struggle to function without enough oxygen, many chemical processes in the body are disrupted. Organs, including the lungs, kidneys, liver, and heart, start to fail. Unless the blood flow is restored quickly, the damage may be fatal. * aortic aneurysm (ay-OR-tik AN-yoo-rizm) is a weak spot in the aorta, the body's largest blood vessel. The weak spot can rupture or break, causing massive internal bleeding. What Causes Shock? There are several underlying causes of shock. Often, a case of shock involves two or all three of these types of underlying problems. These include: • There is not enough fluid in the bloodstream. This kind of shock is called hypovolemic (hy-po-vo-LEEM-ik) shock. It can be caused by heavy bleeding from an injury, such as a gunshot wound or wounds suffered in a car crash. It also can be caused by severe bleeding from a medical condition, such as an aortic aneurysm * or bleeding stomach ulcers. It can also occur if a person loses large amounts of fluids other than blood. That can happen, for instance, if a person has severe vomiting and diarrhea or has been badly burned over a large part of the body. • The blood vessels dilate (expand) too much. If this happens, blood pressure (the pressure within the blood vessels) can become so low that not enough blood is pushed out to reach vital tissues. The most common example of this kind of shock is septic (SEP-tik) shock, which is caused by a severe bacterial infection. • The heart fails to pump the blood strongly enough. This is called cardiogenic (kar-dee-o-GEN-ik) shock. It can be caused by many heart problems including a heart attack, an abnormal heart rhythm, a blood clot in the heart, or a buildup of fluid around the heart that presses on the organ, or by severe damage to a heart valve.

When you become an EFR Instructor you should know why it is so important to give CPR. During the IDCs at Oceans 5 dive resort it will clearly explained why and how CPR works during the EFR instructor Courses Gili Islands. This article gives you a good idea about CPR: www.livestrong.com Cardiopulmonary resuscitation, also known as CPR, is a set of basic emergency skills designed to help save a person's life when her heart has stopped beating or she has stopped breathing. The American Heart Association, or AHA, emphasizes the importance of CPR by stating that CPR, performed in an effective and timely manner, can double a person's chance of survival. [caption id="attachment_940" align="alignnone" width="300"] EFR Instructor courses Gili Islands with IDC dive resort Oceans 5 Gili Air Indonesia[/caption] Function of CPR The purpose of CPR is to provide critical body organs with oxygen-rich blood, according Medline Plus. CPR performs two basic functions: Chest compressions help maintain the circulation of blood throughout the victim's body to vital organs in the absence of a pulse, and rescue breathing, such as mouth-to-mouth, helps provide the victim's blood with oxygen in the absence of normal breathing. [caption id="attachment_941" align="alignnone" width="225"] EFRI Gili Islands with IDC dive resort Oceans 5 dive Gili Air Indonesia[/caption] Why Is CPR Important? When a person stops breathing or his heart stops beating, his body organs no longer are receiving the oxygen needed to stay alive, and the tissues will ultimately begin to die. The most vital organ that must be protected is the brain; in the absence of a pulse or respirations, a person's brain will undergo permanent damage after only four minutes, according to Medline Plus. Performing effective CPR keeps the blood oxygenated and keeps the brain supplied with the oxygen it needs to stay alive and avoid damage. Statistics The AHA states that, in the absence of CPR, a victim's chance of survival drops 7 to 10 percent for every minute that lapses between collapse and medical intervention. Every year, there are 294,851 cardiac arrests treated outside of the hospital in the United States. About 80 percent of all cardiac arrests that occur out of the hospital happen in homes, which emphasizes the importance of all capable individuals being trained to perform CPR. CPR Basics The foundational elements of CPR build off three simple steps, made easy to remember by AB-CABS. A stands for airway: After determining that the victim is unresponsive and calling for help, the initial step is to open her airway by tilting her head and lifting her chin. B stands for looking quickly for breathing. C stands for compressions, begin chest compressions, stopping every 30 compressions to give two breaths. CPR technique varies slightly for children and infants.

The Gili Islands IDC is over! The next 3 days is it only practice. Today we had theory in the morning and 2 confined sessions in the afternoon. It is still serious but the IDC candidates and PADI course Director Sander Buis are having a lot of fun. The skills of today for the IDC candidates were: * partial mask * regulator recovery * quick reverse * underarm push The candidates passed all the confined session with fantastic scores and they are ready for the PADI Instructor Examination (IE). The candidates didn't practice only 4 confined presentations, till now they have done 7 confined presentations, so they have practice a lot of skills. Oceans 5 dive resort stands for quality and like to implement their ideas about this also in the IDC. Our candidates are not trained to pass an IE but to become a full PADI Dive instructor.
