Peculiarities of multilevel diving with a dive computer

Previously there was an unspoken rule in amateur diving – the max time for a person spent under water equals the non decompression limit of a certain depth. This fact set a certain bans, with which a diver could not enjoy the underwater seneries long. His time spent under water was limited. But with the development of new technologies this have changed and now multilevel diving has become available to poeple, What is multilevel diving?

The technique of multilevel diving is based on the fact that at the time of surfacing the speed of oxygen saturation of a body decreses. This means that a diver has to make stops on certain depths stay there for a small period of time. This is required to a gradual nitrogen exiting from a body and decompression sickness prevention.

On diving courses for amateurs this practice has become habitual and allowed people to stay under water longer, and it is now restricted only by the oxygen supply and warmth. This diving technique has become possible due to the employment of underwater computer "Wheel" that calculates the needed stages and intervals.

What miltilevel diving offers a diver?

Multilevel diving offers a diver something what he came into diving for – the maximal time of being under water. In any body of water where bottom relief allows a diver to use this technique, dive computers can be used. This can be coral reefs, deep freshwater lakes, sunken ships and many more.

You start the surfacing with a maximal depth and gradually accend to the surface, making stops at control points. With the help of a dive computer this practice has become habitual. While you are on a certain depths you can explore a reef or enjoy the senery. It is not surprising that many divers consider a dive computer as irreplacable as a mask or fins,

Instructors of "AHLA" diving school will carry out training of multilevel diving with a dive computer, which will allow you to stay under water longer. We are waiting for you to go through our courses in our diving center in Eilat, Israel.

Efficient means against seasickness

Seasickness – is one of the main enemies of every person who sets off on trips to conquer seas or oceans. The reason for this usually lies on a genetic level. However in most cases seasickness is caused by a dissonance of information that is received by the brain from various sensory organs and the middle ear.

There are different ways to lessen or completely eliminate the symptoms of seasickness. If you want to enjoy diving in the Red sea with “AHLA-DIVE” but can barely endure waves – use the advice below.

Brain training

Receiving contradictory signals, the brain causes dizziness and nausea. It can be tricked and calmed by different methods.

The easiest and safest recommendations exclude the necessity of using medication:

• look into the distance. Put away your laptop or book. Focusing your eyes on stationary objects that are close to your eyes, you increase the difference of perceptions that come from the middle ear. It is better to look at the horizon. It is the most stable object.
• divert yourself to a pleasant conversation. Divert your attention. Find an interesting person to talk to. Dizziness and nausea will soon recede.
• take a stable position. The center of the ship at the top deck is swaying the least. Find yourself a comfortable place. Lean back on a wall and relax.
• avoid enclosed spaces. Fresh air helps to get rid of nausea. Do not lock yourself in the cabin.
• постарайтесь уснуть. Первый симптом морской болезни – сонливость. Если вам хочется спасть, и для этого есть удобное место, то воспользуйтесь данной возможностью.
• Try to fall asleep. The first symptom of seasickness is drowsiness. If you want to sleep and you have a comfortable place, go for it.

Diver training requires following the rules

Текст статьи:
Diving to great depths may bring unforeseeable situations. Divers should descend with one partner at least in order to react to equipment faulty, injuries and so on, belay one another or provide first aid in the situation becomes serious. Air supply must not stop and you need to get to the surface as quickly as possible following all the rules of a safe and appropriate surfacing. It is required to go through a diver training with experienced instructors on dry land, only then should you carry on to practical lessons in water.
Situation 1: second stage regulator failure
An emergency usually occurs at the time of diving into caves with narrow entries. Sloppy movements may lead to equipment hitting the stone surface. If one of the divers has a regulator failure he should use the octopus and compensator of his partner. When the diving equipment was not that perfect divers had to breathe in the breathing gas in turns, until they reached the surface. They even managed to surface from great depths.
Situation 2: intake valve on compensator is not working
This problem is not as difficult to solve as it seems. Such situations were successfully resolved two decades ago. What do you need to do? You should detach and reattach the feeding hose a few times. If this doesn’t help to fix the failure, you can try to inflate the compensator with your mouth.
Situation 3: inflation hose is not connected to the device
The hose needs to be back in place. But it sometimes happens that the valve at the end of the hose is jammed and the air is streaming out of the cylinder with sound. This may occur when there were repeated attempts to reattach the feeding hose to the intake valve.
Situation 4: cylinders slipped out the clip
Many divers fasten the cylinders to compensators with the help of plastic clips. They are very convenient to use, but plastic has its disadvantages. Cylinders may slip out the clip while plunging into the water as well as at the time of surfacing or getting in the boat. In order to prevent this one needs to check that the clip is ok from time to time.
If everything is developing in an unpleasant scenario, you can try and take off the compensator and properly install the cylinders. But if you have a partner with you, than he should deal with this responsible task. Your partner is will have to catch the slipping cylinders with his knees. He will use his hands to fasten the straps.
But it is important to inform you partner in trouble about your helping intentions. Your unexpected actions behind your partner’s back may cause confusion and sometimes even panic.
Coherent performance requires practice. It is important to not only have all the skills and knowledge, but also know your partner’s character peculiarities and foresee all his possible intentions. Otherwise there is a chance of misunderstanding when you all do different things at the same time. When you have only got seconds the right actions is what makes the difference between the life and death.

Diving center in Eilat invites everybody to enjoy the beauty of the Red sea. Our instructors will help you master the wisdom of underwater diving. Do not miss out on a unique chance to visit the unforgettable attractions and get tons of emotions that will be with you for the rest of your life.

Diver’s note: to drink or not to drink?

People see drinking alcohol as an ancient national tradition. Can you still follow it when you dive 30 meters deep and even deeper?  This very question causes much controversy among those who are really keen on diving.

Is it possible to combine diving and alcohol without any risk of damaging health? The answer seems obvious. What is more, recommendation to restrain from alcohol before and after diving was not just made up. Alcohol is forbidden by the PADI standards.

Does the amount of alcohol matter at the time of diving? It definitely does. When a person drinks a bottle of vodka, he loses his coordination and ability to think rationally on dry land to say nothing of the depths of the Red sea. The situation with such high dose is quite clear.

What if we consider just a can of beer or a shot of vodka? Such a dose does not cloud reason, the reaction remains adequate, a person is still able to put on the equipment and pay attention to what instructor says. Everything seems normal but unfortunately it is so only on the outside. The body is already experiencing an insignificant degree of dehydration. This very physiological state is very dangerous for a diver. One of the dangers is decompression sickness that is familiar to many diving beginners. To be safe one needs to pay close attention to his or her health and listen to the advice and directions of instructors at the time of diving training.

It is no coincidence that a person feels harrowing thirst during a hang-over, because any kind of alcohol dehydrates the body. When it happens of dry land, it is noting critical. When it happens under water different rules apply. A dehydrated body under water has a strong chance of developing a decompression sickness.

Experienced diving instructors always recommend drinking a lot of liquids at the time of training. Water thins the blood and provides its normal circulation. Intensive drinking regimen – is a golden rule of a safe diver. It needs to be mentioned that for a person who drank alcohol recently or in the very day of diving this is less effective. The risk of having a decompression sickness after drinking alcohol for a diver increases drastically, even if all the safety norms and surfacing rules are precisely observed.

One more question that is really important to divers is whether it is acceptable to drink alcohol after diving and if so, how much is allowed? You shouldn’t grab a beer to celebrate a successful dive having just stepped out of the water. At that moment the process of retaining B.U.N from the body is not yet finished. That is why any factors that cause blood thickening (alcohol) may provoke decompression sickness. If it is impossible to completely avoid having a drink at the day of diving than is should be put off. The first safe drink of alcohol a diver can have only 4-5 hours after the surfacing.

In case of a technical problem act according to the instruction!

Diving is one of the safest kinds of active rest if you follow the diving rules and make a timely maintenance of your diving equipment. However it is impossible to completely exclude the possibility of a technical faulty that is why a diver has to know how to act in case of emergency under water.

Failure of second stage of regulator being under water

Respiratory system of a person operates only when the pressure of the air delivered to the lungs is equal to the external pressure on the body. The difference between these pressures cannot be more than 14%. Second stage of regulator provides this equality when the air is supplied. In case of its failure you need to come to the surface using an alternative air source. Usually it is an octopus of a partner’s scuba. It is an additional second stage with a long hose. In case of emergency both divers can breathe in turn using one scuba on their way to the surface.

A breakdown of a regulator may occur due to its blow on underwater rocks. In such situations a diver has to be ready to solve the problem.

A jammed inlet valve of a buoyancy compensator

To try and unblock the inlet valve BCD, you should unplug and plug back in the feeding hose. If all the attempts of restoring the functionality of the valve that provides the air supply from the regulator are unsuccessful then a compensator can be inflated through mouth. Former generations of buoyancy compensator were design for this kind of usage.

Detached connecting pipe of a feeding hose from an inlet compensator valve

In such case connection of the details has to be restored. Sometimes in such case the valve is jammed in an open state, which is indicated by the sound of air leaking in the water. That is why it is important to stop the air feeding from the cylinder with the help of a stop-valve. Then you need to try and restore the functionality of the valve, attach the connecting pipe and open the air feeding.

The difficulty of the operation is connected to the uncomfortable location of the stop-valve behind the diver’s back. Only some divers with long arms and good mobility of joints can reach it. Diving partner can help block the stop-valve. If it needs to be done singlehandedly then you should loosen the waist strap and move the cylinders closer to the head. Not to face such problems some divers prefer to install them behind the back stop-valve facing down.

Dislocation of cylinders

Most divers attach their cylinders to the compensator using plastic clinches. If you haven’t checked the safety of the attachment then it may be loose and a cylinder may slip out. To try and put it in the right place you will have to take off the compensator. It is much more convenient to use the help of a partner. Holding the cylinder with his knees he will be able to fasten it tightly in the clinch using hands.

Being under water, pay close attention to your partner and follow instructions.

Дайверу на заметку: пить или не пить?

Люди воспринимают употребление алкоголя как старинную национальную традицию. Можно ли ей следовать, погружаясь на глубину 30 и более метров? Именно этот вопрос вызывает множество споров среди тех, кто искренне увлеченных дайвингом.

Можно ли совместить дайвинг и алкоголь без ущерба для своего здоровья? Казалось бы, ответ очевиден. Более того, рекомендация воздержаться от употребления спиртного до и после погружения возникла не сама по себе. Запрет на алкоголь установлен стандартами PADI.

Играет ли роль количество выпитого спиртного при погружении? Однозначно, да. Когда человек выпивает бутылку водки, то способность рационально мыслить и координировано передвигаться он утрачивает даже на суше, о глубинах Красного моря даже речи идти не может. С такой лошадиной дозой все предельно понятно.

А если речь идет всего лишь о баночке пива или одной рюмке водки? Рассудок такая доза не замутит, все реакции останутся адекватными, человек сможет надеть снаряжение, будет прислушиваться к наставлениям инструктора. Все нормально, но, увы, только внешне. В организме уже наблюдается незначительная степень обезвоживания. Именно это физиологическое состояние таит для дайвера множество опасностей. Одна из них – декомпрессионная болезнь, знакомая многим начинающим ныряльщикам. Чтобы себя уберечь, следует внимательно относиться к своему здоровью, прислушиваясь к советам и указаниям инструктора во времяобучения дайвингу.

Совсем неслучайно при похмелье человек испытывает мучительную жажду, поскольку любой вид алкоголя выводит из организма воду. Когда этот процесс происходит на суше, то ничего критичного не происходит. На глубине свои законы. Там обезвоживание организма – мощнейший катализатор, провоцирующий развитие декомпрессионной болезни.

Грамотные инструкторы по дайвингу всегда рекомендуют при занятиях пить побольше жидкости. Вода разжижает кровь, обеспечивает ее нормальную циркуляцию. Интенсивный питьевой режим – золотое правило безопасного дайвинга. Нужно сразу отметить: для человека, принявшего накануне или в день погружения алкоголь, он будет менее эффективен. Риск развития декомпрессионной болезни после принятия спиртного у давйвера повышается в несколько раз, даже если все нормы безопасности и режимы всплытия будут соблюдены неукоснительно.

Еще один принципиально важный для дайверов вопрос: допустимо ли употребление алкоголя после дайвинга, если да, то в каких дозах? Только выйдя из воды, хвататься за пиво или идти праздновать удачное погружение не стоит. В этот момент в организме еще не завершен процесс выведения остаточного азота. И поэтому любые факторы, вызывающие сгущение крови (спиртное) могут спровоцировать развитие декомпрессионной болезни. Если совсем избежать употребления алкоголя в день погружения не представляется возможным, его следует максимально отсрочить. Первую безопасную рюмку дайвер сможет поднять через 4-5 часов после всплытия.

Advice on maintaining a regulator

Most serious activities demand certain investments. Diving is not an exception. High quality underwater equipment costs a lot therefore it will take much money at first. Having paid a large sum for a professional set a diver wants to use it for a long time without any problems. And this requires proper and prompt service of every element. In this article we will be discussing breathing regulator. Efficiency of this detail is very important because it directly reflects longevity and safety level that is provided at the time of diving. Regulator checking is based on a few principals.

• frequency. Service is carried out before the process of diving and after it. You mustn’t miss any of the steps.
• execution of all professional recommendations. In this article you will find a step by step instruction, every step is very important.
• Attentiveness. Check the device with utmost attention: do not get distracted on other things while doing it and no detail will slip away from you.

Even if diving training is a closed chapter for you than repeating regulator maintaining peculiarities will not hurt. As it has been said the process is divided into two steps. We will explain each step separately.

Checkup before diving

It is carried out in a few steps:

1. To begin with attach the regulator to the cylinder than breathe in with its help a few times. After that you should repeat the same process with an octopus. The process is goes along with checking the readings of the pressure sensor they must be normal.
2. Then check the hoses. Entire surface without fractures or other damages is the only suitable state. Same thing with the mouthpiece: holes, fractures are unacceptable. Metal elements should be checked for quality: in a good state they don’t have any signs of corrosion.
3. If you have protective cases for hoses then they need to be taken off the first stage. This will help examine the hidden parts.
4. After the described procedures regulator needs to be taken off, change the cap that keeps dust off, take a deep breath on each regulator and keep vacuum. At this a working device issues a barely visible steam of air, but the air is not going backwards.
5. Last step: checking the carcass of the demand valve. They must be intact without any damage.

Getting ready for diving in Eilat do not forget this memo. If during a checkup you found small imperfections, turn to specialists immediately. Don’t risk using questionable equipment.

Checkup after diving

1. Rinsing the device, it is important to control the demand valve. It should not be pressed into. You also need to check the dust protecting cap, its ideal position is fastened to the construction.
2. For a thorough rinse bailout valve is put under a jet of water. Parts of demand valve are rinsed with a warm jet of water and it passes through the mouthpiece and comes out trough permit valve.
3. Hose that connects inflator of low pressure should be rinsed in warm water too. In doing so the sliding coupling should move back and forth.

If you do all the above mentioned procedures attentively and promptly you will be able to keep your equipment in the due state for a long time. But before going on diving vacation to Israel we recommend you to recall how to maintain your other diving equipment elements.

Проблема головных болей у дайверов

Modern medicine statistics states that many divers suffer from headache at the time of diving. During regular practices every diver experiences headaches from time to time. Moreover, some people regularly suffer from headaches as a result of being on the depth. From this article you will get simple advice on how to avoid headache at the time of diving training.

If such unpleasantness was a one-time case, there is no need to panic, however many deep diving enthusiasts complain of a systematic and quite strong headaches. Note, that the reasons for the pain may be the following:

• anxiety, stress;
• physical damage to ear or nose, caused by the difference in pressure (barotraumas);
• infectious diseases of ears and nose;
• swallowing of a certain amount of sea water;
• sudden immersion into cold water;
• too much pressure of a mask strap on the head;
• inflammation of the gums or sore tooth
• preceding pain in the mandibular joint;
• increased level of CO2;
• frequent migraines;
• cervical spondylosis;
• decompression sickness;
• hyperextension of neck muscles;
• Smoking before diving, using caffeine or other stimulants.

As you can see the reasons for possible discomfort may be quite various, and they are often found in a person’s medical card or in his lifestyle. It is possible to determine the source of pain with certainty with the help of a few additional questions.

What is the technique of cylinder fixation?

Many divers bent and stretch their neck for it not to be rubbed by a stop-valve. It becomes the reason of pain, that can be easily avoided – adjust the position of the cylinders so they do not touch your neck in its normal position.

How do you breathe and dive?

A too little amount of air usage can often be the reason of pains – carbon dioxide is accumulated in the body and causes discomfort. Too deep and lengthy dives as well as a fast ascent may cause a decompression sickness. In this case a diver needs immediate help.

Practical advice:

• Proper diving training – turn to professionals only;
• loosen a tight mask;
• try to relax at the time of diving;
• try to breathe slowly and deep;
• don’t strain your neck, turn with your body;
• keep a good physical form;
• don’t smoke or drink caffeine before diving;
• follow the safety measures;
• choose a wetsuit well not to get cold;
• Divers younger than 40 need to pass a medical check once in two years, older than 40 – every year.

It is important to choose a specialized diving center in Eilat, where a beginner will be set straight, helped with choosing the equipment and taught all the peculiarities.

Reliable mask – a key to incredible impressions!

Diving can be compared to a journey to a different universe, created by a talented science-fiction novelist. Sharp coral reefs, fantastic inhabitants of the underwater world, unusual plants and deep caves that keep secrets of the sea bottom and lots of other details give amazing emotions that will stay with you for a long time! No wonder that diving training has become one of the most demanded services – every person wants to plunge into this other universe, a feeling that is comparable with a flight in space.

How to choose a mask for underwater exploration?

Diver’s way is thorny and dangerous, but very interesting! Danger awaits the brave adventurer on every corner of his challenging path, but these are not monsters or predators that inhabit the deep caves. The main threat is in careless preparation before diving. The most common problem of all beginners is a leaking mask. When the “skirt” sealed to the frame does not match the face of the diver, the mask starts leaking. Experienced divers say that faces leak and not masks, but despite the harsh professional humour, the problem is still quite relevant.

Entering an equipment store beginners are lost because of the wide selection. The “skirts” of the masks used to be made of rubber. Due to the features of this material the number of colors was limited to black and green. Technological advance has brought divers silicone that became a new step to a more comfortable diving. This material is long-lasting and doesn’t irritate skin as much as rubber does. Composite materials are more complex – their characteristics depend on the initial components.

We recommend using equipment of famous brands. Large manufacturers live up to their reputation and try to provide a customer with a quality product according to the price. Cheap equivalents of Thai handymen are no match to masks of European producers. Cheap masks are less reliable.

Checking how well a mask fits the face is quite difficult in regular conditions. Most beginners learn about the leaking only after the immersion. Pressing the mask against the face and breathing in is useless – you will feel that the “skirt” is tightly adhere to the face, but at the time of diving the water will still penetrate through small holes.

Mask adjusting should be done in the water. We recommend you to check how easy it will be for you to block the nostrils in a thick glove. If you find it difficult during a check then during equalizing you will surely experience problems. Check if you can adjust the mask strap with one hand. At the time of our underwater journey your other hand may hold a video camera, a torch or a photo camera – then you will have to adjust the strap with one hand.

The lighter the mask the tighter it stays in the place. The number of lenses doesn’t really matter. The most popular are twin lens masks – they are comfortable and very clear. Additional lenses at the sides provide a fuller visibility and simplify reading of the devices such as pressure gauge. Men should choose the mask even more carefully if they don’t want to lose their facial hair before going to the dive-center. Some masks, that provide total tightness, may leak because of a mustache or a beard. A good diving mask is a key to the fullness of emotions from a fascinating journey in the underwater world.

Diving: a sport or a way of life?

When we talk about diving, we mean a young and perspective kind of active leisure. In the world it has become popular about twenty years ago – previously there were swimming sections but they are not the same thing. Nowadays there are various training programs of the art of water immersion – from scuba diving (trial lesson about 30 minutes) to a full diving training course (theory and practice in the swimming pool and later in the open water).

Aspects of modern diving

First – diving training is compulsory, whereas theory and practice are equally important. You must do what you understand, mind the safety rules and so on. Are you sure that you will be able to learn all the related information on your own?

Diving should be carried out under the supervision of an instructor: first in the swimming pool, then in the open water. You can practice diving on your own only after a series of trainings – you don’t start driving a car right after reading the rules, same here, what is more diving on a significant depth can be dangerous.

Swimming perfectly in one place doesn’t mean excellent diving everywhere. There are regional peculiarities and differences that cannot be ignored.

Not all diving centers will accept your certificate, especially if you received it in an unknown school. Mind this to prevent unpleasant surprises.

On an underwater wave

In conclusion we would like to say that diving is rather a way of life than a sport. If you are interested in this active leisure, finish a diving training course in AHLA DIVE, get a certificate and open a wonderful underwater world to yourself.

Заниматься дайвингом нужно соблюдая правила

При погружениях на большую глубину могут происходить непредвиденные ситуации. Аквалангисты должны спускаться, как минимум, в паре, чтобы вовремя отреагировать на отказ снаряжения, на травмы и прочее, подстраховывая друг друга и оказывая первую помощь, если положение дел становится очень серьезным. Нельзя чтобы прекращалась подача воздуха и нужно как можно быстрее подняться на поверхность воды, соблюдая все правила безопасного, правильного всплытия. Требуется пройтиобучение дайвингу у опытных инструкторов на суше, а только потом приступать к практическим занятиям на воде.

Ситуация 1: отказ работы регуляторов второй степени

Обычно критическая ситуация возникает, когда происходит погружение в пещеры, вход в которые осуществляется по узким ходам. При неаккуратных движениях возможны удары о каменистую поверхность. Если у одного из аквалангистов отказал регулятор, то нужно воспользоваться октопусом и компенсатором напарника. Когда снаряжение ещё не было столь совершенным, то водолазы по очереди дышали дыхательной смесью из одного акваланга до тех пор, пока им не удавалось всплыть на поверхность. И ничего, умудрялись подниматься даже с больших глубин.

Ситуация 2: не срабатывает впускной клапан на компенсаторе

Эту проблему не так сложно устранить, как кажется на первый взгляд. С подобной задачей успешно справлялись ещё два десятилетия назад. Что нужно делать? Следует несколько раз отсоединить и присоединить обратно питающий шланг. Если не удалось устранить неисправность, можно попробовать с силой надуть компенсатор ртом (орально) .

Ситуация 3: шланг инфлятора плохо подсоединен к устройству

Штуцер необходимо вернуть на его место. Но случается и так, что происходит заклинивание клапана, расположенного в конце шланга и воздух с шумом покидает баллоны. Такое может произойти если были неоднократные попытки отсоединить и обратно присоединить питающий шланг к впускному клапану.

Ситуация 4: баллоны выскользнули из зажима

Крепление баллонов к компенсаторам многие водолазы осуществляют при помощи пластикового зажима. Он очень удобен в использовании, но пластик есть пластик. Выскользнуть из зажима баллоны могут как во время погружения в воду, так и при подъеме на поверхность или в лодку. Чтобы этого не произошло, нужно время от времени внимательно посматривать, все ли в порядке с креплением.

Если все же события пошли по неприятному сценарию, можно попробовать снять компенсатор и установить баллоны как положено. Но если рядом напарник, то это ответственное задание лучше будет поручить ему. Ваш товарищ должен успеть задержать ускользающие баллоны, придержав их коленями. Руками в это время он затянет крепления.

Но попавшего в неприятности аквалангиста лучше предупредить о своих намерениях. Пристроившийся за спиной напарник, тормошащий товарища невесть почему, вызовет у виновника событий в лучшем случае недоумение, а в худшем – панику.

Слаженная работа не происходит сразу. Нужно не только владеть определёнными знаниями и навыками, но и знать особенности характера напарника, предугадывать его возможные намерения. Иначе может возникнуть ситуация, как в басне про лебедя, щуку и рака. А когда счёт идёт на секунды и от правильных действий зависит жизнь человека – это недопустимо.

Научись преодолевать азотный наркоз!

Азотный наркоз частенько называют дайвингом в нетрезвом виде. И это не так уж далеко от истинного положения вещей. Это состояние знакомо большинству людей, которые погружались на глубину двадцать пять и более метров.

Что представляет собой азотный наркоз

Азотный наркоз распознать не так сложно, главное — знать симптомы. Сюда относятся:

• непонятная эйфория;
• замедленные реакция и мышление;
• головокружение.

Как правило, об этом рассказывает инструктор во время обучения дайвингу. Но некоторые дайверы описывают состояние совершенно иначе: приступы паники и тревога. Истый механизм развития такого состояния до сих пор вызывает много споров, однозначного мнения по этому поводу нет. Единственное, в чем сходится большая часть специалистов: развивающиеся симптомы очень схожи с начальной стадией общей анестезии.

Азотный наркоз: раскрываем тайну возникновения

Точная причина развития наркоза под воздействием азота точно не установлена. Проводимые исследования лишь выявили, что и иные инертные газы, если их вдыхать под низким давлением, также действуют наркотически. Но наиболее действенным оказался азот.

Существует гипотеза, что азотный наркоз появляется в результате растворения молекул газа в жировых прослойках нервной ткани. Под его воздействием синапсы нейронов блокируются и становятся невосприимчивыми к химическим, электрическим сигналам. Другими словами, мозг дайвера перестает или начинает замедлено реагировать на окружающую его обстановку. Вероятность развития наркотического опьянения усиливается с глубиной погружения.

Можно ли справиться с наркотическим воздействием?

При погружении на глубину 24 и более метров возникает риск развития азотного наркоза – это утверждение нужно принять и запомнить. Очень важно вовремя осознать его наступление, и быстро принять меры по минимизации негативных последствий. Необходимо, соблюдая все правила всплытия, изменить глубину на меньшую: такую, где самочувствие нормализуется. После этого рекомендуется завершить погружение или продолжить его на мелководье.

Чтобы азотный наркоз преодолеть, рекомендуется:

• не употреблять алкоголь накануне погружения;
• хорошо отдохнуть и верить в свои силы;
• использовать только качественный регулятор;
• отработать до автоматизма основные навыки обеспечения безопасности;
• сохранять отличное настроение.

Еще один важный совет – преодолевать новые глубинные пределы следует постепенно. К каждому уровню необходимо привыкнуть, оценить как на увеличившуюся глубину реагирует организм.

Израильский дайвинг-центр в городе Эйлат в своей работе неукоснительно придерживается международных стандартов дайвинга: во всех погружениях у каждого должен быть напарник. И не просто для компании. Достаточно часто человек даже не осознает, что находится в состоянии азотного наркоза, и это крайне опасно. Каждые 2-3 минуты с напарником следует поддерживать коммуникацию. Любое промедление или пропуск договоренности может быть признаком развития наркотического состояния.

Существует такое понятие, как адаптация к наркозу, проявляющееся в ослабевании воздействия азота на организм. Об этом рассказывали многие дайверы, имеющие опыт глубинных повреждений. Почему так происходит тоже пока не выяснено.
