First time underwater nitrogen drunk

We all drink wine, drunk, drunk people, are not the same. I wasn't drinking, drunk, but this time, let me a lifetime, that is nitrogen. The so-called nitrogen drunk, is under pressure due to draw divers high partial pressure nitrogen and nitrogen affect the appearance of the narcotic, nerve and mental state similar like drunken state, this phenomenon is nitrogen. Air pressure in the four, the nitrogen pressure 3.2 atmospheric pressure, it produce anesthesia. Since diving, have not experienced in underwater nitrogen drunk, 6 February for a deep dive, I feel a nitrogen drunk, there is no danger of drunk. That day, head to the two Chinese students and coaches test results, on the day of the plan would only dive YAPAK once, the result of a dive in the morning because PETER to do translation for the exam, so another dive, diving sites in the ANGOL, depth of only 15 meters. Came back, with a Chinese beauty Lulu and a ready to learn a foreign fat technical diving, technical diving for foreigners, I do not worry, if technology is not good, will not have to learn technical diving. As for the Chinese beauty, but want to pay more attention to some, after all, not many diving experience. Reach YAPAK diving sites, I dived with Lulu, fat man behind, I use the compass side find diving sites of azimuth, looking computer table shows the depth of the dive. When you dive to 27 meters, I began to feel a bit going round the head, and more and more serious, and then look at the computer table, dive-31 m, at that time had not yet arrived at the location of the cliff, YAPAK already feel like eyes rested, I know this is already a significant nitrogen drunk, hard carrying yourself to make conscious and looking computer table side began to slowly rise to 25 meters, feel or no, Lulu and fat have been following me, maybe they don't know how I feel now, also not aware of the potential danger. I continue to use a compass to find the azimuth, while constantly remind myself to be calm. Mashita around, do not see the sea, its own start giggling, this is also the performance of the nitrogen and drunk, the control will be worse, but fortunately they are not found. Looked the computer table, discover also dropped to 30 meters of the location, I went on to start up, but do not know the reaction of nitrogen drunk at what depth to disappear, but I realized relatively sober. If rose to the position of the light, that even if this failed YAPAK diving, so can only remain at 25 meters. At this point, I looked up and saw a familiar fish, know the location of the cliff has arrived. The reaction of nitrogen drunk seem to be any better, at this time, Lulu la me, and point to the bottom, maybe 30 meters away from us, there is a white shark fin reef in slow moving, the reaction of nitrogen was drunk, some slow, when I was ready to take the camera, this shark swim away. I looked the computer table, and maintained in the 33 meters of depth, not for a moment, I see 2 shark, I let Lulu and fat man see, and walk, I began to wonder if that is not the illusion of nitrogen, drunk, or real see, anyway, is the reaction of nitrogen drunk has basically disappeared. I look at the pressure gauge, the pressure to show there are 100, they almost, I signed up, everyone started slow and took out diving buoy, good gas into the water, it begins to rise slowly along the rope to 5 meters location began to make safe, computer table shows need to do to stay of 8 minutes, takes a look at our gauges, air also have enough to do for almost 10 minutes after the safety stop, we rise in the water. Back to the ship, I took a deep breath, hugged is safe, head also slightly Halo, simply lying on the deck. Lulu is very excited, and the fat man in English communication to see sharks underwater, but I still recall the earlier case of nitrogen drunk, really dangerous, if some serious again, I might be asleep, directly into the deep blue, to another world. Abroad have a rule called 「introduction Martini rule 」 is at the level of nitrogen drunk described:

Diving around to 30 meters, nitrogen drunk level corresponds to drink a glass of Martini

40 meters, corresponds to the level of nitrogen drunk drink second Martini

50 meters, nitrogen level corresponds to the drink drunk three Martini

60 meters, corresponds to the level of nitrogen drunk drink four cups of Martini

70 meters, nitrogen level corresponds to the drink drunk five Martini

But not to drink a good person you are less likely to nitrogen drunk, alcohol consumption, with personal fitness.

To produce nitrogen drunk, you must have to float, floating nitrogen after drunken phenomenon will disappear.

Therefore diving with special emphasis on any time must be submerged with similar phenomenon occurs can help reduce the risk.

General symptoms of nitrogen drunk as follows:

Thinking about the dull but 30M conscious pleasure.

40M concentration disappears.

50M dizziness tense double.

60M loss of judgement.

70M loss of mobility.
