Peru has an uncle because he did not pay attention to one thing while diving, landed and found himself a "woman"! However, the truth is far less interesting than you think.
Underwater diving gave me a pair of "big boobs" ~
Not long ago, a hospital in Peru welcomed a very special patient. At first, the doctor thought it was a full-bodied aunt to see the doctor, but looked at the patient with a big uncle's face.
After questioning, it turned out that the patient was a real man, and his uncle's name was Alejandro Ramos Martinez, a fisherman who worked in the local fishing industry. Sometimes, for work needs, Uncle Alejandro would dive to the bottom of the sea to do some deep-sea operations and so on.
The tragedy took place just after a recent dive, when Uncle Alejandro went back to sea and landed as usual, and the whole person began to swell up like a balloon.
While examining the body, the doctor found that Uncle Alejandro's chest not only suddenly high rise, but also the upper arms on both sides of the rapid expansion. From the side, even Uncle Alejandro's stomach was full. The whole body was bulging like an inflated ball, and his arms now looked N times thicker than they had been.
And this terrible physical change is because Uncle Alejandro made a fatal mistake as he rose from the bottom of the sea, causing him to suffer from "stress disorder" (Decompression sickness).
When Uncle Alejandro rose too fast from the bottom of the sea, nitrogen in the body's blood formed a large amount of weird bubbles. Thanks to a large number of bubbles, Uncle Alejandro's body swelled rapidly after landing, turning into the exaggeration we now see.
Instead of giving him divine power, the exaggerated figure almost killed him. In addition to body shape changes, Uncle Alejandro also developed symptoms such as joint swelling, itchy skin, brain damage, paralysis, headache, cough, vertigo and nausea.
Decompression sickness is a nightmare for every diver, and many have lost their lives. If the rate of inadvertent rise is too fast, the consequences will be unthinkable.
However, a situation like Uncle Alejandro is extremely rare, because nitrogen is stuck in his muscles, causing him to be inflated. Miguel Alarcon, the attending doctor, arranged a decompression bin for his uncle, but only 30% of his nitrogen was discharged, and a large amount of nitrogen remained in his uncle's body.
If you want to completely remove this nitrogen from the body, surgery is an effective way, but Dr. Alarcon admitted: "the operation is very difficult, if the surgery requires a lot of risk."
This is a dilemma for Uncle Alejandro. On the one hand, physical suffering is enormous, on the other hand, high-risk unknown surgery. However, as far as the current situation is concerned, it is an iron fact that the uncle will leave the swimming world in his life.
Uncle Alejandro's experience is no doubt a tragedy, while wishing him an early recovery, he can not help but have many doubts. In the face of the increasingly popular island tourism, we live in Australia surrounded by the sea. If we want to try diving, what exactly should we pay attention to? How can I get a diver's license? Which people are suitable for deep diving?
Who can dive deep?
Not good at swimming
Some friends who have not tried snorkeling or diving, believe that diving must be able to swim. But that's not the case. Theoretically, people who are not good at swimming can dive, because swimming doesn't play a major role in the diving process. (but people who are illiterate in the water are more likely to be in a panic if they encounter an unexpected situation in the water.)
10 to 60 years of age
The age limit for diving is between 10 and 60. As long as the physical condition of the diving conditions of the person, you can try to experience diving.
How to get a diver's license in Australia
Generally speaking, diving is divided into two types, one is snorkeling (SNORKELLINT), the other is deep diving (SCUBA DIVING). As more and more islands become resorts, Australia has become a hot spot for divers.
On a global scale, there are now a number of institutions that are recognized as divers, such as PADI,CMAS,ADS,NAUI. The PADI (Professional Association of Diving Instructors) Professional diving coaches Association is currently recognized as the strictest and most popular professional diving qualification.
Many enthusiasts who love deep diving want to take an PADI certificate in Australia. In fact, it is not difficult to enroll. In most parts of Australia, institutions offering PADI diving courses can only log on to their official website, www.PADI.com,. Search your country area to find one of the most convenient diving schools to study.
OW/ Open Water Dive
OW (OPEN WATER DIVER) is the most basic diving course, trainees can learn diving skills, and diving with diving safety knowledge. As long as you know a little about swimming, healthy friends can sign up for the PADI course. Qualified students who have received the OW certificate can dive in the waters within their own experience, and the depth of diving is 18 meters.
AOW/ Open Water Advanced Dive
The AOW (ADVANCED OPEN WATER DIVER) diving course offers diving training for different specialties, such as night diving, boat diving, discharge, etc. Participants in the AOW diving course must be certified with OW or other diving qualifications of the same class, and the depth standard for a partner with a AOW certificate can be up to 30 meters.
Body taboo symptoms of scuba diving:
1. Have undergone middle ear surgery, or corneal surgery;
2. History of lung injury, especially spontaneous pneumothorax;
3. A person with a severe cold, such as a slug of nose;
4. Severe pulmonary obstructive disease, such as chronic emphysema or severe asthma;
5. Congenital diverticulum or pulmonary vesicular disease;
6. Having a history of epilepsy or cramps;
7. Frequent fainting and unknown causes;
8. Having a heart coronary artery disease, such as angina pectoris or having had a history of myocardial infarction;
9. Have red blood cell disease, such as sickle type red blood cell anaemia person;
10. Insulin dependent diabetes mellitus;
11. Long-term alcoholism or drug addiction;
12. Persons with mental illness;
These behaviors in diving can kill you.

During diving, sudden rapid rise can cause "decompression sickness". If it rises rapidly, the solubility of nitrogen in the blood decreases rapidly, and a large number of bubbles suddenly pop out of the blood before it can be drained out of the body. If it is blocked in the blood vessel, it will cause pain, severe joint muscle necrosis, and even loss of life.
Lung burst
Do not hold your breath in the process of deep diving, because as you rise, the water pressure around you will rapidly decrease, the inflated lungs will continue to expand and may explode, and someone has died of a ruptured alveoli while diving. But snorkeling is another situation.
Don't fly.
Usually, if you dive more than 12 meters deep, it's best not to fly for 24 hours (PADI standard). Because flying further puts people in a low-pressure environment, nitrogen cannot be discharged from the body, which can also cause decompression sickness, similar to the previous rapid rise.
