The seriousness of the blockage depends on which part of the body is affected, the size of the gas bubble and the amount of inert gases unreactive gases within the diver's tissues. These conditions are very serious and can be fatal, particularly if the air embolism isn't treated quickly.
After a diver with an air or gas embolism has received emergency medical attention and their condition has stabilised, they'll be transferred to a hyperbaric chamber. They'll need to lie in the hyperbaric chamber for several hours, breathing a mixture of gases and oxygen in a pressurised environment. The high pressure restores normal blood flow and oxygen to the body's tissues, and reduces the size of the air bubbles in the body.
In cases of decompression sickness, the pressure forces the bubbles of nitrogen to dissolve back into the bloodstream.
The pressure in the chamber is then gradually reduced to allow the gases to leave the body, mimicking slowly surfacing from a dive. Although rare, it's also possible to get an air embolism during surgery or other medical procedures. Air embolisms caused by surgery, anaesthesia or other medical procedures can be difficult to treat. Treatment is usually needed to support the heart, blood vessels and lungs.
For example, fluids may be used to treat a fall in blood pressure, and oxygen may be given to correct reduced oxygen levels. Treatment in a hyperbaric chamber is occasionally needed in these cases. She also suffered from ear pain all week, making it hard for her to descend. I traveled with the group, too. And though my ears, teeth, and nose were fine, I had a few bouts of seasickness and post-diving fatigue that left me feeling dizzy and nauseous.
A few students threw up over the side of the boat on one particularly rough day. Scuba stands for "self-contained underwater breathing apparatus. Scuba apparatus includes a tank of compressed air toted by the diver on his or her back, a hose for carrying air to a mouthpiece, a facemask that covers the eyes and nose, regulators that control air flow, and gauges that indicate depth and how much air remains in the tank. A diver who stays down too long, swims too deep, or comes up too fast can end up with a condition called "the bends. Lauderdale, Fla.morolrifeebook.gq

For the most part, scuba diving is a relatively safe activity—as long as you have a healthy respect for the laws of physics. Basically, it all comes down to pressure. Even though you might not normally notice, air actually has weight. At sea level, As you go up in altitude, you encounter less air and less air pressure. That's why it's harder to breathe on top of a tall mountain.
In outer space, there's no air at all, and astronauts have to wear spacesuits to keep from blowing up like a marshmallow in a microwave. Underwater, the opposite happens. Water is nearly times denser than air and much heavier. As you dive deeper and deeper, the force of all that water can do funny things to your body. Ear pain is the most common problem, caused by an imbalance between air inside your ears and air outside your body. On an airplane or underwater, most people have to "pop" their ears to "equalize" the pressure.
Equalizing is harder for some people than for others, especially when they have colds or sinus congestion. Increased pressure underwater also affects how we breathe. At depth, pressure compresses the lungs. Divers take in more air as they descend, and their bodies absorb more nitrogen the deeper they go. One possible consequence is called nitrogen narcosis. Below certain depths, confusion can set in. He also tried to give his regulator to the fish. Jaundice : what conditions can be associated with jaundice.

What is decompression sickness? What are the symptoms? What if you or a friend have symptoms? Stop the dive and keep calm. If the diver is unconscious, give first aid.
But I can’t be bent!
Summon the emergency services immediately. Breathe pure oxygen if possible. Avoid over-exertion. Drink plenty of liquid. Any unusual condition after a dive could be decompression sickness. So if in doubt, get medical help. Why does it happen?
What happens when a scuba diver resurfaces too quickly and what is this called?
How is it diagnosed? What measures can be taken to avoid decompression sickness? Dive within the limits set out in the diving tables. Keep your rate of ascent to a maximum 10 metres a minute. Don't plan any dives that need a decompression stop in the water. Make a three-minute safety stop at a depth of 5 metres.

Don't dive more than three times in one day. If you plan more than one dive in one day, start by making the deepest dive first. If you are diving for several days in a row, have a dive-free day after two to three days.
Don't do any hard work before or after diving. Drink lots of liquid ideally oral rehydration solutions before diving. Lack of fluid due to heat or excess alcohol is dangerous. Make sure you are in good physical condition and well rested.

Have regular medical checkups. Make sure there is an interval of at least 24 hours between diving and travel by air or climbing up mountains. If you have had decompression treatment, the recommended interval before the next dive is at least 48 hours. Recovery after decompression sickness Mild forms of decompression sickness can resolve themselves without treatment or by breathing per cent oxygen at the site of the accident. How is decompression sickness treated?
At the diving station and during transport per cent oxygen by mask, at a rate of 10 to 15 litres a minute.
Give the diver plenty of fluid to drink. Give first aid if the diver is unconscious. Prevent the diver from exerting himself or getting cold. In hospital and specialised centres A decompression chamber is a steel tank that can be pressurised.
