What are the symptoms of nitrogen narcosis?
Symptoms of nitrogen narcosis include: wooziness; giddiness; euphoria; disorientation; loss of balance; loss of manual dexterity; slowing of reaction time; fixation of ideas; and impairment of complex reasoning. These effects are exacerbated by cold, stress, and a rapid rate of compression.
Here's a look at some of the best tips we've come across to avoid decompression sickness and minimize the risk of ever experiencing it ourselves:
- Plan,Plan, Plan.
- Don't dive drunk or high.
- Stay hydrated.
- Adhere to safety stops and a slow ascent rate.
- Don't fly immediately after diving.
- Recompression therapy. Any other symptoms of decompression sickness indicate the need for treatment in a high-pressure (recompression, or hyperbaric oxygen) chamber, because recompression therapy restores normal blood flow and oxygen to affected tissues.
- The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you'll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.
- Thus, the deeper you dive, the faster you consume air from your scuba tanks, no matter how much air it holds to start with. So how long does a scuba tank last? The average beginning diver's air consumption in calm waters runs a tank close to empty in around 1 hour at 10m depth (compared to just a few minutes at 40m).
Decompression sickness: Often called "the bends," decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body's tissues. This doesn't cause a problem when a diver is down in the water.
- To safely ascend from a deep scuba diving session, divers must remain at each particular depth until sufficient gas has been eliminated from the body, each of these is called a decompression stop. "If you have access to oxygen, a mask should be applied to the diver as soon as possible."
- Man Sets New World Record For Deepest Scuba Dive After Plunging More Than 1,000 Feet. Scuba organizations say recreational divers shouldn't go below about 130 feet, but one Egyptian diver recently ventured a bit deeper -- going more than 1,000 feet below the ocean surface and setting a world record in the process.
- As you feel the pressure beginning to build do the following:
- Hold your nose, close your mouth.
- Turn your head to the right until your chin touches your shoulder.
- Swallow hard until your left ear pops.
- Turn your head to the left until your chin touches your shoulder.
- Swallow hard until your right ear pops.
Scuba diving, while enjoyable, does carry the risk of decompression sickness, also known as "the bends." It is a serious, and potentially lethal disease, but treatable if diagnosed early. Serious cases of the bends can result in coma or death.
- Barotrauma typically occurs when the organism is exposed to a significant change in ambient pressure, such as when a scuba diver, a free-diver or an airplane passenger ascends or descends, or during uncontrolled decompression of a pressure vessel such as a diving chamber or pressurised aircraft, but can also be caused
- The bends, also known as decompression sickness (DCS) or Caisson disease occurs in scuba divers or high altitude or aerospace events when dissolved gases (mainly nitrogen) come out of solution in bubbles and can affect just about any body area including joints, lung, heart, skin and brain.
- A recompression chamber is a hyperbaric treatment chamber used to treat divers suffering from certain diving disorders such as decompression sickness. When hyperbaric oxygen is used it is generally administered by built-in breathing systems (BIBS), which reduce contamination of the chamber gas by excessive oxygen.
