All About Scuba Diving

Scuba stands for self contained underwater breathing apparatus

, although today it is considered to be a word of its own. Scuba diving is a very popular sport but is also considered a profession and is widely used by the military for a variety of things.

Scuba diving is done with the aid of an air tank and breathing device which allows the divers to remain underwater for long periods of time. There are many things to do underwater such as cave diving and deep diving as well as wreck exploration. Scuba diving is used professionally for oil rig explorations and underwater construction.

It is important to have the proper training before beginning any type of underwater diving, especially underwater diving which involves deep depths of swimming. It is dangerous to surface too quickly or to stay underwater for too long, exhausting your air tank.

The term Scuba became popular as a reference to the rebreathers used in World War II combat by the United States. The first underwater device was known as an Aqualung. Many different professions today use scuba diving gear. Public aquariums use scuba diving gear when they go into their very large tanks to clean. This equipment is used by ship crews when they need to inspect or clean the ship underneath the water or inspect props.

Scuba gear is also important in search and rescue missions when people are lost from a boat or simply missing and thought to have gone into the water. It is also useful for search and recovery missions when something is lost in deeper water.

A popular use for scuba diving gear is for cave diving or wreck exploration. Many people enjoy swimming through caves and seeing the glorious sites underwater. Wreck exploration is a common use as well. Both of these past times are somewhat dangerous and should be approached with caution. There are many types of injuries associated with scuba diving. These injuries are broadly classified as barotrauma.

Basically, when diving there is a lot of atmospheric pressure surrounding the body, causing everything to place more pressure on the body, specifically the lungs, sinuses and ear drums. When scuba diving, it is important to remember to gradually reduce pressures instead of quickly to avoid these types of injuries. The most serious type of injury is known as decompression sickness. Decompression sickness occurs when a bubble of gas becomes trapped in the bloodstream of a diver. This happens when the diver rises to the surface too quickly.
