Scuba Diving

SCUBA, abbreviation of Self-Contained Underwater Breathing Apparatus is very exciting and enjoyable. A lot of people think that under water diving (SCUBA diving) is all about wearing a wetsuit and fastening an oxygen cylinder on your back. There are a lot more things associated with diving in terms of effort, time and exertion.

In 1943 scuba diving was initiated as a sport by Jacques Cousteau and Emil Gagnan with the invention of the Aqua-lung. Since the past 20 years scuba diving has become exceedingly well known. Around 700,000 divers all over the world are certified every year as the activity of diving has grown tremendously.

Common medical problems of scuba diving

There are a number of medical problems associated with scuba diving. One of the most common is “squeezes.” It can affect a person’s face mask or middle ear at the time of diving. It also causes severe pains in a person’s ears. Severe throbbing in the ear is due to the higher water pressure because as you go deeper in the water, the pressure rises.

Various kinds of marine animals, and dangers like for instance sharp metal which is bare or fishing lines etc, cause minor injuries like cuts, scratches, scrapes to a persons arms and legs.

Dangers of scuba diving

Every sport involves danger whether it is football, cricket, baseball etc, but a lot of divers state that scuba diving is very safe as compared to other sports. They say it is even safer than touch football. There are a lot of dangers involved in scuba diving which are very obvious. One of the most obvious being, that a person is about 20 to 80 (or above) feet under water for about an hour wearing a mask and an oxygen cylinder on the back. There are a number of things which might go wrong like for instance the mask or the mouthpiece might fall out or the equipment oxygen cylinder could break down. (Mccarthy, 1997)

Amongst all the other health issues barotrauma to the lungs and decompression sickness are the most hazardous ones. These are also called “the bends.”

Barotrauma arises when the gas contained in the lungs expand while the diver is going up to the surface level of the water, harming nearby body tissues. These lung damages are usually terrible enough to be the basis of lung collapse (pneumothorax). The damages can also let the free air bubbles to get out into the blood flow. This is called arterial gas embolism. Arterial gas embolism frequently causes chest pain, inhalation difficulty and neurologic troubles for example stroke. (American Family Physician, 2001)

Decompression disease takes place at some point in rising and on the surface level. The nitrogen gas merges with the body tissues due to which blood oozes out from the solution and it also forms minute bubbles in the blood. The blood vessels and the body tissues might get blocked or injured due to the bubbles. The commonly known signs of Decompression Sickness (DCS) are the convulsion of brain, spinal cord and lungs.

The pressure of the water is very hazardous for the gases in a person’s body, but before being compressed by the pressure of the water the diver has to go very deep in the water. In physics Boyle’s Law of gases state the proportionality of the volume of gas to its pressure. Like for instance if a person goes 30 feet deep into the water and breathes air from the oxygen tank and then comes up to the surface of the water without breathing out, the air in the lungs will expand to twice the times of its volume which will in return cause immense pain in a persons lungs.

Various other problems occur due to the pressure of gas, one of them being Decompression Sickness (DCS) which s also known as “bends”; it is the accretion of residual nitrogen in the tissues of a person’s body. Auspiciously, a lot of dangers associated with diving can be evaded by getting proper training and also being in a good physical state.

Common Medical Problems In Scuba Diving

Severe medicinal harms are rare in scuba diving. Each year the approximate number of deaths occurring from scuba diving is not more than 90, while each year there are millions of dives worldwide. Besides, not more than a thousand divers all over the globe need recompression treatment to take care of severe health issues related to diving.

Scuba Diving Certification Training Agencies

With the intention of learning scuba diving as it should be and safe and sound, it is very important to take the necessary certifications obtainable from one of the well-known scuba diving training agencies. This will make sure that the diver is trained with the right practical background information in addition to the useful talent necessary to be a certified scuba diver. At the moment a lot of these scuba diving training agencies can be found. There is not only one best scuba diving training agency. The largest provider of scuba diving certificates is the National Association of Underwater Instructors (N.A.U.I).

The experience and knowledge of the trainer is a more significant issue in determining how flourishing a trainee will be in learning the skill of scuba diving. The learner’s own hard work and conscientiousness also play a significant role. A lot of diving trainers in reality hold official recognition cards from a number of different scuba diving training agencies. Generally speaking, there has been no connection between the occurrence of disasters related to diving and different scuba diving training agencies. As a matter of fact, lack of dive practice, particularly fresh experience, has been considered to be the main reason of dive associated disasters.

Countries Using Resources on Scuba Diving

The security and utilization of undersea resources has been the most important administration concern all over the globe. It is seen that the increasing attractiveness of scuba diving has caused overcrowding and ecological harm to the sites where diving is considered as a major activity. Coral reef environmentalists are taking into view the harm which is caused by the divers who are not very experienced, who disturb delicate reef surroundings by moving up sediments, acting together with reef animals and leaving waste (Fishman, 1991). General public, tourism experts, administration groups and society developers related to the safety and utilization of marine cultural resources have started working jointly to build up strategies on the topic of marine resources.  Scuba divers participate greatly in this hard work due to their close interface with marine resources and their prospective for growing economic impacts to the home society. Leisure scuba diving is a speedily increasing part of the marine activity especially for the tourists.  In 1991, it was found out that there are above four million trained Scuba divers in the United States, and it was predicted that the number of divers will raise all over the globe by no less than 10 million in the duration of the 1990s.

One more issue fueling development in diving is the altering nature of the market. According to a research, 40% of the total skilled divers are women. For the reason that anybody can take part, Scuba diving is considered as one of the world’s fastest increasing family activities. “In the past, recreational Scuba was viewed as an activity limited to young men who left their wives or children on the beach while they enjoyed the underwater sights.  Today, everyone’s getting in the water and they are enjoying it so much that they’re coming back time and time again” (Young ; Atkinson, 1997).
