The benefits of having a decompression meter

A decompression meter or computer indicates the diver the right decompression schedule which he should follow. These devices function by considering and measuring the changes in depth while the diver practices his activity and therefore giving him accurate and valuable information.

Having a decompression meter is very important due to the impact which the effects of pressure can have on a diver. When a change in the volume of an anatomical air space is such that passes the physical limit, a barotraumas happens. A barotraumas can appear as what is known as "squeezes" and as air embolism.

There also are some other indirect effects which might happen due to the pressure. Among these effects we can find two main ones which are nitrogen narcosis and bends. Bends is the name given to a decompression sickness that is caused when the body has nitrogen bubbles in some of its parts.

Bends or decompression sickness can show through the appearance of different symptoms. The most common symptom in which this problem shows is through a localized pain, usually in a leg and sometimes in an arm. Some other times, this problem can be detected when a person feels dizzy, has a paralysis, feels fatigue, has shortness of breath or even collapses and enters into a state of unconsciousness.

The symptoms which show that a person has nitrogen bubbles in their body can appear at different moments. Most of the times they occur around three hours after the dive, but sometimes they show within thirty minutes or one hour, and sometimes they appear as much as six hours after the diver has practiced the sport. If these symptoms appear, it is very important that the diver avoids going into the water again.

Therefore, having a decompression meter can actually help a diver avoiding several different problems which could even turn into permanent neurological defects. If a diver seems to have bends or decompression sickness, he should be treated without wasting time. Since sometimes the symptoms show hours after the nitrogen bubbles have appeared into the body, the sooner the diver is treated, the better.
