Decompression Sickness Decompression sickness‚ also known as the bends‚ is a term used in scuba diving to describe the sharp‚ painful feeling that occurs when one surfaces too quickly. Although it is not very common‚ it can potentially be fatal if severe enough. The symptoms for the bends are easily identified and are simple to treat if it is caught in the early stages. Decompression sickness can be prevented all together if proper safety precautions are taken. If you pay attention in certification

Aircraft Pressurization System Airplanes‚ which do not have pressurization and air conditioning systems‚ are usually limited to the lower altitudes. They need to stay below 8‚000 feet. A cabin pressurization system accomplishes several functions in providing passengers comfort and safety. It maintains a cabin pressure altitude of approximately 8‚000 feet at the maximum designed cruising altitude of the airplane‚ and prevents rapid changes of cabin altitude‚ which may be dangerous to the passengers

EFFECT OF ATMOSPHERIC PRESSURE ON THE ENVIROMENT THE BIOSPHERE Variations in atmospheric pressure can present special problems for the respiratory systems of animals because atmospheric pressure affects the exchange of oxygen and carbon dioxide that occurs during animal respiration. Normal atmospheric pressure at sea level is the total pressure that a column of air above the surface of the Earth exerts (760 millimetres of mercury‚ or 1 atmosphere)

Premium Oxygen Decompression sickness
"The Bends" is also known as decompression sickness or caisson sickness. When a person is scuba diving‚ the water pressure increases as he or she goes down further. As depth increases‚ the pressure of the air breathe must also increase‚ causing more of the air to dissolve in the bloodstream of that person. The main components of air are oxygen‚ which is continuously used by the body‚ and nitrogen‚ which isn’t used by the body‚ so when a diver ascends or rises too quickly to the surface‚ the pressure
