What is decompression sickness


Decompression sickness, also known as "the bends," is a condition that occurs when a person experiences a rapid decrease in pressure after being exposed to high-pressure environments, such as deep-sea diving or ascending too quickly from a scuba dive.


When a person is underwater, the increased pressure causes the body to absorb more nitrogen gas into the bloodstream. If the ascent from the dive is too rapid, the pressure decreases quickly, and the excess nitrogen forms bubbles in the blood and tissues. These bubbles can cause various symptoms and complications.


The symptoms of decompression sickness can vary in severity and may include joint and muscle pain, fatigue, dizziness, difficulty breathing, chest pain, skin rashes, and neurological symptoms like numbness or tingling. In severe cases, it can lead to paralysis, unconsciousness, or even death.


Treatment for decompression sickness typically involves administering 100% oxygen to the affected person and placing them in a hyperbaric chamber. The hyperbaric chamber allows the person to breathe pure oxygen at a higher pressure, which helps to reduce the size of the nitrogen bubbles and promote their elimination from the body.


Preventing decompression sickness involves following proper diving protocols, such as ascending slowly and making decompression stops at specific depths to allow the body to gradually release the excess nitrogen. Divers should also adhere to recommended dive tables or use dive computers to monitor their ascent and avoid rapid changes in pressure.


It's important for divers to be aware of the signs and symptoms of decompression sickness and seek immediate medical attention if they suspect they may be experiencing it. Prompt treatment can help alleviate symptoms and prevent further complications.
