When a diver gets the bends, the gas that forms bubbles in the bloodstream is nitrogen. This condition, also known as decompression sickness, occurs when a diver ascends too quickly from a deep dive, causing nitrogen gas that was absorbed at high pressure to form bubbles in the blood and tissues. These bubbles can block blood flow, leading to a range of symptoms including joint pain, dizziness, fatigue, and in severe cases, paralysis or even death.

To prevent the bends, divers must follow strict dive tables or dive computer guidelines to ensure a gradual ascent and allow the body to safely off-gas the nitrogen absorbed during the dive. It is also important for divers to stay well-hydrated, avoid alcohol before and after diving, and not dive while sick or fatigued.

If a diver does experience symptoms of decompression sickness, it is crucial to seek immediate medical attention. Treatment typically involves breathing 100% oxygen to help reduce the size of the bubbles and recompression in a hyperbaric chamber to safely eliminate the excess nitrogen from the body.

For more information on the bends and how to prevent decompression sickness, visit the Divers Alert Network website or consult with a certified dive instructor or medical professional. Remember, the bends can be a serious and potentially life-threatening condition, so it is important for all divers to understand the risks and take necessary precautions to dive safely.
