What are the signs of decompression sickness in divers?

The signs of decompression sickness, often referred to as "the bends," typically include joint pain, dizziness, difficulty breathing, and skin rashes. Joint pain is commonly experienced because nitrogen bubbles can form in the joints as a diver ascends too quickly, leading to pain similar to that of arthritis. Dizziness can occur due to changes in gas pressures affecting equilibrium within the body. Difficulty breathing results from nitrogen bubbles interfering with blood flow and potentially affecting the lungs. Skin rashes, which may manifest as mottled skin or hives, can indicate the presence of gas bubbles in the microvasculature of the skin. Recognizing these symptoms is crucial for divers, as timely treatment can prevent severe complications.

Other signs like headaches, fatigue, nausea, fever, and loss of consciousness can occur in different medical emergencies or conditions but are not specific indicators of decompression sickness. Understanding the hallmark signs is important for divers to respond appropriately in case they or someone else experiences symptoms of this condition.
