What is type 1 DCS characterized by?

Type 1 Decompression Sickness (DCS) is primarily characterized by pain, often referred to as "the bends." This form of DCS is typically associated with the formation of nitrogen bubbles in the body as a diver ascends too quickly after a dive, which can lead to symptoms like joint pain and skin rashes. The symptoms arise from bubbles causing irritation or damage to tissues and joints, leading to pain that can sometimes be quite severe.

Understanding the distinction of type 1 DCS from type 2 is important. Type 2 can present with more severe symptoms such as neurological deficits, respiratory issues, and even loss of consciousness, which elevate the potential for immediate life threats. However, type 1 DCS does not generally involve these acute life-threatening symptoms or neurological complications; thus, it is primarily described by painful sensations. The focus on pain as the primary symptom helps divers recognize the condition and seek appropriate treatment, typically involving recompression therapy.
