Which symptom is associated with skin manifestations in DCS?

The symptom associated with skin manifestations in decompression sickness (DCS) is a mottled and diffuse rash. In DCS, the formation of nitrogen bubbles in the body due to a rapid decrease in pressure can lead to various symptoms depending on the severity and location of the bubbles. The skin manifestations, which can include a mottled appearance, are indicative of nitrogen bubbles affecting the skin and underlying tissues. This type of rash may present as a "marbled" or blotchy pattern and is often accompanied by changes in color and texture of the skin.

Understanding these dermatological signs is crucial for recognizing DCS early, as skin symptoms can appear alongside more commonly known symptoms associated with DCS, such as joint pain or neurological signs. Identifying mottled and diffuse rashes can help prompt timely medical intervention to prevent further complications.
