What are common signs and symptoms of Type 1 DCS?

Type 1 Decompression Sickness (DCS), also known as "the bends," is characterized by the formation of nitrogen bubbles in the body tissues following a rapid decrease in pressure, such as during ascent after scuba diving or rapid altitude change. Common signs and symptoms associated with Type 1 DCS predominantly include pain, itching, and swelling.

The pain typically occurs in the joints and muscles, often described as severe and lingering. The itching can result from the nitrogen bubbles irritating the tissues, and swelling occurs due to inflammation and the accumulation of fluids in the affected areas. Recognizing these manifestations is crucial for immediate identification and treatment of Type 1 DCS.

While other symptoms like nausea and vomiting or headache and dizziness can occur in various medical conditions, they are not the hallmark signs of Type 1 DCS. Therefore, understanding the primary symptoms—pain, itching, and swelling—helps in quickly assessing and managing patients who may be experiencing this type of decompression illness.
