Which of the following is NOT a symptom of DCI?

Diving-related Decompression Illness (DCI) encompasses a range of symptoms due to nitrogen bubbles forming in the body during or after a dive. Each of the other symptoms listed—paralysis, dizziness, and extreme fatigue—are recognized manifestations of DCI.

Paralysis can occur if nitrogen bubbles affect the central nervous system. Dizziness often results from bubbles impacting the inner ear or affecting circulation to the brain. Extreme fatigue is also common due to the physiological stress placed on the body during a dive and the subsequent complications of DCI.

In contrast, fever is not typically associated with DCI. While fever may arise due to unrelated factors or infections, it's not a direct symptom of decompression illness. Understanding the distinct symptoms of DCI is critical for divers to recognize and respond appropriately in emergency situations.
