What is a key symptom of Type 2 decompression sickness?

In Type 2 decompression sickness, one of the hallmark symptoms is the presence of neurologic central nervous system symptoms. This form of decompression sickness occurs when nitrogen bubbles form within the circulatory system and affect the nervous system, leading to a range of neurological manifestations. Symptoms might include confusion, dizziness, difficulty walking, or even paralysis, reflecting the serious impact that gas embolism can have on the central nervous system.

The central nervous system is highly sensitive to changes that occur during decompression, and when nitrogen bubbles obstruct blood flow or cause direct biochemical injury, it can lead to profound neurological effects. These CNS symptoms are often more severe than other types of symptoms associated with decompression sickness, such as joint pain or general fatigue. Recognizing these symptoms is crucial in diagnosing and treating decompression sickness effectively.
