What Does HPNS Stand For?

HPNS stands for High Pressure Nervous Syndrome

High Pressure Nervous Syndrome (HPNS) is a physiological condition observed in divers exposed to high-pressure environments, typically at depths exceeding 200 meters (656 feet) during deep-sea diving. HPNS is characterized by a range of symptoms including tremors, cognitive disturbances, and behavioral changes, which are thought to result from the effects of increased partial pressures of gases, particularly helium, on the central nervous system. Understanding and managing HPNS is crucial for ensuring diver safety and performance during deep dives.
