SUMMARY

Nitrogen narcosis is distinct from High-Pressure Nervous Syndrome (HPNS) as it involves a chemical effect rather than a purely physical one. HPNS occurs when gases like helium are used under pressure without significant chemical interaction. In contrast, nitrogen narcosis is attributed to the solubility of nitrogen in lipids, leading to a chemical anesthetic-like effect on the body. This differentiation is crucial for understanding the physiological impacts of gases used in deep-sea diving.

Not really, HPNS is normally only used for a completely physical effect when the gas under pressure has no chemical action. (like helium). Nitrogen narcosis seems to have a more chemical cause, solubilty in lipids - so is more like being chemically anesthetized
