MeSH Heading: High Pressure Neurological Syndrome
Tree Number(s): C10.228.566; C24.410
Unique ID: D006610
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D006610
Annotation: in divers; do not confuse with INERT GAS NARCOSIS
Scope Note: A syndrome related to increased atmospheric pressure and characterized by tremors, nausea, dizziness, decreased motor and mental performance, and SEIZURES. This condition may occur in those who dive deeply (c. 1000 ft) usually while breathing a mixture of oxygen and helium. The condition is associated with a neuroexcitatory effect of helium.
Entry Term(s): Experimental High Pressure Neurological Syndrome; HPNS; High Pressure Nervous Syndrome; High Pressure Neural Syndrome; High Pressure Neurological Syndrome, Experimental
