High Pressure Neurological Syndrome - an overview ...

High-Pressure Nervous Syndrome. High pressure induces a constellation of symptoms consisting of tremor, ataxia, nausea, and vomiting that is known as the high-pressure nervous syndrome (HPNS). 120 It occurs at an ambient pressure greater than 15 to 20 ATA and was first described during the compression phase of deep dives with a helium-O 2 ...

High-pressure neurological syndrome (HPNS)

High-pressure neurological syndrome (HPNS) is a condition encountered in diving beyond a depth of 100 m. Manifestations include headache, tremor, myoclonus, neuropsychiatric disturbances and EEG changes. Convulsions are seen only in experimental animals. Most of the changes are reversible on surfaci

2020-12-28 · What is high altitude syndrome? High altitude syndrome typically appears on rapid ascent to altitude above 2,500 metres (8,000+feet), e.g. flying directly to Lhasa or La Paz from sea level. It is caused by the lowering of atmospheric oxygen pressure when ascending to high altitudes. The human body will

1997-12-29 · High-pressure neurologic syndrome is a condition encountered in deep-sea diving beyond a depth of 100 meters, a feat that is made possible by the breathing of special gas mixtures such as helium and oxygen (heliox). It is characterized by neurologic, psychological, and electroencephalographic abnormalities. In 1967, Bennett described a decline ...
