High-pressure nervous syndrome - Wikipedia
High-pressure nervous syndrome (HPNS – also known as high-pressure neurological syndrome) is a neurological and physiological diving disorder which can result when a diver descends below about 500 feet (150 m) using a breathing gas containing helium.
High-Pressure Neurological Syndrome - StatPearls - NCBI Bookshelf
2024年10月9日 · High-pressure neurological syndrome (HPNS) is a condition that occurs during deep-sea dives exceeding 150 meters and is characterized by neurological, psychological, and electroencephalography (EEG) abnormalities. The severity of HPNS symptoms is influenced by both the rate of compression and the level of hydrostatic pressure reached.

2024年10月9日 · High-pressure neurological syndrome (HPNS) is characterized by neurological, psychological, and electroencephalographic (EEG) abnormalities and typically occurs during dives deeper than 150 meters. [2] . This feature requires the diver to use helium-oxygen gas mixtures.
High pressure neurological syndrome (Concept Id: C0019537)
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.
High Pressure Neurological Syndrome - DIVER magazine
2012年1月17日 · High Pressure Neurological (Nervous) Syndrome (HPNS) is a similar problem that is experienced on deeper dives. It is a difficulty that recreational divers will never experience but advanced technical divers are increasingly performing dives where this is a reality.
High pressure nervous syndrome - wikidoc
High pressure nervous syndrome ( HPNS) is a neurological and physiological diving disorder that results when a diver spends too much time breathing a high-pressure mixture of helium and oxygen ( heliox ). [1] . HPNS is a limiting factor in future deep diving.
What is High Pressure Nervous Syndrome (HPNS)? - DiverTown
High Pressure Nervous Syndrome (HPNS) is a neurological and physiological condition that affects individuals exposed to high-pressure environments, primarily encountered during deep-sea diving and underwater activities.
High-pressure neurologic syndrome (HPNS) - MedLink Neurology
1997年12月29日 · High-pressure neurologic syndrome is a condition encountered in deep-sea diving beyond a depth of 100 meters and is characterized by several neurologic and psychiatric symptoms and signs. The effects are primarily due to excessive atmospheric pressure on different CNS structures.
High-Pressure Neurological Syndrome - PubMed
2024年10月9日 · High-pressure neurological syndrome (HPNS) is characterized by neurological, psychological, and electroencephalographic (EEG) abnormalities and typically occurs during dives deeper than 150 meters. This feature requires the diver to use helium-oxygen gas mixtures.
High Pressure Nervous Syndrome | Deep Diving Maladies
HPNS or High Pressure Nervous Syndrome (also called High-Pressure Neurological Syndrome) can onset beyond a depth of 150m/500ft when using heliox or trimix breathing gasses. The severity of HPNS is determined by the speed of descent (rate of compression), depth attained (absolute pressure) and the percentage of helium inspired by the diver.
