Summary
High pressure nervous syndrome causes tremor during deep diving. Tremor begins at 150 meters and worsens with increased pressure, potentially involving central and peripheral mechanisms.
Area of Science:
- Physiology
- Neurology
- Diving Medicine
Background:
- High pressure nervous syndrome (HPNS) is a neurological complication of deep diving.
- Tremor is a key symptom of HPNS, but its precise mechanisms are not fully understood.
Purpose of the Study:
- To investigate the onset and progression of tremor in hyperbaric conditions.
- To explore the potential central and peripheral mechanisms underlying HPNS-induced tremor.
Main Methods:
- Observational study involving divers exposed to hyperbaric environments.
- Monitoring tremor severity at increasing simulated diving depths.
Main Results:
- Tremor was observed starting at a depth of 150 meters (16 ATA).
- Tremor intensity progressively increased with greater pressure exposure.
- Both central and peripheral nervous system involvement is suggested.
Conclusions:
- Tremor is a significant symptom of HPNS, appearing at 150m and increasing with depth.
- Pathogenic mechanisms likely involve central neural pathways and peripheral factors, such as interstitial pressure changes.
