Abstract:
Objective:To investigate the effect of 300 m saturation diving at sea on tremor intensity of divers’ finger.Methods:The finger tremor intensities of four divers were measured before entering pressurization chamber, during increasing pressurization, and at the stable stage of 300 m saturation pressurization.Results:The mean values of the tremor intensities of the divers’ fingers during the period from entering the chamber and starting pressurization to the stable stage of 300 m pressurization were higher than that before pressurization; specifically, the increases of tremor intensity of the divers’ fingers were the most significant at 250 m, 270 m, and 290 m pressurization ( P<0.05). However, there was no statistically significant difference in the mean value of the finger tremor intensities between that before pressurization and those at 195 m, 220 m, 250 m, 300 m pressurization, and during the 24 h-stay at the 300 m saturation pressurization ( P>0.05). Conclusion:The monitoring of finger tremor intensity in saturation diving at each pressurization stage can objectively and quantificationally evaluate the onset and development of high-pressure neurological syndrome (HPNS), which, combined with the traditional evaluation method, can provide a basis for improving the saturation diving pressurization rate and ensuring the safety of divers.
