Using such a statistical analysis, the researchers estimated the significance level
of different threshold values of isolated nerve stimulation within four electric pulse
durations before, during and after hyperbary impact. The results of the statistical
analysis are shown in Table 2.4. They testify (on the generated significance level
<0.2) the reliable decrease of nerve fibers excitability in the isolated nerve as a result
of hyperbary impact.
2.3.3 Study of Hyperbary Impact on the Nerve Fiber
in the Range of Hydrostatic Pressure of 0–200 Atm.
This study was conducted using a camera, the scheme and the photo of which are
presented in Fig. 2.33.
The camera body 1 was made of stainless steel. For optical measurements, there
were the plane-parallel optical windows 2, 3 made of sintered quartz. The thickness
of the windows was 8 mm, and the diameter was 10 mm. The lower camera window
2 was firmly fixed in its body with the circular section seal ring 4. The Teflon gaskets
5 are located between the camera body and the window in the place of their contact.
