Fig. 2.29 Change in the force-duration dependence of an isolated nerve before (•) and after ()
single exposure of hyperbary (1 atm. within one minute). Along ordinate axis is voltage of threshold
stimulations (volts); along abscissa axis is duration of electric pulse. Reprinted from [136] with

Fig. 2.30 Change in the amplitude of the action potential of an isolated nerve before (•) and after
() exposure of hyperbary (shaded area—1 atm. within 1 min), along ordinate axis is amplitude of
the action potential; along abscissa axis is time pulse. Reprinted from [136] with permission
parameters was most typical for the majority of the examined nerves. A higher degree
of hyperbary (up to 2 atm.) and longer in time can lead to excitability suppression till the full disappearance of the action potential (Fig. 2.31). Meanwhile as the
data presented in the figure show, the action potential amplitude of a fresh isolated
nerve may not undergo substantial changes before as well as during hyperbary and
