title: [Voluntary apnea of maximum duration as a model of short-term asphyxia in psycho- and electrophysiological studies].
abstract: We evaluated the test with arbitrary external respiratory standstill (AEKS) of maximum duration as a model of short-term asphyxia. The experiments were carried out in volunteer students. The level of oxyhemoglobin saturation and tissue oxygen tension that we registered in a group of sportsmen in the course of AEKS of maximum duration demonstrated that asphyxia developed in some of the probationers within 100-120 seconds. Taking into consideration the fact that registration of many psychophysiological and electrophysiological parameters takes place within the interval from several hundreds of milliseconds to several tens of seconds AEKS of maximum duration may be regarded as an adequate model of short-term asphyxia.
