[Individual differences and individual norms in automated preflight medical checkup]

This paper describes the basic principles, methods and results of preflight automatic medical monitoring. Individual variations of statistic characteristics of the distribution of heart rate, blood pressure, oculomotor reaction time, pursuit reaction quality and other psychophysiological parameters were investigated. Group and individual norms were established. It was found that the sensitivity of group norms was 23 to 65% for different parameters and their prognostic value was 17 to 38%. It is important to assess statistic characteristics of the individual norm in order to identify individuals with latent prepathological and pathological states. Recommendations concerning the applicability of individual norms in early diagnosis, occupational psychological selection and control of operator's activities are given.
