Mathematical Analysis of Peripheral Visual Response Time and Associated Effects of Hypoxia

Abstract

A polynomial regressional analysis was performed on the combined data of four previous studies (43 subjects) on the effects of four levels of hypoxia (O2 concentrations of 20.93%, 12.8%, 11.8% and 10.9%, respectively) on response time (RT) to visual flash stimuli distributed in 48 locations about the visual field. The relationship of RT to peripheral stimulus location could be described in all instances by third-degree polynomial power functions, which differed only with respect to meridional location of the stimuli in the visual field. The main effect of hypoxia exposure was elevation of the RT impairment in direct relation to severity, but without changing the functional relationships involved from those observed for normoxic performance.
