Dry-EEG Indices of Normobaric Hypoxia in Professional Pilots
Abstract
Recent development of dry-electroencephalogram (EEG) technology (i.e., gel-free EEG recording) has provided the potential to move cognitive performance research out of the laboratory into the field since in today's environment, people must operate highly technical equipment safely and effectively. However, the challenge is to evaluate changes in EEG/cognition and other physiological measures in real time. This summary suggests a potential useful method. The series of PCA-ANOVA analyses showed there were a number of "hypoxia" components identified at each frequency with typically the first two components distinctly identifying changes in EEG frequency relative to hypoxia at 20,000 ft. PCA of individual subject's data identified two principal components with the factor scores from at least one component correlating significantly to Sp02 and 02 ROBD2 concentration changes especially at 20,000 ft. with statistically significant, small-to-medium effect sizes (r > .32 to .55) or greater at that altitude.
