[280] SCENARIO-BASED QUANTIFICATION OF SLOW ONSET HYPOXIA-INDUCED PILOT VISUAL BEHAVIOR

摘要

INTRODUCTION: The purpose of this study was to measure the flight-related visual behavior in hypoxic pilot participants as a percentage of their normoxic baseline at different SpO_2 levels. It was of particular interest to investigate the effect of hypoxia on visual behavior as measured using eye-tracking. It was hypothesized that as SpO_2 levels decreased, time to acquire visual targets would increase. METHODS: The study used a within-subjects design; SpO_2 level was the independent variable. Participants (n = 14; 13 males and 1 female) were commercial instrument rated pilots with 40 hours of G-1000 time. Approval from the researchers'institutional review board was obtained. Each participant wore a head-mounted eye-tracker and sat at the console of a G-1000 located inside a hypobaric chamber.
