Abstract
This study investigated the effect of 30% oxygen administration on memory
cognitive performance, blood oxygen saturation, and heart rate. Ten healthy male
and female college students (male: 25.8+/-0.8 years, female: 24.2+/-1.9 years)
participated in the study. The results of the memory performance analysis reveal
that word recall rates were enhanced with 30% oxygen administration compared to
21% oxygen. When 30% oxygen was supplied, blood oxygen saturation was increased
and heart rate was decreased compared to that with 21% oxygen administration.
Significant positive correlations were found between changes in oxygen
saturation and heart rate and memory performance. This result supports the
hypothesis that 30% oxygen administration would lead to increases in memory
performance.
