Effects of 92% oxygen administration on cognitive performance and physiological changes of intellectually and developmentally disabled people
Journal of physiological anthropology(2015)
摘要
Background The present study addressed how 92% oxygen administration affects cognitive performance, blood oxygen saturation (SpO 2 ), and heart rate (HR) of intellectually and developmentally disabled people. Methods Seven males (28.9 ± 1.8 years) and seven females (34.4 ± 8.3 years) with intellectual and developmental disabilities (disabled level 2.1 ± 0.5) completed an experiment consisting a 0-back task with normal air (21% oxygen) administered in one run and hyperoxic air (92% oxygen) administered in the other run. The experimental sequence in each run consisted of a 1-min adaptation phase, 2-min control phase, and 2-min 0-back task phase, where SpO 2 and HR were gauged for each phase. Results The administration of 92% oxygen increased 0-back task performance of intellectually and developmentally disabled people, in association with increased SpO 2 and decreased HR. Our results demonstrate that sufficient oxygen supply subserving cognitive functions, even as a short-term effect, could increase cognitive ability for the intellectually and developmentally disabled people. Conclusions It is concluded that enriched oxygen can positively affect, at least in the short-term, the working memory of those with intellectual and developmental disability.
