- Abstract
- Aim: This study investigated the correlation between response time of the 1-back task and changes of blood oxygen saturation (SpO2) by supplying three different levels of oxygen (21%, 1L/min; 93%, 1L/min; 93%, 5L/min) in the elderly. Methods: A total of 17 older adults (mean age 72.9 +/- 4.7years) participated in the experiment. A 1-back task was used as a cognitive task. The experiment consisted of three phases, which included the adaptation phase (3min) after oxygen administration, the control phase (2min) that maintained a stable condition before the task, and the task phase (2min) where the 1-back task was carried out. SpO2 was measured during each phase. Results: As concentration level and supply of oxygen increased, SpO2 increased and response time of the 1-back task decreased. Conclusion: Highly concentrated oxygen administration can increase SpO2 in the elderly and an increase in cognitive performance, such as a decrease in response time, can be observed.
