Effects of Three Levels of Flow Rate of Highly Concentrated Oxygen Administration on SpO2and HR of 60s Male and Female

This study investigated differences in blood oxygen saturation() and heart rate(HR) according to flow rate, gender, and phase in males and females in their 60s when the supply of 93% highly concentrated oxygen administration was changed (1L/min, 3L/min, and 5L/min). It recruited totally 20 elderly subjects including 10 males( years) and 10 females ( years). The experiment consisted of three phages of Rest 1(5 min), Hyperoxia(10 min), and Rest 2(10 min), and [%] and HR[bpm] were measured during all phages. was higher in Hyperoxia phase supplied with highly concentrated oxygen than in Rest phases. Higher flow rate was associated with more increase in . HR was reduced in Hyperoxia phase compared to Rest phases. More supply of highly concentrated oxygen was associated with more decrease of HR. However, there were no differences in both and HR according to gender.
