Abstract

The purpose of this study was to examine differences between 20s and 60s in blood oxygen saturation due to 93% oxygen administration of the three levels(1L/min, 3L/min, 5L/min). Ten 20s male($25.0{\pm}1.8$ years), ten 20s female($23.7{\pm}1.9$ years), ten 60s male($68.0{\pm}2.6$ years), and ten 60s female($65.5{\pm}3.1$ years) were selected as the subjects for this study. The oxygen supply equipment(OXUS Co.) provided oxygen by supply rate(i.e., 1L/min, 3L/min, and 5L/min) at a constant rate of 93% oxygen. The experiment consisted of three phases, i.e., Prehyperoxia(5min), Hyperoxia(10min), and Post-hyperoxia(5min). Blood oxygen saturation were measured throughoutthe three phases. By increasing the amount of highly concentrated oxygen administration, blood oxygen saturation was increased. Blood oxygen saturation of 20s was higher than 60s. Blood oxygen saturation was greater during Hyperoxia than during Pre- and Post-hyperoxia. However, rising rate of blood oxygen saturation of 60s by oxygen administration was higher than 20s.

본 연구는 93% 고농도 산소의 세 가지 공급량(1L/min, 3L/min, 5L/min)에 대해 20대 및 60대의 혈중산소 포화도의 차이를 규명하고자 하였다. 20대 남자 10명($25.0{\pm}1.8$세)과 여자 10명($23.7{\pm}1.9$세), 60대 남자 10명($68.0{\pm}2.6$세)과 여자 10명($65.5{\pm}3.1$세)의 피험자를 대상으로 실험을 수행하였다. 1L/min, 3L/min, 그리고 5L/min의 유량 변화가 가능하면서 순도 93%의 산소 농도를 일정하게 유지 할 수 있는 산소 공급 장치(OXUS Co.)를 사용하였다. Pre-hyperoxia(5분), 93%의 Hyperoxia(10분), Post-hyperoxia(10분)의 세 단계의 순서로 실험이 진행되었고, 전 단계에서 혈중 산소 포화도가 측정되었다. 유량이 증가할수록 혈중 산소 포화도는 증가하였고, 60대보다 20대의 혈중 산소 포화도가 더 높았다. 안정 상태(Pre-/Post-hyperoxia)에 비해 고농도 산소를 공급한 Hyperoxia 구간에서 혈중 산소 포화도가 증가하였다. 그러나 고농도 산소 공급으로 20대에 비해 60대의 혈중 산소 포화도의 증가량이 더 컸다.
