Oxygen saturation, measured by pulse oximetry (SpO), is a vital clinical measure. Our descriptive, cross-sectional study describes SpO measurements from 6289 healthy subjects from age 1 to 80 years at 15 locations from sea level up to the highest permanent human habitation. Oxygen saturation measurements are illustrated as percentiles. As altitude increased, SpO decreased, especially at altitudes above 2500 m. The increase in altitude had a significant impact on SpO measurements for all age groups. Our data provide a reference range for expected SpO measurements in people from 1 to 80 years from sea level to the highest city in the world.
血氧饱和度(SpO)通过脉搏血氧仪测量,是一项重要的临床指标。本描述性、横断面研究描述了从海平面到世界上最高的人类永久居住地的 15 个地点的 6289 名健康受试者的 SpO 测量值。血氧饱和度测量值以百分位数表示。随着海拔的升高,SpO 下降,尤其是在海拔 2500 米以上。海拔升高对所有年龄段的 SpO 测量值都有显著影响。我们的数据为 1 至 80 岁人群从海平面到世界上最高城市的预期 SpO 测量值提供了一个参考范围。
