摘要低氧血症是儿童肺炎、哮喘、支气管肺发育不良等疾病的常见并发症，快速识别低氧血症对于危重症患儿的处置、管理具有重要意义。脉搏血氧饱和度监测是世界卫生组织公认的监测儿童低氧血症的最佳方式，可无创、持续性监测脉搏血氧饱和度。现基于国内外相关文献，并结合儿科临床需求，制定《儿童脉搏血氧饱和度监测临床应用专家共识》，旨在提升儿科医师和护理人员对脉搏血氧饱和度监测的儿科常见应用、作用原理、操作技术以及局限性的认识。

abstractsHypoxemia is a common complication of pneumonia, asthma, and bronchopulmonary dysplasia in children.Rapid identification of hypoxemia is of great significance for the disposal and management of critical children.Pulse oximetry is recognized by the World Health Organization as the best way to monitor hypoxemia in children, and it can monitor pulse oxygen saturation noninvasively and continuously.Based on the related literature at home and abroad, combined with the clinical needs of pediatrics, the " Expert consensus on clinical application of pulse oximetry in children" is formulated to improve the understanding of pediatricians and nurses on the application in pediatric clinical practice, principle, operation techniques, and limitations of pulse oximetry.
