摘　　要：氧储备指数(oxygen reserve index,ORI)是一项新型无量纲参数,可无创、实时、持续监测氧合状态,数值范围是0~1,反映的动脉血氧分压范围是100~200 mmHg。ORI和脉搏血氧仪结合使用,有助于准确调整吸入气氧浓度,预防低氧血症和高氧血症。ORI适用于临床各种情况,医务人员应掌握这项新型参数并合理应用,以评估患者的氧合状态。临床应用时应注意ORI的一些不足。Oxygen reserve index(ORI)is a novel dimensionless index used for noninvasive,real-time,and continuous monitoring of oxygenation,and ORI value ranges from 0 to 1,which reflects the range of 100-200 mmHg for arterial partial pressure of oxygen.ORI combined with pulse oximetry may help to accurately adjust the concentration of inspired oxygen and prevent hyperoxemia and hypoxemia.ORI is suitable for various clinical situations,and the medical staff should master this novel parameter and use it properly to assess the oxygenation of patients.In addition,several limitations of ORI should be noticed during clinical application.
