Unverified指夹式血氧仪对低灌注人群（低血压、末梢循环差、老年人、寒冷环境）读数不稳定，这类人群应选择带'低灌注指数(PI)显示'或'抗运动干扰'技术的型号，PI值＜0.4时读数普遍不可信82% similarUnverified指夹式血氧仪对灌注低（末梢冰凉、老人、休克）人群误差可达±3%以上，慢阻肺/心衰患者建议选带灌注指数PI显示的型号，PI<0.4时读数不可信79% similarUnverified袜式血氧监护仪的核心技术是反射式脉搏血氧仪，其在婴儿低灌注、末梢循环弱状态下的读数准确性低于医院透射式指夹，数值仅作趋势参考78% similarUnverified监测血氧的婴儿手环应采用医用级反射式光电传感器（PPG），血氧SpO2误差需≤2%，心率误差≤5bpm，低于此精度的产品仅能作为趋势参考而非健康预警77% similarUnverified婴儿血氧监测设备应选用医用级PPG光学传感器且采样率≥25Hz的产品，低采样率在婴儿快速活动或哭闹时血氧读数漂移严重，容易产生误报警77% similar
