由于光吸收问题，FDA 会审查深色肤色下脉搏血氧计的准确性。 FDA reviews pulse oximeter accuracy in darker skin tones due to light absorption concerns.
美国食品和药物管理局 (FDA) 正在审查脉搏血氧计对于深色肤色人群的准确性。 The Food and Drug Administration (FDA) is reviewing the accuracy of pulse oximeters for people with dark skin tones. FDA 顾问小组于 2023 年 2 月 3 日召开会议，讨论如何提高这些设备针对深色皮肤个体的准确性和性能。 An FDA advisory panel met on February 3, 2023, to discuss ways to improve the accuracy and performance of these devices for individuals with darker skin. 脉搏血氧计是指尖夹具，使用光束来估计氧饱和度和脉搏率。 Pulse oximeters are fingertip clamps that use light beams to estimate oxygen saturation and pulse rate. 研究表明，较深的皮肤色素沉着会影响传感器的光吸收，导致结果不准确，并可能延迟护理或漏诊。 Research has shown that darker skin pigmentation can affect light absorption by the sensors, leading to inaccurate results and potentially delayed care or missed diagnoses.
