几家脉搏血氧计制造商最近开发了一种声称能抵抗病人运动影响的仪器。我们进行了一项实验室志愿者实验，比较了其中几种仪器以及一些旧型号在运动和低氧血症组合时的性能。研究了20个血氧计。一个电动桌子产生不同的手部动作，在室内空气呼吸和低氧血症的情况下，每个动作都被研究。在不活动的手上使用脉搏血氧仪作为对照测量。Masimo SET(R)脉搏血氧仪表现出最佳的整体性能，其性能指数（Spo(2)读数在控制值7%以内的时间百分比）为94%。其次是Agilent Viridia 24C，指数为84%，其次是Agilent CMS（80%）、Datex-Ohmeda 3740（80%）和Nellcor N-395（69%）。与较早的血氧仪技术相比，Criticare 5040的指数为28%。最近的技术变化显著提高了运动伪影期间脉搏血氧仪的性能，其中Masimo血氧仪处于领先地位。
Several pulse oximeter manufacturers have recently developed instruments that are claimed to be resistant to the effects of patient motion. We performed a laboratory volunteer experiment to compare the performances of several of these instruments, as well as some older models, during combinations of motion and hypoxemia. Twenty oximeters were studied. A motorized table produced different hand motions, and each motion was studied during both room air breathing and hypoxemia. Pulse oximeters on the nonmoving hand were used to provide control measurements for comparison. The Masimo SET(R) pulse oximeter exhibited the best overall performance, with a performance index (percentage of time in which the Spo(2) reading is within 7% of control value) of 94%. The Agilent Viridia 24C was next, with an 84% index, followed by the Agilent CMS (80%), the Datex-Ohmeda 3740 (80%), and the Nellcor N-395 (69%). For comparison with older oximeter technology, the Criticare 5040 had an index of 28%. Recent technology changes have significantly improved pulse oximeter performance during motion artifact, with the Masimo oximeter leading the way.
