This study was designed to assess the use of pulse oximetry (PO) to determine the adequacy of radial and ulnar arterial blood flow by comparing measurements of digital arterial hemoglobin oxygen saturation (SaO2) with conventional visual determination of palmar flush (PF) using a simple occlusion test (SOT) or the Allen's test (AT) in 48 healthy volunteers. Baseline SaO2 values ranged from 94% to 100% with a mean saturation of 97.2%. Eight subjects with initially abnormal reperfusion times were re-evaluated. Of those eight subjects, three remained abnormal. The predictability of an abnormal reperfusion time based on pretesting history was very low. AT reperfusion times as measured by PO and PF showed excellent correlation (r = 0.882). The SOT does not require subject cooperation and provides information similar to the AT. PO, whether combined with the AT or the SOT, has the distinct advantage of providing objective data.
本研究旨在通过比较48名健康志愿者使用简单闭塞试验（SOT）或艾伦试验（AT），以传统视觉判定掌部充血（PF）的方法与数字动脉血红蛋白氧饱和度（SaO2）测量值，来评估脉搏血氧饱和度测定法（PO）用于确定桡动脉和尺动脉血流充足性的情况。基线SaO2值范围为94%至100%，平均饱和度为97.2%。对8名最初再灌注时间异常的受试者进行了重新评估。在这8名受试者中，3名仍为异常。基于预测试病史的异常再灌注时间的可预测性非常低。通过PO和PF测量的AT再灌注时间显示出极好的相关性（r = 0.882）。SOT不需要受试者配合，并提供与AT类似的信息。PO，无论与AT还是SOT结合使用，都具有提供客观数据的明显优势。
