The purpose of this study was to compare pulse oximetry with ankle and toe pressure measurements in a group of 25 patients with lower limb ischaemia. Measurements were performed on 49 limbs. Pulse oximetry recordings from the second toe were obtainable in only 28 (57%) cases. With lower ankle or toe pressure and more severe symptoms, oximetry was less likely to be possible. In all cases of successful recordings, the oxygen saturation at second toe level was identical with the finger saturation. These data indicate that pulse oximetry has no value in the assessment of peripheral arterial occlusive disease.
本研究的目的是比较25例下肢缺血患者的脉搏血氧饱和度测定与踝部和趾部压力测量结果。对49条肢体进行了测量。仅在28例（57%）病例中获得了来自第二趾的脉搏血氧饱和度记录。踝部或趾部压力较低且症状较严重时，血氧饱和度测定更不易进行。在所有成功记录的病例中，第二趾水平的氧饱和度与手指饱和度相同。这些数据表明，脉搏血氧饱和度测定在外周动脉闭塞性疾病评估中无价值。
