Objectives: To determine the of undiagnosed lower extremity artery disease using the pulse oximetry in a type 2 diabetic population sample./nMethods: Observational, cross-sectional, descriptive study that included 594 type 2 diabetic patients, with no previous history of lower extremity artery disease. Medical history, physical examination, determination of the ankle-brachial index (portable Doppler) and measurement of oxygen saturation in upper and lower extremities (pulse oximeter) were performed./nResults: Frequency of lower extremity artery disease determined by ankle-brachial index was 18.4%. No significant correlations were detected between oxygen saturation and the ankle-brachial index except for the relationship between ankle-brachial index vs. oxygen saturation at 30 cm lower limb elevation vs. the supine position at no elevation (0 cm) in subjects under the age of 40. Pulse oximetry showed little diagnostic value in the screening of lower extremity artery disease. A relationship between lower extremity artery disease and age has been found. Its diagnosis was associated with a lower body mass index and lower systolic blood pressure in the lower extremities and higher in the upper extremities./nConclusions: We conclude that pulse oximetry is not useful in the screening for asymptomatic lower extremity artery disease in type 2 diabetics.

使用脉搏血氧饱和度和踝臂指数测定 2 型糖尿病患者下肢动脉疾病的频率

目的：使用脉搏血氧饱和度测定 2 型糖尿病人群样本来确定未确诊的下肢动脉疾病。/n方法：观察性、横断面、描述性研究，纳入 594 名既往无下肢病史的 2 型糖尿病患者动脉疾病。进行病史、体格检查、踝肱指数测定（便携式多普勒）以及上肢和下肢血氧饱和度测量（脉搏血氧计）。/n 结果：通过踝肱指数确定下肢动脉疾病的频率为18.4%。在 1 岁以下受试者中，除了踝臂指数与下肢抬高 30 cm 时的氧饱和度与仰卧位不抬高（0 cm）时的氧饱和度之间的关系外，氧饱和度与踝臂指数之间没有检测到显着相关性。 40. 脉搏血氧测定法在筛查下肢动脉疾病方面几乎没有诊断价值。已经发现下肢动脉疾病与年龄之间存在关系。其诊断与下肢较低的体重指数和较低的收缩压以及上肢较高的收缩压有关。/n结论：我们得出的结论是，脉搏血氧测定法对于筛查 2 型无症状下肢动脉疾病没有用处。糖尿病患者。
