The aim of the present study was to assess the accuracy of an automated oscillometric device (DINAMAP) in measuring ankle-brachial pressure index (ABPI) in the clinical setting. Results were then compared to those obtained using the standard Doppler technique.
A prospective comparative study of 50 healthy volunteers was carried out using a standard ward DINAMAP machine, hand-held Doppler and a 14 cm sphygmomanometer cuff. Three consecutive pressure readings were taken from all four limbs of the volunteers using both Doppler and DINAMAP techniques. The two techniques were carried out by different investigators who were blind to the findings of the other. The ABPI was calculated for each technique and the two techniques were compared.
There was no significant agreement between the ABPI readings obtained by DINAMAP and those obtained by the standard Doppler technique. There was also a substantial variation in pressure readings produced by the DINAMAP for a given limb as measured by intraclass correlation of the three readings taken.
There is no role for standard automated oscillometric devices in the calculation of ABPI in the vascular clinic.
本研究旨在评估自动示波装置（DINAMAP）在临床环境中测量踝臂血压指数（ABPI）的准确性。然后将结果与使用标准多普勒技术获得的结果进行比较。
使用标准病房的DINAMAP机器、手持式多普勒仪和一个14厘米的血压计袖带，对50名健康志愿者进行了一项前瞻性比较研究。使用多普勒和DINAMAP技术从志愿者的所有四肢连续读取三次血压值。这两种技术由不同的研究人员进行，他们对对方的结果不知情。计算每种技术的ABPI并比较这两种技术。
DINAMAP获得的ABPI读数与标准多普勒技术获得的读数之间没有显著一致性。通过对三次读取值的组内相关性测量，DINAMAP对给定肢体产生的血压读数也存在很大差异。
在血管诊所计算ABPI时，标准自动示波装置没有作用。
