为了研究SphygmoCor和OmronHEM 9000-AI设备在估计中心血压（BP）方面的准确性，并与同时进行的有创导管测量进行比较。方法在33例患者中，使用Omron和SphygmoCor设备连续记录桡动脉脉搏，校准肱动脉血压计BP，以获得中心BP，也用基于导管的流体填充压力计系统同时测量。重复三次，以获得99对非侵入性和侵入性measurement.ResultsThe非侵入性中心收缩压估计显着（P < 0.001）与侵入性测量在升主动脉，与相关系数为0.91和0.90的SphygmoCor和Omron设备，分别。然而，两种器械均低估了中心收缩压，SphygmoCor的差异为-15 mm Hg（95%置信区间（CI），-17至-13 mm Hg，P < 0.001），Omron为-2 mm Hg（95% CI，-4至0 mm Hg，P < 0.05）。与肱动脉有创导管测量相比，Omron血压计装置低估了肱动脉收缩压-19 mm Hg（95% CI，-23至-15 mm Hg，P < 0.001）。尽管如此，这些中心BP的无创估计与有创测量密切相关，并且在设备特定诊断阈值可用的条件下仍然可以正确使用。
BackgroundTo investigate the accuracy of the SphygmoCor and Omron HEM9000-AI devices in the estimation of central blood pressure (BP) in comparison with the simultaneous invasive catheter measurement.MethodsThe radial arterial pulse was sequentially recorded by the use of the Omron and SphygmoCor devices in 33 patients, with the calibration of the brachial oscillometric BP, to derive central BPs, which were also measured simultaneously with a catheter-based fluid-filled manometer system. The procedure was repeated three times to obtain 99 pairs of noninvasive and invasive measurements.ResultsThe noninvasive central systolic BP estimations were significantly (P < 0.001) associated with the invasive measurement at the ascending aorta, with a correlation coefficient of 0.91 and 0.90 for the SphygmoCor and Omron devices, respectively. However, both devices underestimated central systolic BP with a difference of -15 mm Hg (95% confidence interval (CI), -17 to -13 mm Hg, P < 0.001) for SphygmoCor and -2 mm Hg (95% CI, -4 to 0 mm Hg, P < 0.05) for Omron. In comparison with the invasive catheter measurement at the brachial artery, the oscillometric Omron device underestimated brachial systolic BP by -19 mm Hg (95% CI, -23 to -15 mm Hg, P < 0.001).ConclusionsBoth devices underestimated central systolic BP, with a larger deviation by SphygmoCor. Nonetheless, these noninvasive estimations of central BP closely correlate with the invasive measurements, and can still be properly used, on the condition that device specific diagnostic thresholds become available.
