N2 - A high performance portable automatic sphygmomanometer, the Terumo ES-H51 (104 g, 58 x 22 x 92 mm), was newly developed for clinical use as a substitute for auscultation using a mercury sphygmomanometer. This device usually displays blood pressure (BP) values obtained by the Korotkoff sound method (K-method). However, when the device judges that BP values obtained by the K-method are inaccurate or unreliable, it substitutes automatically BP values obtained by the cuff-oscillometric method (O-method). The accuracy and reliability of the device was tested by comparing it to the auscultation with the standard mercury sphygmomanometer. The mean difference between BP values obtained by the standard method and those obtained by the K-method were -0.7 ± 2.9 mm Hg systole (mean ± SD) and -0.3 ± 2.6 mm Hg diastole, whereas the difference between the former and those obtained by the O-method were 0.3 ± 5.7 mm Hg systole and 0.3 ± 4.3 mm Hg diastole (n = 170). The agreement between the BP values obtained according to each of the two methods using the device and the standard method was within 5 mm Hg for 72% to 93% of both systolic and diastolic readings. Therefore, BP values measured by the ES-H51 are accurate. The ES-H51 is sufficiently small and light to be carried easily anywhere. The objective and reproducible BP information obtained by the present device would be useful in clinical practice. Am J Hypertens 1994;7: 255-260.
