Abstract

The PS-501 device (Parama-Tech, Fukuoka, Japan), an automated device for office blood pressure measurement based on the Korotkoff method and designed for professional use in clinical settings, was validated. Consecutive outpatients with hypertension and ≥30 years old at an outpatient hypertension clinic were recruited. According to the European Society of Hypertension protocol, 33 participants were included in the validation study (phase 1, n = 15; phase 2, n = 18). The cuff deflation rate can be selected manually from 2, 3, and 4 mm Hg/beat. The validation was performed with the device deflating at a rate of 2 mm Hg/beat. All blood pressure readings were measured on the left arm. The tested device passed all criteria for both systolic and diastolic blood pressure measurements. The mean (± standard deviation) differences in systolic and diastolic blood pressure between the tested device and the mean of observer readings were-1.9 ± 4.6 and-2.5 ± 2.9 mm Hg, respectively. The PS-501 device for office blood pressure measurement passed all the validation criteria of the European Society of Hypertension and can therefore be recommended for clinical use in an adult population.
