Abstract
INTRODUCTION: Auscultatory nonmercury manual devices seem good alternatives for the mercury sphygmomanometers in the clinic and for research settings, but individual internal validation of each device is time-consuming. The aim of this study was to validate a new technique capable of testing two devices simultaneously, based on the International protocol of the European Society of Hypertension.
METHODS: The concept of the new technique is to measure blood pressure alternatively by two observers using a mercury sphygmomanometer and by two observers using the A&D UM-101 and Accoson Greenlight 300 devices, connected by Y-tube to obtain simultaneous readings with both nonmercury devices. Thirty-three participants were enrolled (mean age 47.2±14.0 years). Nine sequential blood pressure measurements were performed for each participant.
RESULTS: Both devices passed phase 1 using 15 participants. In phase 2.1 (n=33), on a maximum of 99 measurements, the Accoson device produced 81/95/99 measurements within 5/10/15 mmHg for systolic blood pressure (SBP) and 87/98/99 for diastolic blood pressure (DBP). The A&D device produced 86/96/99 for SBP and 94/99/99 for DBP. In phase 2.2 (n=33), 30 participants had at least 2 out of 3 SBP obtained with Accoson device within 5 mmHg of the mercury device, as compared with 29 of 33 participants with the A&D device. For DBP, this was 33 of 33 participants for both devices.
CONCLUSION: Both the nonmercury devices passed the International protocol. The new technique of simultaneous device testing using a Y-tube represents a time saving application of the International protocol.
