September 8, 2010Blood Pressure Monitoring
A new technique for simultaneous validation of two manual nonmercury auscultatory sphygmomanometers (A&D UM-101 and Accoson Greenlight 300) based on the International protocol
Why the study?
Does simultaneous testing of two nonmercury sphygmomanometers using a Y-tube accurately validate them against a mercury standard?
Population
33 participants, mean age 47.2±14.0 years
Comparison
Simultaneous blood pressure measurement using… vs Mercury sphygmomanometer

Implication
Simultaneous Y-tube testing may efficiently validate nonmercury devices; leaves open whether it replaces sequential protocols.
Structured PICO

P
Population
33 participants, mean age 47.2±14.0 years
I
Intervention
Simultaneous blood pressure measurement using two nonmercury sphygmomanometers (A&D UM-101 and Accoson Greenlight 300) connected by a Y-tube
C
Comparator
Mercury sphygmomanometer
O
Outcome
Device accuracy based on the International protocol of the European Society of Hypertension (measurements within 5/10/15 mmHg of mercury standard)surrogate
Simultaneous testing of two nonmercury sphygmomanometers using a Y-tube is a valid and time-saving method for device validation according to the International protocol.
