© Continuing Medical Implementation …...bridging the care gap Benefits of Automated BpTRU™ BP Devices –Standardizes BP readings from one operator to the next –Removes many of the errors associated with manual readings –Accurate, reliable and reproducible readings –Multiple readings with averaging – “Opportunistic screening” –Accurate, independently validated device –Automatically zeroes with each inflation –Performs full system check every time on powering-up Performs six readings Discards the first reading Averages the remainder Interval between readings from 1-5 minutes apart User can auscultate using the digital readout when desired

© Continuing Medical Implementation …...bridging the care gap Study Conclusions The patient’s presence in the doctor’s office or research unit in itself appears to be partly responsible for the white coat effect. BP readings taken on the initial visit tend to be higher than other readings. The white coat effect can be partly eliminated by the use of an automated BP recording device (BpTRU) BP readings recorded by the BpTRU device are similar to readings taken by an experienced research technician using CHS Guidelines.

Current evidence suggests that: Blood Pressure and Target Organ Damage (TOD) 24-h blood pressure correlates most closely with TOD (compared to clinic or casual BP) Higher incidence of cardiovascular events when blood pressure remains elevated at night (non-dippers) Blood pressure variability is an independent determinant of TOD Highest incidence of cardiovascular events occurs in AM Adapted from: Sokolow, et al. 1966; Devereux, et al. 1983; Devereux, et al. 1987; Parati, et al. 1987; Mancia
