“…However, only 25.7% of the centers in this survey required patients to measure their BP at home. According to recent publications, the standard Doppler measurement systems may not be ideal for home use because measurements depend on operator experience and can more closely reflect systolic BP rather than mean arterial pressures for nonpulsatile patients (15,16). Alternative Outpatient management of HVAS patients from a VAD coordinator survey 556 systems such as the Terumo Elemano (Terumo Medical Corp.) have been recommended because their accuracy and relative inexpensiveness (15) could make them cost effective for home use.…”

“…2. Woldendorp et al 11 examined sphygmomanometry combined with finger pulse oximetry to measure blood pressure in RBP recipients. In total, 98% of all measurements were successful and Bland-Altman analysis indicated a mean difference of 3.2 mmHg and a standard deviation (SD) of 7.3 mmHg compared to invasive intra-arterial recordings.…”

In rotary blood pump recipients with low blood pressure pulsatility, current oscillometric methods to measure blood pressure are not applicable. The aim of this study was to use ultrasonic Doppler flow measurements to determine blood pressure in this patient population noninvasively. In 28 rotary blood pump recipients, blood pressure was measured three times with the developed Doppler method and compared to the invasive arterial line (n = 15) or to the oscillometric Terumo Elemano BP monitor (n = 13). Blood velocities in the radial artery were recorded by the new Doppler sensor during cuff deflation. A sigmoid curve was fitted to a preprocessed velocity signal and the systolic and mean arterial pressures were determined. A total of 84 measurements were performed, and 17 recordings were visually excluded from further analysis due to obvious artifacts. Both the systolic and mean pressures derived by the Doppler method were in good accordance with the invasively measured pressure (3.7 ± 6.6 mmHg for the systolic and −2.1 ± 7.3 mmHg for the mean pressure). A good agreement between the oscillometric monitor and the Doppler method for the systolic (0.0 ± 6.0 mmHg) and mean (1.0 ± 5.9 mmHg) pressures was observed. In this study, a new Doppler blood pressure measurement system was developed and clinically validated. The novel sensor allows easier placement above the radial artery compared to commercial probes. An algorithm was developed which processes the Doppler signal robustly and is able to determine the systolic as well as the mean arterial blood pressure.
