“…As a conclusion, a measurement device with fixed ratios for determining systolic, mean and diastolic blood pressure may significantly overestimate them. [19] Moraes and Cerulli (1999 and 2000) also studied the characteristic ratios using computercontrolled linear cuff pressure deflation with 10 patients and 75 volunteers, using the auscultatory method as a reference [20,21]. A fixed percentile rule yielded a value of 56% for systolic and 76% for diastolic pressure.…”

The gold standard for noninvasive blood pressure (BP) measurement, the Doppler technique, does not provide systolic blood pressure (SBP) and diastolic blood pressure (DBP) and may limit therapy outcomes. To improve patient care, we tested specifically designed experimental BP (ExpBP) monitor and the Doppler technique by comparing noninvasive measures to the intraarterial (I-A) BP in 31 patients with end-stage heart failure (4 females) 2.6 ± 3.4 days post-LVAD implantation (20 HeartMate II and 11 HeartWare). Bland-Altman plots revealed that the ExpBP monitor overestimated mean arterial pressure (MAP) by 1.2 (4.8) mm Hg (mean difference [standard deviation]), whereas the Doppler by 6.7 (5.8) mm Hg. The ExpBP SBP was overestimated by 0.8 (6.1) mm Hg and DBP by 1.9 (5.3) mm Hg compared with the respective I-A pressures. Both techniques achieved similar measurement reliability. In the measurement "success rate" expressed as a frequency (percent) of readable BP values per measurement attempts, Doppler accomplished 100% vs. 97%, 97%, and 94% of successful detections of MAP, SBP, and DBP provided by the ExpBP monitor. The ExpBP monitor demonstrated higher accuracy in the MAP assessment than the Doppler in addition to providing SBP and DBP in majority of subjects. Improved BP control may help to mitigate related neurologic adverse event rates.

“…The arterial volume pulse will be at maximum when the transmural pressure is zero, which occur when MAP is equal to cuff pressure [66]. MAP is not commonly estimate on clinical practice and other methods of blood pressure measurements and usually is not presented on the The oscillation or Oscillometric pulses can be extracted from cuff deflation pressure waveform and presented a signal knows as Oscillometric waveform (OMW) [57]. Filtering and deterending are used to extract OMW from cuff deflation pressure waveform [55] [58] [59].…”

“…The non-invasive measurements were done at the opposite arm. As noted above, precision values of SBP and DBP obtained by the oscillometric method are linked to the strategy followed by the algorithms used and their parameters (Moraes and Cerulli 2000;Ehrmann et al 2009). Two methods are commonly used: the method of maximum amplitude and the gradient.…”
