Sentence examples for peak forward pressure from inspiring English sources
An example of a pressure waveform separated into forward and backward components, with and without inclusion of the reservoir pressure, is shown in Fig. 2. Accounting for the reservoir pressure markedly reduced peak backward (reflected) pressure by 88% (P < 0.001), peak forward pressure by 33% (P < 0.001), and the reflection coefficient by 81% (P < 0.001, Table 2).
When the pressure constituents of the AIx were calculated ignoring the arterial reservoir, the peak backward (reflected) pressure component of the augmentation pressure was larger than the peak forward pressure component (16.2 ± 7.6 vs. 6.5 ± 9.4 mmHg, P < 0.001, Table 2) and backward pressure comprised 71% of the AIx (Fig. 3, left).
After we took account of the reservoir, the contribution to augmentation pressure of the backward wave was reduced by 64% to 5.8 ± 4.4 mmHg (P < 0.001), forward pressure was negligible, and reservoir pressure was the largest component (peak pressure = 19.8 ± 9.3 mmHg).
17 Aortic flow was quantified using cross-sectional phase contrast images with contouring of the aortic lumen to provide a peak forward flow velocity (m/s), forward flow volume (ml), backward flow volume (ml) for the calculation of trans-valvular pressure gradient (Bernoulli equation) and regurgitant fraction.
Second, moving clockwise around the circle corresponds to moving this peak forward through the 24‐h period.
Then, the time-domain reflection factor was derived as the amplitude ratio of the backward-to-forward peak pressure wave using the method proposed by Westerhof et al. [ 30].
Resistance was calculated from the formula: Resistance = (Peak pressure-Plateau pressure)/Flow.
As the peak-to-peak pressure of the compressor increased, the peak-to-peak displacement of the displacer increased.
Peak pressure readings, mean pressure ratio, and peak pressure ratio for the different materials were compared.
The radial augmentation index (RaAIx) was calculated as follows: (second peak radial systolic pressure [SBP2] − diastolic pressure)/(first peak radial systolic pressure − diastolic pressure) ×100.
peak inspiratory pressure.
