Extended Data Fig. 7: Analysis of estimating blood pressure using pulse timing parameters.
a, A representative plot showing large movement in accelerometry data (bottom) correlates to large and sudden changes in arterial line (A-line) derived SBP signal (top). Bland Altman plots of PAT- and PTT-derived SBP compared to A-line SBP from the data shown in b, Fig. 5d (n = 18,679 data points for both left and right), c, Fig. 5e (n = 17,449 data points for both). d, A plot (left) of A-line SBP (red) and PAT SBP (blue) and the resulting Bland Altman plot (right, n = 7,322 data points) for the subject with H/O splenectomy (39 w GA, 95 w CA). e, A plot (left) of A-line SBP (red) and PTT SBP (blue) and the resulting Bland Altman plot (right) for the same subject (n = 7,322 data points).
