Non-invasive assessment of stroke volume and cardiovascular parameters based on peripheral pressure waveform
Fig 4
Comparison between the model-estimated (computed) stroke volume (SV) and bioimpedance-based (measured) SV values for (a) control group and (b) HD patients (data shown separately for the HD sessions after a long and short interdialytic break).
Solid and dashed lines represent linear regression, and 95% confidence intervals, respectively.
