Figure 1

Overview. The figure shows a conceptualised overview of the process described in this paper and further implications. From the many measured left cardiac elastance (e(t)) waveforms, alone with many aortic pressure (P ao ) waveforms, correlations are derived (the information flow is shown through the large grey arrow). Once these correlations are known, they can be used along with the aortic pressure waveform (from a patient), to arrive at an estimation of their cardiac elastance waveform. The equivalent for the right cardiac elastance is also shown, with the pulmonary artery pressure (P pa ).
