Figure 1 The plots of Rp against Qp/Qs show an inverse relationship (A), whereas the plots of Cp against Qp/Qs show a linear proportional relationship (B). Rp, Pulmonary arterial resistance; Qp, pulmonary blood flow; Qs, systemic blood flow; Cp, pulmonary arterial compliance.

Figure 2 The relationship between pulmonary arterial resistance (Rp) and compliance (Cp) before (closed circles) and after (open circles) surgery (A); individual changes are shown as connecting lines (B). The plots of the logarithms of Rp (ln Rp) and Cp (ln Cp) show a linear relationship (C).

Figure 3 The relationship between pulmonary arterial resistance (Rp) and compliance (Cp) is influenced by the amount of pulmonary blood flow and the condition of the pulmonary vasculature.
