Figure 1.
Right ventricular–pulmonary arterial coupling as estimated by a volume-only method (left) and a pressure-only method (right). Numbers within the symbols are used to denote specific patients to compare the two methods. Optimal mechanical coupling occurs when the end-systolic elastance (Ees) to effective arterial elastance (Ea) ratio is equal to 1, and optimal energy transfer occurs when Ees/Ea falls between 1.5 and 2.0 (9). ESV = end-systolic volume; Pes = end-systolic pressure; Piso = isovolumetric pressure obtained from the single-beat method; SV = stroke volume.
