Cumulative influence factor (CIF) for compartments (A), controls (B), and heart and lungs (C) groups. In the compartment group (A), the CIF is further divided to show the individual contributions of the different parameters forming a compartment (resistance, length, and compliance). CIF takes a value between 0 and 1 where a higher value represents greater influence on the outcome measures. A, arterial baroreflex; Abd, abdominal; Ao, aorta; Art, arteries; Asc, ascending; BC, brachiocephalic; C, compliance; CP, cardiopulmonary reflex; d, diastolic; Dsc, descending; es, end-systolic; G, gain; IVC, inferior vena cava; la, left atrium; LB, lower body; lc, lower body microcirculation; lv, left ventricle; mit, mitral valve; P, parasympathetic; pa, pulmonary arteries; pc, pulmonary microcirculation; pv, pulmonary veins; R, resistance; ra, right atrium; rc, renal microcirculation; Ren, renal; R-R, R-R interval; rv, right ventricle; S, sympathetic; sc, splanchnic microcirculation; Spl, splanchnic; SVC, superior vena cava; Th, thoracic; tri, tricuspid valve; UB, upper body; ub, upper body microcirculation; V, unstressed volume; Ve, veins.
