Validation of the computational fetal hemodynamics/gas exchange model for the range of gestational ages under consideration. Please note that the model is rigorously validated for term babies in Ref. [3]. a Combined cardiac output (CCO), solid line: simulated, circle: Rasanen et al. [29], square: De Smedt et al. [31], triangle: Kiserud et al. [18] b) Simulated organ flow distribution as percentage of CCO, asterisk: RVO, plus: LVO, square: DA, cross: PLAC, diamond: FO, right-triangle: CEB, left-triangle: PUL. c Aortic blood pressure. Solid: simulated, dash: clinical [27], red: systolic, black: mean, blue: diastolic. d E/A ratio. Red: mitral, blue: tricuspid, solid: simulated, dash: Hecher [35], dot: Kenny [39]. e Pulsatility index, solid: simulated, dash: clinical, asterisk: DA, diamond: MCA, circle: TAo, right-triangle: UA, square: DV. Clinical values are taken for DA from Mielke et al. [36], MCA from Ebbing et al. [38] and Ferrazzi et al. [24], TAo from Ferrazzi et al. [24], UA from Acharya et al. [37], DV from Hecher et al. [35]. f Simulated oxygen partial pressure in umbilical vessels, red: UV, blue: UA. RVO: right ventricular output, LVO: left ventricular output, DA: ductus arteriosus, PLAC: placenta, FO: foramen ovale, CEB: cerebral, PUL: pulmonary, MCA: middle cerebral artery, TAo: thoracic aorta, DV: ductus venosus, UA: umbilical artery, UV: umbilical vein
