If it could help: We reported the ICG data of 100 thirt trimester healthy pregnant patients (Tamás P et al. Effects of central hemodynamics on fetal heart rate patterns. Acta Obstet Gynecol Scand 2007; 86:711-4.) and also in preeclamptic patients in 37 cases (Tamás P et al. Discordant clinical characteristics suggest different pathogenesis of preeclampsia. J Perinat Med 2007: 35(suppl. 2).
This dataset includes, among others, bioimpedance data (but not ICG as in the original question):
