  1. C: new arterial compliance; Ea: effective arterial elastance; Eadyn: dynamic arterial elastance; TSVR: total systemic vascular resistance. Data are presented as mean ± standard deviation. Data normally distributed according to Kolomogorov-Smirnov test. Note that pressure units are expressed as cmHg for convenience. *p<0.05 vs baseline. p<0.05 vs. change in arterial pressure. *p value refers to ANOVA test for time and group interaction
