  1. aResponders were defined as mean arterial pressure increase ≥10% after fluid administration. Data are expressed as mean ± SD. bP-values refer to group (responders vs. non-responders) and time (preinfusion vs. postinfusion) interaction using analysis of variance for repeated measurements. cP <0.0001 vs. non-responders. dP <0.0001 vs. before volume expansion. C, Net arterial compliance; Ea, Effective arterial elastance; Eadyn, Dynamic arterial elastance; SVR, Systemic vascular resistance.
