Dynamic arterial elastance as a predictor of arterial pressure response to fluid administration: a validation study

Table 2 Effects of volume expansion in hemodynamic variables according to mean arterial pressure increase ^a

^aResponders are defined by a mean arterial pressure (MAP) increase ≥10%). Data are expressed as mean ± SD. ^bP-values refer to group (responder vs. non-responder) and time (preinfusion vs. postinfusion) interaction using analysis of variance for repeated measurements. ^cP <0.05 vs. before volume expansion. ^†P <0.05 vs. non-responders. CO, Cardiac output; CPO, Cardiac power output (mean arterial pressure × cardiac output/451); DAP, Diastolic arterial pressure; MAP, Mean arterial pressure; PP, Pulse pressure (systolic pressure minus diastolic pressure); PPV, Arterial pulse pressure variation; SAP, Systolic arterial pressure; SV, Stroke volume; SVV, Stroke volume variation.
