Data is shown as () or median (25th and 75th percentiles). HR: heart rate; SBP: systolic blood pressure; DBP: diastolic blood pressure; MBP: mean blood pressure; SVV: stroke volume variation; SVI: stroke volume index; CI: cardiac index; CVP: central venous pressure; R: responders; NR: nonresponders. ^a compared with that before fluid challenge; ^b compared with responders.
