a Representation of the least significant changes of cardiac index at predefined times: 30 s (s), 45 s, 60 s, 5 min (min), 10 min and 15 min). Individual values (circles) and box plot (lines corresponding to median, upper and lower bars represent 5–95th percentiles). b Representation of the least significant changes of stroke volume index at predefined times: 30 s (s), 45 s, 60 s, 5 min (min), 10 min and 15 min). Individual values (circles) and box plot (lines corresponding to median, upper and lower bars represent 5–95th percentiles). c Representation of the least significant changes of pulse pressure variation at predefined times: 30 s (s), 45 s, 60 s, 5 min (min), 10 min and 15 min). Individual values (circles) and box plot (lines corresponding to median, upper and lower bars represent 5–95th percentiles). d Representation of the least significant changes of stroke volume variation at predefined times: 30 s (s), 45 s, 60 s, 5 min (min), 10 min and 15 min). Individual values (circles) and box plot (lines corresponding to median, upper and lower bars represent 5–95th percentiles)
