Impact of arterial load on the agreement between pulse pressure analysis and esophageal Doppler

Table 4 Changes on arterial load parameters and mean arterial pressure throughout different interventions

	Absolute percentage change	Range of percentage change
Mean arterial pressure
Fluid administration	4.29 (1.7 to 8.3)	−18.3 to 44.8
Vasopressor change	11.6 (3.3 to 16.5)^a	−30.9 to 61.6
Total systemic vascular resistance
Fluid administration	5.5 (2.5 to 9.9)	−31.1 to 59.7
Vasopressor change	12.1 (5.2 to 24.5)^a	−38.1 to 132.1
Net arterial compliance
Fluid administration	6.1 (2.7 to 11.3)	−46.5 to 57.6
Vasopressor change	11.4 (5.1 to 21.4)^a	−47.4 to 102.2
Effective arterial elastance
Fluid administration	4.9 (2.4 to 9.4)	−34.4 to 79.6
Vasopressor change	10.3 (4.1 to 20.8)^a	−43.7 to 86.2

Data are expressed as median (25th to 75th interquartile range) or as range. ^aP <0.0001 versus fluid administration.
