Table 2. Hemodynamic Data for Each Ventilatory Setting

Values are mean ± SD. Δ 1:1 represents the difference between PC-IRV 1:1 and baseline PCV 1:2 (1). Δ 2:1 represents the difference between PC-IRV 2:1 with baseline PCV 1:2 (1) for patients with sequence A, and difference between PC-IRV 2:1 with baseline PCV 1:2 (2) for patients with sequence B. Δ 4:1 represents the difference between PC-IRV 4:1 with baseline PCV 1:2 (2) for patients with sequence A, and difference between PC-IRV 4:1 with baseline PCV 1:2 (1) for patients with sequence B.

CO = cardiac output; HR = heart rate; ABPs = systolic arterial pressure; ABPm = mean arterial pressure; PAPs = systolic pulmonary arterial pressure; PAPm = mean pulmonary arterial pressure; PCWP = pulmonary capillary wedge pressure; CVP = central venous pressure; SVRI = systemic vascular resistance index; PVRI = pulmonary vascular resistance index.
