ΔPP, pulse pressure variation; ΔRAP, variation in right atrial pressure; PaCO2, arterial partial pressure of CO2; PaO2, arterial partial pressure of oxygen; PAOPee, pulmonary arterial occluded pressure at end-expiration; PAP, pulmonary arterial pressure; RAPee, right atrial pressure at end-expiration; SaO2, arterial oxygen saturation; SvO2, mixed venous oxygen saturation. Ranges in parentheses are 25th to 75th centiles. ap < 0.05 between the two groups.
