HR = heart rate, MAP = mean arterial pressure, MPAP = mean pulmonary artery pressure, PaO₂ / FiO₂ = arterial partial oxygen pressure divided by the fraction of the inspired oxygen, SVR = systemic vascular resistance, PVR = pulmonary vascular resistance, dyn. compl. = dynamic compliance, sd = standard deviation.
