ALB and respiratory failure: More specifically, patients with PerCI have the lower albumin (P<0.001), higher glucose (P<0.001), lower total calcium (P<0.001), higher sodium (P=0.001), lower blood pH (P<0.001), higher heart rate (P=0.001), higher respiratory failure (P<0.001), higher bacteremia (P<0.001), higher pneumonia (P<0.001), lower aortocoronary by pass status (P=0.028), higher sepsis (P<0.001), higher ventricular fibrillation (P=0.038), higher cardiac arrest (P<0.001), higher OASIS score (P<0.001), higher SAPS-II score (P<0.001), and higher SOFA score (P<0.001), as compared to patients without PerCI.
