Abnormalities in arterial oxygen tension (PO2) and carbon dioxide tension (PCO2) are extremely common in critically ill patients and may lead to serious atrial and ventricular arrhythmias. Routine analysis of arterial PO2, PCO2, and pH in patients admitted to an intensive care unit revealed that only 8% of more than 4,000 studies were completely normal. Mild to moderate hypoxemia was present in 23%, severe hypoxemia (PO2 below 50 mm Hg) in 17%, and respiratory alkalosis in 47%. From a larger group of patients with cardiac arrhythmias and abnormal gas tensions, nine were selected for special study. All had serious arrhythmias,
