Changes in arterial carbon dioxide tension in patients undergoing on- and off-pump coronary artery bypass grafting surgery. Mean arterial carbon dioxide tensions (PaCO2) and 95% confidence intervals for patients undergoing on- and off-pump patients over time. Where pre-op: pre-operatively, post-grafting: following coronary artery bypass grafting and next-morning: approximately 0600 on the morning following surgery.
