Comparison of SVO2, SpO2, and clinical parameters with arterial blood gases during ventilatory weaning after cardiac surgery.
Correlations of mixed venous and arterial oxygen saturation, heart rate, respiratory rate, and mean arterial pressure with arterial blood gas variables were computed for 57 sets of data obtained from 30 postoperative coronary artery bypass graft patients who were being weaned from mechanical ventilation. Arterial oxygen saturation and respiratory rate correlated significantly, although moderately, with blood gases.
