Cerebral Oxymetry at Elective Coronary and Valve Surgery.
Cerebral Oxymetry at Elective Coronary and Valve Surgery: An Observational Study Using Norepinephrine to Maintain Arterial Blood Pressure on Cardio Pulmonary Bypass.
Use of vasopressor to maintain Mean Arterial Pressure on Cardio Pulmonary Bypass can lead to decreased cerebral flow and oxygenation in individual patients and this can be detected by means of cerebral oxymetry.
