Assessment of myocardial protection during global ischemia with myocardial gas tension monitoring.

Intramyocardial gas tension monitoring with mass spectrometry allows for the continuous assessment of myocardial metabolic activity during prolonged global ischemia. With aortic cross-clamping there is a rapid decrease in intramyocardial oxygen tension (PmO2) and a steady increase in carbon dioxide tension (PmCO2). In laboratory studies the extent to which… CONTINUE READING
