Cardiac output after cardiopulmonary bypass [ Time Frame: Less than 10 minutes ] [ Designated as safety issue: No ]
Cardiac output will be measured using an ultrasound dilution technique and compared with cardiac output measured using thermodilution after the completion of surgical procedures involving cardiopulmonary bypass.

Cardiac output before cardiopulmonary bypass [ Time Frame: Less than 10 minutes ] [ Designated as safety issue: No ]
Cardiac output will be measured using an ultrasound dilution technique and compared to cardiac output measured using thermodilution. This will serve as a baseline measurement of the patient's cardiac output.

Measurement of Cardiac Output Before and After Cardiopulmonary Bypass.
Ultrasound Dilution Measurement of Cardiac Output Before and After Adult Cardiopulmonary Bypass
Cardiac output, the amount of blood pumped by the heart in one minute, will be measured in adults undergoing surgery involving cardiopulmonary bypass. Cardiac output will be measured before and after cardiopulmonary bypass using a device that employs ultrasound dilution technology. The ultrasound dilution cardiac output measurements will be validated or compared with cardiac output measurements made using thermodilution, which is the current "gold standard."
