Brief summary

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.

Design outcomes

Primary

Measure	Time frame	Description
Cardiac output after cardiopulmonary bypass	Less than 10 minutes	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.

Secondary

Measure	Time frame	Description
Cardiac output before cardiopulmonary bypass	Less than 10 minutes	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.
