Cardiac Surgery
Conditions
Brief summary
This is a study to validate the utility and accuracy of the non-invasive device (LiDCOrapid monitor) during a period of phlebotomy and graded blood loss in patients who are having cardiac surgery.
Interventions
Technology which provides a continuous means of monitoring various hemodynamic parameters including cardiac output and pulse pressure variability.
Sponsors
Study design
Eligibility
Inclusion criteria
* Patients scheduled for intraoperative phlebotomy following anesthetic induction to obtain autologous blood for use following cardiopulmonary bypass and cardiac surgery.
