The main aims of the project are to:
(1) Validate NIRS readings against standard blood-gas exams for monitoring oxygenation status, hemoglobin concentration, and lactate during cardiac surgical procedures withcardiopulmonary bypass;
(2) Validate NIRS readings as a means to detect insufficient myocardial protection during cardioplegia administration in a swine model of cardiopulmonary bypass;
(3) Explore the potential role of NIRS profiling in the detection of coagulation disorders and excessive inflammatory activation during cardiopulmonary bypass;
(4) Explore the potential of percutaneous application for proof-of-concept point-of-care;
(5) Establish a mechanistic association of molecular biomarkers and clinical status with NIRS signal patterns;
(6) Develop and deploy predictive models. |
