Urine Output Response to Fluid and Diuretic Therapy in Cardiac ICU Patients Monitored With FIZE kUO®

The study involves adult patients undergoing coronary artery bypass graft (CABG) or valve replacement/repair surgeries. Utilizing the FIZE kUO® device, continuous urine output data will be collected to analyze responses to hemodynamic interventions, including fluid boluses and diuretics. Secondary objectives include assessing urine output differences in patients with and without postoperative acute kidney injury (AKI), responses to vasopressors, and capturing real-time urine output data from FIZE kUO® for observational analysis.
