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

FIZE kUO® is a commercially available, non-invasive device used for continuous, minute-by-minute real-time urine output monitoring in patients with an indwelling Foley catheter. In this observational study, the device is used during and after cardiac surgery as part of routine clinical care. Urine output data, along with additional clinical parameters, are collected throughout the study for research analysis.
