The Accuryn Registry Study is an open-ended, global, multi-center, retrospective and prospective, single-arm data collection study with an FDA cleared device. The target population are cardiovascular surgery patients. Physiologic data measurements will be collected from enrolled subjects using electronic medical records and data streams via the Accuryn Monitoring System.

The primary objective of the Accuryn Registry Study is to is to track and analyze changes in physiologic data streams using the Accuryn Monitoring System and correlate these changes to the occurrence of acute kidney injury (AKI) following cardiovascular surgery intervention(s).

The secondary objective is to determine the incidence of IAH and ACS in the cardiovascular surgery population and the correlation of these diagnoses to the diagnosis of AKI.
